Definitions

  • hemp paper to manufacture paper sleeves and other devices made from hemp for holding cups.
  • Hemp is a source of fiber that comes from the plant species Cannabis sativa. Hemp can be produced much faster than trees. Hemp stalks grow in four months, whereas trees can take twenty to eighty years. One acre of hemp can yield 1,300 pounds of fiber and produce as much paper as four to ten acres of trees over a twenty year cycle. Unlike trees, hemp plants can be grown without using any pesticides or herbicides. The wider use of hemp plants can reduce deforestation.
  • Hemp plant stalks have two parts.
  • the bast fibers, or outer part of the stalk have a grassy texture and typically contain almost 80% cellulose.
  • the hurd, or inner part of the stalk has a woody core made up of cellulose-laden bundles of short fiber.
  • the process of separating the bast fiber from the hurd fiber is called decortication.
  • dew retting or water retting is typically done first. Retting uses bacteria and moisture to dissolve away the gummy substances that surround bast fiber bundles.
  • Hemp paper is a plant based, non-toxic, sustainable alternative to conventional paper made from trees. Hemp paper is primarily made from the bast fibers of hemp plants. Hemp paper has a low lignin and high cellulose content. Hemp paper does not age or discolor with time. The quality of hemp paper is better than that of paper made from the wood pulp of trees. Hemp paper is thin, and lightweight, with a high degree of stiffness. Hemp paper is tough, brittle and rough. Wood pulp paper is softer and thicker than hemp paper. Hemp paper is more difficult to make and is stronger than wood pulp paper. Hemp paper can be recycled up to eight times, compared to just three times for paper made from wood pulp.
  • U.S. Pat. No. 5,080,702 relates to a disposable two-ply filter for a vacuum cleaner bag, wherein the outer ply may be wood paper, hemp paper or any other filter paper, cloth or fabric well known in the art.
  • U.S. Pat. No. 5,700,599 relates to a high absorption rate battery separator of a non-woven cellulosic substrate coated on at least one surface with a cellulosic film and a process for making such separator by contacting a nonwoven cellulosic textile substrate with a cellulose or cellulose derivative solution on at least one side of the substrate.

Description

    RELATED APPLICATIONS
  • This application is a continuation-in-part of U.S. application Ser. No.. 17/868,669 filed Jul. 19, 2022 which is a continuation-in-part of U.S. application Ser. No. 17/855,536 filed Jun. 30, 2022, which claims benefit and priority to U.S. provisional application Ser. No. 63/224,320 filed Jul. 21, 2021
    • FIELD OF THE INVENTION
  • The use of hemp paper to manufacture paper sleeves and other devices made from hemp for holding cups.
    • BACKGROUND OF THE INVENTION
  • In the food service industry, consumers appreciate disposables that can be stored compactly and readied for use quickly. Food establishments serve hot and cold beverages and soups. It is desirable to use an insulating holder sleeve or collar which can slip over the outside of a beverage cup or soup container when the cup or container contains hot liquids. In addition, it is desirable to use a tray to hold or carry multiple beverage cups or containers.
  • Hemp is a source of fiber that comes from the plant species Cannabis sativa. Hemp can be produced much faster than trees. Hemp stalks grow in four months, whereas trees can take twenty to eighty years. One acre of hemp can yield 1,300 pounds of fiber and produce as much paper as four to ten acres of trees over a twenty year cycle. Unlike trees, hemp plants can be grown without using any pesticides or herbicides. The wider use of hemp plants can reduce deforestation.
  • The hemp-growing industry is regulated throughout the United States. Recent regulations have sought to encourage this nascent industry as biodegradable hemp raw materials can be turned into biodegradable hemp-based products. Biodegradable hemp products break down in approximately 90 days versus the dozens of years it takes petroleum-based plastics to break down into microplastics that frequently end up in the ocean.
  • Hemp plant stalks have two parts. The bast fibers, or outer part of the stalk have a grassy texture and typically contain almost 80% cellulose. The hurd, or inner part of the stalk, has a woody core made up of cellulose-laden bundles of short fiber. The process of separating the bast fiber from the hurd fiber is called decortication. To facilitate decortication, dew retting or water retting is typically done first. Retting uses bacteria and moisture to dissolve away the gummy substances that surround bast fiber bundles.
  • Hemp paper is a plant based, non-toxic, sustainable alternative to conventional paper made from trees. Hemp paper is primarily made from the bast fibers of hemp plants. Hemp paper has a low lignin and high cellulose content. Hemp paper does not age or discolor with time. The quality of hemp paper is better than that of paper made from the wood pulp of trees. Hemp paper is thin, and lightweight, with a high degree of stiffness. Hemp paper is tough, brittle and rough. Wood pulp paper is softer and thicker than hemp paper. Hemp paper is more difficult to make and is stronger than wood pulp paper. Hemp paper can be recycled up to eight times, compared to just three times for paper made from wood pulp.
  • U.S. Pat. No. 5,080,702 relates to a disposable two-ply filter for a vacuum cleaner bag, wherein the outer ply may be wood paper, hemp paper or any other filter paper, cloth or fabric well known in the art.
  • U.S. Pat. No. 5,700,599 relates to a high absorption rate battery separator of a non-woven cellulosic substrate coated on at least one surface with a cellulosic film and a process for making such separator by contacting a nonwoven cellulosic textile substrate with a cellulose or cellulose derivative solution on at least one side of the substrate. Preferred nonwovens are paper webs such as hemp paper bonded with hydrogen bonds, cellulose or food grade binders.
  • U.S. Pat. No. 7,537,514 relates to a double casing with netting for food products, wherein the material of the tube comprises a combination of materials selected from the group consisting of edible collagen of bovine or porcine origin, inedible collagen, regenerated collagen, regenerated or fibrous collagen, plastic material, hemp paper, any type of paper, and a polysaccharide.
  • U.S. Pat. No. 7,666,484 relates to a ready to use food packaging film, wherein in one embodiment the film is made out of hemp paper.
  • U.S. Pat. No. 5,744,251 relates to a cellulosic composition and article. Fibrous casing made in the casing industry is produced by coating regenerated cellulose onto a sheet or tube of hemp paper.
  • US patent publication 20190280135 relates to a room temperature printing method for producing a PV layer sequence. The process is characterized in that the carrier used for the PV layer sequence comprises continuous, flat sheets of material, preferably sheets of film and/or sheets of paper, more preferably sheets of hemp paper. Hemp offers the advantage that it can be manufactured in a sulfate-free manner; provided with additional moisture inhibitor and/or biocide, such as hemp paper can advantageously withstand high temperatures without yellowing or significant mechanical degradation or any decline in its properties.
  • U.S. Pat. No. 5,425,497 relates to a flat, elongated sheet or band in arcuate form with notched ends being made of paperboard material embossed with nubs and semi-spherically shaped depressions to provide an insulating layer as well as gripping of the sides of the cup. For holding a cup, the flat band is rolled in a circle and then its notched ends must be interlocked to each other to form a sleeve in which a cup can be inserted. The need to interlock the notched ends on-site risks possible breakage or improper assembly.
