Slip Sheets, Layer Pads, and Edge Protectors: How Paperboard Solutions Protect Products in Shipping and Warehousing

Published on Mon, Aug 10, 2026 12:00 PM GMT

In today’s high-volume shipping and warehousing environments, products face constant risks, vibration, shifting loads, stacking pressure, forklift impacts, protruding nails on pallets, moisture, and rough handling. Damaged goods lead to costly claims, returns, and dissatisfied customers.

Fortunately, three simple yet highly effective paperboard solutions, slip sheets, layer pads, and edge protectors deliver reliable protection without adding significant weight, bulk, or cost. Made primarily from recycled materials, these products help businesses stabilize loads, prevent damage, and support sustainability goals.

At Hammond Paper, we’ve supplied these essential paperboard items to North American companies for over 30 years. Here’s a practical guide to understanding each product, its benefits, and how they work together to safeguard your shipments.

What Are Slip Sheets and Layer Pads?

Slip sheets (also called skid liners, pallet liners, or push/pull sheets) and layer pads (also known as tier sheets or pallet toppers) are flat sheets of chipboard, corrugated cardboard, or linerboard. They are typically placed:

  • Directly on the pallet to create a clean, protective barrier
  • Between layers of stacked products
  • On top of a completed load as a protective cover

Hammond Paper stocks these in a range of calipers (commonly from about 0.009” / 9 point up to 0.060” / 60 point) and can supply standard or custom sizes. Many options are made from 100% recycled and 100% recyclable materials. Anti-slip sheets versions are also available for extra load stability.

Key functions include:

  • Shielding products from puncture by nails, splinters, or open pallet boards
  • Providing a clean, dry barrier between the product and the pallet
  • Reducing product shifting during transit
  • Distributing weight more evenly across stacked layers
  • Helping stabilize loads so less stretch wrap or secondary packaging may be needed

These sheets are especially valuable for bagged goods, cartons, bottles, printed materials, and mixed loads.

Benefits of Slip Sheets and Layer Pads

Businesses choose paperboard slip sheets and layer pads for both performance and practicality:

  • Damage reduction — They act as a protective buffer that significantly lowers the risk of tears, punctures, scuffs, and contamination.
  • Load stability — Proper placement between layers helps prevent shifting, reducing the chance of toppled or crushed product.
  • Cost efficiency — Lightweight and relatively inexpensive compared with thicker alternatives or plastic options, they lower overall packaging and freight costs.
  • Space and weight savings — Thin profiles take up minimal room and add little weight, supporting higher stacking density and lower dimensional weight charges.
  • Sustainability — Made largely from recycled fibre and fully recyclable, they support circular-economy goals and help reduce reliance on non-recyclable materials.
  • Versatility — Suitable for a wide range of industries including print, manufacturing, food packaging, retail distribution, and e-commerce.
  • Regulatory and cleanliness advantages — They help meet shipping standards and keep products cleaner during storage and transport.

When used correctly (for example, one sheet on the pallet base, additional sheets every few layers depending on product weight and height, and a top sheet), they form a simple but highly effective protection system.

Understanding Edge Protectors

Edge protectors (also called corner boards, U-channel boards, or edge guards) are rigid paperboard or laminated board pieces designed to fit over the vertical edges and corners of palletized loads. They are commonly made from recycled paperboard and can be supplied in various lengths, thicknesses, and configurations.

These protectors are applied along the four corners (and sometimes additional edges) of a stacked load before stretch wrapping or strapping.

Benefits of Edge Protectors

Edge protectors address the vulnerable pressure points of any palletized shipment:

  • Crush and impact resistance — They distribute stacking and strapping pressure away from carton edges, helping prevent crushing, denting, or splitting.
  • Protection from handling damage — Forklift tines, pallet jacks, and warehouse equipment frequently strike corners; edge protectors absorb much of that impact.
  • Improved load integrity — By reinforcing the outer frame of the load, they reduce shifting and maintain a more stable, square stack during transit.
  • Professional appearance — Clean, protected edges present a more polished look to customers and reduce the chance of ragged or damaged packaging arriving at destination.
  • Compatibility with other packaging — They work seamlessly with stretch wrap, strapping, and the slip sheets/layer pads described above.
  • Eco-friendly profile — Paperboard edge protectors are recyclable and align with sustainability initiatives.

Industry experience and studies consistently show that proper use of edge protectors can meaningfully reduce edge-related damage claims.

How Slip Sheets, Layer Pads, and Edge Protectors Work Together

The real power comes from combining these products into a complete protection system:

  1. Place a slip sheet or layer pad on the empty pallet to create a clean base.
  2. Stack product layers, inserting additional layer pads at regular intervals for weight distribution and separation.
  3. Apply edge protectors vertically along all four corners (and any long sides that need reinforcement).
  4. Secure the entire load with stretch wrap or strapping.
  5. Optionally add a top layer pad or pallet topper for extra moisture and impact protection.

This layered approach stabilizes the load, protects both the bottom and the edges, and helps products arrive in better condition, even under demanding shipping conditions.
