Why is PET the best choice for packaging water?
GD: It offers transparency, low cost, good bottle characteristics for a very low weight, versatility, recyclability and a high production output.
Is there a high level of demand for PET at the moment?
GD: Yes, quite large.
Describe the range of PET services that you offer the bottled water industry.
GD: Sipa offers PET container design and development for industrial applications through 3D modelling, FEM analysis, pilot production and full testing (filling, packing, storage and distribution); engineering of production, filling and packaging, tailored to the specific customer needs and logistical requirements; and the design, manufacture and supply of a complete range of PET preform and bottle production systems (single-stage and two-stage) for the widest output range (from 1,000 bph up to 50,000 bph).
We also design, manufacture and supply a large range of filling equipment in standard and dual or three-bloc configurations, and packaging equipment (conveyors, packers and palletisers).
What are the latest technical developments in PET bottles for water, and how are they broadening design possibilities for bottled water manufacturers?
GD: In our opinion, PET is a superb resin which, in collaboration with injection and blow-molding technology, allows for the creation of almost any design. The design must also comply with specific consumer habits, marketing requirements, logistical and ambient conditions, existing industrial production and distribution systems.
Our job is to identify the limits set by the specific local circumstances and develop the water packaging that best suits the product at the lowest possible costs.
How is your company addressing environmental issues?
GD: Bottle lightweighting and energy cost reduction are the primary ways in which the environmental impact of bottling water can be reduced. We have always been at the forefront of bottle lightweighting, and our injection and blow-molding systems benefit from the latest developments.
What does the future hold for PET as a packaging material for water?
GD: It’s definitely the best resin to produce rigid containers at the lightest weights and lowest energy consumption. It also allows for the production of any type of container and is easily and fully recyclable. We don’t see any other material with such characteristics emerging in the near future.
