Postsafe superstrong polythene envelopes are manufactured to the highest quality standards in the UK. Polythene envelopes are strong, less expensive than paper envelopes and cardboard boxes, and the light weight reduces postage costs. All envelope products are weatherproof, tear resistant, and 100% recyclable. The flexible structure wraps around the envelope contents and saves space - simple to use with peel and seal closure. All our polythene envelopes are approved by Royal Mail.
