Abstract
An easily tearable film and a method for preparing the same are described. The easily tearable film includes a unidirectionally tearable film with several cutting lines thereon. Each cutting line has a first end point and a second end point, and has a joining point with an imaginary straight line parallel to the tearing direction that passes the first end point of the next cutting line. The easily tearable film can be easily torn in a direction different from the tearing direction of the unidirectionally tearable film because of the cutting lines.
