Mono-material PEF shrink film is a polyolefin heat shrinkable film produced by double bubble technology and downward water-cooled blown process. It is made of a single polyethylene material and can be recycled.

PEF film has the advantages of excellent light transmission, soft corners, good sealing, high shrinkage rate, and low shrinkage temperature. It has excellent packaging effect and can be used in high-end product packaging. It is suitable for use on automatic and semi-automatic packaging machinery.

The PEF film has passed the EU Recyclable Certification, China Double E Certification, and was certified by TÜV Rheinland of Germany. It is recyclable, scientific and environmentally friendly, and reduces environmental pollution. Compared with traditional POF and cross-linked films, PEF has many advantages, brings huge value and attraction to the market, complies with the development trend of recyclability in the global packaging field, and complies with the internationally advocated ecologically sustainable development strategy.

Compared with the POF film and cross-linked film commonly used in the market, the high-end environmentally friendly PEF film launched by our company, structurally, PEF meets the single polyethylene material standard and can be produced by double bubble technology and downward water-cooled blown process without physical cross-linking. This is a major technological breakthrough for heat shrinkable film in the industry! Films with conventional composite structures are not conducive to recycling because it is difficult to peel off multiple layers of different materials. Compared with multi-layer composite materials, single-material PEF films do not require material separation, and while meeting the requirements of packaging barrier performance, they also increase the recyclability of packaging.
