For glass containers, the finish is one of the most important elements. It has to remain free of all significant imperfections. This way, you can ensure a proper seal on your filling line.

Sadly there are defects that can result in a container leaking slowly. Crizzles on the top sealing surface would be a prime example. The real trouble here is that you may not discover this issue until you open the container. Therefore, you need to come up with ways of preventing this before it happens. To help, it's a good idea to learn about the main types of sealing systems found on containers.

Top sealing

We'll start by talking about the top sealing. If it's a crown cork type, the sealing surface shall be on top of your finish. This is common for narrow neck containers that you fill under pressure. There are also thread or lug systems. With them, you close the sealing surface on top of the finish using a screw type cap. They're popular for narrow neck bottles and wide mouth jars.

Side sealing 

This is the next system on our list. Here, the sealing surface exists on the finish's side. Additionally, you press the cap on to seal up the contents. You would typically use this system for the wide mouth jars you find in the food industry.
