In daily production activities and work life, our common plastic film can be used for daily necessities packaging, food packaging, electrical packaging, clothing packaging, etc. The convenience brought by plastic film in life has changed our way of life and improved our quality of life. But do you know the scope of plastic film testing and what are the standards for degradable plastic film testing advocated by the state in recent years? If the plastic film product has not been tested, we do not know whether it is qualified in the production process; If unqualified products appear around us, or even in contact with food, it will greatly affect people's physical and mental health.
With the development of science and technology, various functional thin film materials have been developed, and the testing of thin film materials has become one of the important ways to confirm its quality and function. As a well-known domestic packaging testing equipment manufacturer and technical service provider, Pinxiang Technology introduces plastic film testing technology and related standard knowledge.
