The recycling and reuse of PE accordion bags has formed a complete technical system from physical recycling to chemical transformation.
The square bottom design increases the stability of the bag and provides more space for the layout of the breathable structure.
Some high-end PE accordion bags have a bendable metal plate embedded in the opening, which is sealed and secured by two 180-degree folds.
These additives are typically surfactants or metal oxide particles, which can form conductive channels between PE molecular chains and reduce the surface resistance of the material.
The cooling water circulation volume must be sufficient to maintain stable cooling efficiency and prevent local overheating from causing sealing defects.
In modern daily life and commercial circulation, flat plastic bags are a common and widely used packaging medium. One of their core advantages is their extreme lightness.
