The appearance shall not have defects such as bubbles, perforations, water lines, ribs, poor plasticization, fish-eye stiff blocks, etc. that hinder the use. The deviation of the width, length and thickness of the specification shall be within the specified deviation range. 2. Physical and mechanical properties include tensile strength and elongation at break, which reflect the ability of the product to withstand stretching during use. If this item is unqualified, the food packaging bag (film) is prone to rupture and damage during use. 3. Hygienic performance includes evaporation residue (acetic acid, ethanol, n-hexane), potassium permanganate consumption, heavy metals, decolorization test. Evaporation residue reflects the possibility of precipitating residues and heavy metals when food packaging bags encounter vinegar, wine, oil and other liquids during use. Residues and heavy metals will have adverse effects on human health. In addition, residues will directly affect the color and aroma of food., Taste and other edible quality. 4. Degradation performance According to the degradation type of the product, it can be divided into photodegradation type, biodegradation type and environmental degradation type. Degradation performance reflects the ability of the product to be accepted by the environment after being discarded. If the degradation performance is good, the bag (film) will break, differentiate and degrade by itself under the joint action of light and microorganisms, and eventually become debris, which is accepted by the natural environment. If the degradability is not good, it will not be accepted by the environment, thus forming "white pollution".
