Abstract

본 발명은 표면광택성이 우수한 플라스틱 병 및 그 제법에 관한 것으로, 보다 상세하게는 적어도 외표면이 올레핀수지로 형성되어 있으면서도 뛰어난 표면광택을 가지는 플라스틱 병 및 그 제법에 관한 것이다.
종래의 발명은 쳐짐의 방지에는 유효할지라도 용융분열의 방지에는 유효하지않고 성형된 용기벽은 표면광택이 모자라고, 또 투명성에 결함이 있고, 게다가 병에 넣은 제품으로 한 경우 병을 통한 내용물의 외관이 유리병에 넣은 제품에 비하여 상당히 떨어지는 것이되고, 상품가치가 떨어지는 것이 된다는 결점이 있다.
이를 개선하고자 본 발명은 적어도 외면이 올레핀계 수지로 구성된 플라스틱 병에 있어서, 상기 외면 올레핀계 수지가 하기식(1)
Y〈-AX+B (1)
