Features & Benefits

What you can expect from us:

Low-Temperature Seal

Seals at a lower temperature than competitive alternatives, resulting in minimized risk of product damage and reduced ink degradation.

Line Speed

Dwell time is up to 20% less than other heat-seal coatings. So you can expect improved yields, throughput and decreased costs.

Structural Integrity

Its rigidity makes it perfect for fold-over, tamper-evident blister packaging. A polymer coating on the felt side offers a completely sealed surface. You can also expect excellent folding and scoring properties.

Product Uniformity

A smooth surface provides outstanding ink holdout and best-in-class consistency for optimal printability. Polymer coat-weight uniformity offers improved efficiencies and maximum throughput on high-speed forming and filling equipment.

Simplified Converting

Direct printing on the board eliminates the need to apply a heat-seal coating. This improves converting efficiency and reduces inventory costs.
