Multi-Wall Paper Pasted Valve Bags

Sustainably sourced from the highest quality papers and films. Our full complement of valve bag types and styles carry a broad range of industrial materials across the globe.


Built for Speed and Durability

A Pasted Valve Stepped End ("PVSE") multi-wall paper bag is a common industrial packaging style designed to package a wide variety of dry flowable products. Valve bags are packed on equipment that deposits material into the bag via a horizontal filling spout. When the bag is discharged from the packing equipment forces generated by the product inside the bag allow the valve opening to self-seal.

The valve bag construction results in a squared-up bag, which palletizes very securely and can be printed with product information on the side or end panels for easier product identification in pallet loads.

Features & Benefits

  • Ideal for packaging building materials, chemicals, minerals and agriculture
  • Designed for high speed filling
  • 20-100lb Capacity
  • Manufactured with 1-6 plies of paper
  • Multiple valve configurations for unique filling requirements
  • Multiple moisture barrier options

  • Perforated paper for fast air evacuation

Valve Types

Valve bags are filled through an opening located in the top corner of the bag. Product is pumped or forced into the bag via air pressure, impeller, or auger. When the bag is discharged from the packing equipment, forces generated by the product inside the bag allow the valve opening to self-seal.

Valve bags can be equipped with different valve or “sleeve” types. Each sleeve type performs the same basic function. However, the proper sleeve type for your product and packing equipment needs to be evaluated when designing a valve bag. Our valve type capabilities include:

  • Double Trap
  • Reinforcing Strip
  • Paper Tube Insert
  • Reinforced Poly Lock
  • Tuck-In
  • Hinged Tuck-In
  • Sonic/Heat Seal
  • Double Trap Sonic Seal
  • Reduced Sleeve
