Metal, continuous thread cap with neck finish and a .040" F-217. Commonly used on glass bottles or jars, and jugs. They can also be used with lotion, soaps, creams, and personal care items. Continuous thread caps are popular in a wide range of wholesale industries from food, personal care, pet care, household products, industrial products, health and beauty, arts, crafts, hobbies and just about any other market segment. Aluminum closures are lightweight and can tolerate various temperatures. They are also resistant to impact fractures. They are applicable with products in high humidity environments, high salt content products, or water.
F-217 liners are made of three layers, a thin foam core is placed between two layers of LDPE film. While F-217 liners are commonly referred to as foam liners, they tend to perform better than a regular foam liner. F-217 and foam liners do not create airtight seals. Liners are an important aspect of every continuous thread cap and products should best tested with the cap to determine which liner will be the best fit. Discontinued
