KhS PlaSmaxoptiMal barrier SolutionS for SenSitive productS
03
High expectations of product quality The barrier of a plastic packaging determins, for which kind of beverages, liquid food or non food a container, e.g. PET, is applicable. All essential properties for a reliable barrier to preserve product atrributes of high quality juices, nonalcoholic beverages, beer, wine or lifestyle drinks such as „functional drinks“ are obvious:
The ideal barrier must be impermeable without reaction to the external environment or between the filled product and the packaging. Gases, like oxygen (O
2) and carbon
dioxide (CO2), that can migrate through the package wall,
will invariably deteriorate the taste of the filled product and diminish its shelf life. The vitamin C content of juices will be degraded and the product’s colour will change. Carbonated beverages, particularly in small bottles, lose their carbon dioxide content. Barrier protection must also be maintained at the highest possible level for a maximum period also under harsh climatic conditions to ensure that the packaging remains suitable for sensitive beverages.
Versatile PET PET is a plastic in big demand throughout the world on account of its virtually unrivalled benefits: light weight, transparent, not susceptible to shocks, economical to trans-port and totally recycable, making it the ideal packaging solution, especially for beverages. Optimized barrier pro-perties therefore ensure that PET materials can also be used to package particularly sensitive products to maintain their quality.
A competitive price for industrial mass production is another condition that a successful and effective barrier solution must fulfil in order to prevail on the market. At the same time perfect barrier properties must not impair the ability to recycle PET packaging on a bottle-to-bottle basis.
Crystal-clear arguments for PlasmaxThe coating methods used to meet all of these stringent demands are found in the revolutionary Plasmax tech-nology ensuring optimal, high-quality and flexible barrier coating of PET containers. This silicone oxide (SiO
x) barrier
thereby gives PET bottles properties which, in the past, were the exclusive domain of glass. Moreover, this method of-fers the following decisive advantages over other barrier solutions:
Food compatible: The Plasmax glass coating is completely inert, i.e. non- reactive and therefore safe. Since there is no contact be- tween the PET and the filled product, flavour scalping is eliminated. The permeation of gases and other sub- stances, leading to the loss of vitamins and discoloura- tion, are prevented so that the quality of the filled pro- duct is retained and shelf life extended.
Crystal clear: PET bottles with a Plasmax barrier are colourless and completely transparent to make it a very attractive proposition for marketing.
Ecologically safe: Contrary to multilayer and blend packaging, Plasmax- coated PET is 100 per cent recyclable and thus environ- mentally friendly.
Flexible and light: Plasmax-coated PET packages are not susceptible to shock and significantly reduce transport costs on account of their much lower weight, making them superior to glass bottles.
Efficient: Plasmax installations are particularly efficient and score top marks in terms of Total Cost of Ownership.
Versatile: In addition to beverage applications, the innovative Plasmax technology can also be used for liquid food such as ketchup and sauces, and significantly extends their shelf life. Furthermore Plasmax barrier enhances the application range of other plastics, including biode- gradable PLA.

PICVD plasma coating on the interior surface of the PET bottle
Optimized and patented:The coating process with the Plasmax
Reliable installationThe Plasmax machine is suitable for bottle sizes ranging from 100 millilitres to approximately 1.5 litres. The coating process is always optimally adapted to product-specific requirements.
Depending on the required barrier and bottle design, the Plasmax with its 12 rotating double-coating stations achieves an output of up to 12,000 bph. Its perfor-mance can be synchronized with the up-stream and downstream units, e.g. a stretch blow molding machine and filler.
As a result of its excellent process stability, the Plasmax machine guarantees an optimal barrier layer quality. All parts are readily accessible so that maintenance times are short, ensuring maximum uptime. In this manner the Plasmax can be perfectly integrated into a packaging line for utmost operating efficiency.

Plasmax in the focus of our clients
Consistant coating processThe Plasmax machine completes the coating in several steps: Each of the vacuum chambers is loaded with bottles. A vacuum is then applied and a reaction-gas mixture is introduced that transforms the gas into an energy-rich plasma state using microwaves to complete the reaction. Silicone oxide is deposited onto the entire interior surface of the bottle with a 10 to 100 nanometre transparent, impermeable layer.
Innovative technologyThe Plasmax machine uses the patented plasma impulse chemical vapour deposition (PICVD) process to coat the interior bottle surface with an extremely thin silicone oxide (SiO
x) protective layer to prevent the migration of gases
and other substances. The PICVD method ensures that all process parameters can be optimally adapted to the given bottle shape. It is applied to produce an effective and invisible coating, yet ensures that PET bottles remain fully recyclable.
„High barrier quality and easy operation of the Plasmax system is highly appreciated by Eckes-Granini and is convincing in the daily production process.”
Mario Dechent, Director Research & Development, Eckes Granini Group GmbH
“Our employees are enthusiastic about how easily the Plasmax equipment can be operated. They quickly became familiar with the machine and are proud to be the first to commercially use Plasmax in Switzerland.”
Pius Bernhardsgrütter, Chef d‘Exploitation Eckes-Granini S.A.
“As a converter we have the possibility to offer our clients absolutly transparent PET bottles with an optimal barrier protection for products like high quality edible oil with a Plasmax coating.
In future we see various application possibilities for products needing a trans-parent barrier PET bottle.”
Masaaki Ikezawa, General Manager at the R&D Center of HOKKAI CAN, Co. Ltd, Japan
