White business envelopes

Cut your postal costs with our high-quality white envelopes

Stock up on the backbone of any stationery cupboard – white business envelopes. At RAJA, we stock most popular Royal Mail sizes including DL, C5, and C4. Professional and affordable, using plain white business envelopes is a great way to safely sending letters and invoices from your office post room to clients, customers, and suppliers.

When handling high volumes of postage, choosing a business envelope with a window can be a great way to reduce postage times. All you need is to print the contents with a pre-written address and ensure that it’s showing on through the transparent plastic window. If you’re sending personalised letters, stocking up on white envelopes with windows can be the most economical postal solution. However, if you’re looking to send confidential documents and would like extra security, our plain envelopes would the perfect addition to your office.

When you’re looking to buy bulk white business envelopes, a key factor can be how they’re sealed. We stock two different types for you to browse and choose depending on your preferences. Our peel and seal envelopes are designed with a pre-applied adhesive. All you need to do is to take off the covering, and then you can seal your envelope. Alternatively, the self-seal white envelope is ideal for when you’re sending multiple letters. Once the envelope is ready to send, simply push down the strip ensuring that it’s properly sealed.


All our white envelopes are sustainably sourced. That means that the paper used to make them is sourced from sustainable forests and are manufactured in factories that comply with environmental-friendly practices. When you buy white business envelopes from RAJA, you can rest assured that we are not taking more from the environment than needed.

Businesses receive many envelopes and mailers on a regular basis. At times, it can be difficult to understand what can be recycled, and what cannot. Our plain white envelopes are all recyclable. However, if you’re unsure about something in particular, our blog has plenty of information available on how to recycle envelopes.

With plenty of equipment to choose from, RAJA has almost everything you would need to fully fill your stationery cupboard.

If you’re handling larger volumes of post, then you’ll also need to think about how you want to display the addresses. For high quantities, investing in a label printer can reduce postage times drastically. Simply print and stick onto your envelopes once they’re ready to send.
