Mitsui Chemicals in collaboration with Bilcare introduces Chemipearl XSP in India: It's a new high-performance heat seal coating using water based technology for pharmaceutical blister packaging
The process is designed to help converting companies reduce volatile organic compound (VOC) emissions and indirectly help pharmaceutical companies to reduce their carbon footprints by moving toward sustainable packaging. Chemipearl is a particulate aqueous dispersion made of fine particles of polyolefins, previously considered extremely difficult to disperse in water. When compared with widely used aqueous dispersion techniques, Chemipearl is unique in that it does not use emulsifying agents or organic solvents, according to Mitsui. Characteristics of polyolefins, such as mechanical, water-resistant, and chemical resistant properties, are retained intact, making the product suited in heat sealing for packaging. Solvent-based heat seal coatings, common in India for example, contain around 70-80 percent of organic solvent and most of the converting companies that produce coated aluminum lid foil release the solvent directly into the open air.
