Laminated paperboard packaging and method of manufacturing the same

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.

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.

[0010]In another embodiment of the present invention, a laminated packaging material comprises 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

Problems solved by technology

However, many of the current commonly-used packaging materials suffer mechanical failures and many other threats to the integrity of the structure during the course of normal operating conditions, such as saturation, which leads to deterioration of the integrity of the packaging material, and an eventual failure of the package to achieve its intended purpose.

Additionally, attempted solutions to this problem are not strong enough to maintain the structural integrity of the packaging material as the thin structures embodied in known containers are subjected to long term wear on the packaging.

However, the polyethylene coating does not effectively resist the diffusion of water into the paper after a significant period of time.

Additionally, polyethylene offers little resistance to heat, making the packaged ice cream or frozen novelty more susceptible to certain conditions, especially normal environmental temperatures.
