Pet Bottle Recycling Process in China
Core pin and other gaps, so that residual air rapidly discharged.Moreover, can reduce the material temperature, reduce the injection speed and injection pressure or increase the size of the gate.
13: Black Streaks (Black Streaks) refers to the phenomenon of black stripes molded products, the main reason for its occurrence is due to thermal decomposition of molding materials, common in poor thermal stability of the material.
Britain has developed a water-soluble plastic packaging
British scientists have developed a new type of plastic packaging products that can dissolve in water. A company called Cyberpac, unveiled its new blend of Harmless-Dissolve in the UK’s private innovation initiative by signing a trade agreement with the industry’s magazine Creative Review. Ester packaging system.
Since the release of the packaging claiming to be “water-soluble”, a large number of websites around the world have focused on their information, and blog sites around the world, especially those focusing on environmentally friendly products, are posting a blog post about it .
According to reports, some of the polymer plastic takes hundreds of years to break down, which means that human production of plastic will exist in the earth for a long time. Eighty percent of all plastic waste used by consumers is ultimately transported to landfills and only 7 percent is recycled. In the UK alone, the country produces 30 million tonnes of domestic waste each year, of which 5.9 million tonnes are packaged goods. In Scotland, from 96% of the dead gull’s stomach can be found in plastic waste.
The bag says it can be dissolved in water.Today, this “harmless decomposition” of new plastic packaging products from the hydropower decomposition of the matrix, the strength of polyethylene than the average 5 times higher. It is a water-soluble polymer that can be completely biodegraded in a composting environment, dishwasher or washing machine.
This packaging product has no harmful residues, and will break down into insects like the natural material. It is non-toxic and can be degraded by microorganisms, molds and yeasts.
These organisms can exist in artificial environments such as anaerobic digesters, as well as compost and natural environments such as aquatic systems and soils. Microorganisms serve as a food source by producing enzymes that interact with & quot; harmlessly decomposable & quot; Ultimately, the bags become carbon dioxide, water and biomass. In this case,
A company spokesman said the “harmless decomposition” will bring an industry: a very diversity and flexibility of fully biodegradable bags. “It can be made in many colors and styles — ‘harmless’ can be made into any size of the envelope, with biodegradable ink for full-color printing, and finally to the biodegradable coating and lip seals to complete “We have relationships with the military, the aerospace, pharmaceutical and automotive industries, and the ability to master the packaging processes in these areas to deliver the most innovative and innovative solutions,” he said.
For some time, the UK packaging industry has been garbage prevention as a design concept. Packaging design and production technology improvements can save a lot of material. For example, glass milk bottles are now 65 percent lighter than in 1940, and 1-liter plastic detergent bottles are 58 percent lighter than in 1970. Cartons are 14 percent lighter than in 1971.
