Abstract

The invention discloses a preparation method of a cutting preventive APET (amorphous polyethylene terephthalate) composite membrane. The preparation method comprises the following steps: (a), material selection, (b), adhesive application and compositing; (c), ultraviolet curing: and (d), aftertreatment of the composite membrane. The preparation method of the cutting preventive APET composite membrane is reasonable in process arrangement, scientific in implementation process and moderate in cost; and the prepared composite membrane has stable performance, especially unique cutting preventive capacity, various accidental conditions can be dealt with, and packaged goods are transported and stored more safely and reliably.

Description

technical field [0001] The invention relates to a preparation method of an APET composite film, in particular to a preparation method of an APET composite film with anti-cut ability, and belongs to the technical field of APET products. Background technique [0002] APET film is a polyester sheet of plastic-absorbing material, also known as polyester hard tape. It belongs to thermoplastic environmental protection plastic products. Its side materials and waste products can be recycled. Degradable plastic. When packaged products made of this material are discarded, they end up as water and carbon dioxide. APET environmental protection film is widely used in the packaging of cosmetics, food, electronics, toys, printing and other industries, such as various high-end blister packaging, folding boxes, rubber tubes, windows, etc. At this stage, China already has relatively mature APET production technology, and its price is much lower than that of PETG sheet. [0003] APET film h...
