Explanation of Neck Finish
The Glass Packaging Institute (GPI) and the Society of Plastics Industry (SPI) created a set of guidelines to establish standards for threading on containers.
- 400: 1 thread turn
- 405: 1 thread turn but usually in glass
- 410: 1.5 thread turns
- 415: 2 narrow thread turns
- 425: two thread turns but is most commonly found on smaller-capacity containers such as vials.
- 430: 1 or 2 deeper than the uniform standard thread turns. This unique neck shape is known as a buttress and is designed to help the user pour product with better accuracy.
- 485: neck finish are commonly found on glass Paragon jar. It takes 400 closures but it’s ideally suited for spice caps.
