Layered product for packaging

Abstract

A packaging material being a laminate formed by an outer layer comprising a laminated film which in turn is constituted by a cellophane sheet and easy-to-cut plastic film, and an inner layer comprising hot-melt material coating, wherein said packaging material allows for easy manufacturing control and storage control and offers good cutting properties in all directions when cut while a block of cheese or other food is packaged inside.

1 . A layered product for packaging characterized in that an outer layer is formed of a laminate film of a cellophane sheet and easy-to-cut plastic film, and an inner layer is formed of a hot-melt material. 
     
     
         2 . The layered product for packaging according to  claim 1 , characterized in that the easy-to-cut plastic film that forms the outer layer is constituted by polyester. 
     
     
         3 . The layered product for packaging according to  claim 1 , characterized in that the easy-to-cut plastic film that forms the outer layer is constituted by a three-layer structure which is formed of polyester comprising a physically brittle layer as a middle layer, and/or which is formed of polyester having a film surface physically embrittled by mechanically scratching the film surface. 
     
     
         4 . The layered product for packaging according to  claim 1 , characterized in that the hot-melt material that forms the inner layer is coated with 10 to 40 g/m 2 . 
     
     
         5 . The layered product for packaging according to  claim 2 , characterized in that the hot-melt material that forms the inner layer is coated with 10 to 40 g/m 2 . 
     
     
         6 . The layered product for packaging according to  claim 3 , characterized in that the hot-melt material that forms the inner layer is coated with 10 to 40 g/m 2 . 
     
     
         7 . A knife-cuttable layered product for food packaging, comprising:
 a laminate consisting of a cellophane sheet and an easy-to-cut polyester film, said easy-to-cut polyester film comprising a physically embrittled polyester layer; and   a hot-melt coating coated on a surface of the easy-to-cut polyester film in an amount of 10 to 40 g/m 2 , said hot-melt coating being adapted to be in immediate contact with food packaged by the layered product.   
     
     
         8 . The layered product for food packaging according to  claim 7 , wherein the easy-to-cut polyester film comprises other polyester layers, and the physically embrittled polyester layer which is more brittle than the other polyester layers is a middle layer sandwiched between the other polyester layers. 
     
     
         9 . The layered product for food packaging according to  claim 7 , wherein the easy-to-cut polyester film is a polyester film having a surface mechanically scratched without penetrating through the polyester film, so as to embrittle the polyester film. 
     
     
         10 . The layered product for food packaging according to  claim 7 , which consists of the laminate and the hot-melt coating. 
     
     
         11 . A packaged food, comprising:
 the knife-cuttable layered product according to  claim 7 ; and   a food packaged by the layered product wherein the food is in immediate contact with the hot-melt coating,   wherein the layered product is cuttable in multiple directions for each serving with the food packaged inside, using a kitchen knife or pocketknife.   
     
     
         12 . The packaged food according to  claim 11 , wherein the food is selected from the groups consisting of cheese, sweet bean jelly, and rice powder jelly. 
     
     
         13 . The packaged food according to  claim 11 , wherein the easy-to-cut polyester film comprises other polyester layers, and the physically embrittled polyester layer which is more brittle than the other polyester layers is a middle layer sandwiched between the other polyester layers. 
     
     
         14 . The packaged food according to  claim 11 , wherein the easy-to-cut polyester film is a polyester film having a surface mechanically scratched without penetrating through the polyester film, so as to embrittle the polyester film. 
     
     
         15 . The packaged food according to  claim 11 , wherein the layered product consists of the laminate and the hot-melt coating.
