Washing
The washing instructions below apply to the cleaning of all CurTec
packaging products that are made of polyethylene and
polypropylene:
Best results will be achieved with a washing installation that is
equipped with spray nozzles or a so-called Ultra-Sonic installation.
Best qualified detergent is a low-foaming alkaline substance with
a PH-value of 10 to 12 (solvents.)
The recommended temperature of the washing water lies
between 40°C and 50°C.
The temperature of the rinsing water can only be up to 65°C.
Washing at maximum temperature can only take up to 35 seconds
and rinsing at maximum temperature only up to 20 seconds. It
prevents the plastic from warming up and shrinking.
Increased drying of products can be effected by means of applying
cold air. If warm air will be used the drying can only last up to 30
seconds at a maximum temperature of 65°C.
The blowing and drying part of the installation needs to be
adjusted to the product, so those difficult spots of the kegs can
also be dried.
For specific technical information CurTec would like to refer to the
various suppliers of washing installations.
Attention! Check the thermostat and programmed times of your
equipment regularly.

Kiuso manual 2020-7
01 Close
The UN marking on a Kiuso is only valid if the
following closing instruction is applied.
Kiuso has a unique closing concept: press down the lid to close,
tear off the sealing strip and turn to open. After the sealing strips
have been removed, the container can be re-closed by screwing
on the lid.
Note: Kiuso has been designed for mechanically assisted closure.
CurTec does not recommend pressing down the lid manually.
1. Put the lid on the container. Make sure the loops from the tear-
off sealing strip are positioned above the handgrips
2. Slide the container into the closing machine until it reaches the
rubber stops.
3. Press both red buttons at the same time. The rubber stamp will
press down the lid until it snaps onto the container.

Kiuso manual 2020-7
4. Remove the closed container from the machine.
5. The container is properly closed when the tamper evident tear-
off strip touches the container rim.
Note: Kiuso is also suitable for full automatic closure. CurTec can
advise on the purchase of both semi and full automatic closure
solutions. Contact us for more information.

02 Open/ Re-close
The UN marking on Kiuso is only valid if the
following closing instruction is applied.
Kiuso has a unique closing concept: press down the lid to close,
tear off the sealing strip and turn to open. After the sealing strips
have been removed, the container can be re-closed by screwing
on the lid.
1. Remove the tamper evident strips one by one.
2. Release any pressure inside the container by briefly lifting the
lid at the height of the studs.
3. Use your thumbs to turn the lid. Turn the lid at least 180°, and
then lift the lid.

Kiuso manual 2020-7
4. To re-close, put the lid on the container as shown and turn it at
least 180° until the lid catches on the container rim.
Attention! A leak tight closure can no longer be obtained after the
sealing strips have been removed

Kiuso manual 2020-7
03 Use
Filling
The temperature of the content cannot exceed 70°C. The content
has to cool down to 30°C before the container can be closed. The
drum can be closed according to instruction 1.
Lifting
Kiuso can be easily lifted and moved both mechanically and
manually by using the handgrips on the container.
Attention! Please consider the HSE regulations regarding weight
and frequency restrictions for lifting
Emptying
The packaging can be opened according to instruction 2. Use the
rim and the bottom to tilt the container and pour the contents.
Freezing
Kiuso is made of plastic which is resistant to a minimum
temperature of -18°C. As of -5°C, shock load on the containers
should be avoided.
Attention! The volume of containers filled with water-based
contents can increase by 10%. The chances that containers will
distort is real and it will reduce the stability of a container stack on
a pallet. Please maintain a maximum filling level of 90% and test
the stability of a pallet stacking.

Kiuso manual 2020-7
Air transport
During air transport, the pressure drops inside a plane’s cargo
hold, which causes air inside a package wanting to escape. After
landing, normal atmospheric pressure prevails again which,
depending on the amount of escaped air*, can cause the drum
wall to cave in.
CurTec packaging has not been designed to compensate pressure
differences. The construction is such that a correctly closed
packaging alllows air to escape relatively fast, but does not allow it
to return easily.
Since CurTec has no influence on the use of its packaging by end
users, they advise to test each transport mode.
It remains the responsibility of end users to verify whether a
package and content comply with relevant transport regulations.
CurTec refers to the regulations mentioned in the UN certificates.
* The quantity depends on the content type (the shape and air between) and the
filling degree/ level

04 Static load
When stacking containers for storage in e.g. a warehouse or cold
store, it is important to know what the maximum load on the
lowest container in a stack can be.
The stacking load depends strongly on: the weight of a container,
the number of containers to be stacked, the weight of interlayers
and pallets, the ambient temperature, the duration of the load
and the surface beneath the lowest container.
The following table shows the maximum stacking load (in kg) at a
given ambient temperature, during a certain period of time, for a
container placed on a flat, closed surface or pallet.

Attention! The weights mentioned in the table have been
established after simulation and can only serve as indications.
CurTec recommends users to perform tests at all times.
The table allows you to calculate the number of containers that
can be stacked: Reduce the stacking weight mentioned with the
relevant share of the total weight of intermediate layers and
divide by the weight of the container with content. This number,
with a figure after the decimal point lower than 8, rounded down
is the total amount of containers that can be stacked on the
lowest container of a stack.

Kiuso manual 2020-7
Example
How many 20 liter Kiuso's (art. no. 4620) with a content weighing
20 kg can be stacked on a pallet at 15°C during 6 months? A layer
contains 8 containers and the total weight of intermediate layers
is 16 kg.
The relevant share of the total weight of intermediate layers is
16/8 = 2kg, so (189-2)/20 = 9.35. The number of containers that
can be stacked on the lowest container is 9.
In case of a different duration or temperature, please choose the
next appropriate row. For shorter stacking durations, the table of
instruction 5 (Dynamic load) can be of service.
Attention points
Before stacking the containers, the temperature of the contents
must be equal or lower than the ambient temperature.
The maximum stacking time is reduced considerably at
temperatures above 35°C. The stacking load in the table is at 50°C
only 75% of the last mentioned value and at 60°C only 50%.
When a stack is higher than 2.5 meters, the floor angle cannot
exceed 0.5%.
When changing transport mode, from storage to shipping or vice
versa, the lowest containers of a stack must always be placed
highest in a new stack.

Kiuso manual 2020-7
05 Dynamic load
When stacking containers for transport, it is important to know
what the maximum load on the lowest container in a stack can be.
For transport, this stacking load is called dynamic load and can be
found by dividing the admissible static load by a so-called safety
factor. These factors are:
3for air transport
2for road transport
1.8for rail transport
1.3 for maritime transport
The stacking weights mentioned in the table below are indicative
and depend on temperature and time: 5°C is the temperature for
cooled transport, 30°C is the temperature for the average
transport by road or inland waterways and 40°C is the
temperature for transport in warmer surroundings. In case of a
different duration or temperature below 40°C, please choose the
next appropriate row.

amount of containers that can be stacked on the lowest container
of a stack.

Kiuso manual 2020-7
Example
How many 20 liter Kiuso's (art.no. 4620) with a content weighing
20 kg can be transported by road at 30°C during 3 weeks? A layer
contains 8 containers and the total weight of intermediate layers
is 16 kg.
The relevant share of the total weight of intermediate layers is
16/8 = 2kg, so (173-2/2)/20 = 4.275. The number of containers
that can be stacked on the lowest container is 4.
Attention points
The maximum stacking time is reduced considerably at
temperatures above 35°C. The stacking load in the table is at 50°C
only 75% of the last mentioned value and at 60°C only 50%.
When changing transport mode, from storage to shipping or vice
versa, the lowest containers of a stack must always be placed
highest in a new stack.
The containers must be stowed professionally and fixed in such a
way that makes moving impossible.
For the use of pallets, see instruction 6 (Palletization).
For stacking containers in a warehouse, see instruction 4 (Static
load).

Kiuso manual 2020-7
06 Palletization
Palletization
Each pallet should be fitted with a solid, flat intermediate layer
prior to loading. A pallet should have an almost closed surface
fitted with planks that are no more than 5 cm/ 2 inches apart.
CurTec advises not to exceed a total stacking height of 2 meters.
In case a pallet is placed on top of another pallet, an intermediate
layer is required to enable an equal spread of the pressure. This
layer should also be solid and flat.
Filled containers are placed on a flat surface and stacked by
placing the base of the container in the counter shape of the lid.
Packing
CurTec recommends the use of a heat shrink pallet cover, which
needs to be shrunk around the pallet as well. In addition, the base
of the pallet needs to be stretched with foil as well. The
containers at the base of a stack will carry most of the load and to
avoid a collapse they cannot be deformed by overstretching the
foil or over-heating the cover.
When positioning the containers on a pallet it is important to turn
the handgrips away from the pallet corners to avoid damaging the
heat shrink pallet cover or the stretch foil.
Attention! The total load on the bottom container of a stack may
never exceed the maximum loads as indicated in the tables of
instructions 4 and 5.
Pallet handling
From a safety point of view, CurTec recommends to transport only
one pallet at a time with a fork lift truck. In order not to disturb
the stack, the forks of the truck need to be kept almost horizontal.

Kiuso manual 2020-7
Pallet schemes
CurTec advises you to respect the following quantities per layer:
1200 x 800 mm
1200 x 1000 mm
48 x 40 inches
