Pallet Interleavers for Load Stabilization and Protection
Pallet interleavers are paper or cardboard sheets placed between layers of products stacked on pallets. Their purpose is to separate layers, stabilize the load, level the surface and limit direct contact between products, cartons or packaging.
Pallet interleavers work well in warehousing, transport, picking, production and bulk packaging. The format, grammage and material should be selected based on the pallet type, product weight, number of layers, transport method and required protection level.
When to Choose Pallet Interleavers?
Pallet interleavers are worth using when products are stacked in layers and require separation, stabilization or surface protection.
Most common applications:
- separating product layers on pallets,
- stabilizing cartons and bulk packaging,
- limiting product shifting,
- protecting surfaces against scuffs,
- leveling layers on pallets,
- separating products in warehouses,
- preparing loads for transport,
- protecting products during picking and shipping.
Applications of Pallet Interleavers
| Application area | Example use | Key benefit |
|---|---|---|
| Warehouse | separating product layers | better load organization |
| Transport | stabilizing products on pallets | reduced shifting and damage |
| Production | interleavers between batches or layers | consistent product stacking |
| Logistics | preparing pallets for shipment | greater load stability |
| Bulk packaging | separating cartons and packaging | protection against scuffs |
| E-commerce and fulfillment | picking larger batches of goods | organized products on pallets |
| Technical industry | separating flat items or components | surface and edge protection |
Types of Pallet Interleavers
Interleavers can differ in material, grammage, stiffness, format and purpose. The choice depends on whether the interleaver is only to separate layers or also increase overall load stability.
| Type of interleaver | When to choose | Characteristics |
|---|---|---|
| Paper interleavers | light product and layer separation | economical and flexible |
| Cardboard interleavers | greater stiffness and stabilization | good for heavier products |
| Solid board interleavers | higher resistance and stiffness | for demanding applications |
| Testliner interleavers | packaging and technical applications | good balance of function and economy |
| Kraft interleavers | when paper strength matters | good for packaging and separation |
| Custom-sized interleavers | matching pallet, carton or product | reduced waste and better fit |
Grammage of Pallet Interleavers
The typical grammage range for pallet interleavers is 80-400 g/m². Lighter grammages work well for simple separation, while higher grammages should be considered for greater loads, more layers or higher stabilization requirements.
| Application range | When to consider | Function |
|---|---|---|
| Light interleavers | lightweight products, simple separation | layer separation and contact protection |
| Medium interleavers | standard cartons and product layers | separation and basic stabilization |
| Stiffer interleavers | heavier products or greater load | better support and layer leveling |
| 80-400 g/m² | range for various pallet applications | from light separation to stiffer interleaver |
How to Choose the Interleaver Format?
The interleaver format should be matched to the pallet dimensions, carton, product or layer arrangement. An interleaver that is too small will not stabilize the entire layer, while one that is too large can hinder packaging and generate unnecessary waste.
When selecting the format, consider:
-
Pallet type
The format can be matched to EUR pallets, industrial pallets or non-standard carriers. -
Product layer dimensions
The interleaver should correspond to the actual arrangement of cartons or products on the pallet. -
Interleaver function
A different format suffices for light separation, while a different one is needed for full layer support. -
Place of use
Interleavers can be used at the bottom of the pallet, between layers or as a top sheet. -
Work ergonomics
Sheets should be convenient for operators to retrieve, place and use. -
Packaging and storage
Interleavers can be supplied in stacks, packs or batches matched to the process.
Pallet Interleavers for Load Stabilization
Interleavers help level layers and limit product shifting. They are particularly useful when cartons or packaging have varying stiffness, slippery surfaces or require better support between layers.
Load stabilization matters for:
- pallet transport,
- multi-level warehousing,
- order picking,
- stacking bulk cartons,
- products with slippery surfaces,
- products prone to scuffs,
- pallets with many layers.
Pallet Interleavers for Product Protection
Interleavers create a separating layer between products, helping to limit scuffs, dirt and direct surface contact. Depending on the material, they can be used as simple paper protection or a stiffer protective element.
They work well for protecting:
- cartons,
- bulk packaging,
- flat products,
- lacquered products,
- technical items,
- products prone to scuffs,
- layers of goods on pallets.
Paper vs. Cardboard Interleavers
The choice between paper and cardboard interleavers depends on the load, required stiffness and interleaver function.
| Type of interleaver | When to choose | Main advantage |
|---|---|---|
| Paper interleaver | light separation, lower load, standard packaging | flexibility and economy |
| Cardboard interleaver | greater stiffness and layer stabilization | better product support |
| Solid board | higher protection and stabilization requirements | greater resistance and stiffness |
| Testliner | packaging applications, technical interleavers | practical separation material |
| Kraft | when greater paper strength is needed | good protective and packaging material |
Pallet Interleavers vs. Flat Inserts
Pallet interleavers and flat inserts may look similar but have different primary intents. Pallet interleavers are mainly for layer stacking on pallets, while flat inserts are more often used inside packaging, cartons or as stiffening elements.
| Product | Main function | When to choose |
|---|---|---|
| Pallet interleavers | layer separation and stabilization on pallets | transport, warehouse, palletization |
| Flat inserts | stiffening, separation or protection inside packaging | cartons, bulk packaging, product |
| Packing paper sheets | universal packaging and protection | simple separation, wrapping, protection |
| Cardboard sheets | stiffer protection and underlays | greater mechanical resistance |
Sheeting and Converting Capabilities
Pallet interleavers can be prepared in formats tailored to the customer’s process. Depending on material and availability, sheeting, cutting to format, stacking or batch preparation for specific workstations is possible.
