What type of liners for bottle caps do you offer?

Liners can be confusing…here is the information that we have compiled on the types of liners that come with our various products.

1. F217 has a low density foam core between two solid layers of low density polyethylene. F217 has excellent odor resistance and chemical resistance. Application: General purpose. Used to seal cosmetics, liquors, drugs, foods and other products. If something says that it has a PE liner, this is probably the type of liner it has. This is a very common liner. You will see these on many of our products, most commonly on ribbed polypropylene caps.

2. The Poly-cone liner is a cone shape LDPE liner. You will see it listed as “P”.  We offer this type of liner with some of our glass bottles and jars.

3.  The PVLF liner is a pulp and vinyl lubricated film. A poly-vinyl coating is applied to a pulp paper backing. You will see it listed as “PV”.  It is a good liner type for chemical resistance. We offer this type of liner with some of our glass bottles and jars.

PS = Pressure Sensitive (PS 22 or PS 113):
Pressure Sensitive adhesive, coated on polystyrene foam liner, with one adhesive side that sticks to the container. Pressure is applied to the closure which allows for the liner to adhere to the container. When the closure is removed the pressure sensitive liner remains on the top of the container, leaving a sealed for your protection seal on the container.

4. PS22 liners are pressure sensitive, coated on polystyrene foam. A PS22 liner is made of .020” thick polystyrene foam disc with an EVA-wax type adhesive that is released when the closure is properly torqued onto the container. The liner is designed to stay in place even after the cap has been removed. These liners will adhere to both plastic and glass bottles and jars. These liners provide a one-time seal to be removed by the end user. The benefit of this type of cap is that no secondary equipment is required to apply them. While these seals when properly applied can create a moisture barrier for keeping products inside dry, they are not considered by the FDA to be tamper evident. Suggested Product Uses: dry products, pharmaceuticals, nutraceuticals, candy, and spices. We offer a line of Polypropylene caps with these type of liners.
5. PS113 pressure sensitive adhesive coated on polystyrene foam. These liners come in some of the caps that we offer for our spice jars.

Induction Liner = Heat Induction Seal Liner (SG 75 and others): A liner with a specialized laminate containing aluminum foil and a plastic heat sealable film that seals to a container through the use of an heat induction machine. The induction machine produces an electromagnetic current which adheres the foil lining on to the container which makes an air tight seal between the liner and the container.

6. SG 75 Heat Induction Liner - An innerseal which provides a fused, tamper indicating seal on P/E containers. It is designed for use in plastic closures. It is white lined pulpboard wax-bonded to an innerseal consisting of .001" aluminum foil with a .002" heat sealable polyester film. The SG75 liners offers excellent chemical resistance and superior barrier properties as well as a tough durable seal. It has broad market acceptance for use with industrial chemicals, automotive products, pharmaceutical and food products. Typical packaging applications include innerseals for orange juice, patent drugs, windshield washer solution, anti-freeze, motor oil, household cleaners, insecticides, herbicides, etc.  We offer these liners in the white and black ribbed caps.

7. Unlined = No Liner: A closure with no special sealing features and no liner.
