Corrugated die cut inserts provide internal protection to products during shipping.
It’s a better option over inflatable packaging because it is paper-based and easily recyclable. The other advantage is the clean presentation it gives when opening the box.
Where traditional filling like bubble wrap creates a mess when taken out of the container, die cut inserts are assembled into one single piece, allowing a clean unboxing of the product.
However, they are not ideal for small production runs because the initial startup costs tend to be high.
