Also a manufacturing method of the film and its applications for the manufacture of containers.

Abstract: The invention concerns a multilayer biaxially oriented white polyester film (adhesion, absence of chalking, opacity whiteness, reflectance, hydrolysis resistance & light stability) comprising three polyester layers: a core layer and two outer layers and contains TiO2 particles. In this film: at least one layer comprises a PET whose: number average molecular weight is within [18500-40000]; intrinsic viscosity IV is ?0.70 dL/g; and carboxyl group content is ?30 eq/T. Additionally, the core layer comprises TiO2 particles in a range of [0.1-40]% w/w; the intrinsic viscosity IV is between [0.5-0.85] dL/g; a small endothermic peak temperature is between 180-230° C.; and at least one light stabilizer is added in at least one of the outer layers, in a total concentration between [0.1-35]% w/w. The invention also includes the method for manufacturing such film and the laminate which is part of the back sheet of a solar cell.

Abstract: The invention relates to a polyester film comprising, on at least one of the faces thereof, a scratch-resistant crosslinked coating. The objective of the invention is to provide a polyester film coated with an abrasion-resistant layer which adheres perfectly to the polyester substrate, and is simple and economical to manufacture. To achieve this objective, the crosslinked hard coating applied to the polyester film comprises: i. 20% to 99% by weight of at least one ester and/or one amide of (meth)acrylic acid comprising a substituted protic group; ii. 20% to 99% by weight of acrylic resin(s); iii. 1% to 40% of a polyalkylene diacrylate; iv. 0 to 50% of at least one derivative of the benzophenone family; v. 0 to 5% of at least one photoinitiator. The invention also relates to the method for obtaining this polyester film coated with an abrasion-resistant hard layer. Use in the production of polyester/metal sheet (steel) colaminate.
