Choose by Size

We understand that with having so many sizes and colours of mailing bags in stock, it can be difficult to navigate through the site to find your best option. So to make things a bit easier, we have made a chart for you which lists all the sizes and the relevant colours stocked in those sizes. Just click on  MAILING BAGS CHARTThe page will pop open in a new web browser window.  Each product has a code for example PPP-1, if you type that code into the search box at the top of the web page it will automatically search and then list the product in a drop down list.  This chart will be updated regularly.   The refine Search boxes below are all listed in inches

A commonly asked question is " what size mailing bag do I need for my product ".  There is no set formula really to work out what size mailing bag you need so the best option is to ask us for a sample.  Having said that we have devised a calculation here which seems to do the trick, give or take and is one we use all the time.  We do not guarantee that this formula will give you the exact size mailing bag required, its is merely a guide!

Lets say your product is  -  Width 100mm (3.9") x Length 200mm (7.9") x Depth 50mm (1.9"). Width of the opening on mailing bag is W + D = 150mm + approx 10mm Clearance, so approx 160mm.   Depth of mailing bags is L + D = 250mm + 10mm Clearance, so approx 260mmOverall approx size of mailing bag required would be 160mm (6.3")  x  260mm (10.23")  +  the self seal lip which would be around 30-40mm

IMPORTANT NOTICE ABOUT GLUE TAPES ON MAILING BAGS  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

Why not have your bags printed with your web site address or company logo for an extra small fee!  We offer a screen print service for all our stock mailing bags.  This is only for a standard 1 colour ink print on 1 or 2 sides of the mailing bags.  Please click here for further details  " Printed Bags and Packaging "
