the technology of BOPET (Biaxially Oriented Polyester) film products takes the lead in adopting continuous polymerization and direct casting film technology that is international initiation, and overcomes the problems such as large discrepancy between batches of chip casting that exists commonly at present and influence stability of inner quality of BOPET film, thus it makes ABA compound high transparent BOPET film product, which are produced by us more excellent quality, more stable production and much lower consumption.
