Poly Postal Packaging is a leading
UK manufacturer of polythene
and polypropylene packaging.
All our stock black mailing bags are now 100% recyclable and not degradable. The film is now manufactured in 100% Virgin polythene with no recycled content. This gives now for a much better quality bag!
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 companys. These mailing bags are manufactured in a mono film. Mono film is a polythene which is made up of one layer unlike the two or three layers you get with Coex. The black mailing bags are manufactured in 100% Virgin polythene and are 100% recyclable. We have manufactured these bags at 55mu/220gauge.
The film is completely opaque so that you cannot see contents. 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.
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 address labels etc. If you need bags for items with sharp edges and heavy in weight then ideally you should be looking at our Heavy Duty Mailing Bags.
MANUFACTURING TRADE TOLERANCES ON MAILING BAGS
Specification: All sizes and thicknesses are approximate. Standard tolerances are in line with industry standards. However, note in particular that bag width may vary by +/-3mm or +/-3% and bag depth by +/-3mm or +/-3% which ever is the greater. Where size is critical, a sample of the product to be packed must be submitted to us in order to agree size tolerances before the acceptance of your order.
