Abstract

The invention discloses an environmentally-friendly degradable paper cup material and a preparation method thereof. The preparation method comprises that a base paper is prepared from peanut hulls, sugar cane peel, garlic peel, onion peel, honeysuckle, houttuynia and isatis root through crushing, beating and paper making and polylactic acid as laminating slurry is applied to the base paper so thatan environmentally-friendly degradable paper cup with good performances is obtained. The raw materials are low in cost, environmentally-friendly and nontoxic. The preparation method promotes resourcerecovery and recycling, changes wastes into valuables, has no pollution on the environment and promotes the sustainable development of the environment. The used Chinese herbal ingredients are fully used and provide broad spectrum antibacterial effects.

Description

technical field [0001] The invention belongs to the technical field of paper cups, and in particular relates to an environment-friendly degradable paper cup material and a preparation method thereof. Background technique [0002] Disposable paper cups are an indispensable product in people's daily life, especially in the catering industry, where the usage of disposable paper cups is very large, but many disposable paper cups currently used are non-degradable and easy to cause environmental pollution. With the modern society's higher and higher requirements for the living environment, people pay more and more attention to the cleanliness and greening of the environment. The development of disposable degradable paper cups is an effective way to solve plastic pollution. [0003] At present, ordinary paper cups are a kind of paper container made by mechanically processing base paper (white cardboard) made of chemical wood pulp and covering a layer of polyethylene plastic film. A...
