Heavy Duty Metallic Blue Mailing Bags 13 x 19, 330 x 485 + Lip, Qty 500

I contain a minimum of 30% recycled plastic!

Containing a minimum of 30% Post Consumer Waste Plastic, Not only are they a nice bright vibrant metallic blue, but they are also very strong.  We manufacture the metallic blue mailing bags on site here in the UK, as we do all our mailing bags.  The blue mailing bags are manufactured from our special 3 layer COEX blended polythene film.  Metallic Blue on the outside, a middle unseen layer of white and then black on the inside of the bags. Most of our competitors make these particular bags in a 1 layer mono film which means you can see through the film!  The metallic blue mailing bags are 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 and your address labels etc.

The blue mailing bags are manufactured at 75mu / micron which is classed as heavy duty film and possess excellent puncture resistance and strength as it is made from 3 layers of film.  The blue mailing bags are 100% Recyclable.  If you need bags for items with sharp edges and heavy in weight then these are the bags to choose.

We also manufacture these polythene metallic mailing bags in 2 other colours, Gold Metallic Mailing Bags and Metallic Silver Mailing Bags.

There are 6 popular sizes that we keep in stock for immediate despatch, manufactured at our plant in Lincoln.

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.
