Plastic packaging factory knitting for your answer: packaging plastic bags original bulk. This is the traditional form of packaging, because of inconvenience, transportation, storage and other reasons, has been explicitly prohibited by the state, but because of historical reasons, in some localities there are varying degrees.
Packing plastic bags. Generally, it is divided into 1 kg, 2 kg and 5 kg. This is the method adopted by many Chinese medicine processing enterprises or Chinese medicine shopping malls to deal with the need for packaging of Chinese medicine pieces. However, it is only the packaging of the original large sacks and fibre bags. In essence, there is little change, and there is potential damage due to the wide use of plastic bags. At the same time, because of the incompatibility between packaging materials and the nature of drugs, the secondary pollution of traditional Chinese medicine pieces is simply formed, which leads to mouldy worms and the mutual solubility and infiltration of organic components in fat-soluble pieces and plastic guesses.
Environmental plastic bags are made of natural macromolecule resins. After adding various additives, it has ductility under certain temperature and pressure, and can fix its shape after cooling. The process of plasticizing natural or constitutive macromolecule resin molecule in melting state and adjacent homogeneous dispersant molecule is called plasticizing. The process of plasticizing arrived in early years is called plasticizing in early years. It has not arrived yet and is considered not plasticizing.
Of course, environmental plastic bags are now two-position packaging materials, and their applicability is not as good as paper and cardboard packaging. But the plastic vacuum packaging industry opens at a rate of 5% a year, while other plastic materials, including paper and cardboard, metal, glass, pottery inkstone, linen and cotton, are only added at a rate of 2%. So one day, the plastic packaging industry will leap over paper and cardboard to become a packaging material.
