What are the acceptance criteria for food packaging bags?

Food packaging bags are thin film containers that come into direct contact with food and are used to contain and protect it. It greatly facilitates the preservation and storage of food in daily life, effectively reducing costs in the transportation and sales of food, and is therefore widely used in the food industry. Due to the direct contact between food packaging bags and food, the quality of food packaging bags directly affects food safety. Therefore, it is very important to choose qualified food packaging bags. So, what are the acceptance standards for food packaging bags?
1. Appearance: The appearance of food packaging bags shall not have defects that are harmful to use, such as bubbles, perforations, water marks, exposed tendons, poor plasticization, fish eye lumps, etc. At the same time, deviations in the specifications and sizes of food packaging bags need to be within the allowable production range.
2. Hygiene: The hygiene performance of food packaging bags includes evaporation residues (acetic acid, ethanol, n-hexane), potassium permanganate consumption, heavy metals, and decolorization tests. Evaporation residue reflects the possibility of food packaging bags precipitating residue and heavy metals when encountering liquids such as vinegar, alcohol, and oil during use. Residue and heavy metals can have adverse effects on human health, and in addition, residue can directly affect the quality of food such as color, aroma, and taste.
3. Degradation: The degradation performance of food packaging bags can be divided into photodegradation type, biodegradation type, and environmental degradation type according to the different degradation types of the products. Degradation performance reflects the ability of a product to be accepted by the environment after use and disposal. If the degradation performance is good, food packaging bags will break, differentiate, and degrade on their own under the combined action of light and microorganisms, becoming debris that is accepted by the natural environment.
The above compilation of acceptance standards for food packaging bags is hoped to be helpful to everyone. For more knowledge about food packaging bags, please follow the official website of Jinde Packaging. Jinde Packaging Service Hotline: 15902743510
