Why is this a successful embossing technology?
 Applicable to any type of embossing pattern
 No visual variation to esthetics
 Improves finished product resistance
 Improves poor paper quality and resistance properties
 Enhance good quality paper with additional resistance, bulk and absorbency

Why is this a successful embossing technology?
It can therefore be applied on cases where:
 Same finished product needs to be obtained using a poorer quality of paper
 Better finished product needs to be obtained using the same quality of paper
 Extra features (bulk, absorbency and resistance) can be obtained

Technical Features
Based on the orientation of the point, the side angles of the engraved object vary in order to modify the impact of the engraved point on the paper. In this manner the paper resistance can be modified upon request.
Each product request needs to be properly studied to maximize effects of new technique.

Main benefits
 Current R&D initiatives to improve paper resistance are focused on paper making process
 This solution gives a different prospective on methods that can improve paper properties using Embossing.
 Initiatives to improve paper resistance can be transferred from making to converting

Suggestions/Suggested applicability
 Suitable for any embossing roll technology:
• Point to point
• Desl
• Spot
• Rubber to steel
 Suitable for Toilet, Kitchen towel and industrial products, even though effects on resistance are more appreciated on Kitchen towels

Suggestions/Suggested applicability
Possible to produce micro rollers, with higher density than the current one, to be used as a pre-embossing station to change the difference between the tensile strengths in MD with respect to CD
