How does optical grade pressure sensitive adhesive improve the adhesion performance of holographic laser film?
In the field of self-adhesive holographic laser films, the adhesion performance of optical-grade pressure-sensitive adhesives directly affects the anti-counterfeiting effect, durability and user experience of the product. With 30 years of experience in adhesive material research and development, Baozhongbao provides customers with high-performance and high-reliability bonding solutions, helping global brands achieve safer and more colorful packaging and decoration applications.
(1) High transparency to ensure that the holographic optical effect is not affected
Ordinary adhesives may affect the clarity of the holographic pattern due to refractive index mismatch or haze problems.
Baozhongbao Company's optical grade PSA adopts **low yellowing, high light transmittance (>90%)** formula to make the laser holographic effect more vivid and three-dimensional.
(2) Precise adhesion control to adapt to different substrates
Holographic films may be attached to different material surfaces such as PET, BOPP, PVC, metal or glass.
Baozhongbao Company uses acrylic copolymerization modification technology to provide **initial adhesion (Tack), holding power (Holding Power), peeling force (Peel Adhesion)** precise balance to avoid debonding or residual glue.
(3) Weather resistance and chemical stability
Holographic films may be used for outdoor packaging or high humidity environments. Ordinary adhesives are prone to aging and yellowing.
Baozhongbao Company's optical adhesive uses UV stabilizer + antioxidant formula to ensure long-term stable bonding in an environment of -20℃~80℃.
(4) Traceless removal and environmental safety
Some applications (such as decorative films for electronic products) require no residual adhesive when they need to be replaced.
Baozhongbao Company provides removable PSA that complies with RoHS/REACH standards and is suitable for high-end scenarios such as food and pharmaceutical packaging.
Baozhongbao Company's optical-grade pressure sensitive adhesive (PSA) is specially designed for holographic laser film, ensuring high transparency, strong adhesion and durability, and is widely used in anti-counterfeiting packaging, label printing, electronic product decoration and other fields.
