Mailers & Mailing bags - A Guide

Although Jiffy bags can be considered mailers, what we refer to as mailers or mailing bags are essentially polythene envelopes. These quality postage bags all have flaps and sealing strips with a non removable adhesive.

Our ranges in this area are:

Clear mailing envelopes (mostly made to paper sizes)
Grey opaque mailing bags
Metallic Blue Mailing bags
Baby Blue Mailing bags
Bright Pink mailing bags, and..
Dark Green (Knightsbridge) mailing bags.

Can I get mailers printed?: Yes. As always there are minimum quantities for custom postage bags (about 5,000 for opaque bags)
but printing on one or both sides is not a problem.
Can I get special sizes made?: Again, yes. Also subject to minimum runs of 5-10,000 depending on the bag size. The smaller the bag, the higher the minimum quantity is likely to be.
Could I use these for small wooden kits?: Not without some form of wrapping to protect the bag from the edges of the wooden parts. A Jiffy bag would probably be more appropriate.
What weight will the opaque bags take?: They will take quite a lot of weight, but if you then consider handling, throwing, dropping etc. I wouldn’t put more than 3 or 4 kilos into one. They are really designed for clothing, papers and other similar items.
How thick are the grey & blue mailing bags?: They are mostly 60 microns, the same as those you might get from well-known mail order companies. There are also a couple of heavy duty ones available.
Can I stick a label or document envelope on the mailers?: Yes. Most types of adhesive will stick to them well.

At Transpack we stock polythene mailing bags in clear, grey, pink, metallic blue, bright blue and dark green for all your mail order products. All these mailing bags are medium duty, 60 micron to avoid the product showing through the bag, with a strong and permanent self-seal strip for security.

I put this mouse inside one of our bubble bags for added protection. If you’d like to see more information on those, see the video on the bubble bags page of the website. The bags seal by tearing off the strip and firmly pressing into place. The bonds take 10 to 15 seconds to hold. They are suitable for most mail order products such as gifts, boxed items, toys, sports goods, garments and hardware, providing they are not too heavy – in which case we'd recommend using our Ultra Heavy Duty Grey Mailing Bags, these are 90 micron and they are very strong. They are ideal for sending out heavier products. They also have a very secure permanent super tack self adhesive tamper proof strip.

As I said earlier, the bonds take 10 to 15 seconds to hold. Have a look at this one I did earlier, it's really strong. Our Clear Mailers are 35 micron and are available in C3, C4 and C5. The range includes a C4 Mailer with a Write-On Panel for easy addressing and a 70 micron heavy duty version too, for bulkier, larger deliveries.

When packing mailing bags, always protect fragile and brittle objects – for that, we'd recommend bubble bags, tissue paper or bubble wrap.

Order online or by telephone before 3pm and we aim to despatch your order the same working day. Orders over the value of £35 are delivered free of charge. For any other questions call our customers service helpline on 02380869999 or visit our website and our friendly staff will be more than happy to help you.
