Material storage and dispensing packages and methods

A material containment package including a first liner having an interior volume adapted to hold a first material therein in a sealed condition, and a second liner having an interior volume adapted to hold the first liner therein, wherein each of the first and second liners has a fitment allowing fluid communication with its interior volume, wherein the fitment of the first liner is coupleable with the fitment of the second liner to form a fitment assembly for the package.

A composite liner including a primary liner attached at an upper end thereof to a fitment providing material introduction and removal communication with an internal volume of the primary liner, and a secondary liner partially penetrating and secured to the primary liner with a penetrated portion of the secondary liner disposed in the internal volume of the primary liner, said secondary liner including a non-penetrating portion exterior of the primary liner, wherein said penetrated portion of the secondary liner is gas-permeable but liquid-impermeable.

A liquid medium storage and dispensing package, comprising a container having an interior volume for holding liquid medium, said container including a semi-flexible portion that is shape-shiftable to vary size of said interior volume available to hold the liquid medium, whereby the interior volume is selectively variable between an expanded volumetric state providing a greater head space for said liquid medium and a compacted volumetric state providing a smaller head space for said liquid medium.

A polymeric film laminate, comprising an inner ply formed of high purity medium density polyethylene, and an outer ply including seven film layers comprising successively a first layer, adjacent the inner ply, of linear low density polyethylene and medium density polyethylene including an anti-block agent, a first tie layer of anhydride-modified polyethylene adjacent the first layer, a first polyamide layer adjacent the anhydride-modified polyethylene tie layer, an EVOH layer adjacent the first polyamide layer, a second layer of polyamide adjacent the EVOH layer on a side thereof opposite the side adjacent the first polyamide layer, a second tie layer of anhydride-modified polyethylene adjacent the second polyamide layer, and a layer of linear low density polyethylene and high density polyethylene including an anti-block agent.
