Overview

A closed bag designed for high-speed filling through a valve on spout packers (e.g. 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 optimised according to the customer’s needs. Valve bags can be equipped with PE-free film or PE-Inliners where enhanced moisture protection is needed.

Benefits

  • 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 by ultrasonic, 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 can be optionally applied to improve frictional characteristics.

Optional features

  • Easy Seal / Ultrasonic Sealable Valve: for cleanliness and enhanced product protection
  • Easy Open: integrated tear-open strip
  • Security Label: highly sophisticated anti-counterfeiting label
  • Handle: for enhanced end user convenience
