Product Description
PO flat moisture-proof and dust-proof packaging bags are a very practical packaging material, mainly used to package various electronic components, cosmetics, medicines and other products and items that have strict requirements on moisture and dust. PO refers to Polyethylene Oxide. The advantages of this material are that it has good flexibility and ductility, high strength, strong resistance to moisture and temperature changes, and is not easy to break. It is a very reliable material.
The production process of this flat bag is to use a low-pressure flat mouth blow molding machine to heat the polyethylene alkoxy at high temperature, straighten the film by exhausting air, and then perform cutting, sealing, bag making and other processes to form a finished product. This production process has the advantages of low cost, fast production speed and high efficiency, and can meet the needs of mass production.
PO flat-mouth moisture-proof and dust-proof packaging bags are very simple and convenient to use. Just put the items in the bag and then seal the bag by heating or compression. This kind of packaging bag can not only effectively protect the items in the bag from moisture, dust and other pollution, but also has good transparency, which can facilitate the inspection of the packaged items.
