At present, as people pay more and more attention to food safety and health issues, the standard of food plastic containers has also received more extensive attention as an important factor affecting food hygiene and safety. At present, the health and safety of food packaging materials have problems and deficiencies that cannot be overlooked.
Food container safety:
First look at the appearance of the package, check whether the product or packaging "QS" sign to see if the bottle wall is transparent, pure, generally inferior plastic products washed dirty, sticky hair astringent; try not to choose a more colorful glass, add color It may be to mask harmful impurities in recycled plastics or industrial grade raw materials.
Followed by the smell, if there is a pungent odor, even if you do not open the lid, smell from the outside, you can smell the smell; then look at the hardness, a good plastic container is thick, good hardness, hand pressure will not be inward Excessive deformation, can also be poured into the bottle of hot water, see if the bottle is deformed, there is no smell, and repeated upside down to see if sealed.
In addition, when using plastic food container, use hot water before soaking for several more soaks to remove impurities or harmful substances that the bottle may generate. When the ambient temperature is low, a small amount of hot water should be added for preheating to prevent the cups from undergoing structural changes under severe temperature changes, and the mechanical properties will be deteriorated. At low temperatures, the plastic will be brittle.
Due to the fact that China has not formulated corresponding national standards for AS raw materials used for standard materials of plastic containers, some companies have not conducted inspections and quality control on the procurement of raw materials, and AS plastic bottles made of unqualified raw materials are prone to appear as acrylonitrile monomers. Excessive standards.
