Loose-leaf binding is the simplest form of binding. Each page can be viewed comfortably. Unlike coil binding, loose-leaf binding is generally 3 or 4 holes.
The materials of the binder are available in stainless steel and plastic. The number of pages can be added or reduced after binding. It should be noted that, since most of the stainless steel binders are relatively thick, the front cover and back cover require thick materials to make the binder support firmly.
Loose-leaf binding is a good choice for specialized technical training manuals and product catalogs with different contents for different customers.
Another type of loose leaf is formed by a single or multiple screws and nuts. Many single editions, such as the special paper sample paper bound book and special material sample catalogues seen on the market, adopt this form. However, only a single page can be read in a fan shape on one side, and the screws are likely to fall off due to loosening. Multiple versions, such as a book of materials, conference materials, or bidding materials.
Double coils are also called YO coils and O-coils. Double coils are two-strand steel coils with preset sizes and specifications. Common materials are divided into two types: plastic-sprayed steel coils and plastic coils. Usually a round hole or a square hole is punched on the left or above the printed matter. After the double loop is passed through, it is pressed and fixed by a YO loop binding machine, and the entire binding process is completed.
After the coil is locked, no more pages can be added unless the coil is removed. The cost of double-coil binding is higher than that of single-coil binding. Of course, the bindingeffect is better and more durable.
Using double-coiled picture albums, any page can be completely flattened when reading, which is very easy to read and inquire. Books with a thickness of less than 30mm, such as tool books, technical manuals, recipes, VIS manuals, and architectural atlases, are most suitable for this binding method.
