Polythene mailing envelopes, or mailing bags as they are often known, are a superior alternative to paper envelopes or traditional postal packaging. Lightweight, strong and waterproof, mailing envelopes provide ideal protection for your parcel's contents during transit, protecting them from rain and dirt, as well as the usual bumps and scrapes they undergo on their way through the postal system. Cheaper to post than traditional parcels due to their light weight, mailing bags are also simple to use, fastening with a single self-seal adhesive strip.

Mailing bags are…

  • Convenient for sending items in the post that require additional protection or are needed to carry a brand.
  • Great at keeping package contents safe and dry during traditional mail or courier post.
  • Also known as mailers, poly-mailers, plastic envelopes or mailorder bags
  • Made from polythene to provide a perfect waterproof coating for your mail - much better than soggy envelopes!
  • Very light which means that postage costs stay low
  • Strong which means your envelope won’t tear or rip before it reaches its destination
  • Similar in appearance to a regular envelope - rectangular and flat - and open in the same way, at one end to allow you to place your package contents inside
  • Simple to use, with an adhesive strip running alongside the opening of the bag. Just fill the bag with your postage contents, rip off the covering tape, fold down the flap and your mailing bag is ready to post. Easy peasy!
  • A great way to advertise your business. Get your company logo, design or slogan printed on the outside of the mailing bag and impress your customers as their mail lands on their doormat

Things people say about mailing envelopes

Pink Poly Mailers

Printed poly mailers in the 10 by 13 inch class sit in a deceptively technical corner of fulfilment: small enough for apparel, accessories and flat products, yet big enough for poor gauge control to display up as curling, split seams or wasted null space at the packing bench. A decorative outer face even something as apparently benign as a playful pink repeat pattern introduces proper production constraints, because ink stickiness, corona treatment and surface resistivity all have to be balanced against the slip properties needed for fast select-face handling and proper label application. The better bags tend to rely on co-extruded polythene suppliers with consistent melt-flow behaviour, allowing micron-specific gauging without making the film feel papery or brittle; that matters when a consignment is being compressed into sacks, cages or mixed pallets where puncture resistance and seam integrity are tested more severely than in a list of products photograph. There is also a logistics dividend in the low tare weight and improved volumetric efficiency of mailers compared with cartons, though the trade-off is a greater dependence on disciplined stock segregation and sensible secondary bagging where abrasion or moisture ingress is likely. From a circular-economy standpoint, mono-material polythene suppliers building is preferable to laminated or foil-backed novelty packs, provided the print system does not compromise recyclate quality and the film maintains enough tensile performance to avoid above-specification; utilising more resin than the duty in reality requirements merely shifts the burden from transport to feedstock. The result is not only a prettily printed envelope, nevertheless a small engineered component in the wider packing line one that has to satisfy branding, machinability, pallet stability and stop-of-life recovery without slowing the operative at the bench.

An empty fixture list for mailing bags says small about the state of the sectour; the proper movement is taking place at extrusion lines, fulfilment benches and returns desks, where downgauging has to be balanced against seam integrity, opacity and puncture resistance. Modern polythene suppliers mailers are no longer treated as throwaway sleeves nevertheless as engineered consignment media: co-extruded films with controlled slip, consistent melt-flow behaviour and micron-specific gauging must dash cleanly through automated bagging kit without curling, blocking or generating nuisance static at the select-face. The logistics case is equally pragmatic. A lighter mailing bag reduces tare weight and improves volumetric efficiency against rigid board formats, yet poor dimensional discipline can damage pallet stability, distort sortation scans and increase secondary bagging after a failed closure. Recycled-content films add another layer of judgement; feedstock variability can affect tensile performance and seal windows, while mono-material building improves recoverability where assortment streams are disciplined enough to assist it. The better specifications so sit in the unglamorous middle ground proper adhesive release, adequate surface resistivity, decent tear propagation control and print registration that survives handling because the warehouse floor has small patience for nominal sustainability claims if the stock cannot be packed, sealed, scanned and returned without friction.

Printed mailing bags specified with twin adhesive closures are less a cosmetic tweak than a practical response to reverse-logistics attrition on the warehouse floor. The first seal carries the outbound consignment with sufficient peel strength to tolerate sortation, cage loading and pallet overhang without premature lift; the second, held in reserve for returns, removes the need for secondary bagging and maintains select-face efficiency because the same format can serve dispatch and re-entry. In material terms, the performance hinges on the interplay between film gauge, puncture resistance and seal integritytypically a co-extruded polythene suppliers structure engineered for stable melt-flow consistency, clean print reception and controlled surface slip, so the bag runs predictably through packing benches rather than clinging, fishtailing or trapping air. That has a logistical dividend as well: low tare weight retains volumetric efficiency in check across high package counts, while a properly proportioned flap and closure geometry assist maintain pack stability once the item re-enters the returns stream. The circular-economy question is no longer peripheral, either; where the building remains mono-material, recyclability is materially simpler than with mixed-substrate formats, and the amortised energy tied up in a bag that performs twiceoutbound and backcompares favourably with separate return packaging introduced later in the chain.

  2. Once you have chosen your type of mailing bag, consider what size mailing bag you need
  3. Look at the contents that you want to post and calculate (or estimate) their size: height, width and breadth
  4. Choose the size of mailing bag that is slightly bigger than the contents of your post
  5. Write the address on the outside of your chosen mailer (this is easier when the bag is flat than full!)
  6. Place your mailing bag on the table and the contents of your post alongside it
  7. Ensure the contents are aligned in the same direction as the mailer
  8. Open the mailing bag, taking care not to peel the label off the adhesive strip (yet!)

Poly Mailers 10×13

The wholesale specification for poly mailers in the 10x13 format with a transparent-view face is less a matter of nominal size than of control across gauge, seal geometry and film clarity; a 10x13 bag that drifts by a few microns in thickness can alter both tare weight and puncture behaviour once consignment volumes reach the pallet-load scale. Clear polythene suppliers brings its possess compromises: the film must retain sufficient tensile strength and tear resistance while allowing contents, labels or secondary bagging labels to remain visible at the select-face, and that tends to place pressure on melt-flow consistency, slip additive balance and the quality of the side-weld. In a warehouse setting, the attraction is plain enough flat mailers cube out efficiently, impose small dead weight on carrier networks, and reduce the null occupy associated with cartons nevertheless pallet stability and operatour handling still rely on packs being counted, banded and packed without excessive film memory or blocking. The more credible wholesale stock now leans towards mono-material polythene suppliers structures where potential, since mixed laminates complicate recovery; even then, recycled-content claims have to be squared with seal integrity, optical stop and the abrasions caused by automated sortation. Done properly, the transparent 10x13 mailer is a small component with a surprisingly long engineering tail: packaging line rhythm, volumetric efficiency, stock rotation and stop-of-life handling all sit inside that apparently simple sleeve.

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

Mailing bags sit at the less glamorous stop of distribution engineering, yet their specification has a disproportionate effect on mailing performance; a grey co-extruded polythene suppliers mailer with a proper self-seal strip is not merely a sleeve, nevertheless a calibrated containment system for low-mass, high-volume consignments. Gauge selection is where the trade-off starts: also light and puncture resistance suffers at the sortation cage, also heavy and tare weight erodes postage efficiency across thousands of units. The better grades grasp a consistent film profile, with polymer chains oriented to give tear propagation control while preserving flexibility at the pack bench; seal integrity relies on adhesive laydown, corona treatment and surface energy rather than brute thickness alone. On the warehouse floor, size rationalisation matters only as much as material science. A sensible spread of mailing bag formats improves select-face efficiency, reduces secondary bagging and limits null occupy, which in turn assists pallet stability and volumetric efficiency through the outbound stream. The circular argument is more exacting than the normal rhetoric recommends: mono-material polythene suppliers building facilitates recovery, nevertheless only where inks, labels and closures do not compromise reprocessing, and where melt-flow consistency is maintained in the recycled feedstock. Done properly, the humble mailing bag becomes a small exercise in amortised energy, damage mitigation and process discipline.

Printed mailing bags sit in a useful middle ground between plain secondary bagging and rigid carton board: they reduce cubic volume at despatch, trim tare weight across a consignment, and assist maintain pallet stability simply because there is less dead space being moved through the network. The technical merit, nevertheless, is not merely that they are lighter. A well-specified mailer relies on disciplined control of micron-specific gauging, seal integrity and melt-flow consistency amid extrusion, otherwise the film drifts from supple to brittle and beginnings failing at the corners below sortation stress. Where branding is carried on the outer web, print stickiness and surface treatment become part of the engineering brief as much as the artwork does; poor corona treatment or an ill-matched ink system can compromise surface resistivity, attract warehouse dust, and create handling issues at the select-face. In practice, the better format is normally a mono-material polythene suppliers building with enough opacity for discretion, enough puncture resistance for return logistics, and a closure system that mitigates tampering without overcomplicating opening. That combination facilitates faster packing bench throughput while preserving a cleaner recycling streaman unglamorous nevertheless material earn when feedstock recovery, amortised energy and volumetric efficiency are being weighed together rather than treated as separate conversations.

Paper Courier Bags

Mailorder bags sit in an awkward nevertheless highly practical corner of fulfilment engineering: they are expected to absorb the bruising of package networks, present cleanly at the select-face and do so without adding dead weight to the consignment. That pushes converters towards carefully specified polythene suppliers structurestypically co-extruded films with controlled melt-flow consistency and micron-specific gaugingbecause the contrast between a bag that seals reliably and one that necks, splits or cool-cracks in transit is often buried in chain orientation and seal-window tolerance rather than headline thickness. On the warehouse floor, the attraction is less romance than arithmetic; reduced tare weight improves volumetric efficiency, secondary bagging can often be eliminated, and pallet stability tends to improve when stock is packed in formats that do not trap air or create uneven load faces. The less glamorous complications are static build-up, overfilled seams and returns handling, each of which creates friction at scale, so anti-static additives, permanent adhesive strips and mono-material buildings are increasingly specified not as a gesture to fashion nevertheless because they facilitate fast packing, cleaner recovery streams and more credible recyclability once the bag has completed its rather short, mechanically demanding life.
