PP synthetic paper is a modern papermaking technology, with polypropylene resin as the main raw material, and may add inorganic fillers (such as calcium carbonate), through a special process of processing paper. The following is a detailed analysis of PP synthetic paper:

Basic definition

Raw materials: Polypropylene resin (Polypropylene, referred to as PP) is the main raw material, supplemented by inorganic fillers and other additives.

Manufacturing process: through stirring, melting, extrusion and other processes to form a continuous web, and then through cooling, winding, cutting and other processes made.

Characteristics: Combining the convenience of paper and the excellent performance of polypropylene materials, it has the dual characteristics of plastic and paper.

2. Material characteristics

Physical properties:

Has strong tensile strength, wear resistance, water resistance and oil resistance.

Light specific gravity (density is generally less than 0.8g/cm³), good rigidity.

High strength, puncture resistance, tear resistance (especially transverse), wear resistance, good folding resistance.

Chemical stability:

100% water, chemical and grease resistant.

UV stability is good, not easy to yellow.

Printing adaptability:

The whiteness and opacity of the paper can reach more than 90%, and the masking is good.

Smooth surface, stable size, high quality printing performance.

A variety of printing methods and solvent inks can be used, such as lithography, letterpress, gravure, offset, screen, flexographic, etc.

Environmental protection:

The source of raw materials and the manufacturing process will not cause environmental change and damage.

The product can be 100% recycled after use, even if incineration treatment will not produce toxic and harmful gases.

Replacing paper with plastic and wood with plastic can save a lot of forest resources and reduce environmental pollution.

Three, the main use

PP synthetic paper is widely used in many fields due to its unique properties:

High quality printing: such as airbrushed posters, airbrushed posters, pictures, maps, calendars, books, etc.

Packaging use: such as handbag, packaging box, pharmaceutical packaging, cosmetic packaging, food packaging, industrial product packaging, etc.

Special uses: such as in-mold labels, pressure sensitive labels, thermal labels, paper currency paper, color image paper, tracing paper for CAD, industrial computer and instrument recording paper, express envelopes, clock plates, paper fans, umbrellas, travel paper caps and other tourism promotional supplies.

4. Summary

PP synthetic paper is a multi-functional material that combines the convenience of paper and the excellent properties of polypropylene material, with excellent physical properties, chemical stability and environmental protection. Its wide range of application fields and unique performance advantages make PP synthetic paper play an increasingly important role in modern society.
