Multi-Cap Double seal
The demand for plastic screw closures is growing steadily as a result of the enormous growth being experienced in the
global market for PET bottles. This promising development has prompted existing producers to continuously expand
their capacity, whereas more and more new companies are also entering the market.
Bottle closures are mass-produced where keeping the costs per moulded
item as low as possible is a significant factor.
However, the factors of dimensional accuracy and quality play a very
important role, because the closure must always
provide perfect sealing and venting properties as well as an
absolutely reliable tear-off tamper evident band.
The company, Polar Plastics cc, has introduced to
the South African market a unique one piece 28mm double seal closure
for carbonated soft drinks (CSD) which in comparison to existing
closures enjoys the highest performance standards.
The Multi-Cap double seal closure is moulded on a Netstal SynErgy
injection machine that ensures permanent stable
process quality. The standard features of the machine include closed
loop process control, parrallel machine movements
that ensure high efficient production output. The extremely sturdy
machine design extends the mould life substantially,
which in turn has positive effects on part manufacturing costs.

The Multi-Cap 28 is equipped with a tamper evident band remaining

well for the user (capping equipment) and for the
