Application for Pharmaceutical packaging with Chemipearl XSP

Mitsui Chemicals, Inc. (TOKYO: 4183; President&CEO: Tsutomu Tannowa) announced the successful development of XSP series of Chemipearl which is a high performance “Water-based Heat Seal Coating” for pharmaceutical blister packaging. Chemipearl XSP will provide an environment friendly alternative for existing solvent based heat seal coatings, which contain around 70-80% of organic solvent. In India, most of the converting companies which produce coated aluminum lid foil release the solvent directly to open air, causing environment pollution. Chemipearl XSP will help converting companies to reduce the VOCs (Volatile Organic Compounds) emission significantly and indirectly help pharmaceutical companies to reduce their carbon footprints and move towards sustainable packaging for a better society.

Bilcare Limited, India’s leading innovation-driven technology solution company has been associated with Mitsui Chemicals to develop this application. Applying this innovative technology by Mitsui Chemicals, Bilcare aims to provide Al foils coated with water based heat seal coating under the brand name “Zeon Aqua to global pharmaceutical packaging industry for the PTP blister packaging application. Working together Mitsui Chemicals and Bilcare are committed to provide value added products to global pharmaceutical industry. Bilcare will display “Zeon Aqua” at CPhI India during 28-30 November at Bombay Exhibition Centre, Goregaon, Mumbai, India.

Chemipearl XSP based Al foil has been welcomed by Indian pharmaceutical companies. Its stability tests are ongoing at major pharmaceutical companies of India.

About Chemipearl XSP:

  • High ultimate seal strength at lower coating weight
  • Excellent mechanical, water-resistant, and chemical resistant properties
