Raw Material Blending for Package Production

Eco-friendly vinyl packaging material that replaces aluminum and starch, decomposes over time, and reduces greenhouse gas emissions when incinerated. The packaging material contains a blend of high-density polyethylene (HDPE), low-density polyethylene (LDPE), biodegradable bionyl, and additives like stearic acid, copper, manganese, zinc, calcium carbonate, softener, and octene. The bionyl includes ethylene vinyl acetate (EVOH), a biodegradable mixed powder, and an oxidative biodegradable catalyst. The packaging is manufactured by extrusion and stretching the blended material. It can be used for food and cosmetics packaging that decomposes over time and reduces environmental impact compared to traditional vinyl.

Sheet for press-through packaging, like for medicine blisters, with improved properties for environmental friendliness and manufacturing ease. The sheet contains vinyl chloride resin, biomass resin, and a plasticizer. It has a specific storage modulus range of 1-2.6 GPa at 30°C. The biomass resin is a butylene succinate like polybutylene succinate. The plasticizer is epoxidized vegetable oil like epoxidized soybean oil. The vinyl chloride resin has low chlorine content. This composition allows manufacturing press-through packages with biomass content over 10% and reduced bleeding of plasticizers during production.

Blow molded bottle container with improved thin-wall thickness, drawdown resistance, and burr removal properties. The container has a specific ratio of bio-based polyethylene, high density polyethylene, and linear low density polyethylene. The ratio of bio-based polyethylene to total polyethylene is 20-50%. The ratio of (bio-based + high density):linear low density polyethylene is 40:60 to 60:40. This composition allows thin-walled containers with reduced deformation and burr retention compared to conventional containers. The thin-walled containers have better drawdown resistance and easier burr removal during molding.

Degradable plastic bottle made from a unique blend of biodegradable polymers that improves the mechanical properties and barrier performance compared to existing degradable bottles. The bottle is blow molded from a resin mixture containing PLA, PBAT, PPC, PGA, and calcium carbonate. The PPC and PGA polymers enhance the crystallinity of the PLA, improving its strength and barrier properties. The degradable bottle can hold pesticides without leaching solvents due to the higher crystallinity PLA.

Biodegradable and compostable bioplastic packaging made from local agricultural materials like fibers, oils, and essential oils. The packaging is cheap, biodegradable, and active due to the incorporation of essential oils. The process involves converting agricultural fibers like raffia, sisal, and pineapple into cellulose acetate. This is mixed with polylactic acid, edible oils, and essential oils, homogenized, and dried into film.

Active biodegradable plastic packaging film made from pear waste that has improved mechanical properties, UV barrier, oil barrier, and biodegradability compared to conventional plastics. The film is made by combining mashed pear peel and pulp extract, starch solution, and glycerol. The pear waste acts as a filler to enhance properties, starch as a crosslinking agent, and glycerol as a plasticizer. The film is cast and cured to create a biodegradable packaging material with functional properties like antioxidant activity and moisture control. The film can be used in food packaging, pharmaceuticals, and other applications requiring sustainable and active packaging solutions.

Biocomposite packaging material made from high density polyethylene (HDPE), red seaweed powder, and coconut coir powder. The composite is manufactured by mixing the three components in a rheomixer at specific temperatures, speeds, and times. The resulting biocomposite has properties like tensile strength, modulus of elasticity, and melting temperature that exceed those of pure HDPE. The seaweed and coconut coir additives improve the composite's mechanical and thermal performance. The process involves melt mixing HDPE, seaweed powder, and coconut coir powder in a rheomixer at temperatures around 135-145°C for 5-10 minutes. The resulting biocomposite blocks are then injection molded into packaging products.
