KraussMaffei Berstorff Schaumex for
perfectly tight screw caps
(Hannover, 16th May 2013) With their new Schaumex ISO-PAC foam
extrusion lines KraussMaffei Berstorff offer the perfect solution for
eco-friendly and cost-effective production of cap seals made of PE lowexpansion foam. As these seals are required for air-tight closing of
screw caps used for bottles, containers and jars, the worldwide
demand for this type of equipment is continuously rising.
Eco-friendly low-expansion foam production
The KraussMaffei Berstorff machine portfolio comprises various production
lines for physically foamed products. The Schaumex single-screw extruder
series produces sheets, film, pipes and profiles. The machines combines all
process steps in a single machine - from compounding, blowing agent
injection and incorporation up to the final cooling stage. These steps are of
decisive importance when using CO2 as environmentally compatible blowing
agent in the production of expanded products. The extruder has a
processing section of 40 L/D length with electrical heating and air-heating
systems in the compounding and mixing section to melt the plastic material
at about 200 °C and to mix in the required additives. The CO2 blowing agent
is injected through a special injection system in the central section of the
extruder barrel. The processing zone downstream from the injection point is
equipped with a fluid temperature control to cool down the melt with the
blowing agent to about 130°C.
Four extrusion lines sold to customers in Asia and Eastern Europe
“We are faced with an increasing demand for Schaumex lines at
international level. Recently, we have sold two Schaumex 120 lines with an
output rate of 210 kg/h and two Schaumex 150 extruders with a lowexpansion film production capacity of up to 320 kg per hour to customers in
Asia and Eastern Europe,” reports Matthias Reimker, project manager for

efficient outside air cooling. The cut flat sheet is cooled down on a take-off
unit with two water-cooled cooling rolls of 600 mm length and subsequently
wound up. In addition to the single-stage Schaumex process, KraussMaffei
Berstorff offers Schaumtandex solutions composed of a primary extruder for
plasticizing and homogenizing and a secondary extruder used for melt
cooling.
Physical foaming increases environmental compatibility
“Expanded sheets with a density ranging between 250 and 450 kg per cubic
meter are referred to as low-expansion foam“, explains Matthias Reimker.
“15,000 tons of PE based low-expansion foam are produced in Europe every
year.“ Considering the weight of approx. 0.4 grams of each typical seal with
2 mm thickness and a diameter of 25 mm, the production quantity after edge
trimming corresponds to about 75 million seals per day”, adds Matthias
Reimker. As this large niche market is also faced with an increasing demand
for eco-friendly solutions, today about 75% of low-expansion foam products
are produced on the basis of non-polluting physical foaming processes, and
only 25% using chemical foaming. Apart from environmental aspects, this is
also due to the fact that reaction products of chemical foaming processes
may affect odor and taste, which must be avoided in the food sector.
