In business for almost 50 years, the company was created following its development of the Envopak, a secure and cost-effective alternative to single use envelopes for the two-way distribution of mail. Two years later it acquired Sealsfast Ltd, a manufacturer of security seals and became the Envopak Group, the UK’s biggest supplier of re-usable and tamper evident products. Today the Envopak and Envoseal product ranges are sold in more than 60 countries worldwide and are synonymous with superior product quality, customer service and continuous innovation. Their success led to their acquisition in 2002 by Illinois Tool Works Inc (ITW) and allowed a new company, ITW Envopak, to be born. The adoption of ITW’s 80/20 philosophy and the backing of its significant financial resources, will enable ITW Envopak to build on its sales, marketing and manufacturing expertise and expand its share of the global security marketplace.
