DuPont today announced its latest partnership to develop customized solutions for shipping and posting consumer and business packages. The company is working with India Post to create protective envelopes for its Speed Post and Insured Post services, the first such offerings in India.

Made of DuPont Tyvek brand protective material, a nonwoven innovation from DuPont, the envelopes provide security and protection for their contents. Tyvek has unique qualities including resistance to water, tears and abrasion, soft and smooth textures for printability, light weight and customized tamper-evident features.

DuPont Tyvek envelopes are used around the world by shipping companies and postal authorities, including the U.S. Postal Service and French La Post, among others. The lighter weight of Tyvek, as compared to paper products, helps lower operating costs by keeping mail volumes below weight thresholds and by assuring that mail arrives securely, wherever the destination.

“With the introduction of the new DuPont Tyvek speed post envelopes, customers will find it convenient to send documents and letters through Speed Post. We expect this to enhance growth for our Speed Post business, which currently deals with 1.7 crore (10.7 million) consignments per month and grew by about 30% last year,” said John Samuel, general manager—business development, India Post.
