Envelopes and Padded Bags

Shop a wide variety of Envelopes Online

Envelopes are an integral part of any office and they’re of great importance when it comes to packaging of flat objects like important letters or any official documents. Here at Office Stationery, we have a huge range of quality envelopes in all shapes and sizes, including big brown envelopes, small envelopes, C5 coloured envelopes and so many more. All of our envelopes are from top brands including Basildon Bond, 5 Star, Q-Connect.

The most common envelope sizes are C4 (A4), C5 (A5) and DL (A4 sheet or paper folded into 3 equal sections). There are also many types of sealing on our envelopes, these include peel and seal, gummed and self seal envelopes- gummed envelopes require moisture in order to seal them, and if you don\'t fancy licking hundreds of envelopes, you could purchase a handy flap moistener to do the job for you.

We also have a large range of specialty envelopes. Within this range you can find A5 and A4 Do Not Bend envelopes, plain money envelopes, cheap padded envelopes and large window envelopes. There are so many more options available here, but these are just a select few.

Does the world of envelope shopping seem daunting to you? Do you hate it when your colleagues shout really vague stationery requests as they pass you in the hall? Let\'s break it down a bit so you can become envelope savvy-

"Can you order some white DL Windows please?" Of course you can, all you need is a white DL Envelope (A4 folded into 3), with a window.

"I really need some Manilla C4\'s" All you are looking for is a A4 (C4) Envelope that is brown rather than white.

"Can you get me some C5 Windows White envelopes please?" I\'m sure you can work this one out now. You\'re looking for an A5 (C5) Envelope white and has a window.

Types of Envelopes

Windowed envelopes
A windowed envelope is an envelope with a plastic window in it. The plastic in these creates problems in paper recycling. Consumers who don\'t want to go through the trouble of ripping out the plastic window should put the envelope in a rubbish bag after use. 

Security envelopes
These have special tamper-resistant and tamper-evident features. They are used for high value products and documents as well as for evidence for legal proceedings.

Mailers
Mailers are available for full size documents. The Postal Service and Express mail carriers have large mailing envelopes for their express services. Others which are similar are available at office stationery at very reasonable prices.

These mailers usually have an opening on an end with a flap that can be attached by gummed adhesive, integral pressure-sensitive adhesive or adhesive tape. Mailers are usually constructed by:
• Paperboard
• Corrugated fiberboard
• Polyethylene, often a coextrusion
• Nonwoven fabric
