A few days ago, Nippon Paper Co., Ltd. of Japan researched and developed a deep-stamped paper that is made of natural fiber, and whose name is “Npimold Paperâ€. Its stretchability is 5-10 times that of plain paper. The stamping paper can press texturing, patterns and three-dimensional curved surfaces when molding, similar to the processing of plastic products, and smoothing the convex image can achieve better sealing. The product can be produced by using the current plastic product equipment and molding according to the design scheme. Because it does not require heating and softening before processing, it can increase production efficiency and save energy.
Challenge Five Co., Ltd. introduced biodegradable films and envelopes produced by Mit Subishi. This film and letter are also produced from polylactic acid extracted from corn starch and can be offset using soybean ink.
Dynic Co., Ltd. develops biodegradable flexible sheet "Au Pair Corn Sheet" using cornstarch and fatty polyester as raw materials. The goal is to eventually replace PVC. This material is easy to machine and cut, easy to print, and its thickness can be adjusted according to the requirements. Landfill disposal does not pollute the environment. Because of the low calorific value during incineration, no toxic substances such as dioxins are produced, so it is less harmful to the environment.
With people's increasing concern for environmental protection and the continuous development of printing technology, printing and packaging papers have been continuously updated. Many papermaking companies in Japan have developed and produced green packaging and printing papers for the printing and packaging industry, which has stimulated the green packaging product market. .
