Types of cardboard
To produce our packages we use corrugated cardboard which consists of external smooth sheets of cardboard and internal waved sheets of cardboard. There are many different types of corrugated cardboard with different technical specification and usage.
Structure of cardboard
Cross-section

A - Wave height
B - Distance between waves’ peaks
We divide cardboard into five types depending on a number of waves:
2-layer cardboard
Usage:
- We use it as a protection in indoor repairs. It can protect floors in building where we paint and do other redecorations. Thanks to two layers it rests dry.
- It replaces foil and it is an ecological product. It does not have any chemical ingredients. It is a product 100% bio-degradable and is not harmful to our health and our environment.
- It can be re-used.
- It can be put directly onto packages, as inserts or as a half- product for cardboard packages.
It is most often packed into rolls with width of 160 cm and length of 10-150 lm.
