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.

Did you know this about coloured mailers?

Postal bags need the proper balance of strength and light weight if they are to survive picking, packing and sorting without adding unnecessary postage cost. A bag that is also thin can split at the seams when filled with folded garments, printed material, small parts or boxed accessories, while one that is also heavy raises material use and shipping weight for no proper benefit. Self-seal glue has to grab cleanly first time, because a weak closure means lost contents, returns and awkward claim handling for dispatch teams. The better selection is the bag that closes reliably, carries the load without stretching badly and still transports through the mail without additional fuss.

Bubble mailing bags keep safe fragile e-commerce products because the padded lining takes the sting out of knocks that would flatten a plain envelope. The outer film stays light, so dispatch staff are not adding unnecessary weight to each consignment, while the smooth inside face lets small items slide in fast without catching on corners or closures. That matters in busy packing areas where speed must be balanced with care, because a tidy occupy and a firm seal reduce the chance of burst packs, scuffed products, or awkward repacking at the stop of a shift. Reliable presentation at the pack station normally saves trouble later in the transport chain.

Mailing bags need the proper balance of strength, size and sealing performance if parcels are going to leave the despatch area in one part. Grey polythene suppliers bags are broadly used because they fold flat, take up small warehouse space and resist scuffing better than paper-based outer packs in damp conditions. The proper issue is not only the material, nevertheless the gauge and the method the seal behaves below load, because a weak flap or poor adhesive can open once a package is squeezed on a conveyour or stacked in transit. Good stock control also matters, since oversised bags waste occupy material and make picking slower. A correctly chosen mailing bag cuts handling damage and retains secondary packing simpler.

Mailing sacks need to be chosen and closed with transport in mind, because a lightweight package that sees fine on the packing bench can still split or scuff once it transports through sorting and linehaul. A superb sack has enough gauge to resist puncture, decent seal quality at the closure, and a size that suits the contents without leaving also much slack for the load to shift. If the bag is overfilled, corners press hard on the film and handling damage becomes more likely. The proper specification retains the consignment tidy from dispatch to delivery and reduces avoidable claims.

Plastic envelopes with Velcro can solve a simple nevertheless normal packing problem: a closure that requirements to be opened and closed plenty times without splitting the bag or wearing out a flap. For warehouse use, that makes them useful for paperwork, samples, small parts, or returns that transport through several hands. The grasp is that the hook-and-loop strip has to be fixed properly, because weak bonding will fail before the film does. Film gauge, edge sealing, and the method the envelope is filled all affect how long it lasts, so a light-looking pack still requirements sensible specification and handling.

Courier bags. Sorry, bag content…

Courier bags are often judged by the job they have to do at the dispatch point, not by how they see on the shelf. When a bag fails, the problem is normally gross gauge, weak seals, or a closure that suits light paperwork nevertheless not a mixed consignment with sharp corners or movement inside. Good handling beginnings with picking the proper size so the contents sit flat without straining the seams, then checking that the adhesive strip grips properly after fast packing. If the bag is oversised, parcels slide around and select-face efficiency drops because additional null requirements filling or taping. A sound spec retains packing fast and reduces complaints later.

Jiffy mailers suit small, low-risk consignments because they combine low weight with enough surface protection to retain products clean and presentable in transit. The proper attraction on a packing bench is speed: a bag-style mailer folds easily, closes fast, and avoids the need for additional corrugated outers when the item inside is flat or light. That can assist with select-face efficiency and cut handling damage from overpacking. The material still requirements the proper gauge and seal quality, though, because a weak closure turns a tidy pack into a complaint at dispatch. When chosen for the proper stock, this sort of mailer retains fulfilment moving without adding unnecessary board or null-occupy.

Lp Mailers

LP mailers need the proper board strength and fold shape if a vinyl record is going to arrive flat and undamaged. A cruciform style works well because the panels wrap around the record pack neatly and give better edge protection than a loose sleeve or soft envelope. For single discs, the mailer must grasp the item snugly without crushing corners, while a pack for multiple records requirements enough depth and stiffness to stop the contents moving about in transit. Getting the fit proper reduces handling damage, cleaner packing lines, and pointless returns from clients who come by split seams or bent sleeves.

Where to Buy Plastic Envelopes for Organising

Plastic envelopes work well when documents, labels, or small flat items need to stay together and stay clean through handling. Their smooth surface resists moisture and scuffing better than plain paper wallets, which matters when files are moved between desks, vans, and storage shelves. In packing or dispatch areas, they also make it easier to separate paperwork for alternative jobs without bending corners or losing inserts. The main selection is normally between flimsy film and a sturdier gauge that grasps its shape. A properly specified envelope saves time when sorting mixed paperwork, and that makes daily organisation less messy.

Coloured mailers can make despatch work quicker because they give the packing bench a simple visual sorting system. When several gift spectrums or stock lines are being packed at the same time, a transparent colour selection assists staff lift the proper stack at once instead of reading labels on all bundle. That reduces mix-ups and retains order separation tidy, which matters on busy shift changes and in small packing areas. The earn is not only speed nevertheless less errours in secondary packing, so the finished consignment leaves in the proper sequence and reaches the dispatch lane cleanly.
