Italy-based Sacmi introduces PVC-free, highly resistant seals, PMA24L, for large, twist-off metal caps used in food packaging applications that can withstand hot filling, pasteurization and sterilization at high temperatures

IMOLA, Italy , July 29, 2011 (press release) – The challenge for producers of plastics? Making seals corks and capsules entirely free of PVC, a substance that exposes certain types of food (especially oil-based) risk "contamination". Develop a new machine capable of applying these innovative seals, which no longer require the use of "curing ovens", thereby reducing not only the risk of contamination of the product but also the consumption and, ultimately, the pollution. Challenge won, for Sacmi, which since the fifties working to find technological solutions in the field of packaging for food: from the traditional "cork", through the PVC-based adhesive, to get to the compound granules, first developed without the use of PVC and which Sacmi has made a decisive contribution with respect to the provision of application solutions.

The latest is called PMA24L - acronym for "Plasmatic for Metal Sealing ring molds and capsules to 24 Large", whose prototype has been tested since mid-2010. Natural for a company already leading in the production of machines for the application of seals in the crown caps, face the problem of twist-off caps of large diameter, in practice we find in the metal lids of jars preserves, ready-made sauces, pickles, but also for children such as baby food. Fields in which to make a difference is more than ever, not only the integrity of the product from the health point of view, but also the integrity and aroma, are not always protected from PVC gaskets showed that in several cases of "give in" substances the product.

Hence the idea of ​​PMA24L, which meets the latest innovations developed by the producers of plastic materials for large caps PVC-free, a class of products which also has several problems, all of the need to produce highly resistant seals to withstand hot filling, pasteurization and sterilization temperatures above 100 degrees.

Installed and started the first prototype, in February 2011 after a long phase of reliability testing on the process, Sacmi looks to the future with optimism based explicitly on the feedback received by the customer - a German company known for packaging food - which has already ordered a second currently manufactures the machine, and already, thanks to technological jewel Made in Sacmi closures over 300 thousand a day. A significant investment repaid by the benefits, ranging, data sheet in hand, by the discontinuation of the possibility of contamination of the product to the flexibility of PVC-free materials, while the machine itself can achieve significant production speeds, equal to 1,000 seals applied to minutes.

Currently being developed to process metal capsules, the machine will, in future, be adapted to the application of seals to the plastic caps. While many satisfactions are expected from the baby food segment, with the possibility of using the technology behind the new PMA24L for the application of capsules of different materials and sizes.  Already today, the PMA is available in two versions, '"flagship", capable of processing 1,000 capsules per minute, and a smaller model, with 12 stations, which can reach 500 parts per unit time.
