Avoiding Delamination in Flexible Packaging

In the world of flexible packaging, it is critically important to control the adhesives used to bond laminates such as films and foils, which require meticulous accuracy of blending, dispensing and applying adhesives to substrate materials. Yet, the adhesive controls required for such accuracy are missing from nearly all systems, even though the consequences are quite serious—packaging failure, product loss, and significant downtime.

If not applied in the correct coat weight, whether too light or too heavy, the lamination bonding will fail, causing the overlay to bubble, blister or otherwise delaminate from the base material, a scenario that worsens as the problematic packaging travels farther down the distribution chain.
