Description

High-strength blocking packaging container

Technical Field

The utility model belongs to the technical field of high-barrier packaging containers, and particularly relates to a high-strength barrier packaging container.

Background

The high-barrier packaging, i.e. the packaging material with high barrier property, is mainly pvdc, evoh, pen, nitrile resin, polyamide and the like, which are applied and developed to industrial production or have industrial production prospects. The paper plastic aluminum high-barrier package commonly used in the market at present mainly comprises 4 raw materials, namely, paper board, polyethylene, aluminum foil and printing ink. Paperboard does not directly contact the package contents, but is an important component of the package, accounting for about 75% of the total package weight. The main function is to strengthen the stiffness and hardness of the package after molding. Food-grade polyethylene in aseptic polyethylene packages accounts for about 20% of the total package by weight, and has the main effects of blocking liquid leakage and microbial attack. The weight of the aluminum foil in the aluminum foil sterile package only accounts for about 5% of the total package, and the aluminum foil sterile package has the main effects of avoiding light and blocking ventilation, keeping the content from being oxidized, reducing nutrition loss and keeping the taste fresh.

The paper plastic aluminum packaging container is light, thin, portable and single in storage, but can cause damage in the falling process when carrying articles or directly carrying, the traditional paper plastic aluminum packaging container is higher in processing cost and technical difficulty, the material is subjected to composite extrusion, the technical requirement on process materials is higher, and the adaptability to diversified application scenes is poor.
