Our 50mu / micron Metallic Blue Mailing Bags have been part of our stock range of mailing bags for a very long time and are very popular indeed.  Not only are they a nice bright vibrant metallic blue, but they are also very lightweight and strong.  Postage costs will be reduced when using a lightweight mailing bag.  We manufacture the metallic blue mailing bags on site here in the UK, as we do all our mailing bags.  The blue mailing bags are manufactured from our special 3 layer COEX blended polythene film.  Metallic Blue on the outside, a middle unseen layer of white and then black on the inside of the bags. Most of our competitors make these particular bags in a 1 layer mono film which means you can see through the film!  The metallic blue mailing bags are glossy on the outside.  We specially treat the film in the manufacturing process so that the glue on the lip sticks permanently as it should and to ensure that the polythene film accepts stamps and your address labels etc.

As standard, our blue mailing bags are manufactured at 50mu / micron which is classed as light duty film and so is very light weight, yet still retains great puncture resistance and strength and also made from 3 layers of film.  The blue mailing bags are 100% Recyclable. 

We also manufacture these polythene metallic mailing bags in 2 other colours, Gold Metallic Mailing Bags and Metallic Silver Mailing Bags.

If you need bags for items with sharp edges and heavy in weight then ideally you should be looking at our Heavy Duty Metallic Blue Mailing Bags.  A more recent addition to our range, these bags are manufactured in thicker 75mu / micron film and possess excellent puncture resistance and strength and are also made from 3 layers of 100% recyclable film.

There are 10 popular sizes that we keep in stock for immediate despatch, manufactured at our plant in Lincoln.
