A Review of Transparent Barrier Coatings Paid Members Public
Presented by B.M.Henrey, University of Oxford The transparent barrier films presently available on the market all have their strengths and weaknesses. At the same time there is consideration to use more plastic-based materials for different applications, e.g. displays and insulation panels. This situation has stimulated the industry
Enhanced Water Vapour Permeability Tester for High Barrier Materials Paid Members Public
Presented by Alyce Hartvigsen, PBI Dansensor The newest developments of barrier materials for packaging of water vapour-sensitive food products and other specialized applications such as organic light-emitting diode (OLED) films have led to the achievement of lower water vapour transmission (WVTR) rates through the materials. The WVTR rates of these
High Performance Copolymer Dispersions for Flexible Packaging Paid Members Public
Presented by C. Guy, Michelman Traditional ethylene acrylic acid copolymer dispersions require the presence of a primer on many non-polar substrates in order to achieve proper wet out and adhesion. This article will describe how new dispersion developments have evolved and discuss the high performance properties now delivered on a
Nanocomposite Barrier Coatings Paid Members Public
Presented by Harris A. Goldberg, InMat Inc. InMat® has developed an exciting new class of environmentally friendly aqueous based barrier coatings that combine exfoliated layered silicates with polymers. Its first product designed for the packaging industry, Nanolok PT, has an oxygen permeability of ~0.002 cc-mm/m2-day-atm. This means that
Scale up of a Coating Process Paid Members Public
Presented by E. Lawrence Gogolin, Gogolin & Associates When you scale up a process for coating, from the lab bench to manufacturing, there are many potential pitfalls. The problems can come from many sources. Among them are: the coating fluids and variability in the batches of their raw materials, the
The Effect of Retort Conditions on Clear High Battier Laminated Structures Paid Members Public
Presented by Dante Ferrari, Celplast Metallized Products Ltd. Retorting refers to the thermal sterilization of low-acid foods, to extend shelf life by killing bacteria and other microbial species in the food. It has traditionally been used to preserve foods packaged in metal cans or glass jars. Following WWII, flexible retort
New Microwave Technology for Uniformly Heating, Drying, and Curing Coatings and Laminants Paid Members Public
Heating is the most fundamental process in industrial manufacturing. It is used for drying, promoting chemical or physical change such as bonding and curing, and many other purposes. Despite this, heating remains one of the most difficult processes to control. It is slow and imprecise when implemented in the conventional
Discharge Voltage Variations when Switching from Pure Metallic to Poisoned Sputtering Paid Members Public
Presented by R. De Gryse, Ghent University It is commonly assumed that the Ion Induced Electron Emission coefficient (ISEE or gi) of oxides has a higher value as compared to the bare metal and one expects lower discharge voltages VD at constant current when sputtering these metals in poisoned mode.
