Course# Date Time Location
207-1336 08/14/2024 - 08/16/2024 8:00 AM - 11:00 AM Microsoft Teams
Cost: $1,800 USD
Online Registration
CEU's: 1.8
Instructor: Dr. Sylvain Seif

Course Overview

The course is meant to give a comprehensive overview on blown film extrusion processing of various polymeric resins, with focus on structure-processing-properties relationships. Various monolayer as well as co-extruded multilayer film applications will be discussed in detail, mainly for the medical sector; including biohazard bags, monolithic and microporous medical garments, water-soluble bags, and super hexene bags. Usage of polymer blends, microcomposites and nanocomposites, as well as renewable and biodegradable materials will also be elucidated for such applications. Filles and additives used to enhance certain features of these packaging materials will also be investigated, along with typical loading levels and application methods. The course will also detail the physical, mechanical, thermal, and barrier properties of blown film extruded medical products, and experimental tools and methods to measure these properties. Sustainability, recycling, and regulatory issues of these films will also be discussed.

Instructor Biography:


Dr. Sylvain Seif has over 15 years of industrial R&D experience in Polymer Engineering, spanning several different areas in the field, and over 12 years of academic teaching experience. He completed a BS in Mechanical Polymer Engineering in 2005 followed by a PhD in Polymer Engineering degree in 2009 from The University of Akron in OH, USA. After graduation, he joined INDEVCO Group, a multinational packaging and consumer goods firm, starting up an R&D Center called “PACT”- Polymer Application Center for Technology- for the entire flexible packaging and compounding divisions of INDEVCO, which consists of 10 manufacturing facilities spread across the globe. He has also taught several engineering courses at the university level, and started R&D collaborations with 5 different universities, refereeing over 30 Masters and Final Year Projects, and being a jury member on all these projects. In 2017, as Senior Technical and R&D Expert at PACT, he helped the INDEVCO R&D Center attain ISO 17025 accreditation for lab testing.

Since 2022, Dr. Seif has been working at an environmentally conscious start-up company, Novoloop, in California, managing the polymer processing lab; having expertise in operating the twin screw compounder, injection molding and co-extrusion cast film machines. Here, he optimized the processing and properties of various durometer TPUs, whereby the polyester polyols are derived from PE recycled waste. He is also very familiar with structure-processing-properties relationships of polymers and their composites, with a strong know-how in lab testing methods for mechanical, rheological, thermal and physical properties. Moreover, Dr. Seif has over 10 academic publications and 3 patents in the polymer field, and has a strong passion for teaching and doing research and development in sustainable solutions.
