Advanced Cellulose-based Materials for Sustainable Packaging

Eco-friendly internal packaging material made from a biocomposite of mycelium, pine needles, wheat straw, and wood powder. The composite is reinforced with pine needles and grown using Pleurotus ostreatus mycelium. It provides cushioning and protection for fragile items like electronics while being fully biodegradable. The composite is made by inoculating the substrate with mycelium, sterilizing, growing, and heat treating to cure.

A composite support element for packaging heavy products like white goods that provides durability during transportation and stacking. The support element has a base made from cellulosic materials like urea formaldehyde, melamine formaldehyde, or melamine urea formaldehyde glues. This base is covered by layers of paper. An additional layer of metal can be added between the base and paper layers or outside them to further reinforce the support element.

Method for manufacturing a rigid, eco-friendly paper string for packaging that can replace plastic straps. The paper string is made by applying an adhesive to a paper base, joining two side bands, folding the paper multiple times, coating it, and winding it. This provides a paper string that is stronger, doesn't break easily, and can be reused or recycled after packaging. The coated paper string is wound around a roller to increase rigidity. It is a sustainable alternative to plastic straps as it can be reused, recycled, and composted after use.

Eco-friendly and biodegradable packaging materials made from sugarcane bagasse that are sustainable, flame retardant, mechanically robust, thermally stable, and have low environmental impact compared to plastic alternatives. The process involves delignifying the bagasse, phosphorylating it, homogenizing, sonicating, casting, freezing, and freeze-drying to create films, aerogels, boards, boxes, plates, and sheets. The phosphorylation step enhances the properties like solvothermal stability, degradation resistance, and flame retardancy.

Mattress packaging that reduces waste and environmental impact by replacing plastic with paper and a coating. The mattress is packed inside a box with at least one layer of paper. The paper has a mass of 80-130g/m2 and a mass ratio of 90-99% paper to 1-10% coating. The coating is weldable material on one side of the paper. This provides strength and tear resistance without plastic. The mattress cover is made of spacer fabric with recesses to reduce weight. The cover has a natural fiber upper layer and synthetic lower layer. The mattress itself has zones for head, neck, shoulders, lumbar, and pelvis support.

Eco-friendly cushioning packaging material made from natural pulp like sugarcane and bamboo instead of plastic or wood pulp. The packaging material is manufactured by processing paper made from the natural pulp. To reduce dust generation from the short fibers of sugarcane pulp, a small amount of bamboo pulp is added during fabric production. The paper surface is coated with starch and biodegradable wax to improve strength and water resistance. This allows replacing traditional plastic cushioning materials with a more sustainable option that reduces plastic usage, carbon emissions, and environmental pollution.

A process for manufacturing biodegradable and compostable packaging material from flower waste. The process involves extracting cellulosic substance from dried flower waste using sodium hydroxide, then combining it with a water-soluble polymer, adhesive, epoxy resin, and hardening agent to form a viscous solution. The solution is stirred, pressed, and cured to create the biodegradable packaging material. The flower waste-based packaging is compostable and degrades easily when buried.

Preparing a grass-derived multifunctional nanomaterial film for food packaging that enhances mechanical properties, water resistance, UV protection, oxygen scavenging, and antimicrobial properties. The film is made by incorporating nanomaterials extracted from dried darbha grass, like carbon dots, cellulose nanofibers, and silver nanoparticles, into PVA films. The grass nanomaterials improve the film's performance compared to standard PVA films.

A packaging bag for displaying foods in stores that is environmentally friendly by using materials like glassine paper instead of synthetic resins. The bag has a glassine paper section for transparency to show the contents and a separate section made of more breathable paper. The two sections are heat sealed together to form the bag. This allows air permeability and visibility while avoiding synthetic films. The bag can be a bottom gusset or three-sided style.

Process to make biodegradable bottles using natural materials like areca leaf and cellulose bio-polymer. The process involves cleaning and soaking the areca leaf sheath, drying it, compressing it with cellulose film to form a biodegradable material, thermoforming into bottle shape, and trimming. The resulting biodegradable bottle reduces plastic waste and promotes environmental sustainability compared to conventional plastic bottles.
