The food packaging bag belongs to a kind of outer packaging design. This kind of bag is often used in our daily life. In order to preserve food more conveniently and keep the freshness of food, this kind of packaging bag came into being. It can directly contact with food without affecting the quality of food.
1. Hygienic inspection: in the flexible packaging, its hygiene is very important, because it directly contacts with the food we eat daily, so the primary standard of its inspection is hygiene.
2. Safety inspection: The raw materials and additives used in the bag shall comply with the relevant national quality requirements, and shall not cause poisoning and other injuries to the human body.
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.
