Abstract
Fast food wrappers, sandwich wrappers and gum wrappers which comprise PLA. P/73-38
Claims37
A gum wrapper comprising;
- paper, PLA resin and foil;
- said PLA resin is placed on an outside package of said gum wrapper for a printed film substrate to be placed on said paper/PLA/foil lamination.
A wrapper for fast food, sandwich and burgers comprising;
- two sheets of paper having a weight in the range of about 10 to 30 pounds laminated with PLA resin, forming a paper/PLA/paper structure.
A wrapper for fast food, sandwich and burgers comprising:
- a paper substrate having a weight in the range of about 10 to 30 pounds coated with a PLA resin on one side.
A gum wrapper comprising;
- a paper substrate having a weight in the range of about 8 to 35 pounds laminated to an extruded foil using PLA to create a single stick gum wrapper (paper/PLA/foil lamination).
An outside wrapper for individually wrapped gum sticks comprising;
- a paper substrate having a weight in the range of about 8 to 30 pounds laminated to an extruded foil using PLA to create a an outside package for individually wrapped gum sticks whereby customers glue a printed film substrate to said paper/PLA/foil lamination.
A composite wrap material comprising;
- two layers or sheets of cellulosic material;
- and
- a layer of PLA resin interposed between said two cellulosic layers.
A method for making a composite wrap material comprising:
- laminating a three-layer structure comprising two layers of paper;
- interposing a PLA layer or film layer between said paper layers using a nip roller apparatus or other suitable laminating device;
- bonding said layers together.
A composite wrap material comprising:
- one layer or sheet of cellulosic material;
- and
- a layer of PLA resin material that is integrally bonded to said cellulosic material by means of an adhesive.
A composite wrap material comprising:
- a layer of paper or cellulosic material;
- and
- two or more layers of different resins simultaneously applied to one side of said paper.
- one resin having low moisture transmission rates and/or high strength characteristics and;
- other resin having heat seal or glueable characteristics similar to polyethylene coated wraps.
A process for making a composite material comprising:
- providing a first sheet of cellulosic material and a second coextruded layer comprising two layers of polymer and/or PLA resin materials;
- applying said coextrusion layers to a surface of said first sheet;
- conveying said first sheet and said second coextrusion layers into a laminating apparatus where said layers are bonded;
- forming an integral composite material.
A wrap for fast food items, sandwiches, and/or burgers comprising:
- first and second cellulosic layers comprising a printed or non-printed paper substrate with a basis weight of 10 to 30 pounds per 3,000 sq. ft;
- and
- a layer of PLA resin interposed between said cellulosic layers.
A wrap for fast food items, sandwiches, and/or burgers comprising;
- a first cellulosic layer comprising a printed or non-printed paper substrate with a basis weight of 10 to 30 pounds per 3,000 sq, ft;
- a layer of PLA resin coated on said cellulosic layer.
A wrap for wrapping individual sticks of chewing gum comprising:
- a first cellulosic layer comprising a paper substrate with a basis weight of approximately 8 to 30 pounds per 3,000 sq. ft;
- said paper layer laminated to a layer of extruded foil using PLA resin as an interposing layer.
An outside wrapper for packaging a specified quantity of individually wrapped sticks of chewing gum comprising:
- a first cellulosic layer comprising a paper substrate with a basis weight of 10 to 35 pounds per 3,000 sq. ft.;
- said paper layer adhered to a printed solid plastic film substrate using PLA resin interposed therein between.
