Ing-Mari
Pettersson, graduated in
1987 at
The
Royal Institute of Technology (KTH), Stockholm Sweden, with a
Master of Science in Engineering in Metallurgy and Materials
Technology specialisation Polymer Technology.
Joined
Dow Benelux N.V. in Terneuzen, The Netherlands, in 1988 with the
research and development department of STYRON / Engineering
Thermoplastics, working with technical service and development of
engineering thermoplastics toward the Automotive industry as well
as with general application engineering and development.
Transferred
to Dow Deutschland GmbH & Co. OHG and the department of
Fabricated products in 1995. Has worked with technical service and
development of numerous film materials as well cushion packaging
foam materials. Since 1997 working on application and product
development for speciality olefin films and currently project
manager for film development projects on the technology platform
of COVELLE HF weldable olefin films.

Abstract
High
frequency (HF) welding has traditionally relied on the inherent
properties of flexible to achieve film performance properties of
polyethylene films with HF activity comparable to that of flexible
PVC led to the development of a new family of films – COVELLE
HF weldable polyolefin films.
Originally
developed for the use in medical collection bags the technology
has further evolved to find use in additional medical device
applications, as well as enabling technology for HF inactive
substrates and as HF active transfer media.
The
additional feature of thermally activated adhesion allows COVELLE
film to provide HF activity to substrates that are not inherently
HF weldable such as polypropylene and polyester non-woven, natural
and synthetic woven fabrics, PU foam, paper, cellulose boards and
others. This has opened opportunities in a wide range of
applications including automotive interior trim.
