Kraft paper mailing envelopes are envelopes with particularly high strength. Thanks to their properties, they are excellent for sending heavy correspondence. Kraft envelopes provide a high level of protection for documents in transit, so they reach the recipient completely safe.
Although the name of this type of paper comes from the German word for "strength", it was developed in the mid-19th century in the USA. Thanks to its unique characteristics, kraft paper has become popular all over the world. The production process involves cooking long-fibre pulp, which gives the paper its high strength and wear resistance. Kraft paper can vary in grammage and colour: both bleached and brown paper are produced.
Mailing envelopes are made from kraft paper with a grammage of less than 60 g/m². The same paper is used to make decorative cards and bags, and it is also used for packaging and as a protective wrap. Heavier paper is used to produce corrugated board and sacks.
Kraft paper mailing envelopes are often a successful and interesting solution for a range of tasks. Besides their main purpose of sending letters, such an envelope is an aesthetically pleasing decorative object. A brown or white kraft envelope looks attractive and original thanks to its fibrous texture. A greeting card given in such an envelope will delight the recipient twice over.
Kraft paper mailing envelopes can be bought both at post offices across the country and from companies specialising in their production. In the latter case, you can order a batch made in the sizes you need.
