What are inserts (callage)?

“Callage” (also written as “calage”) is the French term for securing or filling a product within packaging. It refers to all cardboard components that are not the box itself, but ensure the product remains safe and immobile inside the box.

Examples of inserts:

  • Inserts that hold a bottle or vial
  • Dividers that separate multiple products from each other
  • Die-cut inserts that precisely follow the shape of your product
  • Internal corner protectors
  • Spacers filler sheets that take up the space between the product and the box wall
  • Honeycomb paper provides shock absorption and prevents scratches or damage to your items.

Why choose cardboard void fill material?

More sustainable than foam or plastic

Honeycomb paper and cardboard is a smart and eco-friendly packaging solution to protect products safely during transport. Furthermore, it is 100% recyclable. The customer can dispose of it in the paper bin along with the box, eliminating the need for a separate waste stream.

Customizable to any shape

Using cutting dies, we can produce inserts in the exact shape your product requires. From a simple L-profile to a complex die-cut insert with multiple compartments.

Can be combined with printing

Inserts that the customer sees upon opening the box can be printed with your brand, a welcome message, or product information. This allows you to utilize every inch of the packaging.

Shock-absorbing and scratch protection

Honeycomb paper offers excellent shock absorption and prevents scratches or damage to your items. Ideal for companies looking to optimize their packaging process with a sustainable and efficient solution.

Cost

Cardboard inserts are more cost-effective than foam or molded pulp for larger volumes. Additionally, end-of-life processing costs are lower.
