Barrier Coatings 101
Plastic 101s: Session 3
Monday, October 7, 2024
3:00 p.m. to 3:55 p.m.
Presentation Description:
The French company ISYTECH, specialized in plasma applications, has developed a new Fluorine-free plasma coating process. ISYTECH was acquired by the Delta Engineering Group in 2022, after Delta Engineering and ISYTECH had already been collaborating intensively for 5 years, developing a range of plasma coating machines together. Today, they have a range of plasma coating machines for 6.76 fl. oz. (200 ml) HDPE and PET bottles up to 66 gallon (250 L) tight-head plastic drums.
During the presentation at ABC 2024, Danny De Bruyn – Owner and Business Development Director at Delta Engineering Group – will explain the current and planned PFAS regulations in the European Union (by ECHA), which are among the strictest ones worldwide. Moreover, he will illustrate that ISYTECH’s current plasma process already complies with all current and proposed future PFAS regulations. Trials with plasma coated 5 L (ca. 1.32 gallon) bottles of 200 g (ca. 7.055 oz), where the hydrofluoroolefin refrigerant R1234 was used in the gas mixture, showed that the concentration of all restricted PFAS molecules was equal to 1.5 ppb, so far below ECHA’s limit of 25 ppb. The total amount of Fluorine, measured using the combustion method, of the tested bottles equalled to 48 ppm, which is below ECHA’s proposed limit of 50 ppm for the future PFAS regulation.
Even though ISYTECH’s current plasma coating process already complies, they have developed a new 100 % PFAS-free process, which completely eliminates the use of Fluorine, making their plasma coating technology a future-proof solution. Danny De Bruyn will explain the new process, the chemistry, results, comparisons with fluorination, which is of interest to the North American market.

B2T: A Unique Use of Blow Molding to Produce Tubes
Session 1B: Energy Saving in Blow Molding
Tuesday, October 8, 2024
2:05 to 2:35 p.m.
(see full conference schedule)
Presentation Description:
During this presentation, Danny De Bruyn will explain the concept and advantages of Delta Engineering’s new, patented Bottle-to-Tube process, which allows you to transform blow molded bottles into squeeze tubes made of PET instead of the traditional PP.
The standout feature of the new tube is that it is made by injection stretch-blow molding (ISBM) on single-step Nissei ASB machines, rather than extrusion. The usual multistep process involves coextrusion or laminating to make a cylinder, which is cut off and fitted with an injection molded shoulder by molding or bonding. With Delta Engineering’s new process, however, oval-shaped blow molded bottles are transformed into tubes by clipping and welding the base.
A sneak peek into the benefits: This innovation opens up a new market for blow molding companies and their bottle filling customers, offering significant advantages over traditional PP tubes. Most interesting to packagers is that the new tubes can be filled just like regular bottles, which allows filling to a higher level than with standard tubes, resulting in 30% less plastic being used for the same volume of content compared to conventional tubes. Another advantage is that PET tubes can be recycled 100% in the current recycling flows, as opposed to laminated tubes. The PET tubes can also be plasma coated for enhanced oxygen barrier properties, making them an attractive and sustainable solution for packaging needs. Moreover, the PET tubes are easy to print and allow for new decorating options through embossing, not available on extruded tubes. Another advantage of PET over PP is that the tubes can be crystal clear, so you can clearly see the product on the inside: “What you see is what you get”.
Speaker Biography:
Danny De Bruyn graduated as an Electronics Engineer specializing in Telecommunications. In 1992, he founded Delta Engineering together with Rudy Lemeire. Delta Engineering is headquartered in Belgium and specializes in downstream solutions for the bottle blow molding industry.
Over the years, Danny used his expertise to extend Delta Engineering’s product range and to expand the company geographically, while venturing into new markets.
