Materials giant Dow Chemical announced that with new technology "RecycleReady" successfully deciphered recycling multilayer package bag password. It is reported that the technology is applicable to a particular bag design .
However , Dow is responsible for packaging and specialty plastics global development leader Lamy Chopin is expected , which will lay the new trend of development of composite plastic bag recycling .
With RecycleReady, Dow uses Retain brand compatible agent , polyethylene (PE) and vinyl alcohol copolymer (EVOH) while renewable , generate useful material back film.
Plastic film is also very common available in PE and EVOH i, abut it’s a headache for recycling company , because EVOH barrier layer sandwiched between the PE layer,it will be sticked during reprocessing, and it will result in the formation of holes on the regeneration of PE film.
"This is a serious matter , in one fell swoop changed the rules of the game than ever . We can put everything together recycled , not only retains the advantages of the isolation layer , and can be recycled , great. This up and down the value chain for many people good news . " Dow Chemical North American plastic packaging and specialty packaging solutions director Stacy Fields representation .
Fields said: "For the plastics manufacturer, we gave them a choice , not only to meet sustainability requirements, but also meet the requirements of the brand or retailer for recycling companies, they do not need special treatment, directly . recycling can be . "
He said in global forum " This technology gives customers the right to choose , so that they participate in the recycling process ."
Retain Dow was originally developed to help post-industrial regeneration PE and EVOH film , so that when the recovery is compatible with EVOH PE.
Chopin said: "We started RecycleReady project, realize that you can bind directly to Retain recyclable film , rather than added to it after the completion of which allows us to design both the isolation characteristics of the film is completely recyclable ,The isolation characteristics are brought by EVOH . " EVOH recycling industry have no worry about pollution .
US Sustainable Packaging Coalition and the plastic recycling industry associations have endorsed the Dow technology.
Users can display technology RecycleReady How2Recycle Union label on the packaging , consumers see the label you know these bags can be recycled into the trash .
"Now the recycling industries do not have to worry , because it has been compatible with polyethylene , especially the retail outlets of waste plastic recycling ," Chopin said.
He said: " We think this is an important first step , we will continue to advance , we have established the concept and collaborative process and we plan to bring new compatible agents such as polypropylene as other materials that can strengthen the packaging. bag performance , and can successfully complete the recycling process . "
Packaging industry has been grappling with composite plastic bags deal with the problem of old age . Due to the design of complex , and sometimes includes a metal layer , many package bag are directly discarded . Dow RecycleReady hopes to change this situation .
