Tips On Quality Identification Of Disposable Packaging Boxes

1. Color
Most people think that white lunch boxes are clean and hygienic, but this is not the case with biodegradable lunch boxes. Generally, biodegradable lunch boxes use paper or plants as raw materials, and their color is not white. The paper we use daily has also been bleached. For example, lunch boxes made of starch will be gray, and other lunch boxes are also slightly darker in color, not pure white. Some qualified lunch boxes may also add edible additives in the post-production process to enhance their aesthetics.
2. Smell
Some inferior lunch boxes themselves will have a certain pungent smell, which is due to the addition of some harmful chemical reagents or industrial additives during the processing.
3. Texture
A qualified lunch box itself will have a certain degree of "toughness" and will not be brittle or break when poked. It should have high strength.
