COSEAL 55-114

Coseal™ 55-114 is a waterborne system based on natural rubber latex developed for use in cold seal technology for flexible packaging applications. Target bond/cling performance at lower dry coating weight. Coseal 55-114 can be applied by both pattern and full coverage to obtain a dry film that can be sealed by pressure only to itself. Coseal 55-114 offers good adhesion and anchorage to a variety of plastic films used in flexible packaging. Coseal 55-114 is particularly recommended for untreated, pearlescent, and cavitated opaque BOPP-films and acrylic- and PVDC-coated films as well.
