Cap Liner Types and Functions

Choosing a liner type and style is one of the most important factors of cap selection. Certain products such as chemicals, consumer products or foods may require specialized liners. Different liner materials may be used for moisture barriers, chemical resistance, consumer safety, or preventing leakage. Depending on the material, cap liners may also influence the cost of your finished product. As always, be sure to test your product with the liner you choose to be sure they are compatible. If you have questions or would like to perform compatibility tests, please contact us with your liner requirements by emailing [email protected].

• Unlined : common for candle, other dry products that doesn’t require a liner
• Pulp & Poly : Pulp and Poly liners have two components: a thin film (polyvinyl) attached to a paper (pulp) material. Common with Concentrated Coffee, Beverages, Juice, Dry Health Foods, Honey, Syrup, etc.
• Pulp & Vinyl : A pulp / poly liner consists of a poly-vinyl film adhered to a white pulp paper backing. Chemical resistance to mild acids, alkalis, solvents, alcohols, oils and aqueous products.
• Poly & Aluminum : A polyester film laminated to aluminum foil, bonded to pulp board. Common for cosmetic creams, personal care products, and automative oils, or other vegetable cooking oils
• PS22 – Pressure Sensitive : A pressure sensitive foam liner with one adhesive side that sticks to the container with the pressure used to secure the closure onto the container. When the closure is removed, the pressure sensitive liner remains on the top of the container. Common for dry products, pharmaceuticals, vitamins, and supplements
• HS035 – Heat Induction : Induction liners have several layers: pulpboard, wax, foil, and a polymer coating. When passed through an induction machine, the heated foil melts the wax and polymer, creating a hermetic seal with the container when solidified. Common for food, sauce, and other products requiring a seal for consumer confidence
• Plastisol : A plastic gasket on the inside of a metal closure that creates an airtight seal with the container when properly heated and cooled. Common for hot fill food and beverage items, sauce and other liquid form items.
