A versatile range of products for all bulky postal applications. Amongst this extensive range you will find tear resistant, recycled, coloured as well as the unique board back gusset setting apart the Blake range from all others on the market. These envelopes have a 25mm Gusset for bulkier mail and a handy peel and seal closure for quick and easy fastening. They are pocket opening - meaning they seal on their shorter side.
