He has extensive rheology problem-solving skills associated with a 180-inch-wide, 5-extruder cast line running at 1700 FPM making 1 mil film. He has used computer simulations to select appropriate resins.
nylon film expert	Expert has 12 years' experience at Allied Signal (Honeywell) extruding Nylon 6 and Nylon 66 cast films for meat packaging. He developed a reclaim process, Saran coating, and release films for SMC and other applications.
packaging film expert	Expert has 40 years of experience with five companies in a technical capacity involved in designing, testing, manufacturing, and application development of films used in the packaging industry. He was involved all commonly used thermoplastics as well as some of the more exotic ones, e.g., PCTFE, E-CTFE, PVDC, PC, Nylon 6, and PET.
polymer coextrusion expert	Expert worked in R&D at James River (ex Crown Zellerbach) on blown and cast die design. He used rheology programs for resin selection. He carried out development on the world's widest cast coex line in New Castle, Delaware for 9 years. He ran the blown film coextruder in Greensburg, Indiana.
polypropylene extrusion expert	Expert had nine years of experience in New Castle, Delaware extruding cast propylene films. He also had two years' experience in extruding OPP with Metal Box in the U.K.
polyvinyl chloride extrusion expert	Expert worked with rigid and flexible PVC extrusion at Mobil, including extruded profiles, sheet, and films. He worked 12 years at Allied developing oriented PVC shrink films, rigid and flexible (Krystaltite (TM)). He also developed food grade sheet for meat packaging. At Templock, he developed a process for very small diameter rigid shrink tubing for dry cell battery construction, as well as tamper-evident bands.

Consulting Services:

Selected Consulting Examples:

Expert has visited many customers who have experienced problems in converting his company's packaging film. He has shown them how to increase machine speeds and efficiencies through correct film selection, adjustment of temperature profiles, and selection of correct design of sealing jaws. A specific example would be increasing production speeds at Pillsbury's Pie Crust packaging by 100% through modification of the heat seal layer resin and improved temperature control on their heaters.
He resolved an edge curl problem on PVC shrink tubing that was affecting dry cell battery production by changing the tubing manufacturing method. Tubing was being shock cooled in a cold water bath, resulting in external stresses in wall of tube. The die was modified to accept internal cooling mandrel.
Metallocene sealant layers were causing severe slip-stick problems on VFFS machines packaging precut salad, although ASTM tests showed Film-steel COF was 0.2. Found at higher sled loadings, COF was 0.5, so they increased slip levels, but also changed the antiblock type to one with some larger particles and less slip absorbent.
Expert has conducted many audits of polymer production facilities (e.g., Chevron, Amoco, Montel, DuPont, Exxon, etc.) to determine suitability for use. In doing so, he became familiar with polymer manufacturing methods and was able to delineate suppliers.
