Sheet splitting is the first operation in many measurement methods used to characterize sheet structure and properties. Innventia has developed a splitting technique based on hot lamination of the sample between plastic sheets. This heat-seal lamination technique is applicable to all paper products and the maximum sample size is A3 (297 mm x 420mm).

 

The main advantages of heat seal lamination splitting are the excellent repeatability and the homogeneity of the thin splits we can obtain. These are two essential prerequisites when measuring local fibre orientation and layerwise formation. Other splitting techniques are available for special application.
