Box, Crate and Industrial Bin Liners

Custom polyethylene liners for the inside of boxes, cartons, crates and industrial bins. Form-fit protection against dust, wood fibres and handling dirt when the primary container is rigid and the liner is the clean interface. Film thickness 25 to 300 microns.

What box and crate liners are for

A box liner or crate liner is a flexible polyethylene film liner made to the inside dimensions of a rigid container. The same product is often specified as a carton liner, bin liner, pallet box liner or export crate liner. The liner keeps product away from wood, cardboard dust and warehouse dirt. It is an inner layer, not a shipping container bulk system and not a slip-on pallet hood.

Dry bulk in a 20ft or 40ft container is a different product: container liners. Outer form-fit bags for items live on custom 3D bags.

How to measure

Take inside length, width and usable height. Decide whether the liner should sit fully inside or fold over the rim for sealing and cleanliness. Gusseted constructions help square corners. If the crate has battens or irregular walls, note them; a flat sheet number is not enough. Photos of the empty container help more than a brand name alone.

Most liner jobs start with polyethylene (PE). Anti-static and print options apply when the build allows. Food-contact claims only with documentation for that construction. Corrosion-sensitive metal packs should move to a VCI film conversation; moisture-sensitive sealed packs to barrier film. Chemistry detail lives on those format pages, not here.

Common questions

What is a box or crate liner?

A polyethylene liner that sits inside a box, carton, crate or industrial bin to protect contents from dust, wood fibres and handling dirt. Also called a carton liner, bin liner or pallet box liner.

How is this different from a container liner?

Box and crate liners fit secondary packaging interiors. A container liner lines a shipping container for dry bulk cargo. Different size family and different job.

How do I measure for a liner?

Measure inside length, width and usable height of the box, crate or bin. State whether the liner should drape over the rim or sit fully inside. Add a photo if the container has odd corners or lids.

What film thickness can you supply?

BENZ can supply film constructions from 25 to 300 microns, selected for product type, handling and whether the liner folds over the rim.

Can liners be food-grade?

Food-contact grades only when the exact film and construction are documented for that enquiry. Do not assume every industrial PE liner is food-grade.

VCI or barrier liners?

Corrosion-sensitive metal packs can use VCI film liners; moisture-sensitive sealed packs may use barrier film. Tell us the risk and we route to the right film family.

Need a liner for a real box size?

Send inside dimensions and what you pack. We will quote a PE liner and flag VCI or barrier if the risk needs it.
