The bottle is cylindrical. It is mainly used for cosmetic products. The necks can be of 2 types: BPF 28mm and DIN 28mm. The main difference is that the DIN 28mm neck has a much smaller protruding ring around the neck.This gives the bottle a smoother look and allows flip-tops, triggers, pumps to be completed without losing the appearance of the strongly protruding ring as on the BPF 28mm. The optimal bottle weight is 32 grams. With this weight, the bottle is firm to the touch and less susceptible to mechanical damage. Vials are completed with 28mm BPF caps with a tear-off ring for tamper evident, flip-tops, triggers, aluminum caps.
