Triple Bubble: Revolutionizing PVDC Shrink Bags for the Food Packaging Industry

Kuhne GmbH

KUHNE Anlagenbau's Triple Bubble® technology is setting a new standard in the production of PVDC shrink bags, providing an innovative solution for the food packaging industry. This cutting-edge process uses a unique three-step biaxial orientation technique that incorporates rapid vacuum cooling, simultaneous orientation, and thermo-fixation. The result is a film with exceptional mechanical strength, superior transparency, and outstanding barrier performance, all contributing to the optimal preservation of perishable food products.

Key Advantages of Triple Bubble® Technology

  • Outstanding Oxygen and Moisture Barrier: PVDC is known for its superior barrier properties, making it an ideal material for packaging perishable food items such as meats, cheeses, and other sensitive products. The ability to protect against oxygen and moisture extends shelf life, maintaining product quality and freshness for longer periods.
  • Reduced Film Thickness: The biaxial orientation process allows for the production of thinner films without sacrificing strength or durability. This reduction in thickness not only helps conserve material but also enhances the overall efficiency of packaging operations. Manufacturers benefit from reduced material costs while maintaining the structural integrity of the packaging.
  • Controlled Shrink Properties: Triple Bubble® technology ensures precise shrinkage of the film, allowing for a snug and controlled fit around the product. This enhances the visual presentation of the packaged items while minimizing excess packaging material. The result is an attractive product with reduced packaging waste, which is both economically and environmentally beneficial.
  • A Crosslinking-Free Solution: Thanks to an outer layer of PET, Triple Bubble® technology can produce high-performance PVDC shrink bags without the need for crosslinking. This PET layer not only provides the necessary heat resistance for efficient packaging but also enhances the overall mechanical strength, transparency, and processability of the film. By eliminating crosslinking, manufacturers can improve production efficiency, making Triple Bubble® an innovative choice for high-barrier shrink packaging.
  • Versatility in Production: One of the standout features of Triple Bubble® technology is its adaptability. The production line can be designed to manufacture multiple types of films on the same machine. It can produce Bone Guard films (PA/EVOH-based), EVOH barrier films for red meat, and PVDC films for red meat, all in one versatile production system. This multi-functional capability offers manufacturers flexibility and efficiency, enabling them to meet the diverse demands of the food packaging market.

The ability to produce different films on a single line reduces the need for additional machinery, saving space and investment costs. It also simplifies the production process, making it easier for companies to switch between different types of films as needed without downtime or major adjustments to the line.

The Future of Sustainable Food Packaging

KUHNE Anlagenbau’s commitment to innovation in food packaging is embodied in Triple Bubble® technology, which offers manufacturers a powerful tool to meet the growing demand for sustainable and high-performance packaging. As the industry continues to prioritize sustainability, Triple Bubble® enables manufacturers to reduce material usage while maintaining superior product protection, all without compromising on performance.

This breakthrough technology is also part of KUHNE Anlagenbau’s ongoing efforts to meet the needs of a rapidly changing market. As consumer demands for eco-friendly and effective packaging solutions increase, Triple Bubble® provides a forward-thinking solution that blends sustainability with high-quality performance. By reducing the environmental impact of packaging while ensuring product safety and presentation, Triple Bubble® technology is a key player in the future of food packaging.
