Airtightness is an important indicator of glass bottles, especially for bottles containing food. If the air leaks, it will cause food spoilage, which is harmful to human health! So how to test the air tightness of glass bottles?
1. Observe whether there are inclined caps, warped caps, sliding tooth caps and crushed cap claws in the matching caps of the glass bottles.
2. Observe whether the cover surface is concave and whether the safety button is sagging to determine whether there is a vacuum in the glass bottle.
3. Measure the tightening position When measuring, first find the straight seam of the bottle neck on the mouth of the glass bottle, and use a ruler to measure the distance between the straight seam of the bottle neck and the starting edge of the nearest cap claw, which is the tightening position. The measured value taken from the right side of the straight seam of the bottle neck is positive, and the value taken from the left side of the bottle neck is negative. The above is the article on how to check the tightness of the mouth of the glass bottle brought to you by the editor. I hope it will be helpful to you.
