Frequently Asked Questions

What is the difference between white and bright white envelopes?
Standard white envelopes have a natural white tone suitable for most everyday applications. Bright white envelopes have a higher optical whiteness achieved through optical brightening agents — the result is a crisper, more vibrant white that looks noticeably more premium alongside printed stationery. Bright white is the preferred choice for professional business correspondence, branded direct mail and premium invitation stationery.

What white envelopes are laser printer compatible?
80–120gsm white envelopes feed through most standard laser printers reliably. For guaranteed print compatibility, look for 'laser guaranteed' or 'printer-friendly' in the product specification. Window envelopes in particular benefit from a laser-guaranteed specification to ensure the window film does not melt at the fuser temperature.

What sizes do white envelopes come in?
The range covers over 160 sizes including standard formats: C7 (82 x 113mm), C6 (114 x 162mm), DL (110 x 220mm), C5 (162 x 229mm), C4 (229 x 324mm) and a range of square formats. Check individual product pages for the full size listing in white.
