Advice & Usage Guide

Use;  We can manufacture plain and printed blockheaded mailing bags in blocks of 25 to 250.  The block is an extra piece of polythene which sits above the lip of the mailing bag and is melted to the one below it.  Block headed bags work in a similar way to wicketted bags but instead of a piece of wire wicket keeping the bags together, the bags are held together by a welded top header.  There are two holes on the block header so that the bags can be hung up for ease of use.  Below the welded header each individual mailing bag can then be torn off via a perforated line, much like the bags you find in supermarkets for bagging your fruit or veg. 

  • Perfect for fast moving packing and fulfilment lines
  • Ideal for speed and ease of packing

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.
