The quality of a food packaging bag
can directly affect the product, and it accompanies the whole process of food production, circulation and use. So how to judge whether the food packaging bag is qualified? 1. The appearance of the food packaging bag shall not have any defects such as air bubbles, perforations, water marks, violent tendons, poor plasticization, and fish-eye stiffness that are hindering the use. Specification width, length, thickness deviation should be within the specified deviation range. 2. In the process of making food packaging bags
, the 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. 3. Hygienic performance includes evaporation residue (acetic acid, ethanol, n-hexane), consumption of potassium permanganate, heavy metal, and decolorization test. Evaporation residues reflect the possibility of residues and heavy metals being precipitated 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 food quality. Therefore, companies that customize food packaging bags must conduct on-site inspections of manufacturers to ensure safety and hygiene before placing orders. 4. Degradation performance According to the different types of product degradation, it can be divided into photodegradable type, biodegradable type and environmental degradation type. The degradation performance reflects the ability of the product to be accepted by the environment after being used and discarded. If the degradation performance is good, the bag (film) will break, differentiate and degrade by itself under the combined action of light and microorganisms, and eventually become debris, which is a natural environment. Acceptable; if the degradability is not good, it will not be accepted by the environment, thus forming“White pollution”.
