1.PVC shrink film 

By adding other components to the PVC shrink film, its temperature resistance, toughness and extensibility can be enhanced. The top layer of this surface film is paint, the main component in the middle is PVC, and the bottom layer is the adhesive for the back coating. This is a composite material that is very popular and widely used in today's world. PVC is the best material for producing 3D masks.

2. POF shrink film 

POF It is a multi-layer co-extruded environmentally friendly polyolefin heat shrinkable packaging material. The main components of POF shrink film are PE and PP. Unlike PVC, POF is a flexible and environmentally friendly shrink film that does not release harmful gases during combustion and can also come into contact with food. POF shrink film is formed by extrusion of double-layer PE or PP films, giving it various characteristics such as softness, strength, high transparency, and high shrinkage rate. It is an environmentally friendly heat shrinkable packaging material and has been widely promoted and applied in the current international market, and is recognized in the European and American markets.

3. OPS shrink film 

OPS (Directional Polyethylene) OPS heat shrink film is a new type of shrink-wrap packaging material that meets environmental protection requirements. It features high strength, large rigidity, stable shape, good gloss, and excellent transparency. The processing is convenient, easy to color, has good printing performance, and high printing resolution. For those constantly seeking exquisite printed trademarks, this is a complete material advancement. Due to the high shrinkage rate and strength of the OPS film, it can closely adhere to various shaped containers. It not only can print exquisite patterns but also can meet the application requirements of various shaped and novel packaging materials.

4. PET heat shrink film 

PET heat shrink film is a new type of heat shrink packaging material. Due to its convenient recycling, non-toxicity, lack of odor and excellent mechanical properties, 

In particular, due to its advantages such as environmental friendliness, polyester (PET) has become the best alternative to polyvinyl chloride (PVC) heat shrink film in developed countries.
