The inspection items of food packaging bags (films) are mainly divided into five categories. The appearance must not have defects such as bubbles, perforations, water marks, explosive tendons, poor plasticization, and fish eye stiffness that hinder the use. The standard width, length, and thickness errors should all be within the regular error range.
The physical and mechanical functions include tensile strength and cracking elongation, which reflect the product's ability to withstand tension during use. If this item is not qualified, food packaging bags (films) will simply show cracking and damage during use. The hygiene functions include evaporation residue (acetic acid, ethanol, n-hexane), potassium permanganate consumption, heavy metals, and decolorization tests.
Evaporation residue reflects the possibility of food packaging bags releasing residue and heavy metals when encountering liquids such as vinegar, wine, and oil during use. Residues and heavy metals can have adverse effects on human health. In addition, residue can directly affect the color, aroma, taste, and other edible qualities of food. The degradation function can be divided into photodegradation type, biodegradation type, and environmental degradation type based on the degradation type of the product.
The degradation function reflects the ability of a product to be accepted by the environment after being discarded. If the degradation function is good, the bag (film) will crack, differentiate, and degrade on its own under the combined effect of light and microorganisms, eventually becoming debris and being accepted by the natural environment; If the biodegradability is poor, it will not be accepted by the environment, thus forming "white pollution"
