Product Description

Apparel Packing Large Bubble Envelopes , Self Seal Bubble Mailers 380x330 #B4
The pressurized kraft paper is mainly used in the pressing process of FPC, PCB, CCL and other industries. It plays the role of heat preservation, water absorption, decompression, buffer and heat transfer during the process of press plate. It has all kinds of weight, providing 190g/m&sup2, 220g/m&sup2, 254g/m&sup2 and other different weights for years, and can provide customized production services from 190g/m&sup2 to 450g/m&sup2 for customers.
1. paper is smooth and clean. No, so as not to affect the quality of plate suriko wrinkles, pores, sand etc..
2. good hot press elasticity, high flatness, significantly improve the quality of compression and improve the product yield.
3. the heat transfer performance is smooth, uniform and no fluctuation, and the heat transfer rate is moderate.
4. reel paper end is flat, no more than 2 pieces of paper joint.
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.
