3. Biodegradability test: the degradation types of products can be divided into photodegradation, biodegradation and environmental degradation. If the degradation performance is good, the bag will break, differentiate and degrade by itself under the joint action of light and microorganisms, and finally become debris, which is accepted by the natural environment to avoid white pollution.
4. Appearance inspection: The appearance of the food packaging bag shall be flat without scratches, scalds, bubbles, oil breaks and wrinkles, and the heat seal shall be flat without false sealing. The film shall be free of cracks, pores and separation of composite layers. No contamination such as impurities, foreign matters and oil stains.
5. Specification inspection: the deviation of its specification, width, length and thickness shall be within the specified range.
6. Physical and mechanical property inspection: the quality of the bag is better. Physical and mechanical properties include tensile strength and elongation at break. It reflects the stretching ability of the product during use. If the stretching ability of the product is poor, it will be easy to crack and damage during use.
