What is GSM and why is it important when buying envelopes?11th Aug 2015
What does GSM mean and what does it mean for your envelope buying? We have the complete GSM guide for you today!
GSM is an acronym meaning ‘Grams per Square Metre’ So this translates into how much a single sheet of paper measuring 1m x 1m weighs. Effectively the higher the GSM number, the heavier the paper.
What difference does GSM make for your envelope?
GSM affects the quality and durability of your envelope. If your envelopes were of a thickness of say 35-55gsm which is what most newspapers will commonly be printed on, you would find most of your post would never reach its destination! 33-55gsm is far to thin for use in the envelope trade and like newspapers would tear very easily. However if you used a thickness of 400 gsm this would be the typical thickness of card and would be far thicker than would be needed for everyday postal needs.
Now there are certain GSM ratings which will keep popping up when looking round large number of envelope suppliers, such as www.expressenvelopes.co.uk. Most envelopes will fall into these categories.
