U profiles protect the full edge length with a channel fit, while L profiles reinforce outer corners and vertical edges. Many packs use U along edges plus L/caps on corners.
Paper-based U profiles are widely recyclable. Keep them clean/dry and remove non-paper components before recycling.
Measure edge thickness and choose a channel that grips without compressing the product. Consider length to cover vulnerable spans fully.
Yes—U profiles provide a safer bearing for straps, reducing cut-in. Fit profiles, lightly wrap, then apply straps to the recommended tension.
No—they protect perimeter edges. Use inner cushioning (e.g., bubble wrap or paper bubble) to absorb shocks.
Whenever corners are exposed to impacts or stacking loads. Pair U profiles with corner profiles for full perimeter defence.
