Layer Pad
A layer pad is a rigid or semi-rigid sheet placed between stacked layers of product on a pallet, inside a case, or between cartons to separate layers, distribute load, and prevent damage during storage or transit. Common materials include corrugated board, solid board, chipboard, and PP plastic, selected for compressive strength, moisture resistance, reusability, and compatibility with automated handling.
During pallet build-up on a manufacturing shop floor, layer pads are inserted at defined intervals to create stable, uniform stacks and protect product surfaces from abrasion, crush damage, or inter-layer contact. In beverage, food, and FMCG operations, pads between cans or bottles keep rows aligned, distribute top load evenly, and preserve pallet integrity through forklift handling, stretch wrapping, and transit. Automated systems rely on consistent pad size and weight so conveyors, palletizers, depalletizers, and robotic pick stations do not jam or misfeed. From an inventory perspective, layer pads are tracked as packaging consumables or returnable transport items by SKU, size, material grade, and reuse cycle to prevent shortages at packing lines and receiving bottlenecks. They also preserve unit load structure, keeping cartons intact and traceability labels readable, which reduces rework and product damage.
- Under-specified compressive strength: A pad that is too weak for stack height or top load bows and crushes, deforming lower layers, skewing cartons, and collapsing pallet stability during transit or warehouse movement.
- Wrong material in humid areas: Paperboard or chipboard pads lose stiffness when exposed to moisture, causing edge collapse, load shift, and damaged packaging; PP pads are preferred where moisture resistance matters.
- Mismatched automation dimensions: Inconsistent pad size or weight makes automated palletizers, depalletizers, or case openers jam and misfeed, slowing throughput and increasing handling damage.
When should a layer pad be specified instead of a divider or slip sheet?
Use a layer pad when the primary requirement is inter-layer load distribution and product protection; dividers are often used for lateral separation, while slip sheets are more associated with unit-load handling and pallet transfer.
What performance variables matter most in a layer pad specification?
The key variables are compressive strength, thickness, surface friction, moisture resistance, recyclability, and dimensional consistency.
Why are layer pads common in beverage can operations?
Beverage can stacks are dense, rigid, and vulnerable to scuffing, denting, and load shift, so layer pads help stabilize the load and distribute pressure evenly across multiple layers.
