Polyethylene, multilayer

A well-designed multilayer film can be thinner than the single-layer film it replaces and still be stronger, which brings the cost per liner down rather than up.

High oxygen barrier

EVOH barrier film

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

Almost total moisture and gas barrier

Aluminium laminate, 5 & 6 layer

Each layer is specified for a job: mechanical strength, barrier, seal integrity and puncture resistance. Most barrier failures happen at the seal rather than through the film.

Static dissipation

Conductive film

Gives static charge a controlled path away instead of letting it collect on the film surface. Supplied with a defined grounding arrangement where one is needed.

Static dissipation plus barrier

Conductive aluminium laminate

Combines both jobs in one construction, so a plant that would otherwise double-line can use a single liner.

Flexibility, clarity, chemical resistance

PVC film

Holds product groups that attack polyethylene. Stays soft across a wide temperature range and can be supplied clear so contents stay visible.

Heavy duty, reusable, waterproof

PVC-coated fabric

Built for years of repeated daily use rather than a single journey. Wipe clean, so it stays presentable in a working environment.

High tear strength, reusable, weatherproof

Woven laminated fabric

The woven base gives tear strength plain film cannot reach, and the lamination makes it weatherproof. UV stabilised grades available.

Total barrier, vacuumable, VCI compatible

Aluminium vacuum laminate

The vacuum process lowers oxygen inside the cover, holding back aerobic growth and stopping volatile components evaporating. Up to 6-layer with nylon and polyester.

Vapour corrosion inhibition

VCI film

Releases a vapour that settles on every metal surface inside the sealed cover, including internal bores the film never touches. Nothing to degrease afterwards.

Shrinks tight to shape, holds load as one unit

Heat-shrinkable film

Follows the shape closely instead of hanging loose, so there are no folds where water collects. Shrink ratio is matched to the load shape.
