Liner system replaces traditional round paperboard-backed foil liners that are
prone to curling, as well as tri-tab liners that forestall
curling, but may distort eddy currents during induction
sealing, thus compromising seal integrity. Five
protruding extensions hold Lockliner cap liner in place
so it doesn’t bow, bend, creep, curl or blow-out of
closure during shipping or warehousing. At same time,
design minimizes disruption of eddy currents during
induction sealing because tabs cover larger area around
perimeter, measuring roughly twice as wide as tri-tab
extensions, but 66% shorter. Transition to Lockliner cap
liner requires no adjustments to existing capping or
induction sealing equipment. Innovative Molding
supplies Lockliner cap liners for 110-millimetre (mm)-
diameter caps, plans to offer additional sizes as small
as 63mm. Options include paperboard-backed foil as
well as synthetic-backed constructions suitable for liquid or dry products, hot or ambient
fills, plastic or glass containers.

Striking pearl red high-density polyethylene (HDPE) bottle
accommodates different closure styles to handle wide array of
products.
Continental Packaging Solutions, Chicago, IL, develops 8-
ounce torpedo-shaped container with 28-400 polypropylene closure
for transmission or brake fluid. However, compatibility with wide array
of closures such as push-pull caps, trigger sprayers, extends potential
applications far beyond automotive world. Continental plans to add 16-
, 24-, 32-ounce sizes, could engineer new molds to produce custom
sizes.
