Acrylate composite barrier coating

A container comprising:

• a closable hollow container molded from a thermoplastic selected from the class consisting of polypropylene, polyethylene, polyester and nylon;
• a first vapor deposited, crosslinked acrylate layer on the outside of the container, the outside surface of the container being sufficiently smooth that the acrylate layer is continuous;
• a substantially continuous layer of gas barrier material vacuum deposited over the acrylate layer;
• and
• a second vapor deposited acrylate layer over the gas barrier layer which was crosslinked before the gas barrier material contacted any solid surface.

A gas barrier sheet comprising:

• a thermoplastic sheet substrate;
• a substantially continuous layer of gas barrier material vacuum deposited on one face of the sheet substrate;
• and
• an evaporated acrylate layer deposited over the gas barrier layer and crosslinked before the gas barrier material contacts any solid surface.

A barrier sheet comprising:

• a thermoplastic substrate;
• a first vapor deposited, crosslinked acrylate layer on one face of the substrate;
• a substantially continuous layer of gas barrier material vacuum deposited over the acrylate layer;
• and
• a second vapor deposited acrylate layer over the gas barrier material which was crosslinked before the gas barrier material contacted any solid surface.

A barrier sheet comprising:

• a thermoplastic substrate;
• a first vapor deposited, crosslinked acrylate layer on one face of the substrate;
• a substantially continuous layer of gas barrier material vacuum deposited over the acrylate layer, wherein the gas barrier material layer is transparent;
• and
• a second vapor deposited acrylate layer over the gas barrier material which was crosslinked before the gas barrier material contacted any solid surface.

A barrier sheet made in a continuous in-line process comprising:

• a thermoplastic substrate;
• a first vapor deposited, crosslinked acrylate layer on one face of the substrate;
• a substantially continuous layer of gas barrier material vacuum deposited in the in-line process over the acrylate layer;
• and
• a second vapor deposited acrylate layer over the gas barrier material which was crosslinked before the gas barrier material contacted any solid surface.

A barrier sheet made in a moving web process comprising:

• a thermoplastic moving web substrate;
• a first vapor deposited, crosslinked acrylate layer on one face of the substrate;
• a substantially continuous layer of gas barrier material vacuum deposited in the moving web process over the acrylate layer;
• and
• a second vapor deposited acrylate layer over the gas barrier material which was crosslinked before the gas barrier material contacted any solid surface.
