When purchasing, pay attention to the following points:
1. Check the sealing performance. Generally, food boxes should be sealed in plastic packaging bags, which should not be damaged. Food boxes with loose packaging are prone to environmental pollution and hygiene cannot be guaranteed.
2. Look at the outer packaging. Be sure to carefully check if the packaging label indicates the contents that must be marked according to national regulations, such as "product name, manufacturer's name, address, product execution standard, production date, shelf life, and hygiene license". If the label content is incomplete or not standardized, such food boxes should not be purchased.
3. Look at the box body. A high-quality food box should have a uniform color and clear outline on the body, and there should be no obvious dents or wrinkles at the mouth of the box.
4. Look at the box mouth. Pay attention to the flatness and smoothness of the box mouth, without any waste edges or burrs. The cup body should be clean and transparent, with uniform thickness and no impurities, bubbles, water marks, or fish eye blockages.
5. Look at the hardness. To choose a food box with a better body hardness, try to choose a food box with a thick and stiff wall. When selecting a food box, you can gently squeeze the sides of the box with your hand to roughly determine the hardness of the box body.
