How many centimeters is the bandwidth of Maotai glue?

Because the electric tape is too thick to seal, there is a special film for sealing old wine with a width of 5 cm, which is very practical. After backing it with waterproof raw material tape, use wine sealing film to apply proper force and wind it several times. However, when using special sealing film, it should be noted that the wine top cover with plastic cover should also be tightly sealed, because if the film is cracked or the top cover is semi-film, the loose seal may volatilize from the top cover.
