Description

A high-barrier composite packaging bag technical field

The utility model relates to the technical field of packaging bags, in particular to a high-barrier composite packaging bag.

Background technique

High-barrier films are made by extruding materials with strong gas barrier properties and polyolefins with strong heat-sealing properties and moisture-barrier properties at the same time. In addition to the non-stretching type, the film types of this material include biaxially oriented, aluminum vapor deposition, and adhesive-coated types. Among the biaxially oriented types, there are heat-resistant types for aseptic packaging products. EVOH is an ethylene/vinyl alcohol copolymer. The barrier properties of EVOH depend on the ethylene content. Generally speaking, when the ethylene content increases, the gas barrier properties decrease, but it is easy to process. The remarkable feature of EVOH is that it has excellent gas barrier properties and excellent processability. In addition, it has excellent transparency, gloss, mechanical strength, stretchability, abrasion resistance, cold resistance and surface strength. Plastic packaging bags are a kind of Using plastic as raw material, it is used in the production of packaging bags for various supplies in daily life, and is widely used in daily life and industrial production.

When the existing packaging bag is installed and used, it is easy to be worn by the hand when it is lifted, and the packaging bag has a single structure without hanging loops, which is inconvenient for hanging, which brings certain adverse effects to people's use process. Due to the lack of use of packaging bags, we propose a high-barrier composite packaging bag.
