Embodiment 1
[0034] A light weight anti-shrinkage biaxially stretched polyester film, said film is an ABA type three-layer co-extrusion film, wherein surface layer (A) 1 is a functional layer, and core layer (B) 2 is a transparent layer or a colored layer;
[0035] The surface layer (A) 1 accounts for 15% to 25% of the total weight of the lightweight anti-shrinkage biaxially stretched polyester film, and the surface layer (A) 1 includes optical Grade polyester particles, 10%-20% polyester chips, 0%-10% anti-shrinkage agent, 20%-60% poly-1,4-cyclohexanedimethylene terephthalate plastic particles;
[0036] The core layer (B) 2 accounts for 75% to 85% of the total weight of the lightweight anti-shrinkage biaxially stretched polyester film, and the core layer (B) 2 includes 25% to 65% of the weight of the core layer (B) 2 % of optical-grade polyester particles, 30% to 70% of poly-1,4-cyclohexanedimethylene terephthalate plastic particles, and 0% to 5% of masterbatch particles.
