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

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.
