MATERIALS / RECYCLING PET planet Insider Vol. 19 No. 09/19 www.petpla.net 32 At K, Chroma was exhibiting its new range of frosted PET colour concentrate additives, designed to achieve the look of glass in PET con- tainers (issue 10). According to the company, processors save up to 90% by eliminating spray-painting. In issue 11, Uhde Inventa Fischer compared its Melt to Resin (MTR) technology to the polymerisation pro- cess where Solid State Post conden- sation (SSP) is required and referred to energy efficiency of PET production by about 40%. During K, Polyone launched its OnColor liquid colourant system. It has been designed to help converters and OEMs reduce costs and eliminate waste by optimising colourant use and handling (issue 12). 2011 In a case study presented in issue 7+8, Colormatrix pointed out how the implementation of their UV protection Ultimate UV390 addresses issues of costs or visual impact. At Brau Beviale, Repi was present with their Remap Liquid Colours with a broad range of colour shades and effects, and the Remap Additives for protection of packaging content (issue 11). 2012 Artenius FastFlow+ was intro- duced in issue 4. The new material was stated to capture the heat energy of the blowing process more effi- ciently, leading to energy savings of up to 20% compared to standard PET resins. Americhem added a PCR renewal additive to its range, masking yellow- ness and improving the L-value (issue 5). The cylindrical pellets have been introduced at NPE. Issue 6 highlighted Coca-Cola’s extended range and collaboration of PlantBottle packaging, made from 30% plant-based MEG and 70% PTA. The company underlined its aim to use PlantBottle packaging the compa- ny’s entire virgin PET supply by 2020. Artenius had developed a new PET resin that combines virgin PET and PCR PET as feedstock in the po- lymer production process. The result was an energy-efficient food-safe resin called Artenius Unique (issue 7+8). To increase the viscosity, the mate- rial undergoes a polycondesation melt phase, completing the removal of any contamination which might be present. 2013 Novapet had pioneered the devel- opment and delivery of solutions in PET resins and concentrates for long life dairy packaging, as we reported in issue 1+2. This includes besides the “Dairy” resins also DCU concentrates for opaque bottles and the Luz range of concentrates for transparent or translucent PET bottles. During our Editour through Russia, we visited the resin producer Senege, part of Europlast Group. Back then, they were discussing an alternative to oil-based PET and were looking into the possibilities of bio- PET (issue 3). In issue 5 we reported about what we learned at the PET 2013 Confer- ence in Moscow where a shortage of feedstock (both therephthalic acid and MEG) in the Russian PET market concerned the sector. Phoenix Technologies was launch- ing LNO w resin, a new food-grade, melt-extruded rPET pellet (issue 6). The company stated that it could be used at levels up to 100%, or blended with virgin PET. Joncryl ADR is an additive intro- duced by BASF Plastics Additives at K. It was claimed to help recyclates to achieve high performance character- istics, superior even to virgin prod- ucts. This is possible as the molecular chains produced can even be longer after adding the additive (issue 10). 2014 Catalytic Technologies Ltd (CTL) had developed a new titanium catalyst technology which eliminates the use of the heavy metal catalyst antimony oxide in PET production. The new technology has been tested by major industry players around the world. The company has announced the ambitious business target of taking over 50% of the PET resin and sheet market within the next five years, as we reported in issue 5. Acetaldehyde (AA) can affect the taste and smell of carbonated and still mineral waters. In issue 8, we were comparing two currently used AA scavenging additives, an anthra- nilamide and a polyamide-based AA system, that help reduce the nega- tive taste and odour effects of AA migration. The level of AA (ppm) was reduced by both formulations, but results demonstrated that the anthra- nilamide solution performed better, particularly at lower addition rates up to 0.15%. 2015 Sukano’s latest introduction to the PET portfolio included an impact modifier for transparent applications, reducing brittleness (issue 7+8). Also in issue 7+8, Holland Col- ours launched a new series of liquid colourants: HolcoPET. Improved pro- cessability regarding slip, retention of mechanical properties and colour distributions were claimed to be the benefits. In issue 9 we introduced NGR’s LSP process. Standing for Liquid State Polycondensation, the PET recycling process combines increased IV and decontamination properties with low energy consump- tion. IntegRex PET (iPET) was the main driver in the programme of
