I'm working at a water bottling company in Maldives. Recently, we have changed our bottle cap from 27 mm. Alaska cap to 28 mm. PCO caps.
But came to know that there are two types of 28 mm. PCO caps called 28 mm. PCO 1810 and 28 mm. PCO 1881 depending on the neck finish of the bottle. Can anyone help me to get the drawings of the two different types of caps ?
