How To Separate Paper-plastic Composite Bag

On how to separate the paper-plastic composite bag, the method that can make the paper-plastic composite bag recyclable again:

First, pure heating

Place the paper flat on the heating plate, and then heat through the heating plate; When the temperature reaches 150℃ ~ 280℃; After heating for 20 to 50 seconds, the plastic on the paper-plastic composite material will begin to deform, shrink, and separate from the paper. This method can separate the waste paper plastic composite bags that can not be treated before, so that the waste paper can be reused, such as: the waste paper can be used for pulping and papermaking; The use of waste plastic can be recycled granulated, and then re-drawn to make paper plastic composite bags, or injection molding into new other plastic products. This method can turn waste paper plastic composite bag into treasure, and also solve the problem of environmental protection, so that it has great economic and social benefits.

2. Dissolution method

The waste paper plastic composite bag as raw material, dissolve it with organic solvent to separate the paper monomer, and then carry out the beating paper process, the raw material is put into the organic solvent dissolution tank, after heating, stirring, dissolve the plastic layer, separate the paper monomer and other monomer layer, and so on after drying, the paper will be selected for beating paper. The method is simple and feasible, the separation efficiency of paper-plastic composite bag is high, the effect is ideal, and the separated paper can be used for papermaking, reducing the production cost of papermaking. The woven bag can be used to recycle the woven bag or other plastic products, so as to realize the comprehensive utilization of resources, protect the environment and make greater contributions to the cause of environmental protection.
