Document Type and Number:
WIPO Patent Application WO/2023/004971
Kind Code:
A1
Abstract:
An ultralow-temperature heat-seal wear-resistant BOPP thin film, comprising an upper-layer structure, a middle-layer structure and a lower-layer structure which are arranged in sequence. The raw materials for forming the upper-layer structure comprise: a first low-temperature heat-seal metallocene, a first polydimethylsiloxane, a silicone masterbatch, a first anti-blocking agent, and a first copolymer. The raw materials for forming the middle-layer structure comprise: homo-polypropylene, petroleum resin and an antistatic agent.
