Choosing the Right Envelope

Whether you are buying envelopes for domestic or business use, you need to ensure you have the right type for your requirements. Follow our guide today.

The Post Office Shop has a comprehensive range of Envelopes for you to choose from.  However, with such a varied choice of formats, sizes and materials available it can be overwhelming when deciding which envelope is the right one for you.

Envelope Size

Envelope sizes, just like paper are standardised.

DL – 110 x 220mm. One of the most common envelopes used. This envelope requires standard 1st or 2nd class postage stamps. It accepts sheets of A4 paper folded twice.

C5 – 162 x 229mm. This envelope accepts sheets of A4 paper folded once or an unfolded sheet of A5 paper. It is the largest size envelope that can be used with standard 1st or 2nd class postage stamps. However, this is dependent on the envelope and content weight.

C4 – 324 x 229mm. This envelope accepts sheets of unfolded A4 paper. It is an ideal choice for important business documents. It requires Large Letter 1st and 2nd class stamps. Again this is dependent on the envelope and content weight.

Envelope Weight

The weight of envelope is an important consideration, in particular for businesses where first impressions count.

80gsm. Ideal for sending invoices and receipts and other mail of between 1 – 3 sheets.

90gsm. Provides more opacity and strength and so can be used if you are sending 3 – 15 sheets.

100 – 110 gsm. When you want to make a good impression, this weight is perfect for sending letterhead correspondence to clients.

120 – 130gsm. A strong envelope, suited to sending brochures and other bulkier documents.

Envelope Colour

Using the right coloured envelopes can make all the difference. For business use, white envelopes are preferred as they give a more professional impression. Manilla brown envelopes tend to be used for domestic purposes, for sending bills and other general correspondence.

For marketing purposes, using brightly Coloured Envelopes make a really bold statement. No one wants their brochure or promotional material simply thrown in the bin. Research has found that using a stylish coloured envelope is 9 times more likely to be opened by a recipient than a white or manilla one.

Types of Envelope Seal

There are three types of envelope seal available.

Gummed – The most common type, also referred to as “lick and stick”. The layer of adhesive on the envelope flap is moistened and then sealed in place.

Peel and Seal – This seal has a longer shelf life than the traditional gummed seal envelopes, Release tape peels away from the flap to reveal a strip of gum which can then be pressed down to create an instant bond.

Self Seal – Quick to use but self seal envelopes have a shorter shelf life than peel and seal envelopes. There is a strip of gum on each flap of the envelope that when pressed together create the seal.

Type of Envelope

Plus Fabric Self Seal Pocket Envelopes

The type of envelope you need will be dependent on the contents. Are they fragile, confidential, bulky?

Window Envelopes – When sending large volumes of business mail, Window Envelopes save time and money. They negate the need for additional costly address labels.

Gusset Envelopes – Expandable Gusset Envelopes allow you to send catalogues, prospectuses and bulky reports. Stronger than standard envelopes, there is enough room inside to accommodate thick documents without damage.

Padded and Bubble Lined Envelopes – If you are sending delicate items in the post as a gift or to a customer, Padded or Bubble Lined Envelopes are ideal.  They are lightweight and so can keep your postage costs low. For that extra special touch why not try these PostPak Gold or Silver Bubble Envelopes?

Board Backed Envelopes – When you are sending important documents that need to remain flat during transit, Board Backed Envelopes are the right choice. They are most commonly used to send certificates and contractual documentation. Many will also include the text “Please Do Not Bend”.

Security Envelopes – Tamperproof, tear and burst resistant, specially designed Security Envelopes are suitable for sending confidential legal documents or medical reports. A cheaper and lightweight alternative to card packaging these envelopes provide you with a high level of security and confidentiality.

Polythene Envelopes – For a lightweight yet strong mailing solution, Polythene Envelopes are great for sending customer orders in a cost efficient way. They are also waterproof and can be combined with other lightweight packaging such as Bubble Wrap.
