Advantages and disadvantages of PVC plastic sealing membrane:

1, the goods stacked on the bracket are wrapped and wrapped to make the package more stable and clean, and more super strong waterproof.

2. It has the characteristics of high tensile strength, high elongation, good self viscosity and high transparency.

3. Shrinkage film, the heat shrinkable film is extruded mainly by several different kinds of polyene resin. It has the resistance to puncture and high strength and high performance.

PVC thermal contraction membrane is insufficient:

For example, some PVC plastic film is used in summer to winter is very soft, hard; some heat shrinkable film easy to absorb dust and become opaque; also some PVC plastic film life is not long, easy to aging, not frost attacks and sun exposure, the surface is easy to crack.
