/ Corrugated cardboard: each purpose has its own materialCorrugated cardboard - basis of our litho-laminated boxes - is a resistant, light, hygienic, 100% recyclable and ultra-flexible material.
In order to better meet the expected properties of the packaging for any product, many paper weights and flute types are proposed so as to define the optimal combination in terms of protection, visual perception and environmental footprint.
To determine this optimal cardboard combination, different parameters must be taken into account:
There are different types of corrugated cardboard: single face, single wall, double wall, triple wall... Sales packages are mainly in:
Each component has a specific function:
| INSIDE LINER | Cohesion and resistance necessary for protection of the content |
| FLUTING | Elasticity needed for shock absorption, rigidity, resistance towards stacking's constraints |
| PRINTED POSTER | Support for printing |
Starch glues allow to assemble the medium with inside liner and printed poster.
Main papers used by LGR Packaging:
Printed posters: papers for printing
Inside liners and fluting: papers for corrugating
Relying on project's input data, the choice of papers will be made based on each material's aspect, weight, thickness and properties.
The flute's profile defines the level of resistance and elasticity of the packaging.
| Flute's type | C FLUTE "big" |
B FLUTE "small" |
E FLUTE "micro" |
F FLUTE "mini micro" |
G FLUTE "super mini micro" |
| Thickness (printed poster + fluting + inside liner) |
4 mm | 3 mm | 1.8 mm | 1.2 mm | 0.7 à 0.9 mm |
| Properties | Flute adapted to heavy products | Good resistance to flat crush strength | Relatively flat surface for high quality printing applications | Great price-quality ratio between E and G, lower fiber content | Flexibility, strong alternative to folding carton, printability |
The double wall fluting is a combination of different profiles: F/E, F/B, E/E, E/B, B/C, etc.
Input data and utilization for the end user must then be taken into account in order to determine the optimal combination for the box.
