Breathable film for packing vegetables

Breathable film for packing vegetables is a packaging material on rolls that can be tailored to the needs of fresh produce. For washed, peeled or cut vegetables and fruit, the gas permeability of the film, together with the respiration of the product, shapes the conditions inside the pack. The transparent version shows the contents, and it can be chosen as flat film, half-tube or tubular film to suit the packaging process. We start agreeing the material from the specific product and the planned storage.

The product's respiration determines the requirement

Vegetables and fruit continue to respire after packing, and the rate depends on the variety, condition and temperature of the product. Cutting or other preparation changes the requirements for the packaging. The gas permeability of the film must therefore be chosen for the specific product and fill weight. For mixes of several ingredients, it is advisable to examine the behaviour of the whole fill. The conditions that develop in the finished pack are determined jointly by the material, the free headspace and storage. Even at the same fill weight, different vegetable mixes may require different films.

Roll material on the packaging line

Flat film, half-tube and tubular film provide different starting formats for forming the pack. We match the choice to the operation of the machine, the required pack size and the dosing of the product. Besides film width, core and unwind direction, the position of the sealing bands must also be agreed. A trial shows how the product goes into the pack, how much free space remains around it and whether the seal can be formed evenly at the planned packaging rate.

Chilling, moisture and gentle handling

We link the choice of breathable film to the filling and storage temperature. Placement of wet or easily damaged produce, cleanliness of the sealing surfaces and the arrangement of the outer packaging are equally part of the task. The hygiene and chilling procedures defined for fresh produce must also be followed during packing. It is worth extending the introductory trial to the actual transport and retail conditions, so that the chosen film can be assessed along its entire path of use.

Visible fresh produce, your own branding

Through the transparent surface of the film, the colour and preparation of the vegetables or fruit can be shown. We also produce versions printed with your own artwork, where branding and product information can be adapted to the required pack format. Besides the markings, it is advisable to leave enough of a viewing window. A common design can be planned for several pack sizes, but the film properties required by the product must be agreed separately for different contents and quantities.

To choose a breathable film, please send us the name of the product or mix, its preparation, fill weight and the details of your packaging machine. Based on the planned chilling and display conditions, we will agree the material needed for gas exchange and the roll format. At Kollár Pakk we design fresh produce packaging from the combination of contents, film and workflow.
