  • Occurrence of Reverse Side Effects in Corona Treatment of Dispersion
    RESEARCH ARTICLE Occurrence of Reverse Side Effects in Corona Treatment of Dispersion-coated Paperboard and its Influence on Grease Barrier Properties PREFACE API 2015 Sami-Seppo Ovaska Ringaudas Rinkunas Lappeenranta University of Technology Vilnius University [email protected] [email protected] Tadeusz Lozovksi Robertas Maldzius Vilnius University & University of Bialystok Vilnius University Vilnius Branch [email protected] [email protected] Jonas Sidaravicius Leena-Sisko Johansson Vilnius Gediminas Technical University Aalto University [email protected] [email protected] Monika Österberg Kaj Backfolk Aalto University Lappeenranta University of Technology [email protected] [email protected] ABSTRACT The uncoated side of dispersion-barrier-coated paperboards was exposed to positive and negative direct current corona treatments in order to confirm the occurrence of backside treatment and clarify its effects on the usability of the paperboard. The main component of the coating dispersions was hydroxypropylated potato starch and the effects of talc and styrene-butadiene latex additions on backside treatment were evaluated. Coatings with a high talc proportion showed excellent initial grease resistance, but corona-induced strikethroughs caused a drastic decrease in grease penetration time. The root-mean-square roughness measurements revealed moderate surface roughening at the backside, indicating thus backside treatment. The alterations in surface free energies and rapeseed oil contact angles confirmed the occurrence of backside treatment. The high polarization potential of latex played a key role in these observations. At the same time, the inertity of talc had a stabilizing effect but it did not prevent backside treatment completely. X-ray photoelectron spectroscopy results verified that backside treatment occurs also when the barrier-coated side of the substrate is treated with corona, indicating that a dispersion coating layer does not prevent this undesired phenomenon.

  • The Role of Surface Modification in Print Quality Formation
    The Effects of Corona and Flame Treatment: Part 1. PE-LD Coated Packaging Board Johanna Lahti, D.Sc. (Tech.) Mikko Tuominen, Lic. (Tech.) Tampere University of Technology Institute of Paper Converting P.O. Box 541, FI-33101 Tampere FINLAND ABSTRACT The most important function of a packaging material is to shield the product inside the package. Extrusion coated paperboard is generally used in food, medical and cosmetic packages. Extrusion coatings give a barrier against water, water vapour, aroma, grease, oxygen, etc. In addition to barrier properties, heat sealability and printability are important properties in packaging applications. From point of view of printing, the dense and impervious structure of extrusion coatings is challenging: printing inks and toners do not penetrate into the coatings. The durability of the printed image is significant, because the image must withstand various converting operations when the package is constructed. The most common method for obtaining good ink adhesion is to oxidize the surface. Surface treatments are used to change the chemical composition, increase the surface energy, modify the crystalline morphology and surface topography, or remove the contaminants and weak boundary layers. Two widely used methods are electrical corona discharge treatment and flame treatment. These processes generally cause physical or chemical changes in a thin surface layer without affecting the bulk properties. Treatments will increase surface energy and also provide polar molecular groups necessary for good bonds between ink and polymer molecules. In addition to printability, surface treatments also affect the heat sealing properties of extrusion coatings. In this study, the surface chemistry of the extrusion coatings has been modified with corona and flame treatments.

  • Heat-Seal Polyester Films
    Heat-seal Polyester Films This article hopes to explain why the growth in single web heat sealable polyester films provides many benefits whilst helping the packaging industry deliver on packaging waste and recycling targets. Dr John’s Insights Background Polyester (PET) is readily and widely recycled and is a sustainable product contributing to the circular economy. Polyester can be produced from virgin and recycled polymer resin with up to 90% of post consumer waste (PCW). Whilst PET is used as a single product, it is often combined with other materials in a laminated structure which makes recycling difficult. Chemical recycling is growing with the aim to separate mixed plastics and reduce the proportion of plastic waste which ends up in landfill. Polyester Films Oriented polyethylene terephthalate (Polyester, OPET) was not initially produced as a single-ply heat sealable flexible packaging film and required lamination to other films to provide the necessary sealant layer with materials such as polyethylene (PE) or polypropylene (PP). Importantly, the polyester film provides heat resistance, strength and barrier whilst the other film web, to which it is laminated, provides a number of performance functions on the packaging machine. PE and PP films will for example contribute to the moisture barrier, seal integrity suitable for gas flushing, anti-fog or peel functionality etc. PET film is naturally wettable and depending on the starting monomer, the wetting angle or dyne level could be 37/38 or 40/42 dynes [on the non-treated surface]. Surface treatment increases the surface energy of these films and leads to improved wettability of inks, coatings and adhesives.

  • What Is Surface Treatment? PPS Business Partner, Tantec, Is Specialised in Surface Treatment of Polymers by the Use of Plasma and Corona Technology
    What is surface treatment? PPS business partner, Tantec, is specialised in surface treatment of polymers by the use of plasma and corona technology. It is often necessary to bond plastic materials to metals or other plastic materials, or simply print on a plastic surface. In order to successfully accomplish this the liquid adhesive, or ink should be able to wet the surface of the material. And this is where Corona Treatment and Plasma Treatment technologies are necessary. You can learn about adhesion and surface treatment of plastic, by reading the full article by Tantec below. Surface Energy Surface energy, like surface tension is measured in mN/m. The surface energy of the solid substrate directly affects how well a liquid wets the surface. The wettability, in turn, is easily demonstrated by contact angle measurements. The contact angle is the angle between the tangent line at the contact point and the horizontal line of the solid surface. When a liquid droplet is set on a smooth solid horizontal surface, it may spread out over substrate and the contact angle will approach zero if complete wetting takes place. Conversely, if wetting is partial, the resulting contact angle reaches equilibrium in the range 0 to 180 degrees. Surface Wettability Figure 1 to your right helps illustrate the difference between good and poor wettability. The higher the surface energy of the solid substrate in relation to the surface tension of the liquid, the better its wettability, and the smaller the contact angle. In order for a proper bond to exist between a liquid and a substrate surface, the substrate’s surface energy should exceed the liquid’s tension by about 2-10 mN/m.
