Seattle, WA, USA--(Jobwerx)--APRIL 11, 2005--Ticona, the technical
polymers business of the Celanese Corporation, has enhanced its Topas®
COC (cyclic olefin copolymer) to give blown film producers greater processing
flexibility and the ability to make highly transparent films that are
practically free of gels.
Ticona Technical Polymers
is one of the businesses of Celanese Corporation. Ticona produces and
markets a broad range of engineering polymers.
Improved Processing Window of Topas 8007F-400 Provides Ability to
Form Films Practically Free of Gels
The new Topas 8007F-400 is an excellent choice for multilayer films
in which it may be used in discrete or COC-rich layers. In blown films,
it can be used in applications such as pouches, flow-pack, lidding and
twist wrap.
“Our new grade is a next-generation COC that has a much broader processing
window than prior grades,” says Bernd Sparenberg, Global Marketing Manager,
Topas Packaging, “so processors can run it on their standard extrusion
lines without any equipment modification.
“It runs well across a wide range of blown film technologies, including
on more challenging lines that involve small-scale extruders or extruders
with grooved feed zones. In all cases, it has significantly improved
COC film quality and robustness. Anyone looking for a film with an upscale
look and feel should consider this Topas COC grade given its ability
to deliver clarity, moisture barrier and stiffness at an attractive
price.”
One of the first companies to make use of this second-generation Topas
resin in blown films is Nordenia in Gronau, Germany. According
to Matthias Perick at Nordenia, “the wider processing window of the
new Topas grade was a key factor for the successful scale-up on our
blown-film equipment.”
Topas 8007F-400 is a clear cycloolefin copolymer that adheres well to
polyolefins, especially linear low density polyethylene, can be metallized
and colored easily, and has an inherent moisture barrier that can extend
product shelf life. It also has good thermoforming characteristics,
a modulus of 2,500 MPa and a glass transition temperature of 80°C.
When used in a multilayer blown film for twist wrap applications, it
provides excellent stiffness, twist retention and dead fold. Such films
match the performance and cost of traditional twist wrap materials,
yet offer many advantages. Unlike Cellophane, they do not need a moisture
barrier coating and offer overall cost benefits. Compared to polyvinyl
chloride, they stretch less in wrapping, do not yellow at the twist,
pose no envi-ronmental issues, and lack a plasticizer. And, versus oriented
high-density polyethylene, they have better dead fold, cut easier, and
do not require changes in wrapping equipment.
Topaz COC for blister packaging applications |

Topas COC complies with U.S. and EU food contact regulations. It is
used in many types of packaging, including flexible films for food,
pharmaceutical blisters, medical overwrap, shrink film, and medical
bottles, vials and syringes.
