IML or PSA? The Packaging Showdown That Every Brand Manager Needs to See!

When designing plastic packaging, one critical decision is label technology: in-mould (IML) or self-adhesive (PSA)? IML labels become part of the container itself, offering extraordinary resistance to moisture, abrasion, and chemicals—perfect for ice cream tubs, detergent bottles, and products exposed to harsh environments. They also enable 360-degree decoration and eliminate label application steps in filling lines. Self-adhesive labels, on the other hand, offer greater flexibility for short runs, frequent design changes, and application to pre-formed containers of various shapes.
