Abstract
A packaged liquid-filled plastic tube is provided to achieve a desirably long shelf life. The tube is formed from PET, polypropylene or otherknown plastics that exhibit high liquid permeability. A liquid additive of a specified volume, concentration and/or solubility is placed in the tube and the tube is sealed. Loss of liquid through the permeable tube is prevented by a moisture barrier film that is sealed around the tube. The moisture barrier film maintains a high relative humidity adjacent said tube and substantially minimizes transport of liquid vapor through the plastic of the tube.
Claims15
Packaging for liquids of specified volume, concentration and solubility, said packaging comprising:
- at least one plastic container having a closed bottom, an open top and a side wall extending therebetween, said liquid of said specified volume, concentration and solubility being placed in said container, a closure sealingly engaged with said open top of said container for retaining said liquid therein, a moisture barrier film completely surrounding said container for preventing vapor transport across said film and maintaining a selected relative humidity between said container and said film for substantially preventing permeation of said liquid from said container.
A method for packaging liquids to maintain a specified volume, concentration and solubility, said method comprising:
- providing a plastic container having a closed bottom, an open top and a side wall extending therebetween;
- depositing in said plastic container said liquid of said specified volume, concentration and solubility;
- sealingly enganging a closure with said open top of said container for retaining said liquid therein;
- providing a moisture barrier film completely around said plastic container and said closure for preventing vapor transport across said film and maintaining a selected relative humidity between said container and said film for substantially preventing permeation of said liquid from said container.
