Enhanced bonding and sealing between two fibrous materials

A method for bonding two biodegradable materials comprising:

• configuring a carrier, said carrier comprising a composite material with fibrillated cellulose having independently derived plant fibers, said composite material being generally free from toxic chemical additives, said chemical additives adapted for improving dry tensile strength, enhanced oil barrier, gas and/or liquid impermeability, a dry tensile modulus, or a dry tensile index;
• wherein the composite material comprises properties of:
• an oxygen transmission rate of about 8000 cm3 m−2 24 h−1 or less,
• a water vapor transmission rate of 3000 g m−2 24 h−1 or less,
• a dry tensile strength of about 30 MPa or higher,
• a dry tensile modulus of about 4 GPa or higher, and
• a dry tensile index of about 45 Nm g−1 or higher;
• wherein the carrier comprises walls connected to a base at one end for defining a volume, said carrier further comprising a lip extending from the other end of the walls;
• configuring a cover having a portion thereof to engage the lip of the carrier at an engagement zone;
• and
• infusing a filler at the engagement zone to enclose the volume defined by the carrier, wherein the filler comprises one of the following:
• plant-based starch glues;
• chemically modified starch glue;
• water-based glues that comprises polyvinyl acetates (PVA), vinyl acetate ethylenes (VAE) and vinyl acetate acrylates (VAA);
• dextrin glues;
• ethylene-vinyl acetate (EVA) hot melt glue, metallocene hot melt glue, fugitive hot melt glue and polyurethane reactive (PUR) hot melt glue, polyvinyl alcohol (PVOH) or partially hydrolysed polyvinyl acetate (PVA) hot melt glue;
• PLA;
• PHA;
• epoxy resin;
• gelatin, water, magnesium sulfate, corn sugar, glycerin and protein;
• polyacrylated epoxidized soybean oil;
• silicone sealant;
• natural wax;
• synthetic wax;
• phenol formaldehyde;
• urea formaldehyde;
• cyanoacrylate;
• polysaccharide (agarose);
• or metallocene.
