Implement sustainability in a technically sound manner.

How do you implement sustainable materials in a reliable process?

Sustainable materials are changing processes. KOCH develops machine technologies that integrate sustainability reliably into the process – for less material, better recyclability, and PPWR compliance.

From the requirement to the sustainable solution

Sustainability only works when the process runs smoothly.

Sustainable packaging is more than just a new material. What matters is that design, material, and machine fit together. Otherwise, waste, downtime, and costs increase.

KOCH combines packaging concepts and machine technology. We test materials and process parameters, ensure sealing and handling performance, and integrate the right technologies so that sustainability remains economically viable.

Film Saving

Reduced film consumption and perfectly sealed blisters.

Smart Heating

In the smart heating process, a component-specific heater introduces the heating energy in a precisely controlled manner.

Smart Forming

The software-based molding process enables a faster pressure build-up in the mold cavity.

Clever Cutting

Intelligent cutting methods ensure significant material savings.

Process Benefits

The more productive a packaging machine is, the more sustainable it is, the lower the resource consumption.

Film Saving

Reduced film consumption and perfectly sealed blisters: We achieve this goal by sealing using ultrasonic welding. This process allows for significantly narrower sealing edges. In addition, the forming and sealing materials can be identical, so the packaging can be fed directly into the recycling process without separating the components.

Process and advantages

  • Sealing using ultrasonic welding
  • Lower film consumption due to narrower sealing edges
  • Possibility of mono-material packaging for better recyclability

Smart Heating

With the patented Smart Heating process, a part-specific heater delivers the heating energy with exact dosage. This allows the material thickness at every position of the packaging to be perfectly controlled – for an overall reduced film thickness while simultaneously optimizing blister quality.

Process and Advantages

  • Digitally controlled heating station
  • Highly precise control of film distribution
  • Optimized film thickness for greater stability
  • Reduced energy consumption for heating the film
  • Less material usage due to overall reduced film thickness

Smart Forming

The software-based forming process enables a faster build-up of pressure in the mold cavity, resulting in optimized material distribution and reduced film consumption. This allows the use of thinner films, while the blisters remain stable and of the highest quality. Thanks to the increased pressure, the forming process is also faster and more productive. Temperature-controlled tools ensure good blisters from the very first cycle, and an air shower in the forming station provides optimally tempered film even when the machine stops. The process can be restarted without material loss.

Process and Advantages

  • Software-based forming process with increased forming pressure
  • Negative forming with pre-stretching of the film, positive forming with forming punch
  • Uniform pressure distribution over the entire mold surface for optimized material distribution and reduced film consumption
  • Further reduced material consumption through the use of thinner films
  • Faster forming for more blisters per minute
  • Precisely formed blisters of the highest quality – from the very first cycle, even after a machine stop

Clever Cutting

Intelligent cutting methods ensure significant material savings, especially for small products. Depending on the packaging shape, we select the appropriate method and, by optimally utilizing the machine format, ensure that very little or even no film waste is generated in the process.

Methods and Advantages

  • Longitudinal and cross cut for packaging with right-angled corners, completely without film waste and residual grids
  • Star cut: Punching out a star shape for rounded corners, then separating the packaging by longitudinal and cross cut; with minimal waste
  • Bone cut for packaging with a perfect radius, without sharp edges; no film waste in the running direction and reduced material usage due to narrower intermediate webs
  • Offset cut: The special arrangement of the cavities in the punching tool allows the webs/waste strips between the cavities to be significantly reduced

Process Benefits

The more productive a packaging machine is, the more sustainable it is, and the lower the resource consumption of energy and materials. Throughout the entire packaging process, a variety of technical features are used, which together enable overall higher machine and line availability.

Processes and Advantages

  • Targeted ejection of only individual faulty blisters or cycles
  • Film change during ongoing operation
  • Short changeover times to new formats
  • Fast batch changes “on the fly,” without stopping the machine

PPWR in Practice

Technically prepared for new requirements

The PPWR increases the pressure on recyclability, material usage, and traceability. KOCH supports you with machine technologies and process concepts that reliably handle new materials and packaging forms.

Turnkey: Sustainability as a Complete System

When concept and machine fit together, sustainability becomes predictable.

Turnkey means: sustainable packaging is not considered in isolation, but implemented as a complete system consisting of material, design, process chain, and technology. This reduces risks and makes results measurable.

Sustainability & responsibility

Pack responsibly and for the future.

With KOCH, you reduce material usage by up to 30%, use monomaterials, and achieve your ESG goals – without compromising on protection or appearance.
