Abstract
Embodiments of the present invention generally relate to a laminated composite paperboard packaging for containing ice cream and a method of manufacturing the same. In one embodiment of the present invention, a laminated packaging material comprises a layer of paperboard, a layer of an aqueous coating disposed on a first surface of the layer of paperboard, and a layer of a thermoplastic resin disposed on a second surface of the layer of paperboard, wherein the laminated packaging material has a water vapor transmission rate of less than 20 grams per square meter per twenty-four hours in an environment of about 100 degrees Fahrenheit and 90% humidity.
Claims32
A laminated packaging material comprising:
- a layer of paperboard;
- a layer of an aqueous coating disposed on a first surface of the layer of paperboard;
- and
- a layer of a thermoplastic resin disposed on a second surface of the layer of paperboard;
- wherein the laminated packaging material has a water vapor transmission rate of less than 20 grams per square meter per twenty-four hours in an environment of about 100 degrees Fahrenheit and 90% humidity.
A laminated packaging material comprising:
- a layer of paperboard;
- a layer of linerboard;
- a first layer of a thermoplastic resin disposed between a first surface of the layer of linerboard and a second surface of a layer of paperboard;
- a layer of an aqueous coating disposed on a first surface of the layer of paperboard;
- and
- a second layer of a thermoplastic resin disposed on a second surface of the layer of linerboard;
- wherein the laminated packaging material has a water vapor transmission rate of less than 20 grams per square meter per twenty-four hours in an environment of about 100 degrees Fahrenheit and 90% humidity.
An ice-cream package comprising:
- a cylindrical sidewall;
- and
- a bottom wall comprising:
- a layer of paperboard;
- a layer of an aqueous coating disposed on a first surface of the layer of paperboard;
- and
- a first layer of a thermoplastic resin disposed on a second surface of the layer of paperboard;
- wherein the laminated packaging material has a water vapor transmission rate of less than 20 grams per square meter per twenty-four hours in an environment of about 100 degrees Fahrenheit and 90% humidity;
- wherein the bottom wall is bonded to the bottom portion of the cylindrical sidewall.
The ice-cream package of claim 18, wherein the layer of a thermoplastic resin comprises low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), polypropylene (PP), any copolymer thereof, or any combination thereof.
A package comprising
- a container including a bottom wall and a side wall extending upwardly from the bottom wall and forming an inside portion above the bottom wall and
- a laminated packaging material located in the inside portion of the side wall and arranged to cover the bottom wall and cooperate with the side wall to form an ice cream-storage region above the bottom wall, wherein the laminated packaging material includes
- a layer of paperboard having a lower surface facing toward the bottom wall and an upper surface facing away from the bottom wall toward any ice cream extant in the ice cream-storage region,
- a layer of thermoplastic resin disposed on the lower surface of the layer of paperboard to lie between the layer of paperboard and the bottom wall, and
- a layer of an aqueous coating disposed on the upper surface of the layer of paperboard to lie between any ice cream extant in the ice cream-storage region and the layer of paperboard, and wherein the layers of an aqueous coating, paperboard, and thermoplastic resin cooperate to provide the laminated packaging material with a water vapor transmission rate of less than twenty grams per square meter per twenty-four hours in an environment of about 100° Fahrenheit and 90% humidity.
