MAILHARDY MAILING BAGS
New to our already massive range are our Mail Hardy Mailing bags. Due to popular request last year we have introduced this new superior strength mailing bag. Manufactured in 70micron thickness which is 280gauge. The film contains special additives which make the film very strong indeed and very difficult to puncture or tear. The other benefits of this film is that the outer surface is very low slip so literally anything will adhere to it.
The Mail Hardy Mailing bags are 100% Recyclable and manufactured using our MDPE medium density blend of polythene.
The glue on the mailing bags lip, forms an instant bond, even in very low temperatures
As these bags are not manufactured with a black inner, the level of opacity is around 90%

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
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.
