Identification method of inferior plastic tableware and packaging
To judge whether the quality of environmentally friendly plastic tableware and packaging supplies meet the product quality requirements, the following methods can be used to judge.
1: Visually inspect the appearance of the tableware: the good-quality tableware is very formal 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 blisters, 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 material, which reduces the strength of the resin. It will feel very soft to the 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, and it can be torn apart.
3: Inferior tableware can smell a pungent taste, especially after heating the tableware has a stronger taste, which is caused by excessive calcium carbonate filled in the resin. 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 the consumer's body.
Some small illegal factories that produce plastic food bags use recycled waste plastics to produce food packaging bags and containers after a simple decontamination and crushing process.
For their own health, Taizhou Wuhuan Plastic tableware manufacturers remind consumers to choose products of qualified quality when using disposable tableware
