Speciallity
At room temperature, it is insoluble in general solvents, but it can swell in fatty hydrocarbons, aromatic hydrocarbons and halogenated hydrocarbons for long time, and it is slightly soluble in toluene and acetic acid when it is above 70 degrees.

Brief Introduction
Kraft bubble mailers Kraft bubble mailers or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process. Sack Kraft bubble mailers, or just sack paper, is a porous Kraft bubble mailers with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers. Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high quality paper where strength, whiteness and resistance to yellowing are important.

Materials introduction
The co extrusion film is applied to pure milk bags, express bags and metal protective films. It is characterized by good tensile properties and good surface brightness. In the process of thin film, a kind of raw material is extruded into another kind of film which has been made, or the different kinds of films have been bonded together to form a multilayer film, which is called composite film. Most of the material of the composite film is plastic, but it can also be made of paper, metal foil (usually aluminum) or fabric. The basic requirement of composite film is good bonding between the layers to ensure the overall mechanical properties of the packaging.
