PRODUCTS 29 PET planet insider Vol. 12 No. 06/11 Light barrier technology ColorMatrix has unveiled a light blocking technology for PET dairy bottles, named Lactra. It is an opaque white liquid technology that ensures light-blocking at low addi- tion rates. The company says that it maintains container aesthetics and that it is suitable for both single and multilayer PET containers. It provides protection from UV and visible light at wavelengths up to 550nm, which is appropriate for extending shelf life in dairy applications such as milks, yoghurts and dairy beverages. Lactra is used at an addition rate of 6-8% for light-blocking performance equivalent to the norm of 20% for other barrier additives. ColorMatrix says that this is due to its latest generation liquid carrier system, ‘CoolRun’, whose dis- persion capability enables optimisa- tion of pigment particle size, helps to ensure stable processing, consistent colour distribution and can help mini- mise AA (acetaldehyde) levels. Aes- thetic finishes include white matt or silk finish. Lactra:eXtraShield offers even higher light blocking capabili- ties. The technologies are compat- ible with any PET grade and are fully compliant with EU and FDA food contact legislation. Amosorb SolO 2 , another ColorMatrix PET barrier tech- nology, combines oxygen scavenging with barrier properties and provides extended product protection and longer shelf-life in oxygen-sensitive beverages, particularly beers, wines and juices. Colour can be easily added, so brand owners and convert- ers can preserve product aesthetics. Amosorb SolO 2 can delay CO 2 egress by up to 30 days and protect from O 2 ingress for up to four months longer than PET with standard Amosorb. Amosorb SolO 2 can be used with any type of PET resin and is suitable for both monolayer and multilayer PET containers. www.colormatrix.com technology EnginEEring Tooling life cycle PACKAGinG FLEXIBLE SOLUTIONS RELIABLE SUPPORT Thinking of The big picTure & The minor deTails We don’t believe in delivering on one thing and not the other.

A number of structural, functional and design features con- tribute to the machines’ reliability, energy efficiency (even with partial loads), and accurate control of temperature and other operating parameters. The screw com- pressor is driven by a frequency converter and fan speed is continuously adjusted for the actual conditions of the environment and immediate demands of produc- tion. The ‘oversized’ evaporator and condenser are designed to maintain high heat transfer rates, even when working with partial loads, and thus achieve improved efficiency. An electronic expansion valve limits the pressure difference of the cool- ant fluid between input and outlet and performs controls of the fluid lamination phase, with constant adjustment of evaporation. An oil flow switch ensures that the compressor is always working under appropriate conditions. The EcoSmart’s Coefficient Of Performance (COP) figure is 9.43, compared to 4.31 for a standard chiller with screw compressor of the same size. At 50% load, EcoSmart’s COP actually rose, to over 10. The great efficiency means lower energy consumption. All EcoSmart chillers have an operator intuitive interface for setting and micropro- cessor control of the operating parameters, and can also be operated by a remote control option. www.piovan.com Barrier PeT BoTTleS
