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.
常见问题解答
Q: What thickness of protection board do I need?
标准瓶罐托盘码垛（饮料行业）适用厚度为3–4毫米；重型容器和桶装货物堆垛（工业用途）适用厚度为4–5毫米；极端载荷或托盘板作为层间主要结构元件的情况适用厚度为6–8毫米。如果您不确定，请联系我们，并提供您托盘的典型重量和产品类型，以便我们为您推荐合适的厚度。.
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?
是的。标准托盘尺寸：1,200×1,000 毫米（欧标）、1,200×800 毫米（英标）、1,000×800 毫米。 可提供定制尺寸——请在询价时注明您的托盘尺寸。定制尺寸的最低起订量为 200 件。.
Q: What is the minimum order quantity?
我们不设预先规定的最低起订量（MOQ）。我们的生产体系完全可扩展，能够高效支持从初期概念样品和试生产批次到大规模商业化生产等全流程，并能根据您的具体运营需求进行精准定制。.
