When searching for the right packaging components, it always helps to have a solid understanding of your options. This is especially true with closure liners, unlined caps, and linerless caps, where their performance is key to preventing leakage and loss of product quality. It can be a challenge to navigate their differences and design details, but our packaging specialists have put together an introduction to what you need to know about closure liners.
A Few Basics About Closure Liners
The first thing to know is that there are many different types of closure liners, along with various types of caps that utilize them. They serve three main purposes, including preserving a vacuum seal, demonstrating product integrity through the use of a tamper-evident seal, and preventing leakage.
Not all products necessitate the use of closure liners; however, we strongly recommend talking through your product’s need for a vacuum seal, tamper evidence, or leak prevention. Some products, like cooking oils, are particularly vulnerable to leakage and other storage challenges and they depend on having a secure and sealed cap fit. Others may need a method of the dispensation that is not complemented by the use of closure liners, so these may be better suited to another option.
Linerless Caps
If your customers have a demand for a dispensing cap, like a flip-top cap or disc cap, you still need a quality sealing system but closure liners would block the product from dispensing. In these cases, a linerless system can give you both a quality sealing system and a fit for dispensing your product from the bottle or jar.
It is worth noting that many beverages and condiments utilize linerless caps. If this sounds like the right application for your product, we can help you explore a number of options including plug seals, crab claws, and land seals.
Unlined Caps
Not to be confused with linerless caps, unlined caps are simply regular continuous thread caps with no liner in them. With these caps, the seal is different and not often suitable for liquids. However, an unlined cap may be just what is needed for many products, like powders or tablets.
