Repeat Use | | | | Speciallity | | Production process: LLDPE resin is mainly produced by full density
polyethylene unit. The representative production process is
Innovene process and Unipol process of UCC. | | | | 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. | | | | Data Sheet | | Materials Classification : | PE | | Melting Point : | 112°C~135°C | | Working Temperature : | -95°C~+100°C | | Material Density : | 0.910g/cm³ | | Conventional Size : | 95x155mm #A | | Sample Color : | Cyan | | Basic Material : | LLDPE | | Protruding Characteristics : | Corrosion Resistant | | Application Industry : | Beverage | | Shape Style : | Spout Top | | | | | | | Related Picture | | | | | | Materials introduction | | LLDPE is of low strength, hardness and rigidity, but has a high
ductility and impact strength as well as low friction. It shows
strong creep under persistent force, which can be reduced by
addition of short fibers. It feels waxy when touched. |
