How Vented Liners Work
Now that we know what vented liners are, let's detail how each component works. While there are thousands of possible combinations for vented liner options, all vented liners will have three main parts: the membrane, the backer, and the liner.
The membrane, which allows the proper amount of airflow and pressure through your product package, is a semi-permeable material that's manufactured to let your package breathe and increase its life expectancy. It can be manufactured to be hydrophobic (water repellent) or oleophobic (oil repellent).
Cap liners and seals are both used to protect products and improve their shelf life. While the terms 'cap liner' and 'seal' are often used interchangeably, it is important to remember that a seal can be defined in multiple ways. For example, in addition to the protective seal on a bottle, a seal can also be defined as the plastic tamper-evident wrap on the outside of a bottle, or the tape that seals a box or other container shut. In this article, we will use the term to refer to the protective film that protects the content inside of a container from leakage and contaminants, either by sealing directly to the opening of the container or by creating a barrier from inside of the closure.
A cap liner may not be the first component you consider when designing a new package, but this often-overlooked item provides a big solution to protecting your product. In this article, we'll discuss the differences between cap liners and seals in more detail. We'll also provide some tips on how to choose the right one for your product.
