Black 21″ x 24″ – 525mm x 600mm Mailing Postage Postal Mail Bags

Description

If you want to be absolutely certain that your goods are not going to be seen in your mailer and budget is a requirement, then these Black mailing bags are just the thing.  All of the mailing bags that we manufacture are designed to be opaque and non see through however.  Our Black mailing bags are a very popular line due to the cheap costs. 

Our Black mailing bags have been part of our stock range of mailing bags for over 7 years now and are very popular with mail order companies.  These mailing bags are manufactured in a mono film containing recycled  film. Mono film is a polythene which is made up of one layer unlike the two or three layers you get with Coex.  The shade of black may vary slightly due to the recycled content in the film.  We have manufactured these bags at 55mu/220gauge and they are also 100% degradable.  

The film is completely opaque so that you cannot see contents. Recycled film can sometimes have a tendancy to smell slightly.  If you have used black mailing bags before, you will have experienced problems with labels, stamps even the glue tape on the lip not sticking very well. This is because black polythene bags have a tendancy to be very glossy and this effects the adhesion. We have combated this problem by making ours in a Matt-Mid Gloss finish and incorporated our strongest permanent bag tape.
