Aluminium 5-Layer and 6-Layer Liner

Every layer specified for a job we can explain

The problem it prevents

One rejected container can wipe out the margin on a year of shipments.

The risk sits at the destination, thousands of kilometres away, where you cannot inspect anything. By the time the problem is visible, the consignment has already been refused.

Route, transit time and destination climate decide how much barrier you actually need.

What it is

High barrier liners built in five or six laminated layers. Each layer does a different job, covering mechanical strength, barrier, seal integrity and puncture resistance. Together they give protection that no single film can match.

The six-layer construction is used where the product is high value, the storage period is long, or the transport route exposes the shipment to long spells of heat and humidity.

Key features

  • 5-layer and 6-layer laminated constructions
  • Almost total barrier against moisture and atmospheric gases
  • High puncture and tear resistance
  • Reliable heat-seal integrity with very little permeation at the seal
  • Suited to long storage and long-haul export

How we build it

Layer counts are not a marketing number for us. Each layer is specified for a job, and we can explain what every layer does. We will walk your technical team through the structure, layer by layer, before you sample.

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.

  • 5 or 6 layers
  • Foil thickness
  • Nylon and polyester layer choice
  • Seal structure
  • Dimensions
  • Desiccant pockets

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.
