- Dec 28, 2018 -

At present, the plastic wrap on the market is mostly PVC and PE. In comparison, the transparency, stretch and viscosity of PVC cling film are stronger than PE. Identify which food safe plastic wrap is a material that can be touched or fired by hand. PE cling film has poor viscosity and transparency, and is easy to spread after rubbing with hands, and will break after stretching.

 

The PVC cling film has excellent viscosity and transparency, and it does not break even if it is stretched and stretched. When the PVC cling film is burnt, the flame is black, with black sputum, accompanied by a pungent smell, and does not drip. It will automatically go out after leaving the fire source. The PE material's food safe plastic wrap burns yellow when burned, tastes odorless, drops oil, and can continue to burn after leaving the fire source. The cling film of PVC material is yellowish, and the cling film of PE material is white.

 

In the process of producing PE material food safe plastic wrap, it is not necessary to add any plasticizer, so it is very safe to use. Regardless of the type of plastic wrap, we should use it in accordance with the temperature range specified on the product packaging. Generally, wrap film should be used in the temperature range of -40 ° C ~ 120 ° C.
