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.
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 expelled from the packing equipment, the internal forces exerted by the contents prompt the opening of the valve bag to self-seal. This design feature of our bags ensures secure containment and hassle-free handling, providing peace of mind during transport and storage.
Bags with valves 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
