How proper treatment for flexible laminates helps achieve high bond strength, zero optical defects
By Kirsten Lykke, consultant-Polymers & Flexible Packaging Technology for Vetaphone A/S This article discusses the main criteria for high-quality lamination used in today’s flexible-packaging sector and the role that surface treatment plays with sophisticated substrates. Lamination requires two essentials: bond strength and zero visual defects. Fundamental to both is the … [Read more...] about How proper treatment for flexible laminates helps achieve high bond strength, zero optical defects
“Nitro-Hydro-Flame” treatment technology for polymer surfaces
By Stefano Mancinelli, sales & process mgr. EsseCI s.r.l. Some substrates, such as plastics, have inert and non-porous chemical surfaces that make them non-receptive to the affixing of various materials, such as printing inks, adhesives and coatings. Surface treatment increases the surface tension (wettability) of the material to prepare it for subsequent applications, … [Read more...] about “Nitro-Hydro-Flame” treatment technology for polymer surfaces
Using excimer technology as an alternative surface treatment for highly sensitive, costly substrates
By Chris Davis, head of sales for Web & Industrial Systems, IST America This article will detail an alternative method of modifying (activating the) surface energy of materials; in particular, highly sensitive (and costly) substrates. Materials such as functional films, wafer materials, thin and heat-sensitive films all require full consideration when using traditional … [Read more...] about Using excimer technology as an alternative surface treatment for highly sensitive, costly substrates
