DuPont Tyvek is not a paper. It's a smooth, non-woven mesh of 100% high-density polyethylene fibres

Tyvek envelopes will run on standard insertion and Inkjet printing machines, without special equipment

Unlike paper, Tyvek will not absorb moisture and fall apart. Nor will it tear, burst, fray or puncture, it's strong and tough. It resists all these hazards making it the perfect solution for important mail and storage

Mailing packaging made from DuPont Tyvek can produce less waste, use less energy and emit less CO2 than cardboard or low density polyethylene used in similar conditions
