This technology advances the use of aqueous PHA coatings as a replacement for less environmentally friendly extruded plastic and fluorotreated packaging papers and boards. The new technology utilizes short burst photonic energy to heat PHA latex coatings. Utilizing a rapid pulse of photonic energy enables PHA particles to melt and form a film within milliseconds, as compared to conventional equilibrium drying that takes several minutes. Coatings were applied to commercially produced papers in order to validate the combined use of photonic treatment technology with PHA materials for commercial applications. Photonic treatment for both bench-top and roll-toroll pilot-scale studies resulted in kit values of 12, and 2 min Cobb values of <2 g/m2. Repulpability studies showed the material to be completely repulpable, having 100% accepts after screening. The results demonstrate that the photonic treatment of PHA polymers could be used in current commercial settings to produce environmentally friendly packaging and coated products.","PeriodicalId":337719,"journal":{"name":"Octobr 2018","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114310805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An ISO brightness drop of 1–3 points is often experienced. There are many reasons for the brightness loss; however, the usual suspects tend to be water quality, metallurgy, and process chemicals. One bleached paperboard mill in the southern United States had been experiencing brightness losses in the 6–8 point range for several years. A systematic study was conducted to determine the potential sources for this brightness loss. A laboratory simulation technique was developed to demonstrate the potential causes for the brightness loss along the process.","PeriodicalId":337719,"journal":{"name":"Octobr 2018","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122260266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
