Introduction
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 : | AL | | Melting Point : | 660℃ | | Working Temperature : | -180~240℃ | | Material Density : | 2.7g/cm³ | | Conventional Size : | 120x165 #FD-MO- | | Sample Color : | Wheat | | Basic Material : | Aluminum Foil | | Protruding Characteristics : | Radiation Proof | | Application Industry : | Office | | Shape Style : | Drawstring |
| Speciallity | | In order to meet the new demand of food manufacturers for
packaging, raw color Kraft boards are different from those of
bleached cardboard, such as baked food or convenience food. The
natural brown appearance of the original color kraft paper has a
healthy and antique flavor. In fact, the distinctive contrast
between the unique appearance of the kraft paper and the large
amount of white packaging can also make the product more prominent.
Because many of the food packaging is designed to provide
convenience or practicality, the strength of the kraft paper is
another advantage. The outer packing must be strong enough so that
the customer's meal can be wrapped without leaving it off. In the
same way, the drink cup must be kept in a wet environment so that
coffee is not allowed to flow to the customer's thighs. Intensity
is also a major consideration for frozen foods, because the
packaging of frozen foods can not be deformed, torn, distorted or
absorbed too much in the freezing / thawing cycle. In terms of
practicality, kraft paper is better than homogenous bleached kraft
paper. | | | |
