Kraft Unbleached SPX®
SPX® is an outstanding, high-performance multi-wall paper. It combines remarkable cross-direction strength with added stretch in the machine direction creating a superior balanced sheet for today’s bag manufacturing equipment.
SPX® is more cost-effective than conventional papers in several ways:
- Even stronger than SPK®
- Converters running two-ply versus three-ply use up to thirty percent less paper per bag.
- Machines can run faster with fewer roll changes.
- Less paper inventory is needed.
- More bags stacked per pallet cutting shipping costs.
Multi-wall bags made from SPX® use less paper in demanding applications such as:
- Agriculture (e.g. Feed, seed, sugar)
- construction (e.g. cement)
- and other materials
SPX extensible high performance kraft paper has superior Tensile Energy Absorption (TEA) and balanced strength characteristics in both the machine and cross direction. Even stronger than SPK , multiwall shipping sacks made from SPX use less paper in demanding applications for a variety of products such as cement and other construction materials. Typically used in pasted valve sacks.
