Types of paper bags
Depending on the type of bottom:
- Sewn bottom
- Glued bottom
Depending on LDPE liner:
- LDPE liner is glued with the edge of the paper bag (Z-fold) – for automatic filling lines
- LDPE liner has an overlap over edge of paper bag (attached to the bottom in points or sewn) – for manual or half-automatic filling lines, where the liner is manually welded or tied
Depending on paper used:
- Bleached paper (B) – 80 g/m2, used usually for outer layer only
- Brown paper (natural N) – 70 g/m2, used for both inner and outer layer
- Inner layer with LDPE spraying (70 + 20 g/m2) is used mainly as inner liner, but provides weaker protection compared to LDPE liner
