Poly-Vinyl : A poly-vinyl film adhered to a white pulp paper backing. It is a good liner type for
chemical resistance, mild acids, alkalis, solvents, alcohols, oils
and aqueous products; not recommended for active hydrocarbons or bleaches.
F217 : a three-ply material. F217
has a low density foam core between two solid layers of low density
polyethylene. F217 has excellent chemical resistance and low moisture
transmission rate. F217 also has good taste and odor resistance.
PS 22 : A pressure sensitive foam
liner with one adhesive side that sticks to the container with the
pressure used to place the closure on the container. When the closure
is remove the pressure sensitive liner remains on the top of the
container.
Induction liner: A
specialized laminate containing aluminum foil and a plastic heat
sealable film that hermetically seals to a container through the
use of a machine that produces an electromagnetic current which
releases the foil lining on to the container achieving a tight
seal. Induction liners are available with pull tabs and pealable versions so not to leave residue on the container once removed.
Foamed Polyethylene : A good
general-purpose liner material. It has a broad application base,
chemical resistance, good for acids, alkalis, solvents, alcohols,
oils household cosmetics and aqueous products. It is fairly poor
for hydrocarbon solvents.
Poly-Seal cone lined ™ : Made out of LDPE plastic, the poly-seal cone lined cap provides a wedge type seal that not only seals across the top of the container, it also seals across the inside diameter. This liner is stress crack resistant and offers
superior torque retention and excellent sealing characteristics.
This liner is commonly used for liquid products. This liner should be tested first to make sure leaking does not occur.
Teflon Faced Foamed Polyethylene : A teflon lined foamed polyethylene that has excellent chemical resistance of teflon with the compressibility and sealing properties of polyethylene foam. Typical
uses of teflon faced foamed polyethylene included: analytical
lab samples, high purity chemicals, strong acids solvents. Uses
included environmental samples, pharmaceuticals, and diagnostic
reagents.
Pulp Metal Foil : A polyester film laminated to aluminum foil, bonded to pulp board. Pulp metal foil
liners have good barrier properties, as well good resistant to hydro
carbonates, oils, ketones and alcohols, the pulp metal foil liner
is not recommended for acids or alkalis.
If you are looking for a closure with a certain liner and don’t
see one that fits your needs in our cap
index, then let us know. >>
