BOPP Film Manufacturing and Recycling

Time:2022-05-09

In 1905, humans first synthesized “plastics”, and in 1907, they applied for the first patent for phenolic plastics. Plastics have become an integral part of our lives.

Plastic film is more versatile, widely used in the cover packaging of bread, clothes, shoes and socks, cigarettes, books, and as daily sealing tape after applying self-adhesive. The production of BOPP film is to first pass the melt of high molecular polypropylene into a sheet or thick film through a long and narrow head, and then in a special stretching machine, simultaneously or step by step in two vertical directions (longitudinal, transverse) It is stretched and made by appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).

Online Granulation Recycling Process:

In the production of BOPP film, there will be unqualified products that are screened out due to size/thickness and other reasons. This part of BOPP film can be re-entered into the production line in the form of online recycling and granulation through online granulation, which greatly benefits customers. Saves cost and material waste, recovers losses and adds new profit growth points.

After long-term research and exploration on the BOPP film recycling granulation machine, Purui Machinery has realized an integrated high-efficiency online granulation recycling machine of crushing-extrusion-cutting.

At present, there are more than 60 ML series high-efficiency production lines at home and abroad specializing in the online recycling and granulation of BOPP/CPP/BOPA/BOPET, and the third-generation products have been developed, which has the ability to compete with the world’s first-class equipment.
