Nano fresh-keeping bag/film

This nanometer-scaled bag can deliver three outstanding advantages:

A) The bag can automatically adjust the proportion of oxygen and carbon dioxide and nytrogen in the bag to the optimum combination, which will effectively hinder breathing of the packaged vegetable or fruit for a longer shelf life.

B)This bag can effectively contain bacteria breeding inside the package to protect the product from deterioration, so as to remarkably lower the perishing rate.

C)Good breathability to allow the wator vapor to transmit through the bag to prolong the shelf life of packaged products.
