Amcor OptiPack, supplied by Amcor Flexibles Barcelona, is a high quality structure using DuPontTM Surlyn®. This cost competitive solution is perfectly suited to both the fresh and processed meat industries and is currently being used in Spain mainly for Frankfurter sausages including the Oscar Mayer brand from Campofrío.

Thanks to the use of Surlyn®, Amcor OptiPack’s main advantage is a strong secondary seal that avoids leakers and negative visual aspects that can occur with meat products with a high level of water activity. Secondary sealing is a short thermal process using steam, hot air or hot water and applied to the closed vacuum pack. The heat and strength of the vacuum creates a second seal in all the film areas of the pack where there is no product, therefore liquid or blood is prevented from flowing around the pack improving the appearance of the product by giving a “clean” view and eliminating any potential bacteria growth in the liquid. The possibilities for punctures and vacuum losses are also reduced.

In addition, Surlyn® gives the Amcor OptiPack structure glossier films than with polyethylene alternatives; complete seal integrity, even if water, brine or fat spots occur in the sealing area; low temperature seal initiation allowing higher production speeds; meat adhesion, which reduces the separation of meat juices inside the pack and helps retain the attractive ‘moulded’ pack shape and the cost effectiveness of the overall solution thanks to the greater stiffness and sealability of Surlyn® compared to polyethylene.
