Jenton granted patent for new style valve bag

01 April 2020

Jenton International has been granted a European patent for its method of manufacturing a new type of valve bag.

The heat sealed film bag has been specially designed for packaging small items including hardware, small parts and especially foods such as soft fruits, cherries or snacks, including nuts and raisins, with some liquids also possible.

Jenton’s valve bag creates a ‘one way valve’ at the top from the folded and sealed material of the bag. The advantages of a valve bag include product containment without the need for any form of bag sealing and secure food packing which still qualifies as ‘packed open’. 

Richard Little, Jenton’s Managing Director says: “Users can, for example, take a cherry from the bag and then turn the bag upside down and none of the others will fall out.”

The patent primarily relates to how Jenton’s innovative low density polyethylene (LDPE) Valve Bag can be manufactured to very small sizes on side-weld or pouch making machines without the converter needing to invest in expensive in-tube sealing heads or modification of an existing production line.  Normal bag machine speeds are possible.

Richard adds: “There are so many applications for this valve bag, from allowing flowers to be shipped in water to secure entrapment of medical low hazard waste. It would require very little modification of existing production lines in order to manufacture the bag and we are keen to work with manufacturers who may wish to licence the IPR.”

Having been involved in introducing bread bagging technology to the UK market in the 1960s, Jenton has a track record of innovation in the converting industry.  At its Whitchurch-based facility, Jenton Group offers a full workshop and maintains an extensive stock of spares in addition to having a number of skilled service engineers available for on-site repairs and maintenance. www.jenton.co.uk
