Description
Applications
Foamed Polyethylene
(PE Foam)
A one piece, three ply coextruded liner consisting of both
foamed and solid LDPE. The foam core is sandwiched with
solid clear PE.
General Purpose: Broad applications base. Good chemical resistance to acids,
alkalis, solvents, alcohols, oils, household cosmetics and aqueous products.
Poor for hydrocarbon solvents. Liner provides tight seal.
Pulp / Metal Foil
Aluminum foil bonded to pulp board.
Good barrier properties and resistance to hydrocarbons, oils, ketones and
alcohols. Not good for acids or alkalis.
Polyethylene Cone
(PE Cone)
Manufactured from polyethylene (LDPE). The unique cone
design provides a wedge type seal that not only seals across
the top but also across the inside diameter.
Unique problem solving type of liner. This liner is stress crack resistant and
offers superior torque retention and excellent sealing characteristics. It is
recommended that this liner be tested prior to use for leak seal.
Note: Closures and liners are designed for a variety of applications. Product performance can vary depending on conditions. It is recommended that proper tests
be performed to determine the best liner for the application.
