PP Protection Board — The Layer Between Your Product and Pallet Damage
Every pallet in a warehouse or truck carries a stack of products that exert downward pressure. The item at the bottom of the stack bears the combined weight of everything above it — plus the dynamic shock of forklift handling, transport vibration, and pallet racking. Without a protection board between layers, that pressure concentrates on the product itself: bottle caps crush, can rims deform, oil drums dent, and stacked boxes collapse unevenly.
PPBOXY’s PP protection board is a twin-wall corrugated polypropylene sheet engineered to distribute this stacking load evenly across the pallet surface. Placed between product layers during palletizing, the board spreads the downward force, preventing point-load damage to individual items. The waterproof PP material maintains its load-bearing properties in wet, humid, and cold conditions — unlike cardboard, which softens and collapses when exposed to moisture.

Applications
Beverage & Bottle Logistics
Bottle caps, glass necks, and can rims are the most vulnerable points in a palletized beverage load. A PP protection board between each layer of bottles distributes the weight of the layer above across the full surface — eliminating the point-load pressure that crushes caps, chips glass necks, and dents can rims. The waterproof board tolerates condensation from cold-filled bottles and outdoor storage without softening.
Oil Drum & Industrial Container Stacking
Steel and plastic drums are designed for stacking, but uneven weight distribution deforms drum tops and compromises sealing. A PP protection board placed between stacked drums distributes load evenly and prevents metal-to-metal contact that causes paint damage and rust initiation points.
General Pallet Load Stabilization
Mixed-load pallets — different box sizes, irregular shapes, varying weights — are inherently unstable. A PP protection board between product layers creates a flat, rigid surface that stabilizes the load, reduces lean during transport, and prevents upper-layer items from settling into gaps between lower-layer items.
Export & Container Shipping
Ocean containers experience six degrees of motion during transit. Stacked product layers shift, rub, and compress. PP protection boards between layers absorb this movement, reduce friction damage (scuffing, label wear), and maintain pallet integrity from factory to destination port. ISPM-15 exemption applies — no wood treatment required.
الأسئلة الشائعة
Q: What thickness of protection board do I need?
3–4 mm for standard bottle and can palletizing (beverage industry). 4–5 mm for heavy container and drum stacking (industrial). 6–8 mm for extreme loads or where the board is the primary structural element between layers. If you are unsure, contact us with your typical pallet weight and product type for a thickness recommendation.
Q: How is this different from a layer pad?
A protection board and a layer pad serve the same function — load distribution between product layers on a pallet. “Protection board” is the broader term; “layer pad” typically refers to the specific application in bottle/can palletizing. PPBOXY’s product pages differentiate them by application context — this page covers general stacking protection; Layer Pads & Dividers → covers bottle-specific pallet layer pads and dividers.
Q: Will the board absorb moisture from cold-filled bottles or outdoor storage?
No. PP absorbs less than 0.01% water. Condensation from cold-filled beverage bottles, rain during outdoor storage, and humidity in refrigerated warehouses have zero effect on the board’s load-bearing capacity. Cardboard layer pads under the same conditions lose 40–60% of their compression strength within hours.
Q: Can the boards be cut to a custom pallet size?
Yes. Standard pallet footprints: 1,200×1,000 mm (Euro), 1,200×800 mm (UK), 1,000×800 mm. Custom dimensions are available — specify your pallet size when requesting a quotation. MOQ for custom sizes: 200 units.
Q: What is the minimum order quantity?
We operate without a predefined MOQ. Our production framework is fully scalable, allowing us to efficiently support everything from initial concept samples and pilot batches to high-volume commercial manufacturing, tailored precisely to your operational requirements.
