Henkel has
extended its Technomelt EM range and presents the Technomelt EM 132-22. The PSA
range (Pressure Sensitive Adhesives) offers high-performance adhesives for PET
and can labeling.
Technomelt EM
132-22 is a rubber-based labeling hotmelt, which is characterized by a low
viscosity and a low application temperature. The hotmelt adhesive already shows
very good bonding strength at an application temperature of only 120 degree
Celsius. This is 15 degrees Celsius lower than conventional hotmelts used for
this application. The low application temperature results in significant energy
savings and a reduced risk of cracking of the adhesive. The benefits are that
the machine has to be cleaned and maintained less often and the production
efficiency is improved. Furthermore the stress on the processed material, like
the label, can be reduced significantly due to the lower temperature.
Despite the lower
viscosity, the EM 132-22 offers the same adhesion as its precursor, the EM 362.
The low viscosity in combination with the very strong bond of the Technomelt EM
132-22 leads to considerable adhesive consumption reductions. Also for high
speed labeling machines, the low-viscosity hotmelt guarantees a precise
adhesive application with spray system, without stringing.
A Case Study
A beverage bottler
in Italy invested in new labeling machines for PET labeling. However retailers
and consumers complained about bottles where the edge of labels came off.
Thereupon the previous adhesive was replaced by Henkel’s Technomelt EM 132-22.
The labels overcome the cold test over 48 hours at minus 5 degree Celsius as
well as the heat test over 48 hours at plus 55 degree Celsius. Technomelt EM
132-22 convinces the customer with its higher adhesion in the „Hot Tack“, as
well as with its more durable overlap bonding. This successful result is achieved
with a lower and more energy efficient application temperature of only 120
degree Celsius, 10-15 degree lower as with the former used adhesive. The
customer benefits from a reduced energy consumption as well as from significant
adhesive consumption savings around 25 percent. Furthermore the customer
appreciates the easy application of the low-viscosity adhesive. Henkel
satisfies the customer requirements and provides with the Technomelt EM 132-22
an adhesive free of smoke and odour.
