Abstract

The invention discloses a polyester film, and a preparation method and applications thereof. The polyester film is prepared by adopting processes of casting and setting and comprises the following components according to the weight ratio: 300-1200ppm of antiblocking inorganic additive and the balance polyethylene glycol terephthalate or modified resin with the intrinsic viscosity being more than 0.78dL / g. In the invention, the defects in the prior art are overcome, and the advantages of low degree of orientation, high elongation at break (up to 480%), good toughness for long time, large molecular weight and narrow distribution are realized. The polyester film has the characteristics of good adhesiveness on metal, low lining temperature, good deep-punching processing resistance, excellent printing effect, low small-molecular mobility and the like and has wide use prospect in the industries such as metal package and flexible package.

Description

technical field

[0001] The invention relates to material technology, in particular to a polyester film, its preparation method and application. Background technique

[0002] With the continuous development of the metal packaging industry and the continuous improvement of the can-making process, the demand for packaging materials has become increasingly prominent. In recent years, many famous companies at home and abroad have successively developed products related to coated iron. Due to its excellent barrier properties, excellent lamination and printing performance, and good processability, polyester film has become the best choice for coating in coated iron. The common types of coated iron are double-drawn modified polyester film, glue-coated double-drawn polyester film, heat-sealed double-drawn polyester film, etc. Coated iron is gradually replacing painted iron to apply the policies and regulations of various countries on environmental protection, energy saving and sanit...
