The rapid growth of the solar (photovoltaic, PV) industry is driving demand for advanced packaging materials for solar modules. This has led to the development of new materials, notably EPE film.

Oxygen transmission rate is a crucial indicator for evaluating the barrier properties of packaging materials. For food packaging, excellent oxygen barrier performance is essential to ensure food safety and effectively extend shelf life.

ASTM D3985 is a standard developed by the American Society for Testing and Materials (ASTM), specifically designed for determining the oxygen transmission rate (OTR) of plastic film and sheeting.

In food industry, the overall migration is measured to ensure food safety, to assess the inertness of the material, and to comply with regulations.
