This packaging film
is water soluble
Cortec Corp.
EcoSol® is a PVOH (polyvinyl alcohol)
film (photo) that dissolves in
water in minutes. It can be made
into bags, pouches and sachets of
many different sizes to create an
efficient delivery system for a wide
range of products, including the following:
detergents; concrete additives;
water-treatment chemicals;
agricultural treatments; and bathing
products. Packaging products in
EcoSol pouches allows precise dosing
and avoids the messiness associated
with trying to measure and
apply powder products - especially
in windy conditions. EcoSol is especially
beneficial for packaging chemicals
because it eliminates the need
for direct handling. Although EcoSol
is designed to break down in contact
with water, it can be stored for
two years if kept in dry conditions at
room temperature in the original barrier
bags. After immersion, EcoSol
dissolves in water, leaving a harmless,
non-toxic, PVOH solution and
releasing

the packaged product.
Once the solution of PVOH comes
into contact with common microorganisms,
conversion to carbon dioxide
and water takes place within
about 30 days. - Cortec Corp., St.

These films make recycling
easier for dry-food packaging
Three-layer, multi-material packaging
is common for effectively
protecting dry food from the environment,
but the combination of
materials makes this type of film difficult
to separate and therefore difficult
to recycle. The Liofol product
range offers significant benefits to
film and packaging manufacturers,
with both offline and inline coating
options (photo). Due to its excellent
oxygen-barrier properties, the
coating enables a new packaging
design using only one material. This
reduces the amount of material used
in food packaging without compromising
quality and integrity. It is also
certified recyclable by cyclos-HTP
16
and recognized by the Association
of Plastic Recyclers (APR) as meeting
the Critical Guidance Protocol for
polyethylene (PE) films and flexible
packaging. Because mono-material
packaging does not need to be separated
into different components,
the recycling quality is increased
while the effort and cost of recycling
is reduced. The oxygen barrier layer
can be applied to OPP (oriented
polypropylene) and PE films at high
machine speeds in excess of 150
to 200 m/min and a weight of less
than 1 g/m² in both flexo and gravure
printing processes, and is also
characterized by excellent transparency.
This company's cooperation
with Panverta Cakrakencana, one of
the leading film manufacturers in Indonesia,
has successfully provided a
solution to improve the oxygen barrier
performance of metallized cast
polypropylene (CPP) and aluminum
oxide coating (AIOx) films. The joint
development has ensured that these
vital oxygen-barrier properties for
dry-food packaging can be achieved
when switching from multi-material
designs to mono-material polypropylene
(PP). - Henkel Adhesive
Technologies, Dusseldorf, Germany

A packaging machine for
spouted polypropylene pouches
This packaging machine, the result
of a collaboration among three
companies (photo), enables flexible,
highly efficient in-house production
of spouted pouches in various sizes
and shapes, including the processing
of different spout types. At its
core is the high-performance SPM
50 packaging machine from SN
Maschinenbau, which works seamlessly
with mono-materials. The
polypropylene-based (and therefore
recyclable) high-performance films
for pouch production are provided by
this company while the corresponding
spouts come from Menshen. The
materials and machine settings are
perfectly aligned, achieving optimal
packaging results with maximum
tightness and burst-pressure resistance.
