What are holographic films?
Holographic films are specialized materials embossed with microscopic patterns that diffract light, creating a dynamic, three-dimensional, rainbow-like visual effect. They are typically made from polyester (PET) or polypropylene (BOPP) and are often metallized to enhance their brilliance.
How do holographic films work?
They work through the principle of diffraction. A master hologram, created with a laser, is used to stamp (emboss) a complex pattern of grooves onto the film surface. When light hits this pattern, it splits into its constituent colors and reflects at different angles, creating the characteristic shimmering, multi-colored effect.
What is the basic structure of a holographic film?
A standard structure includes:
1) A base substrate (like PET or BOPP), 2) A release coating (for transfer films), 3) A lacquer layer that holds the embossed holographic pattern, 4) A metallization layer (usually aluminum) to reflect light, and 5) An adhesive layer (for self-adhesive or lamination films).
Are holographic films the same as rainbow films?
They are related but not identical. "Rainbow film" often refers to a specific type of holographic film that produces a spectrum of colors without a distinct 3D image. All rainbow films are holographic, but not all holographic films are simple rainbows; they can contain complex 3D images, 2D patterns, and microtext.
What are the different types of holographic films available?
Different types of Holographic Films are Metalized Holographic Films, Transparent Holographic Films, Colour Holographic Films, Holographic Transfer Films, Seamless Holographic Films, Generic Holographic Films, Customized Holographic Films, and Cast and Cure Holographic Films
What is a holographic polyester film?
It is a holographic film where the base substrate is Polyethylene Terephthalate (PET). It is known for its high tensile strength, excellent dimensional stability, clarity, and resistance to heat and chemicals. It's ideal for packaging, labels, and laminates.
What is a holographic BOPP film?
It is a holographic film where the base substrate is Biaxially Oriented Polypropylene (BOPP). It is more flexible and cost-effective than PET and offers excellent moisture barrier properties, making it popular for flexible packaging, especially for food items.
What are the key properties of a good quality holographic film?
Key properties include high diffraction efficiency (brightness), excellent clarity, strong and consistent metallization, good embossing quality, high tensile strength, dimensional stability, and good adhesion for inks and coatings.
Can holographic films be customized?
Yes, extensively. Customization includes the holographic pattern design (2D, 3D, custom logos), the type of substrate (PET, BOPP), the type of metallization (full, semi-transparent, transparent), and the width and length of the rolls.
What is the typical thickness range for holographic films?
Holographic PET films typically range from 12 microns to 50 microns. Holographic BOPP films are often in the 20 to 30 micron range. The choice depends on the required rigidity, flexibility, and application method.
Are holographic films environmentally friendly?
The base materials (PET, BOPP) are recyclable. However, the combination of layers (plastic, metal, adhesive) can complicate recycling. Some manufacturers offer more mono-material, recyclable-friendly structures. The long-term durability and anti-counterfeiting benefits also contribute to sustainability by reducing product waste from fakes.
Are holographic films recyclable?
It depends on the local recycling stream. Standard metallized holographic films are often not accepted in curbside recycling. However, developments are being made in water-based transfer films that allow the holographic layer to be delaminated, leaving a clean, recyclable PET substrate.
What is the shelf life of holographic films?
When stored correctly (in a cool, dry place away from direct sunlight and heat sources), most holographic films have a shelf life of 12 to 24 months from the date of manufacture.
How should I store unused holographic film rolls?
Store them in their original packaging, lying flat on a shelf (not on their end), in a controlled environment with temperatures between 15°C and 30°C and relative humidity below 65%. Protect them from dust and direct sunlight.
What is the difference between a holographic film and a holographic sticker?
A holographic film is the raw material on a roll. A holographic sticker is a finished product made from that film, which is typically printed, die-cut, and supplied on a release liner with a pressure-sensitive adhesive for easy peeling and application.
Can holographic films be used for non-commercial or artistic purposes?
Absolutely. Artists and crafters use holographic films for sculptures, installations, mixed media art, custom apparel, and unique gift wrapping due to their captivating visual properties.
Do you provide holographic film samples before bulk ordering?
Do you provide holographic film samples before bulk ordering?
Yes, we offer sample rolls for testing and approval before you place a large bulk order. This allows you to check the quality, compatibility, and visual effect.
What is the minimum order quantity (MOQ) for holographic films?
MOQ varies by supplier and type of film. For standard patterns, it can be as low as 1 Ton. For custom-designed holograms requiring a new master, the MOQ is significantly higher to amortize the master origination cost.
What are the primary applications of holographic films?
The primary applications are: 1) Packaging (flexible & mono cartons) for branding, 2) Labels for premiums and security, 3) Anti-counterfeiting and brand protection, 4) Lamination for textiles and documents, and 5) Promotional materials.

Can holographic films be used for food packaging?
Yes, but it is crucial to use films that are compliant with relevant food safety regulations. Holographic BOPP films are extremely common for food items like snack packets, as they often meet these requirements and provide a good moisture barrier.
Are holographic films FDA compliant for direct food contact?
Some are. You must specifically request films that are manufactured with FDA-compliant inks, lacquers, and adhesives if they will be in direct contact with food. The supplier should provide a certificate of compliance.
How are holographic films used for brand protection and anti-counterfeiting?
They are a powerful overt security feature. Custom holograms with intricate designs, microtext, and hidden images are very difficult and expensive to replicate accurately, making them a strong deterrent against counterfeiters.
What makes holographic films a good security feature?
Their security lies in the complexity of the origination process (requires a master hologram), the difficulty of high-quality embossing, and the ability to incorporate covert features (e.g., microtext, UV verifiable images) that are invisible to the naked eye.
Can holographic films be used on pharmaceutical packaging?
Yes, they are widely used on pharmaceutical packaging to prevent drug counterfeiting. They are applied to labels, cartons, and blister packs to ensure product authenticity and patient safety.
How are holographic films used in labels?
They are used as the face stock material for labels. They can be printed and converted into prime labels (the main product label), promotional labels ("limited edition"), authentication labels, and tamper-evident seals.
Can holographic films be used for gift wrapping?
Yes, holographic films are popular for high-end, decorative gift wrapping and gift bags due to their spectacular visual appeal. They are more durable and premium-looking than standard wrapping paper.
How are holographic films used in the printing industry?
Printers use them as a substrate for flexographic printing to create stunning visual appeal for variety of products
Can you print on holographic films?
Yes, holographic films are excellent printing substrates. The key is to use printing methods and inks that complement rather than completely obscure the holographic effect.
Is flexographic printing suitable for holographic films?
Yes, flexo printing is highly suitable. It allows for high-speed production and good quality on holographic substrates, especially for packaging and label applications.
What type of printing is best for holographic films?
Flexographic and rotogravure printing are most common for high-volume runs. UV printing is increasingly popular for its excellent adhesion and ability to print white and opaque inks.
Can you use offset printing on holographic films?
It is less common but possible. The smooth, non-porous surface of holographic film can present challenges for some offset inks regarding drying and adhesion. UV-curable offset inks are a better option.
Is rotogravure printing suitable for holographic films?
Yes, rotogravure is excellent for holographic films. It provides superior ink density, vibrant colors, and consistent high-quality reproduction, making it ideal for premium packaging.
What are the challenges of printing on a holographic surface?
The main challenges are ensuring ink adhesion to the often non-porous, metallic surface, and managing the design to balance opaque areas with transparent areas that let the holography shine through.
Do I need special inks for printing on holographic films?
Generally, yes. Inks with strong adhesion properties are required. UV-curable inks, electron-beam (EB) curing inks, and specially formulated solvent-based inks for non-porous substrates are typically recommended.
Should I use transparent or opaque inks on holographic films?
It depends on the desired effect. Transparent inks (varnishes) are used to tint the hologram without hiding it. Opaque inks (especially white) are used as a base layer to make other colors pop or to create solid areas that contrast with the shiny holographic areas.
How do I achieve the best print results on holographic film?
Conduct thorough pre-press testing. Ensure proper surface tension (dyne level) for ink adhesion, use the correct ink system, optimize print pressure and dryer settings, and design artwork that leverages the holographic background.
Can the holographic pattern be embossed and printed in one pass?
On advanced in-line converting machinery, yes. The web can be first embossed to create the holographic pattern, then metallized, and subsequently printed—all in a single continuous process.
Can holographic films be laminated?
Yes, holographic films are often used as the top lamination layer to provide protection and a premium finish to printed materials. They can also be laminated onto other substrates like cardboard or plastic sheets.
What types of laminates are compatible with holographic films?
Both solvent-based and solventless laminating adhesives can be used. The choice depends on the substrate being laminated to and the required end-use properties (e.g., flexibility, clarity, heat resistance).
Can holographic films be metallized?
Yes, metallization (typically with aluminum) is a standard part of the production process for most holographic films. It creates a reflective layer that dramatically enhances the brightness and color intensity of the hologram.
What is the difference between transparent, semi-transparent, and opaque metallized holographic films?
Opaque has a full metal layer, is highly reflective, and you cannot see through it. Semi-transparent has a thinner metal layer, offering a softer sheen and allowing some visibility through the film. Transparent (without metallized) creating clear windows within the hologram.
Can holographic films be coated?
Yes, they are often coated with various functional layers, including: release coatings (for transfer films), adhesive coatings (for PSA films), protective hard coats (for scratch resistance), and primer coatings (to improve printability).
Can holographic films be corona or flame treated?
Yes, they often are. Corona treatment is a standard process to increase the surface energy (dyne level) of the film, which is crucial for ensuring good adhesion of inks, coatings, and adhesives.
Can holographic films be pouched?
Holographic films, are widely used to form stand-up pouches and other flexible packaging forms. The film provides both barrier properties and high visual impact.
What is the maximum web width of holographic film you can offer?

What is the tensile strength of holographic films?
Holographic PET film has a very high tensile strength, typically in the range of 150-220 MPa (MegaPascals). Holographic BOPP film has a lower but still good tensile strength, around 100-200 MPa in the machine direction.
What is the elongation at break of holographic films?
Holographic PET film has low elongation, usually around 100-150%, meaning it is strong but will stretch less before breaking. Holographic BOPP film has higher elongation, often 250-500%, making it more flexible and resistant to tearing.
What is the typical haze value of a holographic film?
A high-quality holographic film will have a very low haze value (<2-3%) for its non-embossed areas, meaning it is very clear. The embossed areas diffract light intentionally, which is a functional property, not haze.
What is the gloss level of holographic films?
The gloss level of the non-embossed/metallized areas can be very high (>100 GU). However, the holographic effect itself creates a perceived gloss and sparkle that far exceeds standard gloss meter measurements.
What is the oxygen transmission rate (OTR) of holographic films?
Metallized holographic films have excellent barrier properties. A standard metallized holographic PET film can have an OTR of <1 cc/m²/24hrs, and metallized BOPP can be <50 cc/m²/24hrs, protecting contents from oxidation.
What is the water vapor transmission rate (WVTR) of holographic films?
Similarly, they have very good moisture barriers. Metallized holographic PET can have a WVTR of <1 g/m²/24hrs, and metallized BOPP can be <1-2 g/m²/24hrs, keeping products dry and fresh.
Are holographic films moisture-resistant?
Yes, especially the metallized varieties. The combination of the plastic substrate and the continuous metal layer creates an excellent barrier against moisture vapor.
Are holographic films chemical-resistant?
Holographic PET films offer very good resistance to most solvents, oils, and greases. Holographic BOPP films have good resistance to water-based chemicals but can be affected by strong solvents. Always check chemical compatibility for your specific application.
What is the temperature range for storing and using holographic films?
The recommended storage and use temperature range is typically from -10°C to +50°C. Avoid extreme temperatures that could cause the film to become brittle or the layers to delaminate.
How does temperature affect the performance of holographic films?
High temperatures can soften the film, potentially deforming the embossed pattern or causing blocking (layers sticking together). Low temperatures can make the film brittle and prone to cracking.
Are holographic films dimensionally stable?
Holographic PET films have excellent dimensional stability (low shrinkage) due to their high tensile modulus and thermal resistance. Holographic BOPP films have moderate dimensional stability and can shrink slightly under high heat.
What is the shrinkage percentage of holographic films?
After 30 minutes at 150°C, holographic PET film shrinkage is very low, typically less than 1.5%. Holographic BOPP film shrinkage is higher, typically between 2-5% under the same conditions.
What is the coefficient of friction (COF) of holographic films?
COF is managed based on application. For smooth machine handling, a static COF of 0.2-0.4 is typical. This is achieved through the use of slip additives in the film's formulation.
Why is COF important for packaging machinery?
A correct, consistent COF is critical for ensuring the holographic film runs smoothly through high-speed packaging machines without slipping (too low COF) or jamming (too high COF).
What is the surface energy of holographic films?
Untreated holographic films can have a low surface energy (30-34 dynes/cm), which is insufficient for printing. After corona treatment, the surface energy should be raised to 38-42 dynes/cm or higher to ensure proper ink wetting and adhesion.
How does the base substrate (PET, BOPP, etc.) affect the film's properties?
PET offers strength, stiffness, clarity, and high heat/chemical resistance. BOPP offers flexibility, a better moisture barrier, and lower cost. The choice dictates the film's mechanical and barrier performance.
What are the optical density values for different metallization levels?
Full metallization typically has an optical density (OD) > 2.8. Semi-transparent metallization has an OD in the range of 0.2 to 0.6. Transparent/demetallized areas have an OD close to 0.
How is the brightness and diffraction efficiency of a hologram measured?
It is measured using specialized spectrophotometers and goniospectrophotometers that measure the intensity of light reflected at specific angles compared to the intensity of the incident light, providing a percentage efficiency value.
How are holographic films applied to a substrate?
The main method of application of holographic film is cold Lamination (using an adhesive)
What is holographic thermal lamination film?
It is a holographic film that has a heat-sealable adhesive already coated on it. It is applied to a substrate (like paper or card) by passing them together through a set of heated rollers (a laminator).
What is holographic wet lamination film?
It is a holographic film without a pre-applied adhesive. It is laminated to a substrate using a separate liquid adhesive (e.g., water-based, solvent-based) applied via a glue applicator roller during the process.
What is the difference between thermal and wet lamination for holographic films?
Thermal Lamination uses a pre-coated, heat-activated adhesive. Wet Lamination involves applying a liquid adhesive to the film or substrate, then pressing them together and allowing the adhesive to dry/cure.
What types of adhesives are used in holographic lamination films?
Common types include water-based acrylic adhesives, solvent-based adhesives, solventless polyurethane adhesives, and heat-activated adhesives (EVA, polyolefin).
How do I apply holographic film using a laminating machine?
For thermal film: Unroll the holographic film and the substrate, pass them together through the heated nip rollers of the laminator. For wet film: Apply adhesive to the substrate, then combine it with the holographic film and pass through pressure rollers.
What is the recommended temperature for thermal lamination holographic film?
The typical lamination temperature range is between 80°C and 120°C, depending on the specific adhesive coating and the machine speed. Consult the supplier's datasheet.
What is the recommended speed for lamination of holographic films?
Lamination speeds can vary widely from 20 meters/minute on smaller machines to over 200 meters/minute on large industrial flexo presses. It must be balanced with temperature and pressure.
How do I avoid wrinkles during holographic film lamination?
Ensure proper web tension control, use spreader rollers to eliminate any curl or wrinkles in the film, and ensure the laminating rollers are parallel and properly adjusted.
How do I avoid bubbles during hologram film lamination?
Ensure the adhesive is applied evenly, use sufficient nip pressure to force out air, and ensure the substrates are clean and dust-free. For wet lamination, ensure the adhesive has proper viscosity and drying/curing is complete.
What substrate preparation is needed before lamination of holographic film?
The substrate should be clean, dry, and dust-free. For porous substrates like paper, it may need to be sealed with a primer or a base print layer to prevent the adhesive from soaking in too much.
How do I achieve a permanent bond with holographic lamination film?
By ensuring the correct combination of temperature, pressure, and speed (for thermal), or by using the correct adhesive weight and allowing full curing time (for wet).
How do holographic films prevent counterfeiting?
They are a complex, multi-layer technology that is extremely difficult and costly to replicate accurately. They serve as a highly visible, instantly recognizable feature that consumers and inspectors can use to verify authenticity.
What is the difference between a generic and a custom security holographic film?

Do you provide technical support?
Yes, our technical team provides full support, including help with application methods, troubleshooting conversion issues, and recommending the right holographic film for your project.
Why is the holographic effect weak or dull?
Possible causes: poor quality embossing, insufficient or inconsistent metallization, using a semi-transparent metal layer where opaque was needed, or applying an overly thick ink layer that obscures the pattern.
Why is the holographic film cracking or flaking after application?
This can happen if the holographic film is too old and brittle, if it was stored in very cold conditions, or if it is being applied to a flexible substrate that bends and cracks the inflexible metallized layer.
Why is the ink not adhering to the holographic film?
The most common cause is low surface energy. The film may not have been corona treated, or the treatment has degraded over time. Using the wrong ink type is another common cause.
Why is the holographic pattern getting damaged during rewinding?
This is called "blocking" and is caused by excessive rewinding tension combined with high temperature and humidity, which causes the layers of film to stick together and tear the delicate pattern apart upon unwinding.
Why is my holographic film jamming the packaging machine?
The coefficient of friction (COF) might be too high, causing the holographic film to drag and not slide smoothly through the machine guides and rollers.
The holographic film is curling. How can I prevent this?
Curling is often due to tension issues during winding or unsymmetrical construction (e.g., moisture absorption on one side). Proper storage and using a balanced film structure can minimize curl.
Why does the holographic film have streaks or lines?
Streaks are often a result of debris or damage on the embossing shim during manufacturing, or from scratches sustained during handling or the converting process.
Why is the metallization rubbing off?
This indicates poor adhesion between the metal layer and the lacquer layer, often due to a contamination issue during manufacturing or the use of an incorrect film type for an abrasive application.
The laminated holographic film is peeling at the edges. Why?
Causes include insufficient adhesive application (wet lamination), insufficient heat/pressure (thermal lamination), substrate surface contamination (dust, oil), or using the wrong adhesive for the substrate.
The film keeps breaking on my converting machine. Why?
The film may be too brittle (old or cold), the machine tension may be set too high, or there could be sharp edges or misaligned guides on the machine causing snags.
The holographic films looks different under artificial light vs. sunlight. Why?
This is normal and expected. Holograms diffract light, so the type of light source (incandescent, fluorescent, LED, sunlight) and its angle will change the perceived color and intensity of the effect.
Do you have an in-house design team for hologram origination?
Yes, we have a skilled graphic design and engineering team that specializes in translating 2D artwork into secure, effective holographic designs.
