The Paperboard Group produces a fully-bleached paperboard product in an acid-free state. The following benefits are achieved:

Longer usable product life span;
Less natural deterioration as a result of ultraviolet light heat and time;
Improved performance for some converting and printing processes by allowing the use of carbonate coating fillers

Moisture Conditioning of Paper

Paper is moisture conditioned so that it will stay flat and not develop wavy or tight edges before or during printing. Wavy-edged paper can be temporarily corrected by storage in "hot room" temperatures (100º to 110ºF) for several hours before printing, or by placing strip heaters or infra-red lamps along the sides of the feeder pile near the top to warm and shrink the edges.

Die Cutting Suggestions

For the best die cutting results, Rayonier A.M. Canada G.P. - Paperboard would like to suggest the following scoring techniques:

To achieve a good crease profile, the female counter groove widths should be kept as narrow as possible. As a guide, the groove width should be equal to the sum of:
- Machine direction: 1.3 x the board thickness + the width of the scoring rule;
- Cross direction: 1.5 x the board thickness + the width of the scoring rule.
- (Note: 2 pt. scoring rule width is 0.028”)
It may be desirable, depending on the end application, to increase the female counter height by 0.002” to further enhance the crease profiles.
The height of the creasing rule is dependent on the thickness of the paperboard and the type of counter being used.

If further information is required concerning the die cutting of the Kallima® grade, please contact your Rayonier A.M. Canada G.P. - Paperboard Account Manager.

Press Ready Skids

It's a demanding business where time is money. When you've got a printing job with a tight deadline, you want to know that your skids are ready to go, so you can focus your efforts on quality. That's precisely why Kallima is available on press-ready skids in your favourite C1S and C2S stock sizes that fit most 28 and 40 in. presses.

Convenient handling

You can now use lower sheet counts to meet the needs of smaller jobs, which means lighter skids that are easier to handle.

Easy-to-remove, reusable packaging

Our packaging is also easy to remove and our smaller skids can be used to ship printed material.

Cost savings and increased productivity

By eliminating the need for re-piling, you also save time and manpower. Reducing set-up time improves your overall efficiency.

Reduced waste

Reduce waste generated during re-piling or from larger skids left unwrapped and damaged between jobs.

Skid Details

C1S and C2S stock sizes 23X35, 25x38, 26X40 and 28X40.
Maximum height of 40" on a 5" high skid.
Total height not to exceed 45" to fit most presses.
