Finding a package for your product is only the first part of the job, now you need to make sure your product will pass seal & weight loss and how the bulk is to be dispensed. This where you much choose your packaging closure.
Here are some things to consider when choosing a closure for your package.
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.
Using a Packaging Closure
The success of a standard threaded closure is based on using the proper neck or thread finish along with the proper application torque. Liner choice is also a consideration. 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.
Common Materials used for packaging closures
There is a wide variety of resins and materials that can be used for a closure. Understanding the bulk as well as the aesthetic look desired can determine or limit the choices for a closure.
Common types of packaging closures
Here are some common types of closures:
Continuous Thread Closures: These closures are used with a container having a constant spiral protruding on the outside of the neck. They are used across various industries, including food, health & beauty, and household items.
Child Resistant Closures: These closures are commonly used for items to be kept in child-resistant packaging.
Tamper Evident Closures: These closures are used to give affirmation that the original product is flawless.
Dispensing Closures: These closures are used to manage the product amount getting dispensed when utilized.
Bar Top / T-Top Closures: These closures are generally used for particular kinds of foods spirits. The top part can be made of plastic, metal, wood, or glass. However, the bottom part is usually a cork.
