With the development of packaging technology, dosage, easy to carry small packaging products, more adapted to market trends. So the bar packaging is widely used in all walks of life. Such as the bar packaging in the pharmaceutical packaging, each box of products have many closed small bar bags, a single dose of drugs or single-chip drugs placed in a separate package, take a dose of drugs does not affect other drug packaging.
At present, aluminum foil material is mainly used in the production of automatic packaging film, He is another packaging material used to package solid powders outside the defoaming package.
