Poly Postal Packaging is a
leading manufacturer and
supplier of polythene and
Our best selling heavy duty mailing bag. Manufactured in a very thick 90 micron polythene. This is twice the thickness of your average mailing bag in the UK market and they are very popular. Manufactured from a high % of post consumer waste so a preferred environmentally friendly option should you want it.
The bags can have a tendancy to smell slightly. This is because they are manufactured from post consumer waste, similar to the smell you may associate with black bin bags. The shade of the outer grey can vary as the film is recycled.
With a unique grade of hot melt glue tape and brilliant tear and puncture resistance you can count on.
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.
