Manufacturing process of fresh-keeping, antibacterial and fully-degradable packaging bag or packaging box

Abstract

The invention relates to a manufacturing process of a fresh-keeping, antibacterial and fully-degradable packaging bag or packaging box, the fresh-keeping rate of the packaging bag or packaging box produced by the manufacturing process can still reach 99.8% or more after 24 hours, the antibacterial rate of the packaging bag or packaging box can also reach 99.8% or more after 24 hours, and the packaging bag or packaging box is filled with water and oil respectively, so that the packaging bag or packaging box can be fully degraded. Watermarks or oil marks do not appear on the surface of the packaging bag or the packaging box within 72 hours, that is, the packaging bag or the packaging box produced by adopting the manufacturing process has excellent fresh-keeping performance, excellent antibacterial performance, excellent waterproof performance, excellent oil-proof performance and excellent degradation performance; the problems that an existing packaging bag or packaging box does not have the functions of preservation and bacteriostasis are effectively solved, and the problem that an existing packaging bag or packaging box manufactured through a film covering technology is poor in waterproof effect and poor in oil-proof effect is solved.

Description

technical field [0001] The invention relates to a process for making a fresh-keeping, antibacterial and fully degradable packaging bag or packaging box. Background technique [0002] The traditional production of packaging bags or packaging boxes is generally made of paper or plastic materials. Due to the factors such as difficult degradation and environmental protection of packaging bags or packaging boxes made of plastic materials, they are gradually eliminated and used. Although the paper packaging bags or packaging boxes produced by the lamination process are more environmentally friendly and degradable than the packaging bags or packaging boxes made of plastic materials, they are not waterproof, oil-proof, easy to deform, easy to rot and degrade. Long time and other shortcomings, and whether it is a packaging bag or packaging box made of paper or plastic material, it does not have the function of preservation and antibacterial. SUMMARY OF THE INVENTION [0003] The t...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a fresh-keeping, antibacterial, and fully degradable packaging bag or packaging box manufacturing process. The fresh-keeping rate of the packaging bag or packaging box produced by this manufacturing process can still reach 99.8% after 24 hours. %, its antibacterial rate after 24 hours can also reach more than 99.8%, and it is packed into water and oil respectively, and there is no watermark or mimeograph on the surface of the packaging bag or packing box within 72 hours, that is, adopt the present invention The packaging bag or packaging box produced by the advanced production process has excellent fresh-keeping performance, excellent antibacterial performance, excellent waterproof performance, excellent oil resistance performance and excellent degradation performance, which not only overcomes the current packaging bag or packaging box. It does not have fresh-keeping and antibacterial functions, and it also solves the problems of poor waterproof effect, poor oil-proof effect and long time required for degradation of packaging bags or packaging boxes made by the film-coating process
