"This initiative will help us to enhance growth for the Speed Post business which currently deals with 1.7-crore consignments per month. This business grew by about 30 per cent last year," said India Post General Manager (Business Development) John Samuel here over the weekend.

Initially the envelopes would be available only through retail at the post offices. Later DuPont will offer customised "Tyvek" envelopes to India Post for its corporate customers. With the introduction of the new product, customers will find it convenient to send documents and letters through Speed Post, Mr. Samuel added.

According to DuPont India President and CEO Balvinder Kalsi, "This partnership with India Post is a testimony to DuPont's mission of offering science-based solutions that make lives better, safer and healthier."

The DuPont "Tyvek" speed post envelopes of A5 size will be sold at Rs.5 per envelope and will be available from any of the 290 Speed Post Centres in the national network, and across the 1,000-plus Speed Post Centres in the State network.

Tyvek envelopes are made from DuPont Tyvek protective material, a material so strong and durable it easily withstands the most gruelling conditions. These envelopes are used world over by postal authorities, including the US Postal Service, French La Post as well as leading courier companies like FedEx
