Problems solved by technology

[0003] Existing materials used to make card bases such as polyvinyl chloride, acrylonitrile-butadiene-styrene, copolyester and modified copolyester, etc., have certain deficiencies in some aspects due to their own performance, such as polyvinyl chloride Vinyl chloride has poor environmental protection, low temperature resistance, and produces toxic substances after decomposition; acrylonitrile-butadiene-styrene is easy to age, fade and become brittle, and has poor weather resistance; copolyester is prone to warping, poor printability and adhesion , the surface needs to be pretreated and coated with adhesive to meet the requirements of use; although the modified copolyester has good overall performance, it still has the problem of low temperature resistance, which also limits its application.
