Abstract
A disposable paper pouch enclosing a food product, the pouch being both biodegradable and recyclable. The pouch is made up of two superposed paper plies which are rendered liquid impervious by water-based acrylic layers coated on the inner and outer faces of the plies, the acrylic inner layer having a low melting temperature and the acrylic outer layer having a high melting temperature. The superposed plies are subjected to heat and pressure by standard sealing bars that have no effect on the outer layers but cause the inner layers which face each other to fuse together in a predetermined sealing pattern to define an inner pocket that is fillable with the food product.
