EVOH Barrier Liner

Oxygen barrier with the handling behaviour of PE

The problem it prevents

Colour drifts. Aroma fades. A batch is downgraded. Very few people connect that back to the liner.

The loss shows up as a quality complaint, not as a packaging complaint. Products that oxidise, lose their aroma, change colour or break down in the presence of oxygen need a barrier that polyethylene on its own cannot give.

If your quality team is seeing shelf life complaints they cannot explain, oxygen coming through the liner is worth ruling out first.

EVOH is specified where oxygen is what spoils the product.

What it is

EVOH has an excellent barrier property against oxygen and the outside atmosphere. It is used as the barrier layer where oxygen getting in is the controlling problem.

The EVOH layer is co-extruded between polymer layers, so it gives an oxygen barrier while keeping the sealing behaviour and flexibility of an ordinary PE liner.

Key features

  • High oxygen barrier performance
  • Protects aroma, colour and product stability
  • Extends usable shelf life in bulk storage
  • Keeps the sealing and handling behaviour of PE
  • Available in bulk bag, box type and baffle constructions

How we build it

We have built EVOH into box type and baffle constructions, not just plain tube liners. This means you can have oxygen protection and shape control together instead of choosing between them, which is where most suppliers stop.

We will run a side-by-side trial with you: one batch in your current liner, one in EVOH, checked at the same interval.

Built to your specification

Every one of these can be changed for your application, and a sample is supplied for trial fitment before bulk production.

  • EVOH layer thickness
  • Total layer count
  • Box type or baffle construction
  • Dimensions and fitment
  • Food-grade material declaration

Send the drawing, the drum, or the data sheet.

Every product we make is built to order, so the conversation starts with your specification rather than with our price list. Sample liners and trial covers are supplied for fitment before bulk production begins.
