Identification method of inferior plastic tableware and packaging


  Judging whether the quality of environmentally friendly plastic tableware and packaging supplies meets product quality requirements can be mainly judged by the following methods.

  1: Visually inspect the appearance of the tableware: the good-quality tableware is very regular in appearance, with clear edges and lines, and the product has a smooth finish inside and outside. The four corners of the box have uniform thickness, no sand holes, the whole edge of the box is cut flat, and the buckle should be easy to open and close. Unqualified or fake environmentally friendly plastic tableware does not meet the above conditions.

  2: Hand touch: Good quality tableware feels smooth, with strong toughness and elasticity. Inferior tableware is added with a large amount of filling materials, which reduces the strength of the resin. It will feel very soft when touched by hand, and the inner layer will feel like fine sandpaper. If you tear it by hand, it will be as easy as tearing kraft paper.

  3: Inferior tableware can smell a pungent taste, especially after heating the tableware, the taste is even greater, because the resin is filled with excessive calcium carbonate. Calcium carbonate must undergo surface activation treatment with coupling agents, dispersants, lubricants and other materials before it is made into particles. If the content of calcium carbonate in the resin is too much, it will cause peculiar smell. Moreover, certain substances will remain in the product and will be released after a higher temperature to cause harm to consumers' health.
