The main unqualified agricultural film project is thickness and deviation. The measured thickness and deviation of unqualified products are inconsistent with the requirements of the standard. For example, the sales volume of Shanghai Zhizhiyuan Plant Protection Technology Co., Ltd. No. 55 Branch Company is designated by Linyi City, Shandong Province. Mountain Yintong Plastic Products Factory Production (or Availability) 'Graphic Trademark' Brand Polyethylene Black Film (Model Specification: 1000×0.008mm), Thickness Limit Deviation Measured as +0.020mm (Standard Value: ±0.003mm), Average Thickness The deviation is +131% (the standard value should be ±15%), all far beyond the standard requirements. The black plastic film has low light transmittance, which can effectively prevent the evaporation of soil moisture and inhibit the growth of weeds. The use of an inappropriate thickness of the plastic film is not conducive to Crops grow. Excessive thick film can cause the ground temperature to be too low and the crops grow slowly.
