What kind of small paper bags do doctors fold when prescribing bulk medicine? Find out how to fold them.

General pharmacies will put the raw materials in a small paper bag, which is the kind that is sealed on three sides. You just need to turn the unsealed end of the small paper bag upward, first fold the upper right corner slightly below the upper left corner at a 45-degree angle, and then fold the sharp corner of the folded upper left corner to the right, which is a little larger than the previous angle, so that an extra piece will come out and be stuffed under the crease.
