Suggestions on purchasing a good PVC plastic wrap

At present, there are many different types of food plastic wrap in the market. Although many people think that this kind of plastic wrap is environmentally friendly and harmless, there are still people who question whether it will be harmful to the human body after heating and other treatments. What we need to pay attention to is that we must choose carefully when purchasing plastic wrap. Here, PVC blister film manufacturers will share some relevant suggestions. 1. Look at the packaging and the logo. When buying plastic wrap, it is best to check whether there is a 'QS' mark on the product, or pay attention to its serial number and manufacturer's address. If there is a plastic wrap marked with PE, you can use it with confidence. It is not recommended to buy plastic wrap that is marked with PVC or has no material written. 2. Choose white. Although most of the plastic wrap on the market is transparent and white, it is inevitable that some of the whole rolls look yellowish in color. In this case, you should avoid buying them! 3. Observe the viscosity due to the PE film. The viscosity and transparency are poor, and it is easy to open after rubbing with hands. The PVC film contains plasticized material, which has good transparency and high viscosity. It is easy to stick to the hand after being rubbed by hand. The latter is not recommended to buy! 4. For those who are not flammable, pay attention to the fact that the real PE film has a yellow flame after ignition, and the burning speed is fast, while the PVC film is on the contrary, not only difficult to ignite, but also the root of the flame is light green and emits black smoke, and Has a pungent odor. (It is not recommended for children to perform such operations, and adults should pay attention to safety issues when operating.) I believe that the above suggestions on choosing a good plastic wrap shared by PVC blister film manufacturers will definitely be helpful to everyone.
