Problems solved by technology

[0002] Disposable paper cups are necessities of life, especially in the catering industry and are used in a huge amount, but most of the disposable paper cups currently used are non-degradable and easy to cause environmental pollution
Ordinary paper cups and paper bowls are a kind of paper container made by mechanically processing white cardboard made of chemical wood pulp and covering it with a layer of polyethylene plastic film, but polyethylene is not easy to degrade, which is not conducive to environmental protection
[0003] The Chinese patent application publication number CN105860142A discloses "an environmentally friendly, recyclable and degradable paper material and its preparation method". The paper cups are prepared through the scheme provided by it. The speed has a certain promotion effect, but the effect is not good and needs to be improved
