Best Practices with Paperboard Layer Pads and Stiffeners

In today’s fast-paced supply chains, products face countless hazards during shipping, from rough handling and sudden stops to stacking pressure and vibration. Even minor shifts can lead to dents, scratches, crushed corners, or complete returns. The good news? Simple, cost-effective paperboard solutions like layer pads, stiffeners, and slip sheets can dramatically reduce damage while supporting your sustainability goals.

At Hammond Paper, we’ve helped manufacturers and distributors across Canada minimize transit damage for over 30 years with high-quality recycled paperboard products. Here’s how to protect your goods effectively using these unsung heroes of palletized shipping.

Why Load Shifting and Damage Happen, And Why It’s Costly

During transport, pallets endure acceleration, braking, turns, and uneven roads. Without proper separation and reinforcement:

• Boxes or bags slide and collide.
• Lower layers bear uneven weight, leading to crushing.
• Sharp pallet surfaces or nails puncture products.
• Edges and corners get compressed or torn.

The result? Higher damage claims, increased returns, dissatisfied customers, and wasted resources. Studies and real-world experience show that poor load stability can contribute to significant losses, but targeted paperboard interventions can cut these risks substantially.

The Role of Paperboard Layer Pads

Layer pads (also called tier sheets or pallet liners) are flat sheets of chipboard, corrugated, or linerboard placed between layers of stacked products or between the pallet and the bottom layer.

Key benefits include:

• Even weight distribution — They prevent crushing by spreading compressive forces across the entire layer, protecting fragile or heavy items like bottles, cans, or boxed goods.
• Separation and cushioning — Ideal for products with uneven surfaces, layer pads reduce direct contact and absorb minor shocks.
• Clean barrier — They shield goods from pallet dirt, splinters, nails, or moisture, keeping your products presentable and compliant (especially important in food, cosmetics, and electronics).

Best practice: Use thicker calipers (e.g., 20–60 point) for heavier loads and corrugated options for added rigidity and shock absorption. Place a pad on the pallet base, between every 2–4 layers depending on product height and weight, and on top for extra protection.

Stiffeners and Edge Protectors for Added Strength

Stiffeners and edge protectors (also known as corner boards or U-channels) reinforce vulnerable areas:

• Stiffeners add rigidity to large or flexible packaging, preventing bowing or collapse under stack pressure.
• Edge protectors shield corners and edges from strapping damage, forklift impacts, and compression when pallets are double-stacked.

Best practice: Combine them with layer pads for a complete system. Apply edge protectors vertically along all four corners, then secure the entire load with stretch wrap or strapping. This creates a rigid “frame” that maintains stability even during aggressive handling.

Slip Sheets: The Stability Booster

Anti-slip sheets and standard slip sheets take protection further by increasing friction between layers or anchoring the load to the pallet.

• They prevent shifting of slippery items like bagged goods, cartons, or smooth boxes.
• High-friction versions can withstand significant angles of slide, keeping loads secure through turns and stops.
• They’re lightweight, space-efficient, and far more sustainable than plastic alternatives.

Best practice: Insert anti-slip sheets between layers for top-heavy or unstable loads. For maximum effect, test your specific configuration — many clients report up to 30% fewer damage claims when combining slip sheets with proper wrapping.

7 Practical Best Practices for Damage-Free Shipping

1. Assess Your Load — Evaluate product weight, shape, fragility, and stacking height. Heavier or uneven loads need thicker pads and more reinforcement.
2. Distribute Weight Evenly — Center the load on the pallet and alternate orientations if possible to improve interlocking.
3. Choose the Right Material & Caliper — Recycled chipboard or corrugated for most applications; moisture-resistant options for humid or refrigerated transport.
4. Layer Strategically — Use layer pads at the base, between layers (every 1–3 feet of height), and on top.
5. Reinforce Edges & Corners — Apply edge protectors and stiffeners where pressure concentrates.
6. Secure the Load — Combine paperboard solutions with stretch wrap, strapping, or banding. Avoid over-tightening that could crush edges.
7. Test and Train — Perform vibration, drop, and compression tests on sample pallets. Train warehouse staff on consistent placement for repeatable results.

Why Choose Recycled Paperboard from Hammond Paper?

Unlike plastic alternatives, our 100% recycled and recyclable paperboard layer pads, slip sheets, stiffeners, and edge protectors:

• Reduce your carbon footprint and support circular economy goals.
