Abstract
A flexible material for a flexible container can include a first laminate and a second laminate joined to at least a portion of the first laminate by at least one seal. The first laminate can include a first gas barrier layer disposed between first and second sealable layers, wherein the first and second sealable layers define opposed exterior layers of the first laminate. The second laminate can include a third sealable layer defining an exterior layer of the second laminate, and a second gas barrier layer. The at least one seal joins a portion of the third sealable layer to at least a portion of the second sealable layer.
Claims19
A flexible material for a flexible container comprising a structural support volume and a product volume, the flexible material comprising:
- a first laminate comprising, in order:
- a first sealable layer, which is linear low-density polyethylene, and which defines an exterior layer of the first laminate;
- a first tie layer;
- a first reinforcing layer, which is nylon;
- a first gas barrier layer, which is ethyl vinyl alcohol;
- a second reinforcing layer, which is nylon;
- a second tie layer;
- and
- a second sealable layer, which is linear low-density polyethylene, and which defines an exterior layer of the first laminate;
- and
- a second laminate comprising, in order:
- a third sealable layer, which defines an exterior layer of the second laminate;
- a second gas barrier layer, which is ethyl vinyl alcohol;
- a print layer, which has a surface that includes ink, and which defines an exterior layer of the second laminate;
- wherein:
- at least a portion of the third sealable layer joins to at least a portion of the second sealable layer such that the joined portions form at least one seal that defines at least one boundary of the structural support volume, which is disposed between the first and second laminates, and
- in at least a structural support volume forming region of the flexible material, the flexible material has a gas transmission rate of about 0.05 cc/m2·day·atm to about 18 cc/m2·day·atm.
