Degradable plant starch-sodium caseinate composite packaging film for fruits and vegetables

InactiveCN104610581AEasy to degradeStrong physical and mechanical propertiesFlexible coversWrappersCitrate sodiumZinc sulfide

The invention discloses a degradable plant starch-sodium caseinate composite packaging film for fruits and vegetables and relates to the technical field of packaging films for the fruits and the vegetables. The packaging film is prepared from raw materials in parts by mass as follows: 80-90 parts of plant starch,40-50 parts of sodium caseinate, 15-20 parts of cloves, 15-20 parts of propolis, 15-18 parts of nano calcium carbonate, 12-15 parts of fumed silica, 10-12 parts of polyvinyl alcohol, 8-10 parts of sodium alginate, 8-10 parts of epoxidized soybean oil, 6-9 parts of zinc sulfide, 5-8 parts of konjac glucomannan, 5-8 parts of low-methoxyl pectin, 3-5 parts of sodium citrate, 3-6 parts of agar, 3-5 parts of genipin, 2-3 parts of polyglycerol fatty acid ester and 800-1000 parts of water. The plant starch and the sodium caseinate are used as main raw materials, and various aids are used as auxiliary materials, so that the produced packaging film has higher physical and mechanical properties, selective permeability and antibacterial and anti-oxidation effects; besides, the selected raw materials can be degraded easily, so that the ecological environment is protected.

Environment-friendly modified polyvinyl chloride tight buffering material for soft communication optical cable and preparation method of material

InactiveCN104312057AOutstanding high temperature resistanceHighlight environmental protectionShrinkage ratePlasticizer

The invention discloses an environment-friendly modified polyvinyl chloride tight buffering material for a soft communication optical cable and a preparation method of the material. The material comprises the following raw materials in parts by weight: 95-100 parts of polyvinyl chloride resin, 30-35 parts of an environment-friendly plasticizer, 5-8 parts of a cold-resistant plasticizer, 5-8 parts of an environment-friendly stabilizer, 20-35 parts of a filling agent, 3-8 parts of a flame retardant, 0.5-2 parts of a lubricant, 4-9 parts of an anti-impact modifier and 3-5 parts of an anti-heat shrinkage modifier. Due to the addition of the cold-resistant plasticizer, the material is outstanding in high temperature resistance, low temperature resistance and environmental protection property; due to the anti-heat shrinkage modifier, the material is relatively low in heat shrinkage rate; due to the flame retardant, the material is relatively good in flame retardant property. According to the preparation method, the process is simple, the temperature is reasonable, and the produced material is guaranteed to be relatively good in flame retardant property, high and low temperature resistance and small in heat shrinkage rate.
