Abstract

The invention discloses an eco-friendly non-toxic food color printing packaging film and a preparation method thereof. The eco-friendly non-toxic food color printing packaging film comprises, by weight, 10 to 20 portions of cochineal, 15 to 20 portions of red yeast rice powder, 6 to 12 portions of ethyl acetate, 5 to 8 portions of ethanol, 5 to 7 portions of beeswax, 10 to 15 portions of curcumin, 2 to 8 portions of xanthan gum, 15 to 20 portions of titanium dioxide, 5 to 8 portions of carrageenan, 11 to 17 portions of starch, 5 to 10 portions of natural rubber and 20 to 30 portions of polylactic acid. The eco-friendly non-toxic food color printing packaging film has high strength and can be reused many times so that wastes are reduced and environmental damage is reduced. The preparation method has the advantages of simple processes, operation easiness and low production cost.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to an environmentally friendly and non-toxic food color printing packaging film and a preparation method thereof. Background technique [0002] Plastic bags have indeed brought convenience to our lives, but the convenience at this moment has brought long-term harm. The recycling value of plastic bags is low. In addition to causing "white pollution" during use, it also has potential hazards. The plastic structure is stable, it is not easy to be degraded by natural microorganisms, and it will not separate for a long time in the natural environment. This means that if waste plastic waste is not recycled, it will become pollutants in the environment and accumulate forever, which will cause great harm to the environment. As the concept of environmental protection is deeply rooted in the hearts of the people, more and more people continue to explore plastic bags with degradable and env...
