First, there was SPK®, super performance kraft, and now there’s SPX® - an even tougher, stronger paper for two-ply, multi-wall packaging.

Together, SPX® and SPK® keep bag converters on the cutting edge from North America to Europe to Latin America. They’re two super performers!

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:   

• 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.   

SPX® Velocity offers these additional advantages:    

• Shorter Sack - SPX® Velocity air permeability means no requirement for internal void space in sacks during filling. This allows converters to shorten the bag length, reducing the sack size.   
• Clean Packaging - No perforations eliminate dust and keeps the bag surface clean.   
• Rapid Filling - Porous paper is superior to perforation for air evacuation. The faster air is evacuated from a pasted valve sack, the faster it can be filled and palletized.

SPX® Vector - The Single Ply Solution    

This single ply solution provides the performance characteristics and cost reduction bag users require, and the runnability converters need.   

• Reduced packaging - Less paper per sack.   
• Excellent porosity - No perforations means cleaner handling for the packaging plant, point of purchase and end user.   
• Strong Sack - Means faster fill speeds and a stronger bag for demanding applications.   
• Increased stiffness- Compared with 2 ply 70gsm (43#) bags, one ply SPX® Vector bags run faster due to increased stiffness obtained by a heavier weight one ply.   
• Cost savings         
  • Less paper per sack         
  • Stiffness allows production of sacks at higher speeds         
  • Less waste         
  • Faster changeover
