Basildon-bond C5 Envelopes / A5 Envelopes

C5 Envelope Sizes

The international envelope size range has been developed to accommodate A size sheets - the range of envelope sizes is designated the C series. The C series of sizes are based on a basic sheet size of 917 x 1297mm and is used for envelopes. C5 envelopes are often inccorectly reffed to as A5 envelopes because of their ability to take A5 and folded A4 paper.

These C series envelope sizes are formulated to take A series paper exactly. For example, C4 for A4, C5 for A5 and C6 for A6. One of the most popular envelope sizes, DL, is however an exception to this. The DL designation is derived from the German DIN Lang, DIN being the German equivalent of the ISO standard, and Lang meaning long.  

Envelopes Usage

You will find a couple of variants offered such as C5 self seal envelopes and C5 window envelopes that removes the requirement to spend more time and expenditure labeling the outside of the envelope with the addressee's details.

Each of our C5 window envelopes has a space cut in the front side that allows the paper within to be observed. They will be commonly organized to ensure that the sending address printed on the page is apparent, saving the sender from having to duplicate the address on the envelope itself. The window is sealed with a transparent or translucent film to protect the letter inside. Our security envelopes come with a patterned style printed on the interior, which makes it complicated to read the contents.

Just because you save a significant amount on our cheap C5 envelopes this does not mean you are compromising on excellence as we exclusively sell quality envelopes  and a range of envelope sizes that have been thoroughly tested in our very own office.
