Postal envelopes C5

Standard envelopes of size C5 162 x 229 mm

Made from paper with specific parameters, such as sufficient strength, flatness, constant shade, crush stiffness, etc. Standard paper weight is 80 g/m².

As a standard, we offer envelopes with straight flap and with 3 types of flap sealing (gummed, self-seal, strip-seal). Detail information is explained in Technical information.

Strip-seal – on closing flap is applied glue, which is covered by a strip of silicon paper. It can be simply peeled before envelope is sealed. The strip of silicon paper is removed, when the documents are already inside of envelope. That's why inserting documents into envelope are a lot simplier and cleaner. You or your documents don't touch the glue at all.
