About Us

For more information on the courier bags, mailing envelopes and mail order bags that we stock or can manufacture for you, please see our mail order bags section.

We were established in 1961 by Mr Geoffrey Davies who purchased a bag making machine advertised in the local paper and sold door to door. As sales grew, Geoffrey Davies teamed up with college friend Brian Turner who became in charge of production and the business moved firstly to a lock-up garage and then on to larger factory premises in Alperton, West London.

After some consolidation, we now have a new management team headed by Jon Lomax and are looking to continue Polybags' development and success. Business is expanding again. Improvements are being made and after taking on the business of Chapel Polythene in 2005 we are now very tight for space and have committed to extending into next door at the end of this year.

Plastic envelopes work optimal when the job requirements light protection, fast handling, and a tidy stop without the weight of a box. The hook-and-loop closure gives repeated opening and closing without the flap tearing away as fast as a weak peel seal might, so the contents stay secure amid stock checks, returns, or internal transport.

The proper value sits in production-minded equipment that retains running with minimal fuss, because dispatch areas lose time fast when sizing, sealing or feeding becomes erratic.
