Let’s use data to speak： The smaller the oxygen barrier value, the stronger the preservation function. There is another anti-oxidation index, which is moisture resistance, but the barrier function mainly depends on the anti-oxidation index. For example: the oxygen barrier value of compost real material is 3, nylon is 50, PE and OPP are 2000, it is obvious that compost material is better than nylon in preservation.
