First, the basic concept of double-tape paper and carbon-free paper
Double adhesive paper is a special paper that uses a separable adhesive to coat both sides, and the double adhesive paper can be separated into two different colors of paper by tearing. This type of paper is usually used for printing or copying documents that require two or more copies. Usually, a paper with two colors can make three copies, a paper with three colors can make four copies, and so on.
Carbon-free paper, also known as carbon paper, is a special paper, its surface is coated with a special light-sensitive material, after coating to a certain thickness, a certain pressure is applied between the paper and the paper, under the pressure exerted by the upper layer of paper, the coating on the lower layer of paper is pressed on the lower layer of paper, thus forming the same graphics and text as the text or image on the upper layer of paper. This allows you to save two copies of the same content at the same time.
Second, the difference between double-adhesive paper and carbon-free paper
1. Different range of use
Double-tape paper is mainly used for printing or copying documents that require multiple copies, while carbon-free paper is usually used for writing and printing documents that require two or more copies.
2. The copying effect is different
Double adhesive paper can produce multiple copies, but the quality and clarity of each copy may be somewhat reduced. The effect of carbon-free paper copying is generally clearer, and there will be no reduction in the quality of the copy.
3. Different storage methods
Double-tape paper needs to be stored in a dry place to prevent the glue on the double-tape paper from falling off in a humid environment. And carbon-free paper storage is relatively simple, no special storage conditions.
4. Different service life
Due to the use of glue coated on the double-tape paper, the service life of the double-tape paper may be shorter than that of the carbon-free paper.
Although it looks similar, double-tape paper is actually very different from carbon-free paper. Carbon-free paper is mainly used for printing and copying documents that require two or more copies, and the copying effect is clear. Double-tape paper is often used for printing or reproducing documents that require multiple copies, but the quality and clarity of the copies may be reduced. Before use, the printing material should be selected according to the need.
