What are Business Envelopes?

Safe and secure, whether sending contracts, documents, payslips or any kind of correspondence, you need an envelope you can trust. Customers of any business always appreciate a company that takes their privacy seriously, and an industry-standard business envelope can give you that professional edge. A good business envelope will be thick enough to keep sensitive information safe and has a gummed or strong self-seal option so it can’t be opened and resealed or tampered with along the way to its destination.

Why Choose Business Envelopes?

Business envelopes help build trust. All customers want to know that the company they are working with is legit, and by respecting their privacy and presenting yourself in a professional manner, you can deepen those layers of trust. By opting to send correspondence through the industry approved standard, you put your best foot forward as a brand.

Another great aspect of business envelopes is the fact that they can be easily personalised to align with your brand image. A standard business envelope is white with a blue opaque interior, making the external surface easy to stamp with your own personal logo – or you can choose to keep it plain and simple.
