Pasted Valve Bags

A closed bag designed for high-speed filling through a valve on spout packers (gravity packer, impeller packer, air packer, screw packer or grooved belt packer). Valve bags deliver top performance wherever high-speed filling processes are used. Filling performance and protection properties can be fine-tuned according to the customer’s needs. Valve bags can be equipped with PE-free film or PE-Inliners where enhanced moisture protection is needed.

High-speed filling Valve bags are designed for quick de-aeration and high filling speed.
Flexible closure options The valve can either be self-closing by the pressure of the product, closed by sticking down/tucking in, heat sealed or embossed, depending on the required level of sift proofness and the need for a clean work environment.
Optimal palletisation Valve bags help ensure optimally shaped pallets, due to sturdy bag constructions. coatings to improve frictional characteristics can be optionally applied.
Optional Features
Easy Seal / Ultrasonic Sealable Valve Where sift proofness for cleanliness or enhanced product protection of sensitive goods are required Mondi's ultrasonic sealable valves are ready to serve your need. Easy Seal is optimised to accelerate your production process and energy consumption. The bags can be equipped with a seable valve upon request. Mondi gladly advises you on the best suitable sealable valve products for ultrasonic sealing.
Easy Open
An integrated tear-open strip allows easy opening of the bag to quickly release the content. This feature avoids paper shreds, which may contaminate the filling good when opening the bag with common devices  and at the same time eliminates risks of injury.
Security Label The highly sophisticated anti-counterfeiting label successfully combats product forgery.
Handle For enhanced end user convenience an optional handle for better carrying comfort can be produced with the bag.
