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.
|Production process: two kinds of production processes are adopted by gas phase method and slurry method. The slurry ring pipe production process with Philips Basell companies and the Nordic North Star ring pipe technology as the representative. The rule of the cauldron type slurry is represented by the CX technology of the Mitsui Corp in Japan.|

|The plastic is made of monomers as raw materials, polymer by polyaddition or polycondensation polymerization (macromolecules), commonly known as plastic resin (plastics) or (resin), can freely change the composition and form style, composed of synthetic resin and filler, plasticizer, stabilizer, lubricant, pigment and other additives.
The main component of plastics is resin. The term was first resin secrete by animal and plant lipid and its name, such as rosin, shellac, resin is not mixed with various additives and polymer compounds. The resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of resins, but additives also play an important role. Some plastics are made up of synthetic resins, with or without additives, such as perspex and polystyrene.
The so-called plastic, in fact, it is a kind of synthetic resin, the shape is similar to the natural resin in pine resin, through chemical means of artificial synthesis, and is called plastic.
