GORE Foam Liner: High Roll-Off Series - Our Highest Protection for Your Most Demanding Applications

GORE Foam Liners High Roll-Off Series (3FL-363G) delivers unprecedented venting performance, to enhance the safety of your most hazardous formulations in the most challenging circumstances.

GORE® Packaging Vents’ new High Roll-Off Series puts our most advanced membrane technology in a full-surface foam liner, to achieve a new level of resistance to container deformation and leaks.

The High Roll-Off Series means greater confidence in package integrity, and greater peace of mind about safety – especially for applications where your most hazardous or aggressive chemicals, agrochemicals, institutional cleaners or household chemicals are exposed to the most extreme conditions during storage, transport or handling.

 

A new standard for airflow

  • Outstanding roll-off characteristics deliver unprecedented ‘residual airflow’ (after contact with even the most aggressive liquids), due to a proprietary, roll-off optimized GORE™ Membrane that was designed to keep packaging safe and intact over its lifetime.
  • Full-surface construction delivers very high ‘initial airflow’ (prior to liquid contact), because the breathable GORE™ Membrane extends across the whole surface of the liner and promotes more rapid, continuous pressure equalization.

 

 

About WEP and LEP

WEP measures a vent’s leak-resistance to water. LEP 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. Gore‘s 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.

A new achievement in liquid resistance

  • Unprecedented Liquid Entry Pressure (LEP) resistance means greater leak-resistance during shipping and handling, especially for very aggressive, viscous or low surface-tension liquids that defeat other vents.
  • Extremely high Water Entry Pressure (WEP) resistance outperforms our prior technologies and complies with high regulatory standards.

 

For added peace of mind AND productivity

The new High Roll-Off Series truly is one solution for the most aggressive chemicals, for the most challenging real-world conditions, and for all flat cap designs.

  • Chemical manufacturers can feel more confident about the security of their hazardous, high-viscosity or low surface-tension formulations all along the supply chain, because the new High Roll-Off Series offers unprecedented performance and protection.
  • Cap and container manufacturers can streamline logistics and inventory, since the High Roll-Off Series is a drop-in replacement for other liners in all flat-cap designs, in a wide variety of applications.

The new GORE Foam Liner High Roll-Off Series (3FL-363G) is available as single-and multi-up roll goods, in various widths. Cut parts can also be offered.
