Aroma barrier flat film / half-tube film for automatic packaging machines

The aroma barrier flat film and half-tube film for automatic packaging machines is reel packaging material where protecting the product's characteristic aroma is at the heart of the choice. It can also be agreed for machine packing of chunky or powdery fills, with a structure chosen according to the product and the process. A suitable version can be designed from a glossy transparent or matt finish, and from flat film, half-tube film and tubular film formats. The film becomes a finished pack when matched to the operation of the machine that forms the pack.

Aroma as a selection criterion

For products with a characteristic aroma, retaining aromas is one of the important tasks of packaging. We choose the material structure required for this based on the composition of the fill, the storage environment and the desired pack size. Besides the properties of the film, the seals of the finished pack also matter, so checking the seals is part of the design. It is worth stating the aroma protection requirements precisely, including whether the product will be stored next to other packs or strongly scented goods.

Flat film, half-tube or tubular film

The format of the reel material is determined by the design of the packaging machine and the planned pack shape. With flat film, the machine creates the necessary folds and seals, while with half-tube or tubular film a different starting shape is fed onto the equipment. The film width, the core and the unwinding direction must be agreed according to the machine details. The relationship between product size and the space needed for sealing is also important, so that the pack is not unnecessarily tight and the sealing surfaces can form properly. With half-tube film, the position of the folded side also influences the arrangement of the surfaces on the finished pack.

Handling chunky and powdery fills

With chunky products, size differences and edges, and with powdery products, dosing and dust release can affect packaging. The cleanliness of the sealing area must be ensured by the filling workflow, and the temperature, pressure and time must be set to suit the material. A machine trial with the actual product shows film running, how the pack forms and the quality of the seal. It is worth checking the settings at the planned speed so that packaging fits daily production.

Appearance and special processes

A glossy transparent surface puts the visibility of the product in the foreground, while a matt finish can give a different pack appearance. The choice is best judged on a filled pack, because the shape and colour of the product also shape the look. If modified atmosphere packaging is required, a complete structure suitable for it must be selected. The use of gas, the free internal space and the mechanical sensitivity of the product must be examined together, so that the packaging process genuinely relates to the specific fill.

For aroma barrier machine film, please tell us the product to be packed, the fill weight and the type of automatic machine. A sample of your current reel or a finished pack can help with sizing. Starting from these, we agree the material structure, the film format and its appearance, together with the details of the packaging process.
