Problems solved by technology

[0004] In terms of supporting printing inks, the printing inks for heat-shrinkable films currently on the market are basically alcohol-ester-soluble inks, which will generate a large amount of VOC emissions in themselves and during use. The total VOC content of alcohol-ester-soluble inks can reach About 80%, on the one hand, it will affect the health of workers, on the other hand, it is not applicable to new environmental regulations and policies

Abstract

The invention relates to a water-based PET heat-shrinkable film plastic printing ink, which comprises the following components by weight percentage: modified polyurethane water-based polymer emulsion 15-25%, water-based polyester resin 23-30%, 95% ethanol 8-20% %, purified water 15‑25%, pigment 10‑30%, dispersant 0.5‑3%, silicone 0.1‑0.8%, oxidized polyethylene wax 0.1‑3%. The invention also provides a preparation method of the printing ink. The water-based plastic printing ink for PET heat-shrinkable film of the present invention is specially used for PET heat-shrinkable film, has the advantages of environmental protection, low VOC content, safe and non-toxic printing products, good stability and strong water resistance.

Description

technical field [0001] The invention relates to the technical field of plastic printing inks, in particular to a water-based PET heat-shrinkable film plastic printing ink using a heat-shrinkable body-fitting packaging material PET heat-shrinkable film as a printing material and a preparation method thereof. Background technique [0002] PET (polyethylene terephthalate) heat-shrinkable film is a new type of heat-shrinkable packaging material, which has the characteristics of easy recycling, non-toxic, odorless, good mechanical properties, and meets environmental protection requirements. The highest heat shrinkage rate of the film can be as high as 80%. According to the development trend of heat shrinkable skin packaging materials, PET environmental protection materials will gradually replace the PVC (polyvinyl chloride) heat shrinkable film with the largest amount in the market, and become the mainstream of environmentally friendly packaging. , is an ideal substitute for PVC ...
