Tear-off horizontal perforations at page top/bottom are exactly in-between standard perforations, at whatever regular interval is used for that particular paper. When the perforated edges of the paper are manufactured so that they tear off the pages in strips, those strips are known as "perfory."
Tearing strength is the ability of the paper to withstand any tearing force without break. It is useful to evaluate web runability, controlling the quality of newsprint and characterizing the toughness of packaging paper. Tear strength for paper is measured in units of force, frequently measured with the Elmendorf Tester.
A loose leaf (also loose leaf paper, filler paper or refill paper) is a piece of paper of any kind that is not bound in place, or available on a continuous roll, and may be punched and organized as ring-bound (in a ring binder) or disc-bound.
