Definitions
- This invention relates to a new class of materials to be used as substitutes for polyethylene and poly (ethylene terephthalate) , commonly known as PET.
- Polyethylene and PET have many uses.
- waterproof or water-resistant paper or paperboard can be made with polyethylene and PET coatings.
- Many products can be produced from such waterproof or water-resistant paper or paperboard, for example: dishes, trays or other containers. These products can be used, for example, in prepackaging foodstuffs that are to be reheated or cooked in a microwave oven.
- waterproof paper or paperboard, coated or laminated with a multi-thermoplastic material, such as high-density polyethylene, or coated with an aqueous latex solvent solution of a polymer include, among the commercially important thermoplastic products PET.
- the resulting paper or paperboard is useful for boxes, bags, drums, and case liners among other industrial products and packaging materials. Excellent barrier properties to water, oil, water vapor, oxygen, and some other gases make paper and paperboard coated with these resins especially- valuable and flexible for use as packaging materials and boxes .
- PET is not recyclable when contained on paper and/or paperboard products (See, the aforementioned Kirk- Othmer, Volume 3, Pages 497 - 502) . PET is not recyclable when in a mixture with paper and/or paperboard products. PET is not recyclable when layered with paper and/or paperboard products. Thus, a need exists to identify a suitable alternative for polyethylene and PET. Otherwise, timber resources will be further despoiled to create new or replacement products; scarce landfill space will be filled; and incineration of used paper products will cause further pollution.
- the present invention provides a substitute for paper or paperboard products coated or laminated with multi-thermoplastic materials, such as polyethylene, or coated with an aqueous latex solvent solution of such materials, such as PET.
- multi-thermoplastic materials such as polyethylene
- an aqueous latex solvent solution of such materials such as PET.
- the polyethylene and/or PET replacement coating is also useful for all types of paper, bag stock, ream wrap, roll wrap, corrugated, folding board, solid fiber, paper- based microwavable or conventional oven, food trays.
- waterproof or water- resistant paper and paperboard products are formed by substituting an acrylic containing material for the polyethylene and/or PET previously utilized.
- Such acrylics or polyacrylates can be used to prepare coatings and solution polymers and polymerization processes providing high yields of polymers in a form suitable for a variety of applications.
- the polymer products can be made to vary widely in physical properties through controlled variation in the ratios of monomers, employed in their preparation, cross- linking, and control of molecular weight. They share common qualities of high resistance to chemical environmental attack, excellent clarity, and attractive strength properties .
- acrylic acid itself methyl, ethyl, butyl, isobutyl, and 2 -ethyl acrylates are commercially manufactured on a large scale and are available at better than 98 - 99% purity.
- Suitable cross- linking agents for the acrylates include compounds of zinc, such as zinc oxide solution.
- Zinc oxide solution is a fine suspension of zinc oxide particles usually in an aqueous vehicle.
- Many other compounds can be used as cross- linking agents.
- at least one crosslinking agent is selected from the group consisting of zinc oxide, ammonium oxide, calcium oxide, calcium stearate, magnesium stearate, aluminum oxide, isostearate, magnesium oxide, stannous oxide, tungsten oxide, sodium tungstate, sodium tungstate dihydrate, titanium oxide, aluminum stearate, zinc octoate, zinc salts of fatty acids, zirconium oxide, calcium isosterate, calcium salts of fatty acids, magnesium salts of fatty acids, and aluminum salts of fatty acids.
- the cross- linking agent includes a salt (as described herein) plus a butyric acid and 5-carbon acids, such as isobolic 2- ⁇ nethyl buteric and N-valeric acid.
- the fatty acids are fatty acids of animal and/or vegetable fats and oils and would be exempt from kosher compliance, since the potential use of animal oils in the origin of the animal in question may be unspecified. In such cases, the inorganic substances would be preferred. It is considered within the scope of this invention to incorporate more than one substance to form the cross -linking agent.
- cross -linking agent includes the above-described compositions as well as heat, radiation or any other method for initiation a cross-linking reaction in acrylic materials .
- cross- linking agents include ZINC OXIDE SOLUTION NO. 1, available from Johnson Wax Specialty Chemicals of Racine, Wisconsin.
- the cross-linking agent is used in amounts sufficient to crosslink the acrylic material.
- the acrylic materials of the present invention are preferably coated onto the paper or paperboard material in any of a variety of ways.
- rolls of paper and kraft liners are unwound from a parent reel or a slit or slash winder into rolls of smaller size or feed into sheeters, such as cut-size sheeters.
- Two methods of coating boxes or other paper products are preferably utilized.
- the first method is identified as a curtain coating process.
- a completed board is passed through a curtain of emulsion of an acrylic as in the present invention in a procedure commonly known in the art of paper making as "curtain coating.”
- the face side of the board and the opposite side are coated with the emulsion.
- the second coating process is "cascading."
- the cascading procedure is different from the curtain coating procedure in that a regularly corrugated box of any shape or size can be placed on one end, such that the corrugated flutes are vertical, to allow the emulsion to permeate the entire structure with the acrylic emulsion cascading around and through the container in a flat position that is easy to stack for shipping.
- Other methods of coating include coating the paper or paperboard during the paper making process.
- the paperboard during the paper making process or a paper or kraft grade of liner may be sprayed with an emulsion after the press section, but before the drying section of a typical paper making process or may be dipped into an emulsion such that in a typical size press or applied before or after the calendar section.
- coating means “coating” or “impregnation” unless otherwise indicated.
- the coatings of the present invention exhibit excellent resistance to penetration by oil, grease and other materials, but they also exhibit excellent release properties when utilized as trays or pans containing a flour or flour substitute foodstuff, eggs, pastas, and sauces and vegetables and/or meets with or without gravies or sauces.
- the present invention has a wide range of packaging of foodstuffs that may require heating, cooking, reheating, microwave and/or other ovens.
- FIG. 1 shows a photograph, illustrating various releases of yellow cake and traditional fudge brownies as baked in baking trays;
- FIG. 2 shows a photograph of Quiche baked in a tray having a 56 Ib pine liner
- FIG. 3 shows a photograph of trays made according to the present invention after release of the Quiche baked therein.
- Sample 4, 5 and 6 have better release than samples 1, 2, and 3. Sample 4 had the best release, especially if well-baked. A summary of release properties can be found in FIG. 1.
- a second battery of tests was conducted similar to the first round including a comparative example to PET.
- the coatings are as follows:
- FIG. 2 shows a photographic illustration of the sample 1, as compared to FIG. 3, which is a photographic comparison of the trays made according to the present invention after release of the product.
