This study analyzes the combination of different tie layers with normal coextrusion and coating parameters: temperature, speed, and pretreatments. We wanted to determine the best combination possible and to issue recommendations for extrusion and coating. The typical structure was paper/tie layer/barrier layer/tie layer/LDPE (low-density polyethylene). When LDPE is coated on paper, pretreatments of the web are used (such as corona or flame). Sometimes ozone is sent onto the melt to increase natural oxidation. The same thinking could be applied to tie layers, but the trials showed that certain combinations lead to different conclusions. The effect of parameters such as corona or flame power, which were thought to depend only on the paper type, could also be influenced by the combination paper-tie layer. This could mean that web pretreatments are not always needed.

With increasingly stringent EPA guidelines for controlling emissions of volatile organic compounds on the horizon, the desirability to move to water-based printing inks is evident This paper examines the effects of corona discharge treatments which are commonly used to improve ink adhesion to polvethylene. Electron spectroscopy for chemical analysis (ESCA) was used to determine the surface chemical changes induced by corona treatments in pure polyethylene extruded films and in formulated resin systems This data was correlated with surface tension and ink adhesion measurements to show the effects of treatment and additives on the final printability of the films with particular emphasis on water-based inks. In addition, the effects of stonng treated film prior to printing and of retreating these films were also examined The results of these tests have shown that formulated linear low density polyethylene (LLDPE) films treat and print at least as easily as high-pressure low-density polyethylene (HP-LDPE) counterparts.

Water absorption by the basestock during coating affects coating pickup and coating mass distribution and, thus, the properties of the coated paper. This work presents results of experiments that were designed to separate the effects of two important factors that determine sheet absorbency: hydrophobic sizing and porosity. Bleached kraft handsheets with a broad range of pore size, void fraction, and roughness were sized to different levels with a solution of alkyl ketene dimer (AKD) in non-swelling hexane. A lightweight coated (LWC) basestock was treated similarly. Coating was performed at 762 m/min on a cylindrical laboratory coater. The effect of hydrophobic sizing on coating pickup depended greatly on sheet porosity and roughness. On dense-smooth sheets, sizing resulted in lower coating pickup. On rough sheets, including LWC basestock, the effect of sizing on pickup was concealed by the overwhelming effect of roughness on the metering action. Coating uniformity and holdout were very good on the dense-smooth sheets (although sizing gave a slight reduction) and poor on the porous rough sheets and LWC basestock (sizing had little effect). The results suggest that coating holdout and uniformity are determined mainly by sheet surface structure (porosity and roughness) and not by sizing.

The technique of inverse gas chromatography (IGC) is used to investigate and compare the surface chemical properties of chlorine dioxide-bleached pulps with peroxide- and ozone-bleached pulps and to study the influence of a latex binder (with dispersant) on the properties of calcium carbonate coating particles. IGC measurements with a series of alkane probes yield the dispersive component of the surface energy of the test solid and show only small differences between the various bleached pulps. The use of acid and base probes shows all pulps tested to be predominantly acidic. The presence of latex binder together with a poly (acrylic acid)/carboxymethyl cellulose dispersant decreases the dispersive component, but increases both the acidic and basic components, of the surface free energy of calcium carbonate.

The trials documented in this paper were run on a pilot coextrusion coating line at the Tampere University of Technology's Institute of Paper Converting in Finland. The study was conducted to test the ozonization system that was installed in our pilot line to treat the polymer melt in extrusion coating. The effect of the ozone, generated at the corona treater, on adhesion was studied. Ozone was first captured and transported to the nip with separate pipes. It was then led to an air knife near the air gap and blown against the polymer melt. The measured adhesion showed the usefulness of this technique. The following parameters were varied to determine the effectiveness of the ozone: substrate, line speed, coating weight, and melt temperature. Results indicated that thicker coating weights and higher melt temperatures improved adhesion values. The corona-generated ozone clearly improved adhesion compared to corona-treated or untreated samples.

With the advent of readily available nonpaper substrates (plastics and foils) in the mid-to-late 1950’s, the requirement for a reliable production speed surface treatment process became apparent. Several different technologies have been tried, but one, corona treatment, has become, by far, the primary surface treatment technology used across the Extrusion and Converting Industries. We will touch on these various technologies, technically describe the need for surface treatment and how it is measured, trace the development of corona treatment as the leading surface treatment method, and detail the current state-of-the-art in equipment, control parameters and applications.
