A plastic file clip, also known as a document clip or a paper clip, is a small and lightweight device made of plastic material. Plastic file clips come in different sizes, ranging from small clips that can hold a few pages to large clips that can hold up to 50 pages or more. The most common shape of a plastic file clip is rectangular or triangular. The arms of the clip may be straight or curved, and the hinge may be at the top or the side of the clip.The grip strength of a plastic file clip depends on the size and design of the clip. A larger clip with stronger teeth will be able to hold more pages securely.
