How to distinguish whether paper bowls are environmentally friendly materials or unqualified products?

To distinguish whether paper bowls are environmentally friendly materials or unqualified products, the following aspects can be considered:

View identification and standards:

Check if there is complete identification information on the paper bowl packaging, including production license number and QS identification.

Pay special attention to whether it indicates compliance with relevant national standards such as GB/T 27591, which is an important basis for determining whether the paper bowl is qualified.

Observe appearance and material:

The color of the paper bowl should not be too bright, and excessive use of chemical dyes should be avoided.

Check the paper bowl in front of the light to ensure that there are no impurities and that there is no blue color under the fluorescent lamp, in order to eliminate the risk of excessive fluorescent agents.

Verify physical properties:

Gently squeeze the sides of the paper bowl with your hand. High quality paper bowls should be harder and have resilience, and not easily deformed.

High quality paper bowls usually have good compressive strength and leakage performance, and can be tested for durability by filling them with water.

Smell the odor:

Smell if there is a pungent odor in the paper bowl, especially the smell of ink or mold, which may be a sign of unqualified products.

Understanding production materials:

Environmentally friendly paper bowls are usually made from renewable materials such as wood, bamboo, straw, etc., and the production process pays attention to the application of environmental protection technologies.

Inquire or inquire about the raw material sources and production processes of paper bowls to understand their environmental friendliness.

In summary, based on the comprehensive judgment of the above aspects, it is possible to accurately distinguish whether paper bowls are environmentally friendly materials or unqualified products.
