Business envelopes can be as important as the message inside them. They’re the first thing that your customer will see in the post, it’s like the front cover to the letter inside it. Sometimes customers may not even open the envelope due to how it looks, so all the hard work to make the content inside the envelope may never even get seen. 

That's why at HuntOffice we offer lots of customisations, so that you can have the perfect envelope for your customer. We have customisations in style, size, quality, colour, the type of seal and more. 

We also offer one of the largest selections of business envelopes online. Our assortment of business envelopes includes large packs of 500 or 1000 business envelopes, which are ideal for large companies. We also do smaller packs of 50 or 100 suitable for home or small office use. We supply gummed business envelopes as well as self-seal and peel & seal envelopes. You can choose from wallet or pocket style business envelopes from top quality brands like 5 Star, Q connect and plenty more.

2. What quality do you require?

Choose from 70gsm (lightweight) to 130gsm (heavyweight) paper. Heavyweight paper is stronger and when coupled with a smooth finish it helps deliver the right first impression to the recipient.

We offer a wide choice of business envelopes in various weights, materials, and finishes. This allows you to choose the right product for your needs.

- Professional Range
These are high quality business envelopes that offer the very best in paper quality and finish and will help your company deliver the right impression.

- Environmental Range
For the more environmentally conscious, these products have environmental accreditation.

- General Office Range
A more basic offering in terms of quality of paper.


3. Do your business envelopes need a window?

Window business envelopes are useful for bulk mailing, invoices, and statements where the recipients address is automatically printed on the document. The size and position of the window is always described with the flap upwards.

4. Choose the colour of your business envelope.

Generally, this is a simple choice of white or manilla/brown. However, other colours are available in the prestige range. Being able to choose the colour of your business envelope allows you to have extra customisation, to make your envelopes that bit more personalised.

Types of Business Envelopes available:

• DL business envelopes are one of the most sized envelopes. These business envelopes hold an A4 sheet folded twice or an A5 sheet folded once. A4 envelopes are also known as C4 envelopes. A4 envelopes are a very popular envelope as they are large enough to post documents, files, leaflets, and other paper documents in A4 size. C5 business envelopes hold an A4 sheet folded once or an A5 sheet unfolded.

• Wage slips are extremely confidential so distributing wage slips in wage envelopes eliminates the danger of getting the wage slips mixed up with other envelopes. In this selection we have Sage compatible wage envelopes which have a small window only revealing the employees name as well as New Guardian wage envelopes which have a pre-printed layout for itemising payslip details.

• Protect valuable items during postage with padded mailing business envelopes. We supply a broad selection of protective envelopes which come in various sizes. Ideal for smaller items like mobile phones to large format bubble bags that can carry A4+ sized items. If you have more delicate or heavier items, we have a range of padded mailing business envelopes that are made of extra strong paper which is puncture and tear resistant.

• In our protective envelopes section, you will find a range of tamper evident zip closure cash bags which are all made of heavyweight durable material to ensure the secure and safe transportation of cash. In addition, we have a choice of extra strong large capacity business envelopes in a variety of sizes ideal for posting more awkward shaped items.

• Need to post large bulky documents? Then have a browse through our selection of gusset envelopes. A gusset envelope is an envelope with expandable sides ideal for posting items such as brochures or catalogues. In this section there is a choice of either plain or window in either brown or white.

• Keep important documents safe while posting with board envelopes. These durable envelopes are made with extra strong cardboard, and they also have a printed instruction that says ‘please do not bend’ to ensure that they are transported properly. We offer board envelopes in packs as small as 25 rights up to large bulk packs of 1000 which are available in a range of sizes to suit.

• As well as the standard size business envelopes we also supply a large range of non-standard size business envelopes for posting unusual sized items and documents. These are available in small packs up to large packs of 2000 ideal for high volume users.

Jiffy Airkraft Size 2 205x245mm White Bubble Lined Postal Bags Pack of 10
  Jiffy Bag Review   
  "i Just love these white Jiffy Aircraft bubble lined postal bags. They are great quality and I have great peace of mind sending my items off in them. The No 2 size suits me perfectly but I have purchased the other sizes and was not disappointed. They come in a pack of ten and are so cheap from hunt office. I would highly recommend."
