Abstract
A barrier tape comprises a barrier section comprising one or more barrier layers and one or more adhesive layers adhered to a face of the barrier section. The barrier tape can be used to join together adjacent barrier sheets or to patch a breach in a barrier sheet to form a barrier assembly.
Claims19
A barrier assembly comprising:
- a flat or substantially flat first barrier film;
- and
- one or more pieces of barrier tape affixed to the first barrier film, each piece of the barrier tape comprising:
- a barrier section comprising one or more inner polar tape layers each formed predominantly from ethylene vinyl alcohol and a pair of outer non-polar tape layers each formed predominantly from polyethylene, wherein a first of the pair of outer non-polar tape layers is positioned on a first side of the one or more inner polar tape layers and a second of the pair of outer non-polar tape layers is positioned on a second side of the one or more inner polar tape layers;
- a pair of tape tie layers each formed predominantly from polyethylene grafted with maleic anhydride, each of the pair of tape tie layers being positioned between the one or more inner polar tape layers and a corresponding one of the pair of outer non-polar tape layers;
- and
- one or more adhesive layers adhered to a face of the barrier section.

- a pair of film tie layers each formed predominantly from polyethylene grafted with maleic anhydride, each of the pair of film tie layers being positioned between the one or more inner polar film layers and a corresponding one of the pair of outer non-polar film layers;
- and
- wherein each of the one or more pieces of the barrier tape comprises:
- a tape barrier section comprising one or more polar barrier layers and one or more non-polar barrier layers;
- and
- one or more adhesive layers adhered to a face of the barrier section.
