Papermaking raw materials are divided into two categories: plant fiber and non-plant fiber (inorganic fiber, chemical fiber, metal fiber), etc.

The international papermaking raw materials are mainly plant fibers. Some economically developed countries use conifers or hardwood materials accounting for more than 95% of the total consumption.

There are many varieties of plant fiber raw materials used in our country, which are divided into six categories:

1.Coniferous wood, such as larch, red pine, masson pine, mongolica, Yunnan pine, etc.;

2.Broadleaf trees, such as poplar, birch, eucalyptus, etc.;

3.Grass plants: such as reeds, bamboo, wheat straw, rice straw, asparagus grass, sorghum stalks, bagasse, etc.;

4. Bast fibers, such as flax, jute, kenaf, sandalwood bark, mulberry bark, cotton stalk bark, etc.;

5. Kinds of wool fibers, such as cotton, cotton linters, cotton rags

6. Waste paper fibers are classified as first-class waste paper according to our country’s custom (white paper edges and broken paper picked from factories or related units without printing).

Second-class waste paper (printed waste books, newspapers) .Third-class waste paper (all waste paper, old cardboard, and torn cardboard boxes except for the above two types), etc.

Plant fiber is degradable. For the sake of environmental protection, WiAIR's cushioning kraft paper uses plant fibers, which is made from the long fibers of coniferous trees, it makes paper cushion fiber longer, less likely to break and more resistant than ordinary cushioning paper.

Honeycomb paper made from long fibers of conifers has good stretchability.

In addition, the stretched honeycomb paper has good cushioning properties and is more compressive.

Among them, the three-fold paper extruded from the folded paper and the roll paper can withstand items below 60kg

FSC Forest Certification

FSC forest certification, also called timber certification, is a tool that uses market mechanisms to promote sustainable forest management and achieve ecological, social and economic goals

(FSC Forest Certification Mark)

Not all buffer papers can meet environmental protection standards. Only paper made of wood and wood pulp that meets FSC forest certification can achieve true environmental protection.WiAIR cushion paper are all in line with FSC forest certification, and do not use cushion paper produced from pulp made from hacked and felled wood on the market.
