We develop, build and test for you

Quality and Safety with KTP

We want to maintain our high quality and safety standards, which is why we made a conscious decision to manufacture our products exclusively at our headquarters in Saarland/Germany. Development, production and final inspection are carried out in one place.


From concept to product

At KTP, we combine 30 years of experience in the packaging industry in order to develop the optimum container system for every transported good. Our motto is „From practice, for practice“. In order to do justice to this, we involve our customers closely in the development and elaboration process of their packaging.

In direct cooperation with our project managers and developers, the best possible container system is designed according to the individual requirements of our customers. Optimum storage and transport conditions are taken into account as well as the required payload, durability and resistance of the container system to environmental influences. Special properties such as ESD protection or a tracking system as well as the material of the inner packaging are also adapted to the specific product.

Together we will find a suitable packaging solution that meets all your specific requirements.

Toolmaking department

Tailored to your container

In order to meet all product requirements for your future container, we operate our own tool shop directly at our production site in Saarland/ Germany. This shortens the necessary communication path and allows us to follow and support production in the best possible way. New configurations or necessary change requests can be communicated and implemented quickly.

The combination of product development and production also gives us the opportunity to produce prototypes and test series for our customers. In this way, the first samples can be tested and further optimisation requests from our customers can be adopted quickly and easily.

Test laboratory

For quality and safety

Just like development and production, our test laboratory is also located at our location in Saarland/ Germany. In our in-house test laboratory, we subject all raw materials and every finished product to a large number of checks in order to guarantee a consistent level of quality.

1. Raw material check
2. Stacking load
3. Payload
4. Transport simulation
5. Collision resistance

Our raw materials

LD-PE/ HD-PE / Recycling for a positive eco-balance

Plastics with a positive eco-balance – is that possible? Yes, it is!

At KTP we only use LD-PE (Low Density Polyethylene) and HD-PE (High Density Polyethylene) for the production of our reusable containers. These two raw materials both belong to the polyolefins and consist only of hydrogen and carbon. As a result, we achieve a positive eco-balance and also have a high energetic use of our raw materials. In addition, we set high standards – not only for ourselves but also for our suppliers.

Raw material controls and an intensive sorting process to exclude contamination are a matter of course for us and an integral part of our quality control. The properties of the finished products can be individually influenced by different mixing ratios of LD-PE and HD-PE, depending on the desired application. The high level of resistance to acids, lyes and other chemicals is another point in favour of these raw materials.

1. Raw material check

Before our raw materials go into production, they are subjected to tests for elasticity and purity. The scope of the tests ranges from simple descent tests to the determination of mechanical characteristic values by means of a tensile test machine to the use of a DSC device in which the thermal properties of the plastic can be determined.

2. Stacking load test (Box compression test)

The Box Compression Test (BCT) determines the maximum load for our containers. Plastic softens as temperatures rise. Therefore we store our containers in our climatic chamber at 50°C for over 24 hours before testing. In this way, we simulate storage in midsummer and at the same time obtain a meaningful surcharge value that meets all requirements.

The heated container is placed in a test press. This press exerts a continuously increasing force on the container from above until it finally breaks. The breaking load value thus indicates which weight acting from above causes the container to break. This procedure is repeated several times to determine an average value that is as exact as possible. The maximum load on our containers is calculated from this average value. Because our containers stand for quality and safety, we calculate this value taking into account a 2-fold safety.

Now squeeze the container and pull the slider down in the picture.

3. Payload test (Block storage & high rack)

KTP containers are made to be durable and robust. This is why we carry out the payload test as a long-term test. This test is equivalent to long-term storage in block storage or high rack warehouses. For this purpose, the pallets are loaded and inspected over a period of several weeks.

Over time the pallet bends more and more. These values are recorded at certain intervals until no more change can be detected. Then the maximum deflection is reached. After the loads have been removed, we can determine the irreversible deflection. From the results of this test, the permissible payload of our containers is then determined.

4. Transport simulation

We manufacture transport containers that are in use for our customers day after day to transport a wide variety of goods and products. In order to ensure consistent protection of the transported goods, we do not only determine static values for stacking load and payload, but also carry out transport simulations.

We use a vibratory plate to simulate the transport of our containers on the truck. In this way, we receive information about their behavior under dynamic loads during the test.

The top priority is always to deliver the packaged goods safely, securely and undamaged to their destination.

5. Collision test

Our products should be robust enough to withstand minor mishaps such as a collision with the forklift or a fall from a certain height. The aim of the collision test is to determine under which parameters, i.e. force and speed, the container gets damaged. For this reason, special tests are carried out for possible damage caused by handling with forklifts.

A lot of damage can be avoided by correct handling. Therefore, we offer handling instructions for our containers, which show the correct handling and reduce the occurrence of possible damage.


Tailored to your product

Once all tests have been completed, from raw material testing to loading and payload tests and transport simulations, there is nothing standing in the way of series production of your container.

Our production is state-of-the-art – manufacturing processes are continuously adapted and optimized. This ensures high-quality and speedy order processing for our customers.
