Introduction

MCA is the designation for the agreement regarding a common finish specification between the

companies Metal Closures Limited in Great Britain and Alcoa in the USA which are at the origin of these

finishes. Originally, these finishes were used on “one way” (single trip) bottles with aluminium closures.

The advent of the returnable market in Europe made it necessary to redesign the neck finish to overcome

shortcomings in thread and sealing performance. The main differences between the finishes are

concerning the thread profile and its pitch.

Historically, the development of the MCAs is partially explained by the differences presented below:

— MCA1: “flat” under-thread profile, well adapted to the plastic closures;

— MCA2: round thread profile, more robust and hence better adapted to returnable bottles, but with

more risks of ‘blow-off’ with plastic closures;

— MCA3: thinner thread with flat profile both under and above the finish, closer to the MCA 1, and

better adapted for plastic closures and to high pressure than MCA2;
— MCA R (R for round profile): based on the MCA2 but with deeper thread;

— MCA (RF for round flat): compromise between MCA1 (flat profile under the thread) and the MCA2

(strong wider thread profile).
