These black mailing / postal bags are manufactured from a strong mono LDPE 100% virgin polythene film and are 100% recyclable. The shade of black may vary from time to time but are 100% opaque so you cannot see the contents. They are extremely tough as used by leading mail order companies.
These postal bags are a mid-gloss on the outside. The film has been specially treated during the manufacturing process to ensure the glue-strip sticks permanently and also ensures that stamps/sticky labels and document wallets stick onto your parcels.
NOTE: it is very difficult to show exact colours on the photos - the shade may vary, if you need a particular shade please message us before purchase.
Tamperproof - permanent high tack self adhesive 'peel & seal' strip
Weatherproof and puncture resistant
Very strong but lightweight - therefore reducing postal costs
Extremely quick and easy to pack your parcels - at the same time giving them a professional finish especially when teamed with document wallets although you can use sticky labels
Use for packing almost anything - however more fragile items would be better bubble wrapped inside
If you have used black mailing bags before, you may have experienced problems with labels, stamps and even the glue tape on the lip not sticking very well. This is because black polythene bags have a tendency to be very glossy and this affects the adhesion. These black mailing bags have a matt-mid gloss finish to help combat that problem and also have the strongest permanent bag tape
