These two materials are able to prevail in the market, is its low price, compared to the new material, the substandard secondary materials even less than half the price.

If the circulation of the plastic in the field of food, medicine and other packaging, direct access to the food and drug harm to people more.

Development of cosmetics to promote the development of tube packaging
With the rapid development of composite technology of plastics and different materials, composite tube gradually enters a variety of different packaging fields, such as high quality cosmetics, with its excellent water resistance, oxygen resistance and other properties and good convenience.
