a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the closure is opened and the tube is collapsed, flowable material inside the tube is urged out of the nozzle; and the bioplastic material includes a bio resin selected from the group consisting of PEF, PBF, PTF, GPE, GPET, PLA, PDLA, PLLA, PHA, and PHBH. A method may include forming a tube and filling the tube with flowable material from the distal end. ## Claims ### Claim 1 A device for dispensing a flowable material, comprising: a collapsible tube comprising a wall comprising a first layer of bioplastic material, a second layer of bioplastic material and a thin layer of metal foil sandwiched between and adjacent to a first layer of adhesive and a second layer of adhesive, the first layer of adhesive positioned adjacent the first layer of bioplastic material and the second layer of adhesive positioned adjacent to the second layer of bioplastic material: a distal end of the tube that is sealed; and a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the tube is configured to collapse to urge the flowable material inside the tube out of the nozzle; wherein the first layer of bioplastic material and the second layer of bioplastic material comprise a bio resin selected from the group consisting of: poly (ethylene 2, 5-furan dicarboxylate) (PEF), poly (butylene 2, 5-furan dicarboxylate) (PBF), and poly (tri methylene furan dicarboxylate) (PTF); wherein the first layer of bioplastic material and second layer of bioplastic material, each comprising the bio resin, further comprise one or more flex agents in a ratio of 5 to 15% total flex agent to total weight, wherein the one or more flex agents comprises acetyl tributyl citrate (ATBC), and wherein the thin layer of metal foil is aluminum foil. ### Claim 2 (depends on 1) The device of claim 1, further comprising a metal foil pouch within the tube that retains the flowable material. ### Claim 3 (depends on 1) The device of claim 1, wherein the bio resin is selected from the group consisting of: poly (butylene 2, -5-furan dicarboxylate) (PBF), and poly (tri methylene furan dicarboxylate) (PTF). ### Claim 4 A method for making a collapsible dispensing tube, comprising: providing a tube having a distal end and a proximal end, the tube comprising a wall comprising a first layer of bioplastic material, a second layer of bioplastic material and a thin layer of aluminum foil sandwiched between and adjacent to a first layer of adhesive and a second layer of adhesive, the first layer of adhesive positioned adjacent the first layer of bioplastic material and the second layer of adhesive positioned adjacent to the second layer bioplastic material;

and wherein the first layer of bioplastic material and the second layer of bioplastic material each comprising the bio resin, further comprise one or more flex agents in a ratio of 5 to 15% total flex agent to total weight, wherein the one or more flex agents comprises acetyl tributyl citrate (ATBC). ### Claim 5 (depends on 4) The method of claim 4, further comprising: sealing a side of each of the first layer of bioplastic material and the second layer of bioplastic material together. ### Claim 6 (depends on 4) The method of claim 4, further comprising: injection molding, blow molding, or extruding the bio resin to provide the first layer of bioplastic material and the second layer of bioplastic material; and inserting a foil pouch into the tube. ### Claim 7 (depends on 4) The method of claim 4, wherein the bio resin is selected from the group consisting of: poly (butylene 2, 5-furan dicarboxylate) (PBF), and poly (tri methylene furan dicarboxylate) (PTF). ### Claim 8 A device for dispensing a flowable material, comprising: a collapsible tube comprising a multilayer wall, the multilayer wall comprising: a first layer of bioplastic material, a second layer of bioplastic material, each of the first layer of bioplastic material and the second layer of bioplastic material comprising a bio resin, the bio resin selected from the group consisting of: poly (ethylene 2, 5-furan dicarboxylate) (PEF), poly (butylene 2, 5-furan dicarboxylate) (PBF), and poly (tri methylene furan dicarboxylate) (PTF); and a barrier layer positioned between and adjacent to a first layer of adhesive and a second layer of adhesive, the first layer of adhesive positioned adjacent to the first layer of bioplastic material and the second layer of adhesive positioned adjacent to the second layer of bioplastic material; a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; and a nozzle coupled to the opening, wherein the first layer of bioplastic material further includes, in addition to the bio resin, one or more flex agents comprising acetyl tributyl citrate (ATBC), and wherein the barrier layer is a thin layer of aluminum foil. ### Claim 9 (depends on 8) The device of claim 8, wherein the multilayer wall is a bio resin aluminum barrier laminate (BABL). ### Claim 10 (depends on 8) The device of claim 8, wherein the bio resin is injection molded, blow molded, or extruded to provide the first layer of bioplastic material and the second layer of bioplastic material. ### Claim 11 (depends on 8) The device of claim 8, wherein the one or more flex agents are in a ratio of 5 to 15% total flex agent to total weight. ### Claim 12 (depends on 8) The device of claim 8, wherein the bio resin is selected from the group consisting of: poly (butylene 2, 5-furan dicarboxylate) (PBF), and poly (tri methylene furan dicarboxylate) (PTF).
