Biodegradable bubble Wrap Shipping Envelopes , Size 6 12.5 X 19
Bubble Mailers
Description:
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.

| Brief Introduction |
Kraft bubble mailers
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 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.
