Firstly, there is an understanding of the definitions of the two. Release force, also known as release degree, refers to the degree of release of release film. There is no absolute value at this point, and it depends on the formula of each manufacturer. Depending on the amount of oil applied, it can be divided into light, medium, and heavy release forces. The peel strength refers to whether the release paper (film) is easy to peel off from the attached product, which is determined through strict testing.

Secondly, there is a slight difference in the objects used by the two. The release force is mainly aimed at objects such as protective films and films, while the peel strength is mainly relative to objects such as steel plates.

The unit is also an important reference for distinguishing between the two. The unit of release force is grams (g), while the unit of peel strength is Newton per meter (N/m).
