QUALITy and Safety with KTP


Did you know that plastic can change its properties when exposed to different temperatures? Plastic becomes hard and brittle at low temperatures and softer at high temperatures. The material mix plays an important role in the development of the containers. The finished container can only withstand the stresses and strains of everyday life if the assigned raw material has the desired properties and is processed accordingly.

We want our containers to function perfectly even at extreme temperatures. Therefore we test them under extreme conditions.

1. Raw Material Check

Before our raw materials go into production, they are subjected to numerous checks. For this purpose we have our own test laboratory, in which we can carry out a large number of different tests. This is the only way we can guarantee the consistently high quality of our products.

The material is tested 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)

Extreme temperatures

The Box Compression Test (BCT) determines the maximum load for our containers.

Preparation in the climate chamber: As temperatures rise, plastic becomes softer and softer. In order to obtain a meaningful surcharge value that is still valid in the storage area in the middle of summer, we heat our containers at 50°C for over 24 hours before testing.

The goal of this test ist is to check the payload capacity and stacking load capacity of our tanks and thus determine a permissible total load. Put simply, this means: how much can I load onto a container without it losing stability?

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. 

This means for you: You can rely on us and our containers!

3. Payload test (Block Storage and High rack)

Our 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. They are designed to protect the packaged goods at all times – both in storage and during transport.

Therefore, we do not only determine static values, but also carry out transport simulations. For example, we use a vibratory plate to simulate the transport of our containers on the truck. In this way we test the behavior under dynamic load.

5. Collision test

“From practice – for practice” has always been our motto. We know that our containers have to withstand a lot in everyday life.

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.

In order to avoid major container damage, we are happy to provide our customers with handling recommendations and training documents.
