How do we purchase food plastic packaging bottles? Plastic products are loved by consumers for their light weight, durability and impact resistance. There are many types of plastic products used for food packaging on the market, but the quality of the products varies. How to choose and use food packaging plastic products?
Look at the appearance - if the product has a rough appearance, molding defects, incorrect color, impurities, or poor printing quality, it is best not to use it. Products with substandard appearance quality will affect consumers' visual experience. At the same time, appearance is also a reflection of inner quality. Products with substandard appearance often have poor internal quality, which affects their use. If the printing quality is not up to standard, it will affect the appearance. In severe cases, it will fade and contaminate other items.
Odor – The main cause of odor in plastic products is the use of recycled materials and low-quality additives. The pungent odor emitted by products with peculiar smell can harm the human respiratory system, so it is best not to use them.
Try it out - some products come in very bright colors to catch the consumer's eye. Inferior dark-colored products will stain during use. These pigments are generally industrial pigments. Consumers can check whether the selected dark-colored products are qualified by themselves: pour a little vinegar on an absorbent cotton ball, and then wipe it back and forth 100 times in contact with the food surface. If the absorbent cotton ball is stained, the product is unacceptable. To prevent pigments from penetrating into food, it is recommended not to use dark plastic products to hold oily liquid food (except melamine tableware).
Don't be cheap – you can't judge a product's intrinsic quality simply by its appearance. Some products are very beautiful in appearance, but the raw materials used do not meet national health standards. my country has included food packaging products in the scope of production license management. It is recommended that consumers go to regular shopping malls and supermarkets to buy products with the QS logo and not buy products with extremely low prices.
After plastic products age, some molecular chains break and small molecular substances increase, making them reluctant to give up. In order to prevent small molecular substances from entering food, consumers are advised not to use plastic products for too long. If you have used it too much, or if the product appears dull and scratched, it should be replaced.
