Buy food packaging plastics have skills

Plastic products are popular with consumers because of their light weight, durability and impact resistance. The reporter recently learned from the Beijing Municipal Quality Supervision and Inspection Station for Plastic Products that the food packaging plastic products on the market are dazzling, but the product quality is uneven. How do you purchase and use food packaging plastic products?

Look at the appearance - if the product appearance is rough, there are molding defects, color is not correct, there are impurities, the printing quality is poor, it is best not to use. The appearance of substandard products will affect the consumer's visual experience, while the appearance is a reflection of the intrinsic quality, appearance of substandard products are often of poor internal quality, affecting the use of. The unsatisfactory quality of the print will affect the appearance, while the color will fade and pollute other items.

Smell - The main reason for different smells in plastic products is the use of recycled materials and poor quality additives. The irritating odor emitted by an odoriferous product can harm the body's respiratory system. It is best not to use it.

Hands-on try - some products are very colorful in order to attract the eye of consumers. Dark pigments of poor quality can be extracted during use. These pigments are generally industrial pigments. Consumers can check by hand whether the selected dark color products are qualified: Pour a small amount of vinegar on the absorbent cotton balls, and then wipe them back and forth 100 times. If the cotton balls are dyed with color, the product is unqualified. In order to prevent pigment from penetrating into the food, it is recommended not to use deep-colored plastic products to hold oily liquid foods (except for melamine tableware).

Not greedy and inexpensive - can not simply judge the intrinsic quality of the product from the appearance, some products look very beautiful, but the use of raw materials does not meet the national health standards, the inherent quality of the product is difficult to guarantee, and the intrinsic quality can not be judged by the naked eye. China has included food packaging products in the scope of production license management. It is recommended that consumers purchase products with QS logos from regular shopping malls and supermarkets, and do not purchase products with extremely low prices.

Willing to give up - plastic products after the aging of some of the molecular chain breakage, small molecules increased, in order to avoid small molecules into the food, it is recommended that consumers do not use plastic products for too long. If you use a lot of times, or if the appearance of the product is dark, scratches, it should be replaced.
