As is well known, there are two common types of cling film materials: PVC and PE. As a manufacturer specializing in the production line of PVC plastic wrap, how can we distinguish between these two materials? In the following content, we have introduced two methods to help everyone distinguish.

1. Testing through combustion

The combustion method is a typical way to distinguish between these two materials. This is because PVC plastic wrap has a more transparent surface than PE plastic wrap, and after ignition and combustion, it emits black smoke and does not drip oil. Unlike it, after ignition and combustion of PE cling film, there will be no strange smell and oil dripping phenomenon.

2. Distinguish through the outer packaging of the product

It can be said that this is one of the most concise and convenient methods. The identification can be achieved through the outer packaging of the cling film, and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China has requested food cling film production enterprises to clearly indicate on the outer packaging of their products.

Why is it necessary to systematically distinguish between the two materials? This is because PE cling film is a harmless material for the human body, while PVC cling film has a cancer risk. So it is necessary to distinguish between these two materials to a certain extent.
