File folder is one of the commonly used folders in office. It is also called Kuai Lao folder or cardboard folder. In fact, it is called differently in different regions. It is mainly used when storing a large number of punched paper files. It is mostly used in personnel administration, general affairs, financial departments, and filing. Therefore, the specifications of the various file folders must be clear, and I hope this article can help you.

Size:

Europe uses A, for example: A3 A4 two sizes, the international standard paper is A4 paper 210*297

Japan uses B, for example: B4, B5, B6, several sizes, mostly in notebooks

The United States uses F. For example, FC is actually very rare and only used by a few US companies. If you work in a US company, you should pay attention.

China uses K, for example: 8K 16K 24K is actually a whole piece of paper cut several times, but it is not used much now, because the international standard is all A4

The size is not much to say, the file folder generally can be bought is A3 A4 FC, thickness 2 inches (55MM) and 3 inches (75MM), most of the other sizes are not produced or customized by manufacturers. A pack of 2 inches 55MM paper is 500 sheets and can hold 300 sheets by visual inspection.

Material:

The material is basically cardboard on the market. I heard that there are plywood and plastic, but it is rare. The most common is cardboard. The appearance material is divided into non-encapsulated, single-encapsulated, and double-encapsulated. There are more glues in the market.

Non-coated: Also called non-coated, as the name implies, it is a file folder with no face and no skin. In fact, it is kraft cardboard or gray board.

Single encapsulation: It is called half encapsulation, which can be understood as wearing a suit without a vest. There are many exterior materials, such as PP, foam, PU, patent leather, non-woven fabric, lacquer tape, copy paper, plastic, gauze, and sulfuric acid paper. Of course, most of them are still encapsulated.

Double encapsulation: It is also called full encapsulation, even if you wear a suit and a waistcoat, it is covered with rubber inside and out. It is rarely sold, but the quality is good.

Types and accessories:

At present, most of the file folders are two-hole levers. The English literal translation is a lever arch file. There are also more alternatives such as Japanese double-opening tube folders and single-opening tube folders. Lever arch files are more common in price and easier to accept. Open tube folders are more expensive, mostly imported, so the price is also more expensive.

Use:

It is generally used by the department that stores the files. The A4 size is mostly used in the personnel, administration, finance, and business departments.
