Even without a protective atmosphere, a sealed pack reliably protects against moisture, UV light, odours and mechanical stress, for high product safety and stability in transit.







For sealing, the product is placed in a formed bottom film or tray and closed with a sealing film. Heat and pressure bond the two materials firmly together, creating an airtight, hygienic pack without any protective gas.
Sealing is suitable for food, non-food and medical items, especially when no protective atmosphere is required. The pack still offers reliable protection against moisture, UV light, odours and mechanical stress.
That depends on the tray dimensions, the material, the flange geometry and the top film. Based on this information, VARIOVAC checks whether a suitable tool can be built.
Sealing is possible on all VARIOVAC thermoforming packaging machines, from the Maximus RE and the Optimus series to the Primus MP and the MedicalLine models. Among the tray sealers, the Rotarius, Linus 650 and Linus 1100 seal pre-formed trays.
Yes. Sealed packs can optionally be made resealable. They also offer plenty of design options, for example in labelling, and present your product attractively.
The sealing film is sealed either to a bottom film formed on the machine or to a pre-formed tray. VARIOVAC supplies suitable films for thermoforming packaging machines, and menu trays, MAP trays, brine trays and Euro freshness boxes for the Rotarius and Linus tray sealers.
Yes. Besides food and non-food, sealing is also used for medical items. For the automated packaging of medical sterile goods, VARIOVAC offers the Optimus MedicalLine and the Primus MedicalLine.
After sealing, cross-cutting and longitudinal cutting separate the packs from one another. Depending on the application, a guillotine, punch, circular knife, rotary shear cutter or crush knife is used. A discharge conveyor carries the packs out of the machine, and a line converger such as the Variotrack can then merge them into a single lane.
Depending on the model, sealing, vacuum, MAP (modified atmosphere packaging), skin, steam and shrink are possible. The Primus MP also supports multi-layer packaging (MLP).
