The difference between three kinds of airlaid paper:
- Glued airlaid paper is made by laminating the wood pulp fibers after being air-laid;
- The heat-sealed airlaid paper is a mixture of wood pulp fibers and hot-melt fibers, and the fibers are mainly bonded by melting of the hot-melt fibers;
- The integrated airlaid paper is bounded between the two, both the bonding of hot-melt fibers and a small amount of latex bonding.
But in fact, heat-sealed airlaid paper must also be surface-foamed (similar to surface sizing) to finish the surface. Compared with the usual glued airlaid paper, the heat-sealed airlaid paper has more excellent properties in terms of bulkiness, dry-wet tensile strength, flexibility and liquid absorbing properties.
Airlaid paper applications: semiconductor production lines, microelectronics production, LCD display, LCD display, circuit board production, PCB products, screen printing, laboratory dust-free workshop production line.
