Two years ago, testing on a 10,000 jar production run marked the introduction of PROVALIN®, a compound free of PVC and plasticisers. Now more than 50 million seals are on the market.
PROVALIN is a thermoplastic elastomer which does not require any plasticisers and as a result displays extremely lowmigration characteristics.
This sealing material quickly evolved into one of the decade’s success stories involving the commercial development of an entire range of PROVALIN variants.
Long-term tests have shown that the compound is safe and complies with EU and FDA regulations.
The fact that PROVALIN is compliant with all regulations and requirements for filled contents, sealing processes, storage and seal sizes has contributed to the success story.
There are no restrictions in the filling and sealing process, including hot or cold filling or subsequent heat treatment such as pasteurisation and sterilisation.
Seal sizes 53, 63, 66, 70, 58 and 48mm are already on the market with 38, 82 and 66mm deep (jam) to follow.
The focus is on food safety with the result that risks are avoided during conversion.
In the case of filling, sealing and subsequent treatment processes, customers are given intensive support as these processes vary from one filler to another and need to be adapted individually. This also applies to optimising opening values and vacuums.
Users can depend on product tested safety supported by laboratories in Switzerland which regularly draw up independent migration reports.
The list of commercial manufacturers using packaging free of PVC and plasticisers now reads like a global Who’s Who of the food industry and more majors are in the process of having the product qualified in their countries of operation.
Product developments are also underway with brand-name producers such as Unilever, Mars, Heinz and Nestlé.
Actega DS hold the patents over the product which was developed with Feinkost Dittmann and seal manufacturer Pano.
