What are the measures to avoid the ageing of aluminium foil bags?

Aluminium foil bags are bags made from a combination of plastic films laminated by a bag-making machine and used for packaging food, pharmaceuticals, industrial products and daily necessities. Aluminium foil bags are suitable for moisture-proof and light-proof packaging of large machinery and equipment, chemical raw materials and pharmaceutical intermediates. The aluminium foil is mostly in four-layer structure, which has good water and oxygen barrier function. It can be made into flat pockets, three-dimensional bags, organ bags and other styles.

Measures to avoid the aging of aluminum foil bags are as follows:

1, aluminum foil bag is in the natural environment, that is, in direct sunlight conditions, - after a week its strength dropped about 25%, after two weeks will drop about 40%, basically can not be used. That is to say, storage and storage issues are very important.

2. Aluminium foil bags in the open air after the packaging of goods by direct sunlight, the strength will drop sharply, so try to avoid the direct sunlight.

3. Excessive participation of recycled materials is also one of the reasons for the ageing of packaging bags.

4, aluminum foil storage and transportation process, the temperature is too high or encounter rain, will lead to its strength decline, and then fail to protect the quality of the items contained in the requirements, so in ordinary times should avoid high temperature and rain wash.
