Background
In order to improve the environment, reduce pollution and save cost, recycling of the non-setting adhesive waste has been increasingly paid more attention by people. In 2016, the total consumption of labels in the whole country is 115 hundred million to 130 hundred million square meters, wherein the wet glue label accounts for 55 percent, and the consumption is 63 hundred million to 72 hundred million square meters; the self-adhesive label accounts for 35 percent, and the consumption is 35 hundred million-40 hundred million square meters; in-mold labels, sleeve labels, heat shrink labels, etc. account for 10% in total.
The basic condition of the waste self-adhesive labels in China is that the base paper to be treated by a self-adhesive coating factory, a printing factory and a terminal user is about 35 to 40 hundred million square meters every year. Wherein the printing plant is required to process 1.75-2 million square meters of face stock with adhesive (calculated according to 5% waste per square meter) and 0.7-0.8 million square meters of waste material (calculated according to 2% waste per square meter) produced after die cutting and waste discharge every year; coating plants need to process 0.7-0.8 billion square meters of waste material per year (calculated as producing a 2% rejection rate per square meter). The existing method for recycling the waste adhesive sticker mainly comprises the following steps: the method for directly burying or burning the waste materials to generate electricity can cause secondary pollution and waste useful resources in the waste materials. Because the waste can not be recycled, social public nuisance is caused, the method directly relates to the civil problem and causes pollution to the environment.
