PVC film (polyvinyl chloride film) is a multifunctional plastic material made primarily of polyvinyl chloride, with the addition of plasticizers, stabilizers, colorants, and other additives.
Good Physical Properties
Wear-resistant, scratch-resistant, water-resistant, oil-resistant
High transparency (light transmittance can reach above 91%)
Certain flexibility (soft type) or rigidity (hard type)
Chemical Stability:
Resistant to acids and alkalis, corrosion-resistant (except strong oxidizing acids like concentrated sulfuric acid and concentrated nitric acid)
Resistant to grease and oxidation
Processing and Forming Advantages:
Can be produced in various thicknesses (usually 0.08–0.2mm) through processes such as calendaring, blow molding, or cast film
Easy to print, laminate, and heat seal (especially suitable for hard PVC)
Hard PVC is non-toxic and pollution-free, with a long shelf life; soft PVC contains plasticizers, which may leach out during long-term use, limiting food contact
Functional Extensions:
Can be made into adhesive films for the card industry (such as IC cards and membership cards)
Can be made into anti-static films that rely on electrostatic adsorption, leaving no adhesive residue, suitable for protecting glass and electronic product surfaces
Can be made into stretch wrap films for industrial packaging with self-adhesive properties
Can serve as agricultural greenhouse films, providing good thermal insulation and light transmission
Can be used as heat shrink films, with high transparency and significant shrinkage, suitable for labels and outer packaging
