Universal peelable lidding film for sealable trays – silver

The silver universal peelable lidding film for sealable trays offers an opaque look and a peelable seal. The film can be chosen according to aroma, moisture and light protection requirements, while it can be agreed for the sealing surfaces of several types of tray. Silver lidding can be an advantage if the top of the pack provides the surface for protection and a uniform brand identity. We define the right combination together with the actual tray material and the operation of the tray sealer.

Opaque lidding over the food

The silver film does not allow a view into the tray, so the product name, artwork and other markings take over presenting the product. The opaque top surface also plays a role in environments exposed to light, but the protection of the whole pack must be assessed together with the sides and base of the tray. We choose the aroma and moisture protection requirements for the specific food. The starting point for designing the look is thus the characteristics of the contents and the function of every surface of the packaging. The lid design can also serve consistent labelling of different dishes.

A surface compatible with several materials

A suitable application can also be chosen for the sealable surfaces of PP, PVC, PS, PE and PET-based trays, by checking the actual combination. The universal version can help plan the packaging of several types of tray with a common film, but the rim and sealing behaviour of each tray must be examined separately. The surface coating, the shape of the tray and the rim width can also influence the settings. For introduction, it is useful to carry out trial seals with a complete set of samples of the trays in regular use.

Peelable opening, verified seal

The peel design allows the lidding film to be peeled off the tray rim. Ease of opening and the seal strength needed for handling must be developed together, leaving a film area that is easy to grip. Besides the sealing settings, a clean tray rim is a basic requirement. Food residue getting onto the rim during filling must be dealt with in the workflow, and the condition of the sealed pack must be checked. A sample pack with the product shows practical opening and handling during transport.

Machine use with your own artwork

The film can be agreed for manual, semi-automatic and automatic sealing workflows, is suitable for contour cutting and can be printed with your own artwork. We match the reel design to film guidance, the tooling and the tray size. With an opaque silver surface, a legible product name and clear pack size marking are particularly important. The print must remain in the right position after contour cutting, so the artwork is best prepared to the final tooling drawing.

To agree a silver universal lidding film, we need tray samples, the details of your tray sealer and the characteristics of the product to be packed. We refine the design based on the desired opaque surface, peelable opening and custom look. At Kollár Pakk we match the solution that works with several types of tray to the actual packaging task.
