La saldatura deve garantire l’ermeticità e la tenuta in presenza di contaminanti. La progettazione del film deve tenere conto della temperatura di saldatura e delle proprietà di hot tack che misura la forza di saldatura a caldo tra i film. Vengono progettati comunque tenendo presente il prodotto da imballare, la macchina di confezionamento, le fasi di trasporto e movimentazione dell’imballaggio. Gli strati saldanti sono disponibili in: polietilene bassa densità, polietilene metallocenico esene (C6), polietilene ottenico (C8), plastomeri C8, copolimero EVA.


The peelability function is achieved in two different ways: (1) peelability of the layers due to incompatibility (easy peel) where the added additive creates a hermetic seal but easy to open with different forces according to the customer's requests (generally from 3 -6 N / 15mm); (2) peelability due to breaking of the layers (burst peel) where the opening force is unique and characterized by a high value at the beginning which then decreases after opening. All peelables are designed based on the welding surface. They are available for: polypropylene (PP), polystyrene (PS), expanded polystyrene, polyethylene terephthalate (PET).

Suppositories and blister packs

Polyethylene film for medical packaging products such as suppositories and blister packs in the sealed package and in the original form, in compliance with the requirements of the Pharmacopoeia relating to polyolefins for medical-pharmaceutical use. Waste or recycled plastics have not been used during the manufacture of the above products.
