Coating

What it means in packaging

Coatings can influence gloss, ink behaviour, scuff resistance or barrier properties. These are separate requirements: a glossy surface does not establish a moisture barrier or suitability for direct product contact.

A practical example

A carton may have an overall protective coating with a reserved glue area left untreated for reliable bonding.

What to check

Specify the required function and application area, and confirm compatibility with ink, adhesive and the packed product.

Use it in your project

• Choose board, caliper and finishes
• Place artwork and manage layers
