Check the labels: For plastic tableware, look for the "No. 5 PP" symbol and the food-contact safety mark (GB 4806.7-2016); for paper tableware, check for compliance with the GB 4806.8-2016 standard. Adherence to standards ensures reliability.
Smell for odors: If the item has a pungent or strong plastic smell, do not use it; it is likely an inferior product.
Examine the appearance: The surface should be smooth, free of impurities, and show no signs of deformation or damage. Exercise caution with items that are overly brightly colored (especially those with colored inner surfaces), as they may pose risks associated with additives.
