Cardboard edge protectors (also called paperboard corner boards, angleboard, cornerboard, edge boards) are used to protect and reinforce the edges and corners of pallet loads so your product survives strapping, stretch wrap, forklifts, and the bumpy reality of shipping.
They’re not “extra.” They’re the cheap little piece of armor that prevents the expensive problems.
Here’s exactly what they’re used for — in the real world.
1) Prevent Straps From Cutting or Crushing Cartons
Straps concentrate a ton of force on a small corner. That’s how you get:
-
crushed top corners
-
strap dents and “strap lines”
-
torn corrugated under the strap
-
slack straps later because the corner collapsed
Edge protectors spread that strap pressure across a wider surface area, so the carton corners don’t buckle.
If you strap pallets of cartons and you’re not using edge protection, you’re basically accepting preventable damage.
2) Prevent Stretch Wrap From Crushing Corners
Tight stretch wrap is great… until it caves in the corners of the load.
On tall pallets, wrap tension can compress cartons and make the load “hourglass” inward. Edge protectors create stiff vertical edges so the wrap can pull tight without crushing the corners.
This is one of the biggest reasons edge protectors are used on retail and case goods.
3) Add Rigidity to Tall Pallet Loads (Stops Leaning/Racking)
Tall pallets love to lean.
Edge protectors act like vertical “spines” on the corners. They help:
-
keep the pallet square
-
reduce racking during transport
-
improve stack strength
-
keep loads looking clean at delivery
If you’ve ever watched a tall pallet tilt slightly when the forklift turns… you already know why this matters.
4) Protect Edges From Forklift and Handling Damage
Dock life is violent.
Forklifts bump pallets. Pallets scrape. Loads shift. Edges take hits.
Edge protectors absorb a lot of that damage so your product packaging doesn’t.
5) Reduce Damage Claims and Chargebacks
This is the money reason.
Edge protectors reduce:
-
corner crush
-
scuffing
-
strap damage
-
wrap damage
-
load shifting
That means fewer:
-
returns
-
rework
-
chargebacks
-
“packaging inadequate” complaints
They’re one of the cheapest claim-prevention tools you can buy.
6) Improve Load Containment When Used With Top Sheets / Slip Sheets
Edge protectors work even better when paired with:
-
top caps / top sheets (corrugated pads, chipboard)
-
proper strapping patterns
-
proper wrap containment
The sheet spreads strap force across the top layer. The edge protectors reinforce the corners. Together they stop the two most common pallet failures: crushed corners and loose straps.
7) Protect Finished Surfaces (Not Just Cartons)
Cardboard edge protectors can also be used to protect edges of:
-
furniture
-
doors
-
panels
-
fabricated parts
-
products with painted/coated edges
Anytime you don’t want strap or rub damage on an edge, they help.

Quick “When Should I Use Them?” Checklist
Use cardboard edge protectors if any of these are true:
-
straps are denting or cutting cartons
-
stretch wrap is crushing corners
-
pallets are tall/top-heavy
-
shipping LTL or long-haul
-
multiple transfers/rough handling
-
product packaging must look clean at delivery
-
you’ve had corner-related damage claims
If straps touch corners and you care about the shipment arriving clean, edge protectors should be standard.
Bottom Line
Cardboard edge protectors are used to protect pallet edges from strapping, stretch wrap, and handling damage, while reinforcing loads to reduce shifting and corner crush. They spread pressure, add rigidity, and dramatically reduce damaged shipments and claims.
