Listed with other top experts in: |
|
Expert has over 40 years experience in both theoretical and practical properties, applications, and processing of materials for use primarily in the flexible packaging area, but also in many industrial areas, such as stretch film, siding, automotive applications, etc. He has worked extensively with acetate ethylene copolymer, acrylic resin, ethylene copolymer, ethylene resin, ethylene propylene copolymer, ethylene vinyl acetate, E-CTFE, ionomer, nylon, olefin copolymer, PCTFE, polyethylene, polyethylene terephthalate, polyolefin resin, polypropylene, polystyrene, polyvinyl chloride, and polyvinylidene chloride. His knowledge also includes many other thermoplastic resins, for example polycarbonates, PBT, and metallocenes.
|
|
|
Expert has over 30 years experience in developing packaging films to meet specific barrier requirements, which could be for either low, high, or a specified gas or water vapor permeability. Examples include fresh pre-cut salad packaging film, containers for shelf stable foods such as applesauce, and metallized or saran coated films for high barrier applications. He also has done extensive work to minimize water vapor transmission in cereal bag applications.
|
|
|
Expert has extremely detailed knowledge of film and extrusion coating processes, particularly in cast film coextrusion and production of PVC an PE shrink films by the orientation process. He has worked with the largest cast coextrusion line in the world, which produces 200,000 lbs. of 1 mil film per day. His extrusion knowledge dates back to 1960 at Metal Box (UK), where the first OPP line was started up in 1963. He has worked specifically with extruded multilayer polyethylene and polypropylene films and their copolymers in conjunction with barrier resins and other polymers. He also worked extensively with nylon and fluorinated polymers at Honeywell (Allied).
|
|
|
While not as intimately detailed as cast film, Expert has highly detailed knowledge of blown film and sheets extrusion processes. He has spent considerable time developing food grade rigid PVC sheet, PET sheet, and barex sheet for meat packaging applications and PP/EVOH/PP for thermoformed containers for shelf-stable food. While at James River/Printpack, Expert gained secondary expertise in polymer film laminates, aluminum laminates, flexible packaging laminates, flexible packaging printing, laminating machinery, and bag manufacturing. James River/Printpack is the country's leading producer of printed laminations manufactured by extrusion lamination and adhesive lamination. Expert has been heavily involved in developing films for use in these materials and has a good working knowledge of the equipment and processes involved, dating back to ground-breaking work with Metal Box in the 1960s.
|
|
|
Expert has experience in EVA, EMA, and EAA ionomer resins which he has used primarily in heat seal layer design, or to achieve specific oxygen transmission rates.
|
|
|

|
|
|
Expert has experience with EVA coploymers with 2-28% VA in heat seal layers, shrink films, etc.
|
|
|
Expert has 40 years experience in blown and cast films,
including 9-layer coextrusions. 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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.

| 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.
