Troubleshooting Single-Screw Extrusion . . .

Abstract:  Coextrusion is a complex process where many processing and structure design factors affect performance. As a result, problems can be difficult to troubleshoot. This presentation explores some of the recent advances in the science of coextrusion, with a focus on using this knowledge to prevent and troubleshoot problems. Issues involving multilayer film design and properties (compared to monolayer films), curl and adhesion are discussed.

Comparsion of Water-Quench vs. Air-Quench Blown Film Processes - Part I
Abstract:  Investigating the film property differences between water-quench versus the traditional air-quench blown film process - the effect of process parameters such as water ring position, water temperature and annealing temperatures on the final film properties were studied.  Barrier properties such as water-vapour transmission rate (WVTR) and oxygen transmission rate (OTR) were compared as well.  Results were correlated to the crystallinity differences observed between the samples using optical microscopy and WAXD.
Comparsion of Water-Quench vs. Air-Quench Blown Film Processes - Part II
Abstract:  Investigating the film property differences between water-quench versus the traditional air-quench blown film samples.  In Part I, it was found that the overall crystallinity of the water-quench film was much lower than that of the air-quench film.  This resulted in higher WVTR and OTR values. The effect of process parameters such as water ring position, water temperature and annealing temperatures on the final film properties were found to be insignificant.  In the second part of this study, thermoformability of the samples will be investigated in detail.  Thermoforming trials were performed on both a batch former and an automated Multivac thermoformer.
New Film/Sheet Technologies . . . Antistatic Performance of
K-Ionomer Blends
Abstract:  K-ionomer antistatic agent is highly effective in polyolefin host resins. In addition to the many unique features it imparts to the end-uses, the K-ionomer shows good compatibility with polyolefins and is easy to process. This presentation includes an in-depth discussion on several material and processing factors that must be properly controlled in order to achieve a favorable blend morphology and further improve the antistat performance.

packaging film production
Package Development . . . Application of Modeling . . .
Abstract:  Models developed by DuPont or found in the literature are described that help the package engineer design new package structures by optimizing package performance, minimizing cost and ensuring the film or laminate can be fabricated on converting equipment. A case study is presented to illustrate how the use of these tools can speed up new package development.
