Formed article and method of use

Abstract

A formed article includes a rigid film, a liner film, and a cavity. The rigid film includes a thickness and a line of weakness. The rigid film and the liner film are joined to each other. Further, the line of weakness is positioned in the cavity. The formed article is configured to facilitate separation (e.g., peeling) of the rigid film from the liner film.

1 . A formed article comprising:
 a rigid film comprising a thickness and a line of weakness;   a liner film; and   a cavity;   wherein the rigid film and the liner film are joined to each other; and wherein the line of weakness is positioned in the cavity.   
     
     
         2 . The formed article of  claim 1 , further comprising a flange, wherein the line of weakness comprises a length from a point on the flange to an opposing point on the flange. 
     
     
         3 . The formed article of  claim 1 , wherein the line of weakness comprises a depth, and wherein the depth of the line of weakness is less than or equal to the thickness of the rigid film. 
     
     
         4 . The formed article of  claim 1 , wherein the line of weakness comprises at least one of a cut, a perforation and a score. 
     
     
         5 . The formed article of  claim 1 , wherein the line of weakness is provided in the rigid film before forming of the cavity. 
     
     
         6 . The formed article of  claim 1 , further comprising an additional film, wherein the additional film is joined to the liner film opposite to the rigid film. 
     
     
         7 . The formed article of  claim 6 , wherein the additional film comprises a thickness equal to or less than the thickness of the rigid film. 
     
     
         8 . The formed article of  claim 6 , wherein the additional film comprises one or more of amorphous polyester (APET), crystalline polyester (CPET), olefin-based materials, polystyrene, and polylactic acid (PLA). 
     
     
         9 . The formed article of  claim 1 , wherein the rigid film comprises one or more of amorphous polyester (APET), crystalline polyester (CPET), olefin-based materials, polystyrene, and polylactic acid (PLA). 
     
     
         10 . The formed article of  claim 1 , wherein the liner film comprises at least one of ethylene vinyl alcohol (EVOH) and high-density polyethylene (HDPE). 
     
     
         11 . The formed article of  claim 1 , wherein the liner film further comprises a compatibilizer. 
     
     
         12 . The formed article of  claim 1 , wherein the liner film comprises a barrier material. 
     
     
         13 . The formed article of  claim 1 , wherein a bond strength between the rigid film and the liner film is greater than or equal to 50 g/25.4 mm. 
     
     
         14 . The formed article of  claim 1 , further comprising a lidding component. 
     
     
         15 . The formed article of  claim 1 , wherein the line of weakness is centrally positioned along a length of the rigid film. 
     
     
         16 . The formed article of  claim 1 , wherein a material of the rigid film and a material of the liner film have different recycling profiles. 
     
     
         17 . A method for removing a rigid film from a liner film of a formed article, the formed article comprising the rigid film comprising a thickness and a line of weakness; the liner film; and a cavity; wherein the rigid film and the liner film are joined to each other; and wherein the line of weakness is positioned in the cavity; the method comprising the steps of:
 supplying the formed article;   subjecting the formed article to a fracturing energy that separates the rigid film into a first segment and a second segment at the line of weakness; and   grasping the first segment and the second segment of the rigid film to peelably remove the first segment and the second segment from the liner film.   
     
     
         18 . A formed article comprising:
 a rigid film comprising a thickness, a length and a line of weakness, the line of weakness comprising a depth less than or equal to the thickness of the rigid film, wherein the line of weakness extends perpendicular to the length of the rigid film;   a liner film; and   a cavity;   wherein the rigid film and the liner film are joined to each other, wherein the line of weakness is positioned in the cavity.   
     
     
         19 . The formed article of  claim 18 , further comprising a flange, wherein the line of weakness comprises a length from a point on the flange to an opposing point on the flange. 
     
     
         20 . The formed article of  claim 18 , further comprising an additional film, wherein the additional film is joined to the liner film opposite to the rigid film.
