Sealing & Closure Types
There are different sealing types used for various types of different applications. Viking carries the most common sealing types, occasionally known as art of locks. There are three main closures.
Self-Seal Envelopes
An easy way to close your envelope is with a self-seal closure. With this method both flaps have a strip of latex that bonds together after pressing them firmly. The latex is derived from rubber and ammonium making this a natural seal. Furthermore, the latex on these self-seal envelopes have a guaranteed shelf life of at least 6 months from the date of manufacture.

Peel & Seal Envelopes
The strongest seal to secure your envelope shut is with a peel and seal closure. With this method, the top flap is covered by a release tape that can be peeled away and then pressed down to form an instant bond. The glue hat is used on this envelope has a shelf life of up to 5 years.

Gummed Envelopes
Gummed envelopes need to be moistened in order to be closed. Gummed envelopes are the only seal type which are suitable for machine inserting where the sealing is performed automatically. The gum used on the flap is water soluble and made from a mixture of dextrin and synthetic resin, making them biodegradable. If these envelopes are stored in moderate conditions where the temperature is not too hot or not too cold, these envelopes should last for a number of years.
View productsEnvelope Styles
Envelopes are offered in either a wallet or pocket style. A wallet style conveys the opening is on the long edge of the envelope, whereas pocket envelopes have their openings on the short side.

Windows
In our range, you will find both envelopes with windows and plain envelopes (without a window). Windows in envelopes are mainly used to display the name and address of the recipient on the form that is inside the envelope. If you are planning to buy an envelope with a window, be careful about its placement. Keep in mind where you want the postage stamp to go, and then choose one where the window is positioned to your liking.
Weight
At Viking, we carry a wide range of envelope weights which refers to the paper thickness. The most common standard weight is 80 or 90 gsm. This is a typical weight for all of your standard mailings. The paper weight of an envelope is measured in gram per square metres (g/m ² or gsm) and can be seen as a measurement of paper density, and thus an indicator of quality. This means, the lower the gsm, the thinner and lighter the envelope. If you want to post single-sheeted papers with low costs and a high volume, you could decide to go for a paper weight lower than 80 gsm. These are often brown or manila envelopes and are a more environmentally-friendly option due to the reduced amount of paper use per envelope. If you are planning to buy a more deluxe envelope, then our standard envelope range of 100/110/120 gsm is more suitable for your needs. For very important documents which need more protection, anything above 130 gsm would be ideal; these are classified as either board backed or gusset envelopes.
Colour
Using the right colour for your mailings can make all the difference. Our range consists of envelopes in various colours and tints so you can determine what connotations are attached to your mail. White is the most popular colour in envelopes. It is offered in many different shades and formats to specifically meet your personal needs. This is ideal for sending business letters as it is the most neutral, simple, yet professional option to give your receiver the appropriate message. Brown manila envelopes are also quite popular in our range. It is a darker colour and commonly used for either low cost mailings or filing and document keeping because of its less-transparent quality. Coloured envelopes are used for less frequent usage, such as marketing purposes, birthdays, and invitations. Red, pink, green, orange, and blue are just a few of the many shades available.
