For the first time in six years of promises, a permanent clean water supply is likely to be built soon for residents affected by contamination leaching into groundwater from Ivy Industrial Park.

A settlement announced Friday between the Department of Environmental Protection and industrial park tenants Bostik Inc. and Sandvik Inc. has given the more than 200 affected property owners confidence that a long-term solution is real this time.

"I believe it's going to happen," said resident David Hubble, who has voiced the community's concerns for years. "It's an important step, a necessary step, a step that should have been taken almost six years ago.

A problem with packaging of goods arises when the packaging creates an environment which negatively affects the packaged content. One example is the packaging of fine art or other materials which decay or go bad when moisture or a humidcondition is trapped. Another example is the negative effect on packaged food due to steam vapor in a container such as a paper box or bag. The steam that emanates from a hot food such as pizza, french fries, etc. forms condensation that settles withinthe box or bag, making the pizza or french fries soggy or spongelike. In the case of packaging used for temporarily storing and transporting a hot pizza pie, the packaging is typically a box constructed of either corrugated boxboard, or containerboard. Corrugated boxboard is made by gluing an accordion-like sheet of paper (corrugated medium) in between two sheets of linerboard. Containerboard, or what is also called `clay kraft back` is a paperboard that does not have any corrugated layer. Containerboard is commonly used for forming boxes such as a shoe box. The condensation that settles on the inside bottom surface of the pizza box is absorbed by the pizza dough by the time the pizza is transported to a place where it can be consumed. Similarly, the Kraft Paper commonly used as grocery bags fortemporarily housing other hot food such as french fries, fried chicken, etc. also cannot absorb the vapor from the hot food. The trapped vapor renders the french fries soggy. According to an embodiment of the present invention, a container for housing food is provided, comprising paper having carbon additives for absorbing moisture emanating from the food, wherein the carbon additives include one of charcoal,activated charcoal and activated carbon, wherein the paper is one of a containerboard, a linerboard, and a corrugated medium. According to an aspect of the present invention, the container, preferably a corrugated boxboard, includes a plurality of sheets or linerboards, and the carbon additives are embedded in at least one of the plurality of sheets or linerboards,wherein the sheets of paper are made from a mixture of pulp, water, and the carbon additives. A method is also provided for absorbing moisture from food within a container comprising; embedding carbon additives within paper, and forming the container using the paper. Preferably, the carbon additives include charcoal, activated charcoaland activated carbon. The paper is one of a linerboard, a containerboard, and a corrugated medium. The paper includes a plurality of sheets, each sheet formed from a plurality of layers, and the carbon additives are embedded in at least one of theplurality of sheets. The sheets of paper are made from a mixture of pulp, water, and the carbon additives, wherein one, two or three of the plurality of sheets are embedded with the carbon additives. A process for manufacturing a container for storing food is also provided, comprising; forming layers of paper with embedded carbon additives by mixing pulp, water, and the carbon additives; and forming a boxboard with a plurality of sheets oflinerboards of the paper to house the food, wherein the step of forming a box includes using a plurality of layers of paper forming sheets or linerboards, including at least an inner linerboard and an outer linerboard. The process further includingadding perforations to the inner linerboard and corrugating one of the plurality of sheets of paper. Other uses and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings which disclose several embodiments of the present invention. It should beunderstood, however, that the drawings are designed for the purpose of illustration only and not as an exhaustive list of its possible uses. The invention is directed to packaging product for housing goods. The packaging product is preferably made of paperboard, linerboard, or containerboard having charcoal, activated charcoal, or activated carbon as an additive for absorbingmoisture, vapor, or condensation (hereinafter referred to as "Coalboard"). Charcoal, activated charcoal, carbon, or substances mostly comprised of carbon are used as additives because of their superior absorbent characteristics, partly due to theirextremely vast surface area. The charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon is mixed with the wood fiber (more commonly known as pulp) in the blend chest. The refined pulp and water with the charcoal,activated charcoal, activated carbon, or substances mostly comprised of carbon added would then be sent on to the papermaking machine. In one embodiment, the linerboard with the embedded charcoal is disposed within a packaging container which isperforated on the interior side to enable steam vapor or humidity to enter into the corrugated medium. In another embodiment, a boxboard is made of containerboard with embedded charcoal, activated charcoal or substances mostly comprised of carbon. Withthis packaging and method according to the present invention, the contents of the package can be protected against humidity, moisture, and steam. FIG. 1 shows a pizza box made of Coalboard according to the present invention. The steam vapor that is emitted from the pizza would be drawn through the perforations and be absorbed by the charcoal. It is readily apparent that pizza is onlyone example of packaged food that would benefit from the vapor absorbing qualities of CoalBoard. Although this is one embodiment of the present invention, it is not the exclusive embodiment. Referring to FIGS. 1 to 3 and according to a first embodiment of the present invention, all three sheets of the boxboard 1, which comprises exterior linerboard 3, interior linerboard 5, and corrugated medium 4 are embedded with charcoal,activated charcoal, activated carbon, or substances mostly comprised of carbon. The interior linerboard 5 that faces the food product includes perforations 2 to enable the steam vapor generated from the hot food to enter into the corrugated medium 4. According to a second embodiment of the invention, two sheets of the boxboard 1, preferably interior linerboard 5, and corrugated medium 4 are embedded with charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbonas an additive. The interior linerboard 5 facing the food product is preferably perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4. According to a third embodiment of the invention, the exterior linerboard 3, and corrugated medium 4 are embedded with charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon as an embedded additive. Theinterior linerboard 5 facing the food product would be perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4. According to a fourth embodiment of the invention, one sheet of the boxboard 1, preferably the interior linerboard 5 is embedded with charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive. Theinterior linerboard 5 facing the food product would be perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4. According to a fifth embodiment of the invention, the exterior linerboard 3 is the only sheet having charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive. The interior linerboard 5 facing thefood product would be perforated 2 to enable the steam vapor to enter into the corrugation 4. According to a sixth embodiment of the invention, the corrugated medium 4 is the sheet having charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive. The interior linerboard 5 facing the foodproduct would be perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4. As an alternative to mixing the additive in the pulp formulation process, there are a number of processes that can be used to introduce charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon into paper. Oneexemplary process is by blade coating, which is a method of coating paper and paperboard using a flexible blade to control the amount of coating applied to the paper. Blade-coating can take place either on a papermaking machine or on an off-machinecoater. The paper may be coated on one side (C1S) or both sides (C2S), or between layers of paper as described in the above embodiments. Off-machine coating refers to coating paper after it comes off the papermaking machine rather than while it isstill on the machine. Preferably, an off-machine coater is used to add one or more layer of coating of the carbon material to the paper. Other known processes such as bath coating or surface sizing coating may also be used to mix or coat the carbonmaterial onto the paper. We did four side-by-side tests with identical pizza pies under the identical conditions. We lined the perimeter of one of the boxes with pulverized charcoal, and left the other box as it would normally be used. After nine minutes cooking at500 degrees (industry standard), we placed both pies in their respective boxes and let them settle for 5, 7, 10, and 15 minutes. The first three tests were conducted as stated above, the third test we perforated an additional box top and stapled it tothe actual top with charcoal sandwiched in between. In each case, the pizza that was in the box with the charcoal was noticeably more crispy. The longer the period of time that we let the pies settle, the more pronounced the effect. Having thus described the invention with the details and particularity required by the patent laws, it is noted that modifications and variation can be made by persons skilled in the art in light of the above teachings. It is therefore to beunderstood that changes may be made in the particular embodiments of the invention disclosed which are within the scope and spirit of the invention as defined by the appended claims.
