1. Disposable meal boxes based on degradable composite packaging materials
Introduction: This technology provides a disposable meal box based on degradable composite packaging materials, which belongs to the field of degradable materials technology, including the molding of degradable composite packaging materials through the selection of free extrusion, hot molding, injection molding, blow molding, rolling, compression molding method and transfer molding method in the group of processes; The degradable composite packaging materials are made of activated straw powder treated with strong alkali solution, ethanol solution containing silane coupling agent and polymaleic anhydride, polylactic acid and additives by mixing and granulation. The technology can be degraded composite packaging material has high tensile strength, bending strength and impact strength, low surface viscosity and melting temperature, better processing performance, can be completely degraded in the natural environment, 30 50 days of natural degradation rate of 89%, 100 180 days of natural degradation rate of 100%.
2.The utility model relates to a degradable disposable takeaway food box and its formula technology
Introduction: The technology provides a degradable disposable takeaway box and its formula technology, which relates to the field of degradable materials, including an inner film and a box body, the inner film is a food-grade polyethylene film, the box body is made of the following weight of raw materials: High porosity rate polyurethane foam powder 30 50 parts, epoxide lignosulfonate 10 20 parts, linear low density polyethylene 30 40 parts, poly (lactic acid) 12 18 parts, bagasse 20 30 parts, modified peanut shell 150 200 parts, ethyl cellulose 5 10 parts, starch 10 15 parts, sucrose ester 15 parts, compound antioxidant 0.2 1 The mechanical properties of the lunchbox prepared by this technology are excellent, and the insulation performance is good, water resistance, high temperature resistance, long time high temperature water immersion, has little influence on its mechanical properties, has a fast degradation rate in the soil, 90d mass loss rate is greater than 40%, green environmental protection, help to improve the white pollution.
