'Disposable masks' of mask packaging machine information

Let's first understand the mask, whether it is a disposable mask or other masks, there are both fronts and backs. For a disposable mask, the darker color is the front, and the front is facing out. Look at the picture below, the position circled in red contains the metal strip of the nose clip. 2 The reverse side of the disposable mask is lighter in color, and the reverse side faces inward, which means that the lighter side is close to our face. In addition, it should also be noted that the end with the metal strip is above the mask, do not wear it upside down. 3 After clearly distinguishing the front, back, top and bottom of the mask, it is not far from the correct way to wear the mask. Wash your hands, make sure the light-colored side of the mask is facing inward (reverse), the end with the metal strip is facing up (upper), and hang the ropes at both ends on your ears. Seeing this, do you think you should wear the mask? Is it done? 4 The answer is definitely no. Look at the most important step. You need to press the metal strips on both sides of the bridge of the nose with both hands, so that the upper end of the mask is close to the bridge of the nose. Then stretch the mask downward so that the mask does not wrinkle and better covers the nose and mouth. 5Okay, you're done. After wearing the mask correctly, you will no longer be afraid of smog.
