Choosing the Correct Cap Liner

Screw-Caps_Glamour_PKG_wht

When choosing the correct container, experts typically know exactly what they are looking for and what they require for their applications. However, when choosing the closure, one small detail is often overlooked. The liner of a closure may seem like an insignificant matter, but it serves a very important purpose; to maintain the integrity of the container-cap system. The correct liner should be chosen depending on the contents of the container.

If the improper liner is chosen, than the liner can adversely affect the outcomes of the work. The liner is used to seal the product inside the container and should be able to tolerate many applications and removals without any negative effects on the product. The choice of liner material depends on many different factors such as the acidity, temperature, barrier properties, resistance properties, stress factors, and other conditional requirements. All of these factors play major roles in identifying which liner is most suitable for a specific situation and application. Wheaton’s Closure Liner Guide is a great resource to reference when you’re unsure of the correct liner for your application.
