company news about Waste paper recycling, quality detection is the key

From recycling to recycling:The whole process of paper transformation into recycled paper is revealed

Recycled paper, commonly known as waste paper, takes waste paper as the main raw material and is processed by multiple processes. The production process of recycled paper has become an environmentally friendly production method. Compared with traditional paper making, the production process of recycled paper is more concise, economical and environmentally friendly, which greatly improves the efficiency of resource utilization.

The production process of recycled paper includes the following steps: collection, sorting, screening, pulping, papermaking, processing and so on.

According to its use and characteristics, recycled paper can be roughly divided into two categories:

            One is practical paper for daily life, such as hanging panel paper, toilet paper, etc.;

             The other is the cultural paper that carries knowledge and information, including books, newspapers and magazines, copy paper, printing paper, postcards and exercise books;

In China, cardboard, cartons, paper bags and newsprint are widely used in all walks of life.

The quality of waste paper recycling is related to the quality of recycled pulp and the final paper, and subtle defects may lead to quality problems or safety risks during the use of the product. Therefore, comprehensive and strict testing of the whole process from waste paper to recycled paper is the key to ensuring product quality and safeguarding consumers' rights and interests.

The main test items are as follows:

Appearance test: paper smoothness meter, whiteness meter, thickness meter and other test instrument;

Moisture permeability test: absorbency, moisture meter, permeability and other test instrument;

Performance test: rupture strength, tear strength, tensile strength tester.
