Bags with special specifications, produced on the basis of a laminated polypropylene fabric of flat base or rectangular bottom. These characteristics provide the following benefits:
- Resistance to traction
- More hermetic, since it has NO SEWING; It does not use adhesives, and is sealed by hot welding.
- Saving of storage space and/or cargo costs in transport.
- Additional printing designs, increasing the brand’s exposure at the top and bottom of the bag.
- Protection against counterfeiting.
The bag can be either an open mouth bag or with a valve in the part that favors the sealing through an automatic closing mechanism.
Types of Valve
Single Valve:
It is the same product that closes the valve without seams therefore avoiding spillage or loss of the product.
Extended Valve:
It has a filling system that provides a greater degree of sealing. The external valve can be closed by welding.
Pocket or Pocket Valve:
This valve allows the manual closing of the bag, maintaining high levels of sealing.
