A

ll the new MacroPack™ blown film dies feature stream-

lined material flow passages and reduced wetted surface

areas. Both features can help customers reduce purge time by

up to 50%, and widens the process window by 30 to 40%

compared to competitive designs in the field. MacroPack™ dies

have diameters of 3 to 80 inches (76 mm to 2.0 m) and can

produce films 20 to 300 microns thick, in constructions of up to

24 layers depending on the applications.

The MacroPack-TP die is designed to have three times less bolts

than competitive dies of similar sizes. It is easy to clean and

maintain. It is often used with double-bubble technology but

can also be used for regular blown film of smaller diameter

tubes from 3 to 11 layers.

The MacroPack-CP die is designed for mainly polyolefins appli-

cations with reduced wetted surface area for quick material

changeover. It is available in diameters from 8 to 40 inches

(200 mm to 1.0 m) and produces films of up to five layers. The

innovative design which eliminates the use of a traditional

feedblock minimizes pressure drops in the die. This broadens

the process window of the die, as well as shortening the purge

time. Compared to competitive dies of similar designs, the

MacroPack-CP die reduces pressure drops by about 20%.

Macro’s MPC die features a tapered mandrel, and is the only

die in the field to have a self-centering assembly; this is crucial

especially in large diameter dies to prevent non-concentric bub-

ble shape. The special design uses up to half the bolts of com-

peting dies of the same sizes for ease of maintenance. The pro-

prietary design features a large area in the center that is not

available in the traditional stackable or the concentric dies. This

allows an optimal air exchange for high-throughput internal

bubble cooling (IBC) applications as well as large diameter bub-

bles such as in the agriculture and geomembrane applications.

This die is available up to 80 inches (2.0 m) in die diameter and

produces films of up to 11 layers.

MacroPack-FP coextrusion die not only has flow mixing chan-

nels to improve temperature uniformity in the die, but it also

has round channeled flow passages to improve purge time and

melt quality. This die is designed especially for running barrier

materials such as EVOH, Nylon, PVdC and PETg. Due to the

special features of this design, the transition time between Ny-

lon and PE can be as short as 15 to 20 min. In other competitive

dies, the comparative purge time can be from 45 min to 12

hours. This die can also be used in special applications contain-

ing up to 24 layers.

Flexible packaging is a growing market in Asia.

Michael Fischer, CEO Asia Pacific at Windmöller &

Hölscher, talks about the importance of the Asian

market, the trends in the industry and the innova-

tions shown at Chinaplas 2016.

Mr. Fischer, Chinaplas 2016 is coming up – how is the mar-

ket for flexible packaging in Asia-Pacific developing?

Rising expectation on quality, productivity and sustainability

gave a boost to the already growing market of flexible pakkag-

ing. More and more rigid packaging solutions like glass bottles

are being replaced by flexible ones, always considering environ-

mental friendly raw materials to be used. PVC products were

replaced by PP and HDPE. These developments fueled the

growing importance of the flexible packaging market.

Which technological trends where especially important

during the last years?

There are a few important developments, especially driven by
