The packaging of fatty powders requires high barrier properties and an extraordinary sealed seam quality. Up to now, these sensitive products have preferably been packed aroma-tight with classic PET/aluminium composite packaging materials. The tested polypropylene packaging material also offers high gas tightness in combination with a fat, oil and oxygen barrier. Additional light protection through metallization is available as an option.
A clear advantage of the mono-material: the PP mono-composite can be materially recycled and is therefore a sustainable form of product protection. By using the particularly thin packaging material with a thickness of only 60 µm, significant material savings can also be achieved.
Without compromising the shelf life, a comparable output to classical applications is achieved: During an application test with a continuously operating Vertical Form, Fill and Seal machine BVC 180, a filling quantity of 250 g and a repeat length of 300 mm, ROVEMA achieved an output of up to 100 bags per minute.
