High-performance packaging

Keeping contents fresh for long periods, protecting them during transport, conveying brand identity, meeting legal requirements – and doing all this in a sustainable and economical way. The trend towards humanising pets is also having an impact on nutrition. People have similar expectations for their pets’ food as they do for their own: healthy, resource-efficient – and sustainable throughout the entire supply chain.

Not only procurement and production, but also transport, packaging and the shelf life of wet and dry food play a decisive role. Individual characteristics make choosing the ideal packaging material for pet food particularly challenging: the wide variety of formats (from single portions to large feed bags), but also the requirements for shelf life, waste reduction and recyclability.

‘As Europe’s leading manufacturer of pet food packaging, we successfully pursue a material-neutral approach,’ explains Damien Maisonnial, Business Development Manager Pet Food, Mondi Consumer Flexibles. ‘Thanks to our broad portfolio of paper-based, plastic-based and hybrid materials and our variety of packaging formats, we are equipped to meet every packaging requirement, whether for dry food, wet food or treats.’

Dog snacks, wet cat food and similar products place high demands on the barrier function of the packaging material. Without a reliable barrier, the material can become greasy or moisture can penetrate and impair the shelf life of the contents. The choice of material is therefore crucial.

Packaging undergoes a real stress test during the sterilisation and pasteurisation of wet food. The food is preserved by heating – either by pasteurisation at 70 to 100 °C or by sterilisation in autoclaves at over 120 °C.

Animal feed packaging is also exposed to mechanical stress during transport, storage and everyday use. The material must therefore be sufficiently durable. In addition, there are visual elements to consider. Printing inks must be abrasion-resistant so that logos, product information and decorations remain legible even with intensive use. Furthermore, the often high humidity in storage and sales environments, as well as direct contact with grease or oils, requires durable printing processes that neither run nor fade. Machine compatibility also plays an important role. This can be ensured through close cooperation between the feed and packaging manufacturers.
