Packaging food products in bags made of recyclable paper

The LEAF packaging machine from KRONEN's partner GKS Packaging B.V. was developed especially for packaging food in paper bags. Products such as whole, unpeeled potatoes, carrots, onions or similar products can be packaged in pillow or block bottom bags with carrying holes. The bag width is adjustable between 190 mm and 400 mm, and the bag length is unlimited (is 480 mm per sealing step). The packaging material is recyclable, compostable paper made of an FSC® certified mono-material that does not absorb moisture from the packaged product and maintains its rigidity and structure. 

The packaging machine construction is modular and open, making the inside of the machine easily accessible for simple cleaning and maintenance. Some components are made from recycled ocean plastic. 

The machine can also be operated with conventional packaging film.

KRONEN benefits

Intuitive operation

The machine is operated by means of iPad interfaces on both sides of the machine. The machine status is quickly visible by means of intelligent LED lighting. The packaging machine is very easy to operate without prior knowledge due to its good accessibility and clearly arranged operation. 

KRONEN benefits

Automatic detection of bag length and the end of packaging film

A light barrier can automatically detect the bag length of pre-printed paper bags. The LEAF also detects the end of the packaging film independently. 

KRONEN benefits

In-line net applicator for secure sealing of viewing windows in paper packaging

When producing bags with a viewing window, the machine can close the bags directly with a net so that no products can fall out.
