Advantages of paper and plastic packaging bags and recycling

Paper and plastic bag, also known as three-in-one composite paper bag, is a small bulk container, mainly by manpower or forklift truck to achieve unit transportation, it is easy to transport small bulk powder granular material, with high waterproof, excellent in appearance, easy loading and unloading and other characteristics, is one of the most popular and practical ordinary packaging materials. With the improvement and development of the process, paper bags have been more and more widely used: industrial packaging, food packaging, electronics, aerospace, technology, military and other fields are paper plastic woven bags (cloth) as the base, made after the extension method (two in one, cloth / film / paper composite is three in one). They are mainly used for packaging chemical fertilizers, synthetic materials, explosives, grain, salt, minerals and other powder or granular solid materials and flexible items.

Advantages of paper and plastic bags:

 1. High strength: paper-plastic composite bag, the inner layer is PP or PE woven cloth, the outer layer is refined compound kraft paper, the middle is composite plastic, etc. This product has a strong puncture and tear resistance characteristics.

2. Beautiful appearance: made of yellow or white refined kraft paper, three-color printing with bright appearance.

3. Good anti-slip resistance: choose brown paper above 25 degrees, easy to fold.

Environmental protection has always been the act of resource protection advocated by the state. At present, the phenomenon of resource waste in China is not serious, in different industries will have this situation, in order to reduce this phenomenon, plastic bag enterprises produced paper plastic bags will effectively avoid this waste phenomenon, the waste paper plastic bags through separation can make paper plastic bag recycling, there are usually two methods:

First, through the pure heating method

 Place the paper surface of the paper composite flat on the heating board, heated through the heating plate; when the temperature is between 150 ℃ and 280 ℃; after 20-50 seconds of heating, the plastic on the paper composite begins to shrink and separate from the paper. The method can separate the waste paper plastic bags that cannot be treated, so waste paper can be recycled, pulp and paper, waste plastic recycled particles, recycled paper and plastic composite bags or injection into new plastic products. This method can combine waste paper-plastic composite bag into waste, and solve the environmental protection problem, so it has great economic and social benefits.

Second, the monomer is separated by the dissolution of the organic solvent

Take the waste paper and plastic composite materials as raw materials, dissolve and separate the monomers with the organic solvent, and the pulp and paper making process is carried out. The raw materials are in the dissolved canal of the organic solvent, dissolve the plastic layer after heating and stirring, paper and plastic composite, and separate the monomer and other monomer layers. After drying, select pulp and paper. The method is simple and feasible, with high separation efficiency and ideal effect for paper-plastic composite bags. Separation paper can be used for paper production cost, woven bags or other plastic products, realizing comprehensive utilization of resources, protecting the environment, and has good social and economic benefits.

Through separation can let paper and plastic bags be used again, do not cause serious waste phenomenon, to ensure that the national resources can be fully utilized, thus reducing
