The art and science of beverage technology
ISBT Threadspecs® are voluntary, beverage focused, finish guidelines. Information not included in the guidelines (caps, additional dimensioning, etc.) generally fall under the proprietary expertise of cap manufacturers and are therefore not included. ISBT's ability to answer questions about caps is extremely limited. We would suggest contact companies listed in the Caps & Closures section of the Beverage Industry Resource Guide as a starting point for finding a partner to work with.
