Paper-plastic composite bags are handbags made of paper with a small amount of plastic added. This kind of bags have good toughness and tensile strength, and also have certain waterproof function. They are composed of paper and plastic, which can not only play the role of dustproof, but also waterproof and moistureproof, so they are widely used in food, daily necessities, cosmetics and other industries.
Paper-plastic composite bags are mainly used for the packaging of food, daily necessities, cosmetics and other products. They are the most widely used in packaging food. In paper-plastic composite bags, paper is the main material, while plastic is the auxiliary material. In order to enhance the toughness and tensile properties of paper-plastic composite bags, the plastics used mainly include high-density polyethylene (HDPE), polyvinyl chloride (PVC) and polypropylene (PP). Since the manufacturing process of paper-plastic composite bags is different from that of traditional paper packaging materials, paper-plastic composite bags have the advantages of light weight, high strength, and easy molding, and can achieve waterproof, moisture-proof, compressive, tensile, low-temperature and high-temperature resistance, etc. Function.
Paper-plastic composite bags should also pay attention to many aspects during the application process. For example, paper-plastic composite bags have a certain impact on the environment. A large part of the plastic used in paper-plastic composite bags is non-recyclable petroleum resources. If the use environment is polluted, it will affect the quality of the product itself, resulting in failure to use normally. In addition, there are certain requirements for raw materials in the production of paper-plastic composite bags, including paper and plastic. Paper-plastic composite bags made of different raw materials also have different strengths. During the production of paper-plastic composite bags, it is necessary to pay attention to the control of the types and proportions of relevant raw materials. These materials can all be recycled to make other products.
