Abstract
Wadding, insulation and packaging for food and other products is made of pure homogeneous polyester terephthalate (PET) that satisfies the resin recycling identification code number “1”. For purposes of protecting an inner wadding or other insulation, one or more film strips or film coatings may be applied by the artful use of amorphous (non-crystalized) PET or other types or configurations of PET, such that a filmstrip and/or wadding melts at a lower temperature and can act as a thermal bond adhesive. The film strips or film coatings may be made of homogeneous polyester terephthalate (PET) made of pure PET.
Claims
1. A laminate system of insulation material made of pure polyethylene terephthalate (“PET”), the laminate system comprising: a first film made of pure PET; a wadding made of pure PET; wherein the wadding is fastened to the first film.
2. The laminate system of claim 1 wherein the wadding is fastened to the first film by use of heat.
3. The laminate system of claim 1 wherein the first film is made of pure PET only.
4. The laminate system of claim 1 wherein the wadding is made of pure PET only.
5. The laminate system of claim 2 wherein the heat used to fasten the first film to the wadding is in the range of 200 to 400 degrees.
6. The laminate system of claim 1 wherein the first film comprises a side with amorphous PET facing the wadding.
7. The laminate system of claim 1 further comprising a second film of pure PET fastened to the wadding.
8. The laminate system of claim 6 wherein the wadding is fastened to the first film by adhering to (1) the side of the first film comprising the amorphous PET.
9. The laminate system of claim 8, wherein the amorphous PET from the side of the first film is thermally bonded to the wadding without compromising structural integrity of the wadding.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0072] The following detailed description is directed to certain specific embodiments of the invention. However, the invention can be embodied in a multitude of different ways as defined and covered by the claims and their equivalents. In this description, reference is made to the drawings wherein like parts are designated with like numerals throughout.
[0073] Unless otherwise noted in this specification or in the claims, all of the terms used in the specification and the claims will have the meanings normally ascribed to these terms by workers in the art.
[0074] Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in a sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number, respectively. Additionally, the words “herein,” “above,” “below,” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application.
[0075] The above detailed description of embodiments of the invention is not intended to be exhaustive or to limit the invention to the precise form disclosed above. While specific embodiments of, and examples for, the invention are described above for illustrative purposes, various equivalent modifications are possible within the scope of the invention, as those skilled in the relevant art will recognize. For example, while steps are presented in a given order, alternative embodiments may perform routines having steps in a different order. The teachings of the invention provided herein can be applied to other systems, not only the systems described herein. The various embodiments described herein can be combined to provide further embodiments. These and other changes can be made to the invention in light of the detailed description.
[0076] Any and all the above references and U.S. patents and applications are incorporated herein by reference. Aspects of the invention can be modified, if necessary, to employ the systems, functions and concepts of the various patents and applications described above to provide yet further embodiments of the invention.

[0082] Materials used in fabricating disclosed insulation compositions include, recycled cardboard, resulting in an organic craft color, starch, green fiber. Insulation may be repulpable, recyclable, reusable and configurable in many thicknesses with a preferred thickness in the range of a quarter of an inch to one and a half inches.
[0083] Insulation may comport to preferred densities of one to two pounds per cubic foot.
[0084]
[0085]
[0086]
[0087] Embedded seeds may have certain size restrictions in comparison to the machinery making the insulation. In one disclosed embodiment, seeds are disposed at or near the surface of insulation to better preserve the insulation making equipment. Disclosed embodiments may be 100 percent curb side recyclable.

[0096] With respect to the void that helps to define the box wing, the slot may be half of the width of the box. Since a 5 inch slot will equal a 10 inch wing, the approximate size of the box. If cut shorter, a gusset may be formed that will allow the sleeve to hold a small amount of fluid. Such fluid would remain in the box so long as the box is approximately level. The thickness of the insulation may be made of any thickness. Other proportions are subject to change to comport with the needs of the shipper and/or container.

[0098] This method of using amorphous (non-crystalized) PET or any other types or configurations of PET to thermally bond a film strip to the wadding overcomes shortfalls in the prior art in that the disclosed method of attachment keeps the overall structure within the chemical boundaries of resin recycling identification code number “1” as no impurities are introduced. The disclosed use of amorphous (non-crystalized) PET upon the inner sides of the film strips allows for a relatively lower melting temperature to thermally bond the strips to the rigid wadding so as to not compromise the structural integrity of the rigid wadding. The chemical boundaries defining a recycling identification code number “1” may include the use of pure PET only.
[0099] The resulting disclosed structure may be manufactured in continuous sheets wherein low heat is applied to thermally bond the film strips to the upper and lower sides of the rigid wadding. The disclosed use and attachment of film to the rigid wadding overcomes shortfalls in the art by providing a protective film upon the rigid wadding to prevent fraying and other frictional damage to the rigid wadding. The disclosed application of film to the rigid wadding overcomes shortfalls in the art by providing smooth outward surfaces such that the insulation sheets may be slideably stacked and unstacked without snags or undue friction.
[0100] A rigid wadding system or other insulation system may comprise thermoplastic with binder fiber; powder binders and PLA. A first or second film attached to a wadding may be thermally attached by use of heat, the heat in the range of 200 to 400 degrees.
[0101] Disclosed embodiments may use starch adhesives, craft paper, bio resin, sugar cane or corn starch.
[0102] Disclosed embodiments include the use of corrugated cardboard sometimes covered in craft paper with the pulp of said components comprising repulpable biodegradable and sometimes embedded with seeds. Disclosed embodiments include a balancing of pH so as to optimize the growth of seeds imbedded into the paper or other shipping materials. Such pH may be in the range of 3 to 8 pH.
[0103] The definition of “pure PET” may include the presence of de minimus substances inadvertently introduced during a manufacturing process.
