Abstract
The present invention relates to a flat, multilayered, low moisture, barrier, laminated thermoplastic film with an absorptive food contact layer coated with a flavoring and/or coloring agent, which can be formed on automatic stuffing machinery into a sealed tube in a continuous manner for use as a food casing. This film has an absorptive food contact layer, an oxygen barrier layer, and a polyethylene outer layer. The coloring and/or flavoring agent on the absorptive layer is released onto the surface of encased foodstuff during cooking and processing.
Claims26
A multilayered film, comprising:
- a first outer absorbent layer, comprising:
- absorptive material selected from the group consisting of;
- polyethylene terephthalate (PET) paper;
- cellulose and polyester blend paper;
- papers made from noncellulosic materials;
- and pressed, matted, or felted fibrous papers;
- and
- a solution absorbed within the absorptive material, the solution comprising a peeling aid and a selection from the group consisting of a coloring solution, a flavoring solution, and a coloring and flavoring solution;
- a second inner thermoplastic layer comprising an oxygen barrier;
- and
- a third outer thermoplastic layer comprising a moisture barrier and abuse resistant layer,
- the Kinetic Coefficient of Friction of the third outer thermoplastic layer to metal being a maximum of 0.425,
- the Kinetic Coefficient of Friction of the first outer absorbent layer to metal being a maximum of 0.400,
- the Kinetic Coefficient of Friction of the first outer absorbent layer to the third outer thermoplastic layer being a maximum of 0.425,
- the multilayered film being a flat film, and
- the multilayered film being a dry film with a finished moisture level from 2.0 wt. % to 5.0 wt. % of the multilayered film.
