When recycling post-consumer paper, stickies are tacky substances contained in the paper pulp and process water systems of paper machines. Stickies have the potential to contaminate the components either within or around the equipment necessary in the Stages of Manufacturing that a Paper Mill follows in its Developed Process, but would have otherwise excluded it in its routine cleaning and maintenance procedures. Contaminations of paper that are classified as tacky are also called stickies. The main sources for stickies are recycled paper, waxes, and soft adhesives. ==Composition== Stickies are an indefinite mixture of organic compounds, with the main part being different esters. The components might stem from: *Printing inks *Coating binders (synthetic latex) *Waxes *Hot melt adhesive and unsupported pressure-sensitive adhesives *Plastics *Wet strength resins *Pitch *Papermaking additives 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stickies (papermaking)」の詳細全文を読む スポンサード リンク
