European food contact approval for VITON FREEFLOW Z200 process aids for food packaging films

Du Pont Engineering Polymers : 24 July, 2006  (Company News)
DuPont Performance Elastomers has announced that its Viton FreeFlow Z200 fluoroelastomer process aids have been declared compliant with food contact regulations in Europe for use in finished film-type food packaging materials.
The processing additive, which uses polycaprolactone as the interfacial agent, has been granted a Regulatory Compliance Statement for Food Contact Materials in accordance with European Directive 2002/72/EC, applicable to EU Member States and to Norway and Switzerland.

This is in addition to existing compliance with US FDA Regulations under 21 CFR 177.1520 § (b), Canadian Health Protection Branch and with the Japan Hygienic Olefin and Styrene Plastics Association under Japanese Food Sanitation Law, granted earlier.

“With the addition of EU compliance, Viton FreeFlow Z200 now has food contact approval effective in the major global markets of the world. This will significantly broaden acceptability of the newest PCL-based process aid, and enable film converters to use the distinctive high temperature stability, olfactory and compatibility advantages of Viton FreeFlow Z200 in food packaging wrap products,” said Christopher Fisher, marketing manager, DuPont Performance Elastomers.

In comparison with conventional and polyethylene glycol based process aids, Viton FreeFlow Z200 offers better thermal stability at temperatures up to 300°C, minimal olfactory effects, and less interaction with other additives. The process aid can help increase film line yield and eliminate melt-fracture, leading to a film with excellent clarity, limited haze, high gloss, and robust tear and puncture resistance, all of which are highly important in the food packaging industry.

Viton FreeFlow Z200 and its sister product Viton FreeFlow Z100, represented a major breakthrough in process aid technology when they were introduced to the plastics industry in 2002. Both products have become established in many food and non-food contact applications such as trash bags, tape extrusion, wire and cable coatings where process efficiency, good visual appearance, and strength and toughness are required.
