Custom Valve Bags

Plastic valve bags with an R Valve style are used for microscopic powders such as talc, glitter, or other tiny particles. Plastic valve bags with a T Valve are used for such products as sand, chemical resins, animal feed, and agricultural seeds. Plastic valve bags with an open mouth are the more traditional bags used for such products as dog food. We can even produce plastic valve bags with an R Valve style that are batch inclusion/low melt bags. These particular plastic valve bags are made to melt at certain temperatures and to dissolve completely. This increases productivity and reduces worker exposure to the products themselves. Using monolayer, multi-layer and co-extruded (3 layer) films, along with various options such as micro-perforations that allow products to ``breathe``, embossing patterns to keep pallet loads secure, and anti-slip materials for greater stability and stacking.

Features of Plastic Valve Bags

• Styles: R Valve, T Valve, Clean Fill and Open Mouth
• Materials: Polyethylene and Laminated Films
• Options: Embossed (nonskid) and Ventilation Patterns
• Printed or Plain

Benefits of Plastic Valve Bags

• Plastic valve bags are made using monolayer, multi-layer with anti-slip for greater stability for handling and stacking, and coextruded (three-layer) films.
• We are able to print plastic valve bags up to 8 colors using the latest generation of equipment and technology.
• Our plastic valve bags are made with FDA approved components.
• Our plastic valve bags are heat sealable and available printed or plain.
• We can run small and large volumes of plastic valve bags.

  Performance characteristics of different valve bags

   Low Melt (temperature resistant to 110º C or 230º F) - Batch Inclusion

   Standard (temperature resistant to 165º F)

   Hot Filling (temperature resistant to 185º F)

   High Strength (Hazardous goods)

  Bag Conversion

  Bag Ventilation

   Slow to quick venting (usually used when packaging sand, limestone, rubber, and similar products - 1/2" x 1/2" spacing and the front is offset from the back)

   Slow venting (provides a good moisture barrier & usually used when packaging fertilizer or similar products - 2" x 2" offset spacing)

   Quick and clean venting (usually used with powders - only the face of the bag is vented)

  Typical valve bag construction

   1Poly / Plastic (Quicker production than paper)

   Paper (Higher quality printing)

   Paper with liner (presents a better moisture barrier / More efficient valve / Cleaner filling)

   2-ply or 3-ply

   One or two-ply
