For over 30 years Tecnovac has been developing the best technologies to achieve the perfect seal between tray and any type of film, as long as they are compatible. This sealing must always observe the strict quality standards established by the company.

The surfaces of the sealing plates, the operating pressures/temperatures and the containment gaskets are designed each time for each single project; thereby obtaining the best result in terms of resistance to mechanical and thermal stress caused by external factors.

In addition to the non-food macro category, often sealing-only is used with fruit and vegetables, when the product needs to be able to breathe through pre-perforated film; or when there is a opening on trays for perishables, such as “ready meals” that do not require modified atmosphere to increase the product preservation.
