Rigid Cardboard Insert
The Rigid Cardboard Insert is manufactured with high-strength corrugated board and rigid cardboard materials, providing excellent load-bearing capacity, compression resistance, and internal structural reinforcement.
Customized thicknesses, shapes, and support structures can be developed according to product dimensions and packaging box layouts. By effectively filling internal gaps and stabilizing products inside the package, the insert helps reduce movement, vibration, and collision during transportation.
With reliable cushioning and shock-absorbing performance, the Rigid Cardboard Insert offers comprehensive protection against pressure damage, impact, and deformation throughout storage and shipping processes.
