Returnable trays and dividers

PP twinsheet trays, PP corrugated dividers, foam inserts and racks, designed around your part to go round your loop for years.

Returnable trays and dividers

Packaging that comes back, trip after trip

For parts that move between the same plants every week, one-way cardboard is a cost you pay again and again. Returnable trays, dividers and racks hold every part in its own place, last for years, and cut waste and packing time.

Proteqpack Consulting designs each system around the part, the box and the loop. Proteqpack Supplies delivers it and keeps it running.

  • Each part in its own pocket or cell: no contact damage
  • Higher pack density and faster picking at the line
  • Less packaging waste, which helps with PPWR reuse targets

Returnable trays and dividers by material

Examples from our own projects. Every one of these is built to go round a loop many times, not to be thrown away after one trip.

Thermoformed trays and lids

PP twinsheet trays
PP twinsheet trays
Double-walled thermoformed PP

Formed from two PP sheets that are fused together, so the tray is hollow, stiff and light. Stacks in a pallet-sized system, takes years of loops and can be repaired and color-coded.

Used forGears, shafts and clutch parts for e-transmission lines, in series
Twinsheet nest trays

Full-contact pockets for long parts

Each part lies in its own formed pocket, so shafts never touch and the operator picks them in a fixed order.

Used forInput shafts and other long machined parts
Single-sheet thermoformed trays

PET, PS or HIPS

Thinner, lower-cost trays and blisters that nest when empty. A good fit for smaller parts and short loops.

Hold-down lids and pallet lids

Lids that clamp parts in place and close a tray stack or pallet, from 600 x 800 to 1200 x 800 mm.

Used forClutch hubs, differentials and full pallet loads

Dividers and compartments

Interlocking divider sets

Slotted PP corrugated walls that form a cell for each part. Washable, moisture-proof and much longer-lasting than cardboard. Available in conductive (ESD) and recycled PP.

Used forTurbochargers and pump housings
Dividers for Euronorm and KLT boxes
Dividers for Euronorm and KLT boxes
Inserts for standard returnable boxes

Divider sets made to fit the boxes you already pool, such as Euronorm and KLT containers, so the box stays and only the insert changes per part.

Punched sheets and grids

Punched PP sheets and grids that separate layers and hold parts in position. Sized to carry the weight of the layers above.

Used forGears and flanges stacked in layers
Foldable compartments

Flat for the return trip

Compartments that fold flat when empty, so the return transport takes far less space.

Foam, spacers and dunnage

PE foam inserts and sheets
Closed-cell cross-linked PE (XLPE)

Soft, clean foam that cushions finished surfaces and keeps its shape over many trips. Cut to plain sheets or with pockets.

HDPE, honeycomb and multiplex spacers
Rigid spacers and layer boards

Spacers made from HDPE sheet, PP or carton honeycomb, or multiplex (plywood), for strong separation between heavy layers.

Steel racks with dunnage
Racks with custom inserts

Steel racks fitted with foam or plastic dunnage, for heavy and bulky parts that travel in a closed loop.

Partitioned racks
Racks with PP or textile partitions

Racks divided into cells with PP or textile partitions, so each part is held separately and picked from the side.

Not sure which material fits?

Send a photo of the part and a few words on the route. We'll recommend what fits, and say so if you need less than you thought.
