Now with Lower Minimum Orders & Reduced Prices!

Our ever-popular Baby Blue Mailing Bags (also known as Bright Blue Mailing Bags) are now even more accessible — with minimum order quantities starting at just 10 bags and significantly reduced prices, there’s never been a better time to stock up.

These mailing bags have long been a favourite thanks to their vibrant colour, glossy finish, and exceptionally lightweight design — helping to keep your postage costs low.

Crafted from our special 3-layer COEX blend (blue exterior, white middle, and black inner layer), they offer a stylish look with strong performance. The 45-micron film is considered light duty, yet still provides excellent puncture resistance and strength.

We also ensure:

  • Permanent self-seal adhesive

  • Glossy, printable surface ideal for stamps and labels

  • UK-manufactured quality

If you're shipping heavier or sharp-edged items, be sure to check out our Heavy Duty Mailing Bags for added durability.

Advice & Usage Guide

Use;  The bags will arrive folded or laid flat in an outer Carton.  Once you unpack the mailing bags, simply slide or drop your product into the mailing bag.  The best method for sealing the mailing bag is to then lay it on a flat surface, lip/glue facing up.  Peel off the release tape from the lip which covers the glue and then fold the lip over onto the body of the bag.  We strongly advise that you only fold the lip over to where it naturally wants to fold to and no further.  If you fold the lip right over and seal it, lets say half way down the bag, then there is a chance that the glue will not form a perfect bond and the bags could come open.  We specially treat the mailing bags in the direct area where the lip folds over to as this helps with the bond formed by the glue migrating into the film.

Storage;  We recommend that mailing bags with Permanent Tape are stored at a temperature of 15 - 20 degrees and 50% relative Humidity.  If the ambient temperature falls to less than zero - 5 degrees then you should ensure that you have a means of warming the mailing bags in use.  This because the very cold temperature hardens the glue and so it takes longer to form a bond with the film.

Extra Padding?;  If you feel that you could do with a bit more protection for your products in transit due to them being fragile or delicate, then why not try our bubble inserts with these mailing bags.  You don’t even need to buy the same qty to match as you can pick and use when you feel you need to using bubble lining when shipping your goods!  Alternatively we stock bubble wrap and boxes.
