POROUS KRAFT
Semi-Extensible and Fully Extensible Porous Kraft papers available in Brown and White, 70gsm to 120gsm (43# to 74#).
These grades have a low Gurley of 3 to 6 seconds, and are used for packaging powdered products, letting air flow
out of the bag during the filling process thus eliminating the need to perforate the paper.
These papers have been developed to meet the increasing demand for a cleaner, less dusty environment and have
drastically reduced dispersion of packaged powders when compared to perforated bags.
Stretch levels are:
| Semi Extensible: | 4 to 6% |
| Fully Extensible: | 6 to 8% |
These porous papers have the following advantages:
- Less dusting during filling of bags
- Cleaner retail environment
- Cleaner handling by end user
Typical shelf products:
