New era of an innovative technology
The palletless despatch unit – now a choice between:
STRETCH- or SHRINK-wrapped !
It started with a visionary idea - eliminating
the transport pallet by using the goods
themselves as the load platform – the idea
of the self-supporting despatch unit, robustly
braced within a sealed enclosure of shrink
film. Möllers engineers developed the
reverse hood shrink system, and brought the
new technology to market.
The reverse hood shrink wrap load has
proved its worth in countless installations in
countries all around the world, proving itself
superior to conventional pallet loading.
because the pallet has disadvantages – high
cost, space requirements, no protection for
the cargo.
There was still one unfulfilled wish –
a challenge which Möllers has successfully
met with the palletless reverse hood
stretch-wrapped package, a robust load unit
with decisive new economic advantages.

Eliminating pallet costs is a major saving, but not the only one:
The palletless reverse hood package has multiple
benefits – for both consignor and consignee
The transport pallet has undoubtedly become
an indispensable element in rationalizing the
supply chain and distributing goods efficiently.
But the pallet is a costly logistics tool. Whether
they are disposable pallets or a reusable ones,
pooled pallets or your own, the procurement
costs are high. Then there are significant costs
for transporting and
storing empty pallets.
Inventory managment
and pallet repairs
involve additional
cost, which is often
significant.
The functionality of pallets is also limited in extent;
when pallet loads have to be ruggedized for
transport and protected against the elements,
additional means such as stretch and shrink
hoods have to be used. They also reduce the
effective payload by their own weight and volume.
The palletless reverse hood despatch unit is the
superior alternative in
many applications, with
advantages extending
well beyond substantial
cost savings.

New advantages of the
palletless stretch-wrapped load
The energy-saving palletless stretch-wrapped
load, produced without the application of
heat, is the ultimate in reverse hood
packaging technology development.
The highly stretchable Hi-Expander and
Ultrastretch films provide high strength for
the self-supporting packages. The reverse
hood stretch-wrapped package combines
the functions of wrapping and protecting
cargo. This also includes protection against
moisture ingress, contamination and theft.

Step 3: Wrap inner hood
Step 2: Place the base
Step 5: Wrap reverse hood

Load pressing
and turning station
Step 4: Upturn load
onto its base
The base film applicator, automatic stretch hooder and
load turning station form the basic unit of the line
The plant technology is mature and reliable,
with the HSA-Vario at its heart: The gusseted
tubular film is supplied from a reel and
reefed onto the four nested stretch fingers,
sealed to a hood along the required length,
separated from the tubular film, then stretched to the wrapping width, and drawn
over the stack covered with the base films.
When the load has been turned, the reverse
hood is wrapped in the same way.
The function of the base films is to carry the
weight of the package contents and to
protect with their high break through strength
the package base.
The base film applicator (left) covers the top layer of the
stack with the base strengthening films. The load
pressing and turning station grips the cargo stack between two conveyor belts, and turns it through180° onto
its base

... optimized for minimum film consumption
... made of environment-friendly recyclable material
Flexible in use, secure investment
Reverse hood stretch packaging lines can handle
loads of the most diverse types and formats.
The basic stretch packaging line PSH-1 is equipped with one automatic
stretch wrapping machine, with a throughput of up to 40 units per hour
Reverse hood stretch packaging lines can also
be used to produce normal unsecured pallet
loads and stretch hood pallet loads.
The range includes units with a throughput
capacity of 40 to 100 loads per hour.
This flexibility in use and the cost advantages of the
palletless stretch load makes acquiring a reverse
hood stretch line a well founded, future-proof investment
that soon pays for itself. Beside the conveyors and
the automatic palletizers needed to stack the product,
the basic palletless packaging configuration
comprises just three machine units: the HSA automatic
transverse stretch hooder, the film base applicator,
and the load pressing and turning station.

With more than 200 Möllers reverse hood
shrink-wrapping lines installed and millions
of palletless packages moving securely by
road, rail and sea – the palletless shrinkwrapped load has been making history for

By combining various film thicknesses and load
cover formats with full-size or shortened reverse
hoods, with a light cover sheet or with reinforced
base, the system can flexibly adapt to different
load weights and load stresses, whilst minimizing
film consumption.
Möllers reverse hood shrink-wrapping machines
can produce normal pallet loads with or without
shrink hood alternately, as well as palletless
shrink-wrapped loads.
30 years of perfecting the technology
Since its introduction, the Möllers reverse hood
shrink-wrapping process has always been marked by
significant pioneering advances.

compact machine for film wrapping and shrinking.
Controlled lamination of inner and reverse hood:
Significantly strengthens the load cover

Security shrink frame: Satisfies the most rigorous
safety standards of the chemicals industry.
Package designs with reinforced bases
Energy consumption: Significantly reduced.
This history of pioneering development makes the
palletless shrink-wrapped load one of the two highgrade options in the Möllers reverse hood system,
alongside the palletless stretch-wrapped load – two
technology options to choose from depending on the
criteria of your application.

Warehousing free of charge:
Reverse hood packages can be stored outdoors
Open-air storage for reverse hooded loads is variable
in size, pattern and position, and rapidly available as
required
The product is sealed tight in reverse hood
loads, excluding moisture. This eliminates the
harmful effect of water and atmospheric
humidity. This functionality soon earned the
reverse hood wrapped load a second role,
enabling product to be stored in the open.
A flat surface is sufficient; there is no need to
construct a storage building. This technique
has been used in cement works for example
to rapidly create additional storage
capacity with negligible additional expense.
Storing bagged cement in the open through
the winter unharmed has convinced even
sceptics of this additional benefit of the
palletless reverse hood load unit.
Protecting product from dirt and contamination is another function of the reverse hood
load; the sealed load also provides
protection against pilferage. Producers using
palletless reverse hood wrapping can
leverage this welcome user benefit of outdoor
storage as a marketing tool.
Reverse hooded loads with contents resistant to pressure
can be stacked two and more high, providing extensive
storage capacity

Speedy loading of trucks and railcars:
Reverse hood unit loads get moving
Reverse-hood packages are resistant to the rigours of
handling and transport. The tough film cover robustly
encloses the goods, retains the shape of the load,
and resists loading and unloading stresses. The
tightly sealed unit loads thus provide a further
advantage of this unique type of packaging: reverse
hooded loads can be transported on open vehicles,
since they are weather resistant. Open loading
platforms of trucks and railcars are faster to access;
many users have been pleased to find the new
despatch units yield significantly reduced loading
and unloading times.
Open vehicles are well suited to transporting reversehooded packages, and ease of access speeds up loading with forklifts and cranes. Loading from just one
side of the vehicle, with the forklift taking two loads at
a time, makes for especially rapid loading

Reduced loading times cuts anchorage charges:
Reverse hood packages get
sea freight going
Reverse hood shrink-wrapped loads have
proved the ideal form of sea freight.
Compared to loading loose bags in sling
hoists, they can achieve many times the
loading and unloading rate with fully
mechanized handling, thanks to their
greater volume, precise, stowable shape
with high stack pressure resistance. Reduced
loading times also cut port turnaround times
and demurrage charges. Reverse-hood
packages increase the economic efficiency
of sea freight – not least because they
eliminate the danger of bags bursting and
the consequent clearup time.
Reverse hood loads lend themselves well to stevedoring. They can be handled
by crane using C hooks, double C hooks and shackle harnesses, and also in
belt slings, supporting cooperation between forklifts and cranes

Even after long and arduous journeys:
Reverse hood packages arrive in good shape
Sea voyages are not always gentle. But a well
stowed cargo should be able to withstand rough
seas. Reverse-hood packages satisfy this requirement,
with all the features needed to arrive safe and sound
– regardless of how often they are handled, the
means of transport and the distances involved.
Economical
and environment-friendly
Changing climatic conditions – cold and heat – have
no significant effect on the transport and storage
characteristics of the unit loads. Transport and
handling with no loss of product and without
pollution provide economic and ecological benefits,
which the palletless reverse-hood package combines
with the use of pollutant-free recyclable packaging
material.
After thousands of sea miles, the goods arrive
at their port of destination in good shape,
ready to be transhipped for onward transport,
or to be stored temporarily outdoors
