German development of non-adhesive multilayer barrier film

German scientists recently developed a low-cost multilayer barrier film. Compared with conventional multilayer barrier films, the use of non-adhesive multilayer films significantly reduces production costs and improves product performance.

The new technology uses adhesive and structural (or barrier) resin blends as raw materials to produce a three-layer plastic film with no adhesive layer, replacing the previous five- and seven-layer films. Non-adhesive layer barrier film is mainly used in milk packaging to prolong the shelf life of milk and prevent contamination of milk.

The products used in the product were three-layer structural film (PE/1) A-PE/PE) and lining as a chemical packaging barrel. The nylon component in the PA/PE synthetic material provided good barrier properties, and the PE component provided Adhesion with outer PE.
