A high clarity film having the versatility of acetate with the durability of polyester.
A strong film having good resistance to moisture, solvents, oils, etc. Usually transparent, although available with opaque ester formed by polymerization or condensation. Excellent strength, clarity and dimensional stability.
A polyester film that is silicone release coated. It provides an excellent die cutting surface and is also used on overlaminating films to provide a smooth, glass-like surface of adhesive.
A clear, glossy polyester film coated with clear acrylic adhesive. Can also be supplied with a matte surface.
A tough, stretch plastic film having very good low temperature characteristics, also used a great deal for producing semi-rigid recyclable bottles.
A compound formed by the reaction of simple molecules called monomers, having functional groups that permit their combination to proceed to high molecular weights under suitable conditions. A long-chain molecular structure.
Similar to polyethylene but stronger and having a higher temperature resistance. Various thermoplastics are polymers of propylene; excellent clarity. Also used in various thickness in the printing of labels as well as backing or liner materials.
A thermoplastic produced by the polymerization of styrene. The electrical insulating properties are outstanding and the material is relatively unaffected by moisture.
Refers to a group of resins formed by polymerizing various vinyl monomers.
Usually a very thin transparent film with excellent resistance to acids, water and organic solvents. Saran.
