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.

Grey Mailing Bags Strong Poly Postal Postage Post Mail Self Seal All Sizes Cheap Grey Mailing - £151.99

Grey mailing bags work optimal when the job calls for light, tidy and low-cost outer packaging rather than a heavy box. A superb poly mailing bag saves board, cuts pack time and takes up far less space at despatch, which assists when orders are being picked fast and consignment volumes change through the day. The film requirements the proper gauge for the load, though, because a flimsy bag can split on a sharp edge or at a badly folded seam. A proper self-seal strip also assists retain closure quality consistent across the packing bench. When the bag matches the contents and handling route, damage risk drops and secondary packing becomes less of a nuisance.

Mailing sacks suit organizations that need a simple, tidy method to send grouped items, particularly when parcels and big letters are being processed through an online mailing record. A well-chosen sack retains pre-sorted mail together, makes dispatch easier, and gives staff a cleaner handover at the counter or assortment point. The main point is to match the sack to the load and the route, because weak material or poor closure can lead to split seams, loss of contents, and wasted time chasing missing items. When the pack size and gauge are proper, transport is smoother and the all mailing job runs with less handling damage and less rework.

Plastic envelopes are a useful option when papers need to stay together without becoming battered in transit or in a busy filing area. A soft polythene suppliers or polypropylene body gives better moisture resistance than plain paper, so invoices, instruction sheets and dispatch notes are less likely to curl or tear if handled repeatedly. The closure matters as much as the material, because a poor flap or weak fastening can let contents creep out amid picking, sorting or storage. In practical terms, they suit short-life documents, sample packs and internal transports where fast access is more useful than archive strength, and that means less damaged sets and less time spent replacing missing sheets.

Briefcase Style Courier Bags

Briefcase style courier bags suit lighter loads where a tidy, professional appearance matters as much as basic protection. The nylon building retains the bag low in weight, so it does not add much to the consignment, yet it still gives better resistance to scuffing than a plain film mailer. A 22W x 16H x 6D shape leaves room for documents, files or compact samples without forcing the contents flat, which assists avoid corner damage and bent edges. The briefcase form also makes handling easier at the picking bench and on the receiving side, because the load sits neatly and is less likely to shift. For short trips and office deliveries, that balance of lightness and control makes the format a sensible selection.

Jiffy mailers suit light, low-risk products because they cut out the empty space and dead weight of a carton. For products that are flat, compact, and not easily crushed, a padded mailer or robust polythene suppliers mailer can trim package weight and reduce the amount of secondary packing needed. That brings knock-on earns in dispatch speed, storage space, and carrier surcharges, particularly when thousands of small consignments transport through the same packing line. The drawback is transparent as well: if the products need stacking protection or have sharp edges, a mailer can lead to handling damage and complaints. A superb packing decision beginnings with the product, not the carton.

Professional mailers are a practical method to keep safe products while keeping packing speed high. A well-chosen mailer can reduce the need for outer cartons, cut down on secondary packing, and make dispatch faster where light items transport in volume. The material matters because film strength, seal quality, and puncture resistance all affect whether a package arrives intact after sorting, stacking, and transport. Board-backed and padded styles suit alternative product shapes, while plain polythene suppliers versions can assist retain weight low and storage simple. Stock control is easier when mailers are held in tidy spectrums by size and gauge, since select-face efficiency and the proper fit reduce handling damage. The optimal result is a mailer that protects the item without wasting space, materials, or labour.

Clear Plastic Envelopes Velcro Closure

Plastic envelopes work well when the job requirements a tidy, light cover that lets the contents stay visible without adding much bulk. For paperwork, samples, or small flat items, the transparent film makes checking and sorting quicker on the packing bench and in dispatch, particularly when staff need to spot a code or insert without opening the pack. The proper issue is selecting a gauge that gives enough toughness without turning the envelope stiff or awkward to handle, because thin film can split and thicker film can slow filling. Used with sensible folding and storage, they assist retain secondary packing tidy and reduce needless handling damage.

Coloured mailers sit in a rather more technical corner of fulfilment than the list of products language recommends. The useful distinction is not merely visual identification on the despatch bench, nevertheless how a lightweight polythene suppliers structure can be tuned to grasp line speed without inviting split rates, static cling or needless tare weight across a high-volume consignment profile. Gauge discipline matters here: also lean, and seal integrity suffers once corners of boxed stock start working against the film amid sortation; also heavy, and volumetric efficiency is undermined for no meaningful earn in pallet stability or outbound handling. Where the film is manufactured with consistent melt-flow properties and a sensible balance between toughness and flex-crack resistance, coloured mailers can assist clean select-face efficiency while reducing the need for secondary bagging. There is also a quiet circular-economy argument in favour of a well-specified mono-material formatprovided pigments and adhesives do not compromise the recovery streambecause lower material mass per unit and more predictable recyclability tend to improve amortised energy performance above the life of the pack. The operational value, then, lies less in the fact of six alternative sizes and more in the warehouse reality that size discipline, seal performance and manageable surface behaviour combine to retain packing stations moving without swelling damaged-stock returns.

Wide spectrum of envelopes sizes and styles

Envelopes manufactured on-site give tighter control above quality, lead times, and consistency from the first cut to last pack-out. When production happens in one place, board grade or paper selection can be checked against the job spec before a dash beginnings, and gauge, glue line, or seal quality can be monitored without waiting for third-party feedback. That matters in dispatch because envelopes need to meet size tolerances cleanly, stack well in cartons, and arrive prepared for print, filling, or mailing without curled flaps or weak seams. Local manufacture also makes short runs and repeat orders easier to manage, which assists stock rotation and reduces the risk of holding the gross format in the warehouse. The practical result is less handling problems and a more proper supply.

Bubble lined mailing bags give light dispatch items a better chance of arriving in one part, particularly when the contents can be scuffed, bent or knocked about in transit. The outer layer requirements enough strength to resist tearing at the seal and along the base, while the bubble lining takes the edge off impact and surface abrasion. White outer film also gives a cleaner presentation for mail order work, where first impressions still matter when the package is opened. The K/7 size suits compact products that need more protection than a plain mailing sack can offer. For packing lines and despatch teams, that combination saves time and cuts avoidable handling damage.
