PVC-free closure Pano BLUESEAL
The food industry has been calling for closures with PVC-free sealing material for glass jars for many
years. Pano Verschluss GmbH is the first manufacturer to offer closures with a PVC-free seal which
are able to close the jars as securely as they could previously.
The new PVC-free sealing compound is based on thermoplastic polyolefins (TPE) which already
possess an internal plasticizer and therefore no longer need any softening additives. Materials of this
kind have been used in the crown cap sector for years. Expert analysis by the Nehring Institute in
Brunswick and the SQTS, Switzerland confirm that all relevant food regulations are being observed.
An additional plus: The new sealing compound has low migration and, compared to conventional
PVC- sealing compounds, it lowers migration potential several times over. Therefore, the migration
legislation in place since 1st May 2009 which applies to filling substances containing fat can be
observed unreservedly.
In the meantime, a variety of well-known companies from the fine food, delicatessen, and organic
sectors have been convinced of the operational capability of Pano BLUESEAL ® and have altered their
packaging in favour of this.

vacuum capping machines, the sealing behaviour (safety, N-N-distance and opening power) is
comparable to that of closures with PVC seals. The closures can be used for all filling substances and
for heat-treating up to 98 °C without counter pressure, pasteurisation without counter pressure is also
possible with an appropriate pressure control system. A sterilisation-proof version is being developed.
The material is coloured blue to distinguish it from PVC seals.
Mass production of TO 66 closures began in the first quarter of 2011 - naturally in both versions, with
and without buttons. From June 2011, production of diameters with 53 mm and 63 mm got underway,
other sizes are being prepared.
