Gas barrier anti-fog lidding film for sealable PP trays

The gas barrier anti-fog lidding film for sealable PP trays combines product protection with clear presentation. Its gas barrier design can be chosen as part of vacuum or modified atmosphere tray packaging, while its anti-fog property helps keep the film transparent in moist, chilled environments. For a good result, the product, the tray, the lidding film and the seal must be designed together. This version suits tasks where both the internal atmosphere and visible food are important.

Gas barrier across the whole pack

In modified atmosphere or vacuum packaging, the lidding film is one element of the system. The tray material, the sealed rim and the packaging process used must all serve the same protective purpose. We agree the required gas protection based on the composition, processing and storage conditions of the product. We therefore examine the choice of gas barrier film together with the specific tray and machine; checking the finished pack provides feedback on the seal achieved and how well the process fits.

Visibility in humid conditions

The aim of the anti-fog design is that condensed moisture impairs the view through the transparent lid less. The packed food can thus be presented more easily even where temperature differences may cause condensation. Performance is also influenced by the moisture of the product and the filling and chilling sequence. It is worth checking the pack in the real storage and display environment, because the surface design of the film and the whole temperature process together shape its appearance.

Sealing matched to the PP rim

We choose the lidding film to suit the sealable PP surface of the tray. An accurate seal requires a clean rim and the right pressure, temperature and sealing time. The fill level must be set so that the product does not touch the sealing surface. The film can be agreed for manual, semi-automatic and automatic tray packaging workflows, with contour cutting on suitable equipment. During the trial, we check film running, seal continuity and cutting as part of the same packaging setup.

Appearance and custom print

For a clear view, the artwork must also leave enough room to present the food. When producing your own print, we match the branding and product information to the tray size, the cutting contour and the transparent area. Storage instructions for the chosen packaging process should appear on the pack in line with the specific food. It is worth examining the legibility of the print and the appearance of the anti-fog surface together on a filled, chilled sample before introduction.

For gas barrier anti-fog PP lidding film, please tell us the type of tray and machine, the product and the planned vacuum or modified atmosphere process. Knowing the filling and storage temperatures is also necessary for the discussion. On this basis we choose the film for the whole packaging system, taking product protection and presentation into account together.
