The discovery of TCA led to the suspicion that the granulate had become contaminated in some way. However, the occurrence of the contamination in granulates from different manufacturers could not be explained. The TCA and TBA found in PE coated cartons came from the PE and not from the paperboard. Finally, these substances were found in food that was packed in pouches containing PE. 

Ecovio FS Paper is also a compound of Ecoflex FS and PLA with a very high content of renewable resources. This grade was optimized for extrusion coating of paperboard. It can be processed on standard PE equipment and shows an excellent adhesion to card board and paper. The Ecovio coating forms a barrier for fat vegetable and mineral oil, liquid and aroma. Applications of choice are compostable paper cups for hot and cold drinks, freezer boxes or paper wraps for snacks. 

Two of the substances detected, pentamethyl heptene and tetramethyloctene were considered as substances known to contribute to the odour of extrusion film coatings. The fact that these substances could transfer from the film to the gas phase supported the potential for these substances to give rise to odour problems in foodstuffs. They also impregnated a filter paper with octanal and placed it in the test cell in contact with paperboard laminated to various films including PE, PP, poly(ethylene terephthalate) (PET) and aluminium/PE (Al/PE) (with PE on the outer surface). They monitored transfer of octanal across the material held at 30 °C for 8-10 hours. Transfer was most rapid through uncoated paperboard. Octanal was shown to transfer across PE film laminated to the paperboard within ten minutes. There was no transfer of octanal through PP, Al/PE and PET over ten hours.
