The above-mentioned problems have now achieved a breakthrough development. The raw materials have been able to produce PLA (polylactic acid) _ on the surface layer, which produces the effect of self-digestion; however, it can only provide natural decomposition effects, but it still cannot be achieved. For the preservation of the function of sterilization. In order to achieve the effect of fresh-keeping and sterilizing, and to achieve the natural decomposition effect of natural decomposition, the coating technology is made into a paper container, and the screaming has a resistance to rice and silver mixed ς ^ film, # can achieve sterilization and preservation, but this For non-general laminating technology, it can reach [invention content] Eight stations and one f can be used to solve the problem of 眺 眺 眺 _ _ _ _ , , , , , , , , 层 层 层 层 层 层 层 层 层 层 层 层 层For polylactic acid 8〇~ too, the ratio is 5~20% ' _ mix and mix, through the melt wire device '= j acid nano silver composite wire, and then the polylactic acid nano silver composite wire into 'acid, The silver particles 'and the polylactic acid nano silver particles are melted through the laminating machine==Bai Lishui Nai Lai', when the silver is thin, the processor (CORONA) is electrically shocked at 5K~50KW士=一橡_5~28.
