Inspection standard for Food vacuum packaging bags wholesale

 2.Food vacuum packaging bags wholesale inspection items are mainly divided into four categories

(1) The appearance shall not have defects in air bubbles, perforation, water lines, violent tendons, poor plasticity, fish eye rigidity and other problems hindering the use. The deviation of specification width, length and thickness shall be within the specified deviation range.

(2) physical and mechanical properties include tensile strength and fracture elongation, which reflects the ability of the product to withstand stretching in the process of use. If this is not qualified, food packaging bags (film) are prone to rupture and damage during use.

(3)The sanitary properties of (3) include evaporation residues (acetic acid, ethanol, positive hexane), potassium permanganate consumption, heavy metals, decolourization tests. Evaporative residue is to reflect the possibility of food packaging bags to precipitate residue and heavy metal when encountering vinegar, wine, oil and other liquids in the process of use. Residual and heavy metal will have adverse effects on human health. In addition, the residue will also directly affect the food quality of the color, fragrance and taste of food.

(4) degradation performance can be divided into photodegradation, biodegradation and environmental degradation. The degradation performance reflects the ability of the product to be accepted by the environment after abandonment. If the degradation performance is good, the bag (film) will break, differentiate and degrade under the joint action of light and microorganisms, and eventually become debris, accepted by the natural environment; if the degradation will not be accepted by the environment, thus forming "white pollution".
