Sustainable packaging system for shipping liquid or viscous products

摘要

The present disclosure, in one embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material. The packaging assembly includes a carton having side and bottom walls. The packaging assembly also includes a self-supporting plastic liner that fits inside of the carton for containing liquids, viscous material, or particulate material. The liner has either a substantially circular or substantially oval cylindrical side wall, a closed bottom end characterized by a bottom wall formed integral with said side wall, and an open top end having an outwardly-projecting rim. The rim has a radially-extending flange portion, and a dependent skirt portion, wherein when the self-supporting plastic liner is inside of the carton, the radially extending flange portion supports the liner on at least a portion of the carton. A lidding material is provided to seal the plastic liner.
