Probably one of the most popular envelopes used today is the 5 x 7 envelopes, and most of us know that and use them often.There are a lot of different types of envelopes though, which are used for various purposes that you might be curious about.
Envelope Weights
Envelopes are constructed in various different ways, including different thicknesses, and weights. A system known as GSM, or Grams per square inch is used for the measurement scale. The method used to grade paper is the same as this method. The higher the GSM number, the thicker the paper or envelope will be.
