Viewing windows can be perfectly integrated into the packaging without any loss of stability or protection. We offer open solutions or solutions with protective film.



The variety of our folding boxes

Whether standard or custom-made: we offer unusual shapes, sizes and material combinations. We can offer the perfect folding box for your product as well as high quality and extensive experience of machine compatibility.

We develop and produce your folding box either standard or custom-made.

The best sealing for your product

In order to package a product safely, the folding boxes must be sealed. The type of sealing depends on the product, the type of box, the packaging machine and whether the box is to be reopened or secured against children. Dust flaps prevent a box from being opened inadvertently.

Tuck-in tabs
The classic sealing system: easy to use, very user-friendly, resealable. Ideal for lightweight to medium-weight products. Can be combined e.g. with base feet or blocking slits.

Tuck-in base
The alternative: ideal for medium-heavy to heavy products, as the flaps interlock; resealable. A tuck-in base is cheaper than an automatic base, but more stable than tuck-in tabs

Automatic bases
The smart specialised structure: allows easy and quick set-up without interlocking, with a single movement. The automatic base provides high stability for heavy products and is particularly suitable for manual filling.
