본 발명은 산소, 이산화탄소 및/또는 수증기의 투과에 대하여 우수한 장벽 특성을 보유하는 경량 폴리에틸렌 테레프탈레이트 병의 제조 방법에 관한 것이다. PET 병의 형성 동안의 상대적으로 적은 양의 폴리에틸렌 푸란디카르복실레이트의 사용은 요구되는 장벽 특성을 갖는 병을 생성하며 더 적은 재료의 사용으로 이어질 수 있다. The disclosure relates to processes for producing lightweight polyethylene terephthalate bottles that retain good barrier properties against the permeation of oxygen, carbon dioxide and/or water vapor. The use of relatively small amounts of polyethylene furandicarboxylate during the formation of the PET bottles can produce a bottle having the required barrier properties and result in the use of less material.
