These brown mailing bags have been part of our stock line for around 5 years now and have been a great addition. We manufacture brown mailing bags in our special 3-layer COEX blend. Brown on the outside, a middle unseen layer of white and then black on the inside of the bags. The brown mailing bags are a bit 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 address labels etc.
The brown mailing bags are manufactured at 50mu / micron which is classed as medium duty film and so is quite light weight also, yet still retains great puncture resistance and strength. 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
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.
