Our extruded tubular net can be used for fruit, vegetables, bottles, eggs, roses, and so on.
The advantages as below:
1. It can be used as a material to resist erosion of chemical reagents can be used for chemical structural materials, such as various parts, pipes, corrosion resistance linings.
2. For the packaging of polyethylene film, low density film, soft and do not add plasticizers, tear resistance, high strength, non-absorbent, impervious and chemical resistance, which are necessary for packaging materials, thus poly vinyl film in the packaging industry has a very broad market and gradually replaced the celluloid.
