Food plastic tray What are your inspection skills?
1. Hygienic properties include evaporation residue (acetic acid, ethanol, n-hexane), potassium permanganate consumption, heavy metals, and decolorization test. Evaporation residue reflects the possibility of separating residues and heavy metals when meeting vinegar, wine, oil and other liquids in the use of food packaging bags. Residues and heavy metals will have adverse effects on human health. In addition, residues will directly affect the food color, aroma, taste and other food quality.
2. The appearance shall be free of bad conditions such as bubbles, perforations, water lines, broken tendons, poor plasticization, etc. that may hinder the use, which will directly affect the taste of items placed on them. The degradation performance can be divided into photodegradation type, biodegradation type and environmental degradation type according to different degradation types of products. Degradation performance reflects the ability of products to be accepted by the environment after being used and discarded.
