Warm-up Contactless redefines
hot embossing and its benefits
for tissue manufacturers
Stefano Palazzesi, Product Manager, Körber Business Area Tissue
INTRODUCTION:
Tissue manufacturers are under unprecedented pressure. Pulp price volatility and the skilled labor shortage remain primary
concerns. However, the increased emphasis on sustainability, product differentiation, and global competition cannot be ignored. Increased
pulp prices are likely the norm for the foreseeable future. Tissue manufacturers and converters are placed squarely in the middle of the
supply-and-demand struggle. Questions about costs and profitability are inevitable.
In response, source rolls of less expensive fiber are being
used to help control costs. Hot embossing is heavily relied upon to
deliver toilet paper and paper towel rolls of increased firmness and
volume while simultaneously preserving tissue quality.
Doing so helps tissue manufacturers deliver to customer
quality expectations and remain competitive in the global
marketplace. Customers are particular about the tissue products
they use, and a shift in quality could cause dissatisfaction. Loyal
brand advocates may leave and take their dollars — and tissue
manufacturers’ margins — with them.
There are also the issues of product differentiation and
sustainability. Tissue tensile strength,
softness, and absorbency
are at the heart of
successful outcomes in these
increasingly important and competitive areas.
The challenges are many, as are the opportunities
for innovation. Finding a broad-based solution that
addresses these pain points requires advanced tissue
technologies and the expertise it takes to apply them.
The disadvantages of hot liquid embossing systems
Conventional hot embossing methods rely on hot oil or
pressurized water to heat each embossing roll in its entirety.
The piping networks needed to circulate the heating liquids are
expensive and complex, require roll modifications and excessive
downtime for installation, and can be dangerous in the event
of failure. Long heating and cooldown times and high thermal
dissipation also contribute to low overall equipment effectiveness
(OEE).

While oil and pressurized water hot embossing systems
work, they also limit the ability to efficiently respond to shifts in
market demand for certain product differentiators. As a result,
tissue manufacturers could miss opportunities and lose competitive
advantage.
Tissue manufacturers have been left to make do with liquid
hot embossing systems. However, compromise is no longer an
adequate strategy during turbulent times in the industry.
It’s an unenviable position for tissue manufacturers. It’s
also the impetus behind the embossing breakthrough developed by
Körber engineers.
