Let’s talk about threads

...But what exactly are threads?

Simply put, threads are the protruding lines around the neck of the bottle. They ensure that the matching closure will have a tight fit to protect your natural products from being tampered with or from leakage. The thread size depends on the size of the bottle neck as well as our closures. Our bottles and jars and corresponding closures must have matching threads. If in doubt, it’s always advisable to contact our sales department.


GPI and GCMI are the US norm for neck finishes and are followed by two numbers written like this: 22/400*. The first number indicates the neck finish diameter and is measured across the outside of the bottle’s threads. The second number refers to the height and thread style. Meaning the number of thread turns around the neck. Simply match the GPI or GCMI code listed in the product description to purchase the correct corresponding items.
* Please note that if a bottle has an additional ring on the neck, this may affect the choice of matching closure. For more details, please get in touch with your MIRON representative.

Special thread

A special thread differs from the standard threads because some MIRON products are tailored to unique (market) demands, differing from standard packaging shapes/sizes. This means that the choice of corresponding accessories is more limited. Make sure you match the diameter indicated in the product description with the corresponding Modern or Classic lids to purchase the correct related items.

At MIRON Violetglass we ensure that our closures always fit the corresponding bottles and jars. However, sometimes it can be a bit of a challenge to find the right glass packaging to fit the needs of your natural ingredients. We are always happy to answer any questions you may have, and to become part of your product journey.
