1. What is the basic function of laminating film?
Laminating film is a transparent, heat-pressed film, commonly made of BOPP+EVA or PET+EVA. After being heated in a heat laminator, the EVA adhesive layer in the film melts and firmly bonds to the paper surface, forming a protective layer.
2. Why do documents need laminating?
1.) Waterproof and stain-resistant
Even if coffee is spilled or rain gets wet, laminating a document will leave virtually no marks after wiping. This is particularly suitable for important documents such as outdoor construction drawings, menus, labels, and household registration books.
2.) Abrasion-resistant
Documents that are frequently handled are prone to edge damage and fuzzing. Using laminating film of an appropriate thickness (such as 25μm or 32μm) can effectively prevent these problems and maintain crisp edges.
3.) Anti-fading and Anti-fingerprint
Laminating film has a certain degree of UV resistance, which can slow down the fading of paper. It is particularly suitable for long-term preservation of documents such as awards, certificates, display boards, and photos.
3. What are the common applications of laminating film?
Education: Courseware, student ID cards, campus notices
Office: Company policy announcements, access passes, reports
Catering: Menus, price lists, oil-proof labels
Medical: Registration forms, laboratory test reports, medical records
Government documents: Household registration books, ID card copies, receipts
Souvenirs: Photos, awards, collectible documents
4.Why do professional buyers prefer industrial-grade laminating film?
For organizations requiring high-volume laminating (such as printing plants, government departments, and educational institutions), the quality and performance of laminating film are crucial:
High-transparency film layer: Provides clear images and text, enhancing visual quality.
High-viscosity hot-melt adhesive layer: Utilizes an EVA + LDPE blend to prevent debonding and bubbling.
Eco-friendly formula: Compliant with EU environmental regulations such as RoHS and REACH, safe and odorless.
Multiple specifications available: Standard thicknesses range from 18μm to 43μm, meeting varying protection requirements.
High-speed compatibility: Compatible with all heat sealers, ensuring film retention and continuity.
