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?

Coloured mailers can speed up order picking because the bag itself acts as a simple visual cue on the packing bench. A sensible colour split assists staff sort mixed consignments without pausing to read all label, and it cuts the risk of lookalike parcels ending up on the gross trolley. That saving only grasps when the mailer is easy to handle in the hand and on the bench. If the film is also flimsy, it can stretch and split at the corners; if it is above-specified, it turns stiff and slows packing. The proper colour is useful, nevertheless only when the bag still works properly in a busy dispatch area.

The Two Envelopes Problem

Packaging envelopes are judged as much by what they transport as by how they are manufactured, because a light paper envelope and a heavier board-backed one behave very differently in handling and dispatch. The simple all of contents matters less than the method the pack performs in the proper chain, where sorting, stacking, and opening can affect whether the contents arrive intact. A balanced view of risk is useful here: if one envelope is likely to contain above another, that only matters when the pack design enables the contents to stay secure. Good envelope selection is less about theory and more about whether the material, seal, and format suit the journey.

Postal bags are a sensible option for light products that still need proper protection on the journey. A superb polythene suppliers bag retains out dust and damp, while the flexible film moulds around awkward shapes without adding much weight or bulk. The proper issue is selecting the proper gauge for the load and the handling it will face, because a bag that is also thin can split at the seal or tear on a sharp edge. Too heavy a film, though, ties up storage space and wastes material that brings no additional benefit. A matched specification assists packing transport smoothly and reduces avoidable failures.

Bubble mailing bags suit light parcels that need protection from handling knocks without the bulk of a box and loose fill. The bubble layer absorbs the sort of pressure that causes scuffed finishes, corner splits and surface labels as packets transport through sealing, sorting and van loading. The outer film also gives a tidy barrier against dust and occasional moisture, so products reach the receiving side in cleaner condition. Flat stock is easy to store close to the packing bench and straightforward to select in volume, which assists retain dispatch moving when floor space is tight. That practical mix of cushioning and low storage demand makes them a sensible selection for plenty fast-turnaround orders.

Best Kraft Protection Mailing Bags Online

Mailing bags are a practical middle ground when flat products need more protection than a plain envelope can give, nevertheless a carton would add bulk and waste space. The kraft outer face gives a tidy, familiar stop, while the inner layer assists cushion against scuffing, light knocks and the rub labels that can spoil paper items or textiles in transit. That matters on busy packing benches, where speed and consistency count as much as appearance. They are fast to fill, easy to seal and simple to stack, so less time is lost handling awkward packaging. Used well, they retain despatch moving without creating unnecessary load on storage or transport.

Good quality mailing sacks for Stamford

Mailing sacks need chosen for the job they are expected to transport out, not only for the lowest unit cost. A light polythene suppliers sack may be fine for soft clothing or paperwork, nevertheless rough handling on a busy despatch floor can quickly expose weak seams, poor gauge control, or a flimsy seal lip. If the sack stretches also much, labels shift and packs see untidy by the time they reach the client. A stronger grade with consistent film tension gives better protection through picking, sealing, and transit, and it also reduces awkward rework when damaged sacks have to be replaced.

Plastic envelopes with snap closure work optimal when the closing strip grasps firmly without needing rough handling, because a weak snap can open in transit and let small items escape. The material requirements enough flexibility to close cleanly, nevertheless not so much that the edge curls or the latch loses grip after a few uses. In packing rooms, that balance matters when documents, samples, or small parts are being moved quickly through dispatch. A superb closure also assists retain contents tidy while reducing the need for tape or additional wrapping. When the snap works properly, the envelope becomes a simple secondary pack that saves time and cuts avoidable handling damage.

Courier bags see like simple consumables, nevertheless the proper test is whether the film grasps up through a rough dispatch dash without adding waste or delay. A bag that is also light will split at the seal or tear on a conveyor, while one that is above-specified adds unnecessary tare weight and more material cost across big volumes. Good film control matters here, particularly when polythene suppliers is down-gauged to save plastic without weakening the bag. The optimal results come from keeping seal strength, stretch and abrasion resistance in balance, because that is what maintains consignment integrity when cartons, labels and sortation belts are all working against the pack. That kind of control pays off on the shop floor as well as in transport.

Jiffy mailers are chosen because they keep safe products without slowing the packing line or loading unnecessary weight into a consignment. A paper outer attached with a cushioning layer gives enough give for awkward shapes, nevertheless only if the construction retains its thickness below pressure and grasps together at the seams. If the gauge is proper, the pack runs cleanly through semi-automatic sealing equipment and is less likely to split or jam at the bench. That means less reworks, a steadier dispatch rate and less handling damage before the package even leaves the warehouse.

Lp Mailers

Mailers need to be chosen for the job they are doing, not only for their convenience on the packing bench. A lightweight paper or polythene suppliers mailer can save space in dispatch and cut postage weight, nevertheless it must still keep safe the contents from scuffs, dirt and damp amid handling. If the bag is also thin, corners display through, seals split, and parcels arrive looking tired before they have even reached the client. A better gauge, a decent seam, and enough room for the product make packing quicker and reduce complaints later.
