Biodegradable bubble Wrap Shipping Envelopes , Size 6 12.5 X 19 Bubble Mailers
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.
Convenient self-seal closure saves labor and eliminates the need for staples and tape, while forming a water-resistant, secure package.
Kraft exterior presents a quality image and makes an excellent surface for custom printing.
Made from 100% recycled content.
Kraft bubble mailers or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process.

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.
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.
