GORE Liner Vents for Pressure Equalization in Sealed Packaging

Easy, Economical Integration. No Cap Modification

GORE Liners easily convert non-vented containers into vented containers without modifying the existing cap or closure. They are available in two series – Foam Liners and Pulp Induction Liners and provide unprecedented performance for the extreme challenges faced by fertilizers, pesticides, household chemicals and cleaners.

GORE Induction Liner White Membrane & Foam Liner

Benefits of Liners:

Easy to integrate without re-design of cap.
Designed for cap-thread venting or hole-in-cap venting.
Available in single- and multi-up rolls in a range of widths
Cut parts can also be provided

GORE Liners are developed for fertilizer, pesticides, household chemicals and cleaners.

More specifically:

Foam Liners: Two Series, with full-surface membranes, for all flat-cap designs. Easy drop-in replacements for all single-point or unvented liners, in applications from consumer chemicals to DOT and ADR-regulated packaging.
Pulp Induction Liners: Two Series, for agrochemical bottles (up to 20 l). Weldable installation ensures tamper-evidence; membrane construction provides needed breathability for gas-scavenging chemicals and off-gassing liquids.

The portfolio of GORE Liners include GORE Foam Liners and GORE Pulp Induction Liners.

GORE Foam Liners

Gore Foam Liners reliably vent hazardous chemicals, agrochemicals, liquid fertilizers, institutional cleaners and household chemicals.

Easy drop-in replacements for all single-point or unvented liners.
Choose Standard Series or High Performance Series for more challenging chemistries.
Full-surface construction, outperforming single-point liners, increases liquid repellency and residual airflow.
More reliable leak-resistance during transport and handling, due to improved Water Entry Pressure (WEP) resistance and competitive levels of Liquid Entry Pressure (LEP) resistance in most standard applications.
For all flat-cap designs in applications from consumer chemicals to DOT and ADR-regulated packaging.

Gore Pulp Induction Liners

Gore Pulp Induction Liners provide reliable venting and tamper-evidence for agrochemicals including organic biostimulants.

For agrochemical bottles (up to 5 l).
Choose Standard Series or High Performance Series for more extreme chemistries or greater flow.
Weldable installation ensures tamper-evidence.
Membrane construction provides needed breathability for gas-scavenging chemicals and off-gassing liquids.

GORE Foam Liner, High Roll-Off Series has been tested for both extremely high WEP resistance and unprecedented LEP resistance to a wide variety of formulations with varied surface tensions and viscosities.
WEP measures a vent’s leak-resistance to water.

WEP measures a vent’s leak resistance to other liquids – which typically have surface tension much lower than water, so they may more easily penetrate the vent, even though water would not. LEP resistance to a given fluid is critical to preventing leaks in real-world conditions – as when a container falls over in transport or handling.
