Synthetic paper (synthetic paper) is the use of chemical raw materials such as olefins and then add some additives made of, with a soft texture, tensile strength, high water resistance, light resistance to heat, and resistance to chemical corrosion and no environmental pollution , Good ventilation, widely used in high-level art, maps, pictures, high-end books and other printing.

Origin and development

Synthetic paper is made of polyolefin resin and inorganic filler as the main raw material, through the extrusion process, and has the characteristics of plastic and paper versatile materials. Synthetic paper is a new plastic material products, but also an environmentally friendly products, with a light weight, high strength, tear resistance, good print, shading, anti-ultraviolet, durable, economic and environmental protection and so on. As the synthetic paper production process without pollution, can be 100% recovery, recycling, is a major reform of modern paper production.

Synthetic paper has been abroad for more than 30 years of development history, especially in the United States, Japan, Canada and other developed countries, China Taiwan started earlier, faster development. With the strengthening of global environmental awareness, ordinary fiber paper caused a lot of pollution, speed up the development of synthetic paper, the new synthetic paper varieties continue to expand the scope of application of synthetic paper. At present, the world sales of synthetic paper products to 10% annual rate of increase, synthetic paper part of the ordinary fiber to replace the pace of accelerated.

species

Synthetic paper, PVC synthetic paper, PET synthetic paper, ABS synthetic paper, etc .; according to the different filler, divided into filled CaC03 (calciumcar), synthetic paper, (Clay type, SiO2, Al2O3) type, SiO2 (silica) type, mica (talc) type, TiO2 (titanium dioxide) type and composite (two or more filling) type; according to the different production methods (Such as CPP), blown film method (such as HDPE), two-way stretching method (such as BOPP, BOPET), etc .; according to the different structure, divided into single-layer synthesis Paper, three synthetic paper, five layers of synthetic paper.

Features

1, economy. Calcium carbonate (CaC03) mineral filling, weight ratio of up to 60%, can effectively reduce the consumption of plastic, but also recycling, calcium carbonate low price, and stable.

2, environmental protection. PP synthetic paper raw materials and manufacturing process will not cause changes in the environment and damage, the product can be 100% after the recovery, even if the incineration, because the plastic substrate only carbon and oxygen elements, will not produce toxic and harmful gases. To plastic and paper, to plastic and wood, synthetic paper raw materials do not need wood and natural plant fiber, you can save a lot of forest resources and reduce environmental pollution.

3, the proportion of light (density is generally less than 0.8g / cm3), good rigidity.

4, very durable, high strength, anti-puncture hole, tear (especially horizontal), wear resistance, good folding resistance.

5, without natural fiber, 100% waterproof, anti-chemical and anti-grease.

6, paper whiteness and opacity can reach more than 90%, good shelter, good UV stability.

7, the surface is smooth, stable size, high-quality printing performance, printability is good, can be used lithography, Toppan, gravure, offset, screen, flexographic (aniline) and other printing methods and solvent inks, pencil, Direct writing.

8, good processing, can be used cutting, die cutting, embossing, bronzing, drilling, sewing, folding, bonding and other processing methods.

9, long shelf life, moth, anti-corrosion.

10, can replace the composite, spray aluminum, Lin Mo and other composite paper products.

11, can be allowed in direct contact with food.

application

As PP synthetic paper at the same time with the characteristics of plastic and paper, so in many ways has a wide range of applications, mainly in the following three areas:

1, high-quality printing. Such as posters, pictorials, pictures, maps, calendar, books and so on.

2, packaging purposes. Such as handbags, packaging, pharmaceutical packaging, cosmetic packaging, food packaging, industrial products, such as packaging.

3, special purpose. Such as in-mold labels, pressure sensitive labels, thermal labels, paper paper, color paper, CAD tracing paper, industrial computer and instrumentation recording paper, express envelopes, clocks, paper fans, umbrellas, Other travel promotional items.
