Cumberland Envelope Strip Seal Heavy White Pocket B4 353 x 250mm Box 250

Strip seal is ACCO's name for a peel and press closure. A narrow release liner runs along the flap; you lift it off and press the flap down. No water, no sponge and no moistening machine are involved, which is why it suits a bench where envelopes are filled and sealed by hand.

This is a plain face envelope with no secretive lining. A secretive envelope carries an opaque printed pattern on the inside of the paper so the contents cannot be read when it is held up to the light. If what you are sending carries names, account numbers, salary figures or medical detail, order a secretive envelope rather than this one.

Cumberland make this size in more than one stock. This code is white in 100gsm. MPN 613329 is the same size and the same strip seal closure in the other stock, and is listed separately. They are not the same code, so order on the colour and the weight you actually want.

No printer rating is published by Cumberland against this code, so we do not claim one. ACCO publish a laser rating on a separate laser envelope range and it does not carry across to this one. If you need to overprint, ask us and we will point you at a code that is rated.

No forest certification code is published against this code. Cumberland is an ACCO Brands line and ACCO Australia has no anonymous route to a first party environmental statement, so we have nothing to cite and publish nothing. We can put the question to ACCO in writing.

No box weight is published for this code, so the variant weight is left unset rather than estimated. Nor is a carton quantity published. We can confirm both with the supplier before you place a large order.

Cumberland's own trading name for this code carries the word heavy. ACCO publish no definition of it, so the figure that matters is on the page: 100gsm. The word heavy runs through the trading name used across the dealer channel and carries no published definition of its own, so compare the gsm figure rather than the word.
