Packaging viscous sauces such as ketchup, mayonnaise, and mustard in single-serving formats—stick packs or sachets—presents a number of technical challenges. Each of these products has its own unique characteristics: ketchup requires a stable viscosity during dispensing, mayonnaise requires delicate handling to avoid damaging the emulsion, and mustard combines high density with the presence of particles, making precise dispensing and hermetically sealing difficult.

Furthermore, manufacturers often face issues with product residue in the sealing area, which can lead to leaks and product loss, as well as the need for quick and efficient cleaning of equipment to maintain sanitary standards.

With over 60 years of experience in single-serving packaging, Universal Pack offers solutions that ensure consistent and high-performance production. Machines for stick packs and sachets are designed for precise dosing, clean filling, and reliable sealing, even at high speeds. They feature a hygienic design, support flexible packaging formats, and can be integrated into fully automated production lines.

Given new sustainability requirements, particularly following the entry into force of the EU Packaging and Packaging Waste Regulation (PPWR), which will be fully implemented in August 2026, Universal Pack helps manufacturers transition to more environmentally friendly packaging materials. In its in-house laboratory, the company tests new laminates with real products, verifying seal quality and package integrity to ensure consistent machine operation and minimize waste.
