Abstract

The invention provides a transparent easy-to-tear film, and belongs to the technical field of packaging. The transparent easy-to-tear film comprises a polyethylene terephthalate (PET) layer, a CPP layer and a bonding layer, wherein the upper side of the bonding layer is bonded with the PET layer, and the lower side of the bonding layer is bonded with the CPP layer; the PET layer is formed by solidifying of first coating liquid, and the CPP layer is formed by solidifying of second coating liquid; and the first coating liquid is prepared from main components of PET, modified polyester, silver powder, titanium dioxide, an additive and an assistant, and the second coating liquid is prepared from main components of polypropylene, polystyrene, chitosan and oregano essential oil. After being bonded with a device with a seal, the thin film is good in airtightness and has the great antimicrobial ability, goods can be preserved for a long time and do not go bad, opening force of the easy-to-tearfilm meets the requirement, and the easy-to-tear film is resistant to the high temperature.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to a transparent easy-to-tear film. Background technique [0002] The easy-to-tear film is more commonly used in the field of product packaging for packaging various products, because the easy-to-tear film is easy to tear, can be torn from any position, and is moisture-proof, which is loved by consumers. However, the hardness of the easy-tear film used for packaging bags is relatively poor, and it is not convenient to be used as a sealing material for bottles and cans. [0003] PET film is a kind of packaging film with comprehensive performance. It has good transparency and luster; it has good air tightness and fragrance retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and its tensile strength and ...
