BOPP/BOPET/Aluminized BOPET Laser Film: Preferred for High-Value Anti-Counterfeiting Packaging

Under the trend of consumption upgrading, packaging is not only a protective carrier but also a key to brand image transmission and anti-counterfeiting traceability. Our laser films offer three substrate options (BOPP, BOPET, aluminized BOPET), with unique textures formed on the film surface through holographic laser technology, meeting both visual appeal and practical performance to adapt to packaging needs of different industries.​

● BOPP Laser Film: Based on biaxially oriented polypropylene, it is lightweight (thickness 18-30μm) with strong flexibility and excellent low-temperature resistance (no brittleness at -20℃), suitable for flexible food packaging (e.g., cookie bags, snack bags). Its laser texture is clear, with bright colors after printing, and relatively low cost, making it a cost-effective choice for mass consumer product packaging.​

● BOPET Laser Film: Made of biaxially oriented polyethylene terephthalate, it has high stiffness and high-temperature resistance (short-term tolerance at 120℃), not easy to deform, suitable for rigid packaging (e.g., skincare boxes, gift box outer films). The laser pattern on the film surface has a strong three-dimensional effect, and its scratch resistance is better than that of BOPP version, with no easy wear after long-term use, maintaining the high-end texture of the packaging.​

● Aluminized BOPET Laser Film: Vacuum aluminized (aluminum layer thickness 30-50nm) on the BOPET substrate surface, it combines laser anti-counterfeiting and high barrier properties—light shielding rate over 99%, effectively blocking oxygen and water vapor to delay food oxidation and deterioration (e.g., chocolate, nut packaging); at the same time, the combination of aluminum layer and laser texture forms a unique metallic luster with stronger anti-counterfeiting effect, suitable for scenarios with strict anti-counterfeiting requirements such as tobacco, alcohol, and high-end electronic products.​

Holographic embossing technology is used to create laser textures, pressing light columns, dots, dynamic holograms and other patterns on the film surface through high-precision molds. These textures cannot be replicated by ordinary printing, with natural anti-counterfeiting properties. For example, after being used in tobacco and alcohol packaging, consumers can distinguish authenticity by observing the three-dimensional sense and light change effect of the laser pattern; at the same time, the glossiness of the laser film reaches 85%-95%, far exceeding that of ordinary films (60%-70%), presenting a bright visual effect under light, which can instantly enhance the high-end sense of product packaging and help brands stand out on the shelf.​

All three substrate laser films have passed strict physical performance tests: wear resistance (no obvious scratches after 50 rubs with 500g load), folding resistance (no cracks after 20 repeated 180° folds), ensuring the packaging remains intact during transportation and storage; BOPET and aluminized BOPET versions also have good chemical resistance, with no swelling or odor when in contact with skincare products and food additives, complying with FDA and EU 10/2011 food contact standards. In addition, the film is compatible with multiple printing processes such as flexography and gravure, with ink adhesion reaching level 4B. After overlapping printed patterns with laser textures, it can present richer visual layers, meeting the personalized packaging needs of brands.​

In the food industry, BOPP laser film is used for cookie and candy packaging, improving aesthetics while ensuring food freshness; in the daily chemical industry, BOPET laser film is used for skincare gift boxes, with high stiffness and no easy deformation, highlighting the brand's high-end positioning; in the anti-counterfeiting field, aluminized BOPET laser film is used for tobacco, alcohol, and electronic product labels, combining the light shielding property of the aluminum layer and the uniqueness of laser to build a dual anti-counterfeiting barrier, effectively curbing the circulation of counterfeit products and safeguarding brand reputation.
