Because the plastic film has good air permeability and light transmission, it can also be used in agricultural production, such as the planting of vegetables, but the plastic film is not degradable, so it will cause environmental pollution, which is its fatal shortcoming, in order to solve this problem, various manufacturers are also looking for ways to improve production technology, improve product quality, Plastic film testing helps us to classify its composition
