Closure considerations:

• Sealing
• Prevent permeation of the product. Example airless vs atmospheric pumps
• Consistent torque removal.
• Be convenient and easy to use
• Be aesthetically pleasing

We have written a similar article which explains the sealing capabilities for packaging in great detail. We have also talked about the different types of liners or seals. Click here to read this article.

Making a Packaging Closure

Plastic caps for jars or bottles are made one of two ways, injection molding or compression molding. Their advantages to both but material selection and aesthetics are the main considerations to be undertaken before choosing a method of production.

Not only the thickness of the liner, but the type of liner can have a lot to do with protecting your bulk. To ensure proper sealing, please reach out to our Engineering Team for consultations.
