Fabric is opened on both sides to control flatness for multilayer lamination.

Film layers address lamination bonding and film strength, with the configuration selected for the material and filling conditions.
Extensible virgin-pulp paper
Imported extensible virgin-pulp kraft paper is checked for water resistance, tensile strength and elongation.
