Thermoplastic structures for the storing and transporting of organoleptic sensitive products
View Patent ↗The present invention relates to thermoplastic structures wherein the inner sealant layer of said structure comprises a polyethylene having a density from about 0.88 to about 0.96 and wherein the polyethylene is processed at a temperature ranging from about 150° F. to about 500° F. in order to prevent the release of extractable materials. The thermoplastic structures can be used independently to form a flexible packaging film or can be affixed to a second film structure or substrate to form a flexible packaging film. The flexible packaging films can be used for forming containers for the storing and transporting of organoleptic sensitive products.
1. A thermoplastic structure for use in the storing and transporting of organoleptic sensitive products comprising:
an outer layer comprising linear low density polyethylene;
a middle layer comprising linear low density polyethylene;
a tie layer comprising linear low density polyethylene adhesive;
a middle layer comprising poly(hexamethylene adipamide);
a middle layer comprising ethylene vinyl alcohol copolymer;
a tie layer comprising linear low density polyethylene adhesive; and
an inner sealant layer comprising a metallocene catalyzed polyethylene having a density of about 0.90 wherein the polyethylene is extruded at a temperature of about 350° F.; and wherein said outer layer is adhesive laminated to a film structure comprising poly(ethylene terephthalate).
2. A container for storing and transporting organoleptic sensitive products wherein the container is made from the structure of claim 1 .
3. The container for storing and transporting organoleptic sensitive products according to claim 2 wherein the container is a pouch.
4. A thermoplastic structure for use in the storing and transporting of organoleptic sensitive products comprising:
an outer layer comprising a metallocene catalyzed polyethylene having a density of about 0.90;
a middle layer comprising linear low density polyethylene; and
an inner sealant layer comprising a metallocene catalyzed polyethylene having a density of about 0.90 wherein the polyethylene is extruded at a temperature of about 350° F.; and wherein said outer layer is adhesive laminated to a film structure comprising poly(ethylene terephthalate).
5. A container for storing and transporting organoleptic sensitive products wherein the container is made from the structure of claim 4 .
6. The container for storing and transporting organoleptic sensitive products according to claim 5 wherein the container is a pouch.
7. A thermoplastic structure for use in the storing and transporting of organoleptic sensitive products comprising:
an outer layer comprising a metallocene catalyzed polyethylene having a density of 0.90;
a middle layer comprising orientated polypropylene; and
an inner sealant layer comprising a metallocene catalyzed polyethylene having a density of about 0.90 wherein the polyethylene is extruded at a temperature of about 350° F.; and wherein said outer layer is adhesive laminated to a film structure comprising a blend of poly(ethylene terephthalate) and PVdC.
8. A container for storing and transporting organoleptic sensitive products wherein the container is made from the structure of claim 7 .
9. The container for storing and transporting organoleptic sensitive products according to claim 8 wherein the container is a pouch.
