In today's society, many food packaging bags displayed on the counter are
mostly serrated, with the purpose of making it easier for consumers to tear open
the bags and open them more conveniently. However, have you ever thought about

This issue involves the use of mechanics. When an object is subjected to
force, the force will change according to the shape of the object itself,
usually causing sudden changes in folds or sharp corners. Therefore, the

shape, retaining this serrated effect, allowing consumers to easily and
conveniently open the packaging bag.
The above is the reason why food packaging bags need to be made with serrated
mouth, and the benefits.
