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?

Jiffy mailers manufactured with recycled newspaper inside and recycled kraft outside cut away a lot of unnecessary material without giving up proper protection. The lighter build assists reduce postage and makes packs easier to handle on the shop floor, while the smaller carton and bag size also frees up space in storage and on picking bays. Using normal kraft instead of dyed stock avoids another processing step and gives the mailer a simpler recycling route because it can proceed with mixed paper. That sort of specification suits despatch teams that need a protective pack which is still straightforward to sort and dispose of after use.

Mailers work well when the job is to send light products fast without tying up space or money in heavier packaging. A sensible mailer gives enough protection for folded textiles, paperwork, sample packs, or other low-risk items while keeping secondary packing simple and fast. In the warehouse, that means easier select-face handling, less labour at dispatch, and less dead weight moving through the system. The proper value comes from matching gauge, seal quality, and closure to the product rather than overpacking it. A mailer chosen properly cuts waste and retains the dispatch line moving without adding unnecessary cost.

Jam Paper 9 3/4'' x 14 1/2'' 6pk Plastic Envelopes with Snap Closure, Legal Booklet - Multicolour, Multi-Colored

Plastic envelopes are a practical selection when papers need protection from scuffs, damp and fast handling in a busy setting. A snap closure gives a firmer grasp than a loose flap, so sheets are less likely to slip out in transit or amid sorting on a desk, and the larger legal-booklet size suits bundles that would crease in smaller wallets. Multicoloured packs can also assist with stock separation, because alternative colours make types easier to spot at a glance. For offices, schools and dispatch areas, that can save time and cut mix-ups. The main point is that a simple closure and sensible sizing often do more useful work than a fancier-looking folder.

#4 Glassine Envelopes – #HS204

Glassine envelopes work well when a pack requirements a clean, smooth sleeve that will not grab or scuff the contents. The semi-translucent paper gives enough visibility for checking the item fast, yet still offers a tidy barrier for paperwork, cards, samples, or flat shopping parts. Because glassine has a tight fibre structure, it folds sharply and feeds reliably through packing lines, which assists retain hand packing tidy and tidy. It also suits secondary packing where light protection matters above heavy-duty strength. When the specification is matched to the job, glassine gives a clever stop without wasting material.

Postal bags are a tricky substrate when the aim is to turn reused material into something fresh without losing the character that makes it fascinating. Old sacks and mail bags can transport wear, staining and strange fibres, so the print process has to work with an uneven surface rather than a clean sheet. That means selecting inks, curing and pressure settings that grasp detail without bleeding into weak spots or flattening the texture. The optimal results come when the material is treated as a feature, not a flaw, because the history shows through the finished part and adds value. Good production judgement retains the print legible while preserving the bag's unique feel.

Bubble mailing bags give semi-fragile products a better balance of protection and packing efficiency than either plain mailers or small cartons. The bubble layer cushions knocks and reduces edge damage, while the outer film retains weight down and avoids the wasted cube space that can come with corrugated board on light consignments. That makes them a sensible selection for mixed lines like prints, jewellery, small tools and decorative fittings, where a full box would add handling time without adding much value. A superb bag still relies on clean converting: proper bubble height, even film gauge and a peel-and-seal strip that grasps below rushed packing bench conditions. When those properties are controlled properly, transit performance and select-face efficiency both improve.

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

Mailing bags work optimal when the gauge, seal and size are matched to the products being sent. A thin bag may save material, nevertheless it can split at the corner, scuff the contents, or burst if a package is overfilled and dragged across a sorting bench. Grey polythene suppliers is normal because it conceals the contents and copes well with normal handling, while a superb seal assists stop tampering and retains loose items tidy amid despatch. The proper size also matters, since a bag that is also big wastes film and leaves the consignment shifting around. A properly chosen mailing bag gives safer transit and less returns from damaged products.

Why are mailing sacks superb packaging for posting non-fragile products?

Mailing sacks earn their place when online order volumes jump and dispatch teams need to transport parcels fast without tying up scarce packing time. Their value lies in speed and handling rather than presentation, because a simple sack can be filled, sealed, and sent with far less effort than a rigid box. That makes them well suited to peak trading, when select-face efficiency and fast secondary packing matter above like packaging. If the sack gauge and seal are proper for the products, turnaround stays brisk and damage stays low. A well-chosen sack retains the dispatch line moving when all small counts.

Plastic envelopes work well when documents need light protection and fast handling, nevertheless the closure style determines how proper they are in proper use. A hook-and-loop flap gives repeated opening and closing without wearing out as fast as a snap can, while a rigid snap retains contents more secure for shorter journeys or rougher sorting. Clear material also assists at the select-face because staff can see the contents without opening all pack, which saves time and reduces handling. The trade-off is that softer plastic can crease, label, or split if overfilled. A sensible spec retains paperwork tidy and movement through despatch smooth.

How to abbreviate Courier Bags?

Courier bags are a simple pack format, nevertheless the selection of material and closure determines whether parcels arrive tidy or damaged. A bag that is also thin can split on a sharp corner, while one that is above-specified adds cost, weight, and waste without improving the journey. Good polythene suppliers grade, the proper gauge, and a secure seal assist retain items protected through picking, stuffing, and conveyour handling. For lighter products, they save space in storage and make despatch quicker than a carton, particularly when secondary packing is unnecessary. The optimal bag is the one that matches the product and the route, because the gross grade soon shows up as returns and complaints.
