Mail Hardy Mailing Bags 13 x 19 ", 330 x 485 + 40mm Lip

If you are looking for a really strong mailing bag, then look no further than our Mail Hardy. Manufactured in 70micron thickness which is 280gauge, these bags are manufactured using a unique blend of raw materials which gives them excellent puncture resistance and tear resistance.  If you are posting goods which have sharp edges or pointed parts then these would work for you.  We do recommend that goods with very sharp edges are wrapped in material like bubble wrap first or you could use our bubble inserts, which gives a bit of extra protection. You will not be dissapointed with these bags and samples are free to try.  The other benefits of this film is that the outer surface is very low slip so literally anything will adhere to it.  The glue on the mailing bags lip, forms an instant bond, even in very low temperatures.

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.
