In PET packaging, lightweighting a bottle is not simply a matter of reducing its weight. Achieving tangible and industrially sustainable results requires targeted intervention on preform design, bottle geometry, and material distribution, while ensuring the performance requirements of both the product and the production line are fully maintained.

This is precisely the objective of Competek's Packaging Optimization service, developed to support manufacturers and brand owners in optimizing PET bottles through an approach based on analysis, design, testing, and validation.
With over 30 years of industry experience, Competek identifies material reduction opportunities throughout the entire bottle structure, finding the optimal balance between weight, strength, processability, cost efficiency, and sustainability. The benefits are significant: reduced raw material consumption, lower production and logistics costs, optimized use of rPET, and a smaller environmental footprint for packaging.

A tangible example of this approach is Airys, the lightweight bottle developed by Competek to demonstrate how the same performance levels can be achieved using less material. Weighing just 7.27 grams, Airys is the result of an optimization process that made it possible to reduce material usage while maintaining the required standards of functionality and reliability.
Lighter bottles, lower costs, and greater sustainability, with no compromise on performance.

Less material. Same performance. Greater efficiency.

This is the philosophy that drives every optimization project developed by Competek for the future of PET packaging.
