Mira hot fill bottles recycled pet

Recycling is the heaven and hell of PET. The vision of paradise comes from the ecological appeal and the image of purgatory stems from the advancement of polyester retrieved on the terrain of Virgin resin, already plagued by chronic global excess in your offer. Study out of the oven American consulting firm Plastic Technologies Inc. (PTI) throw more fuel on that fire to wave with the possibility of increasing, without adverse impact, the recycled content in PET bottles bottled hot (hot fill). Ron Puvak, Chief of the PTI, pointed out in the media that has been used recycled PET in hot fill packaging restricted fractions, in particular by requiring manufacturers of packaged food, and the study of the consulting firm maintains that the portion of the recovered can go up to 50% level in the composition of the raw material in the bottles in question. In his research, PTI''s team assessed the behavior of recycled PET in levels of 25% and 100% of .50% half-liter bottles from preforms of 27 grams. Even in the tests in which he was the only recycled material, stated the vice President Tracy Momany, packing performance in hot-filling was acceptable, although the walls accuse light haze or yellowing. The tests also aferiram topics as color, thickness, crystallinity and acetaldehyde content. In tests with, above 50% levels of recycled, the consultancy found penchant for shrinkage of the bottle. But up to the limit of 50% recycled, concluded the researchers, hot fill container performance meets expectations physical, chemical and optical, in addition to accentuate their appeal and result in sustainable savings of Virgin PET production.
