聚酯PET熱灌裝飲料瓶基礎知識概述（PPT 43頁)內容簡介
Heat-resistant bottles 熱灌裝瓶
Specifics
Basic principle 基本原理
Blow-molding of PET bottles to withstand high temperatures
with no deformation所吹製的PET瓶必須能承受高溫而不變形
standard bottles are deformed under the effect of heat from 60 °C upwards
標準的瓶子加熱至60 °C 以上開始變形
adaptation of heat conditioning and blow-molding processes
enables bottles to withstand temperatures of up to 88°C
適當的加熱條件和吹瓶工藝能使瓶子承受88°C的溫度
Application to the packaging of sensitive drinks such
as isotonics, fruit juices, teas etc.
應用作敏感飲料包裝例如
等壓、果汁、茶等
Hotfilling 熱灌裝
Pasteurization 巴氏殺菌
Operating method操作方法
The liquid is raised to a temperature enabling it to be sterilized
液體溫度提升至能滅菌的溫度
The bottle is filled at this temperature (up to 88°C)
瓶子在這溫度下(高至 88°C)灌裝
Sterlization of the cap is obtained by contact with the hot liquid
瓶蓋與熱的液體接觸進行滅菌
Gradual cooling 分段冷卻
Specific stress factors
特殊的應力因素
Inflation then collapsing 膨脹後扁平
Local deformation 局部變形
Contraction 收縮
Inflation then collapsing膨脹後扁平
Rise in temperature of the material combined with mechanical stress
含有機械應力的材料溫度升高
material is softened, easily deformed
材料變軟，容易變形
Hydrostatic pressure exerted by the liquid on the walls: bottle inflation
液體在瓶壁上產生向外的靜壓：瓶膨脹
Expansion of the air in the head area: increased inflation
頂部空氣膨脹：增加膨脹
Effect of internal vacuum pressure resulting from the cooling of
the liquid and the air in the head area: phenomenon known as “collapsing”
由液體和瓶頸空氣冷卻而產生真空壓力：已知現象如
Local deformation局部變形
Stress exerted locally during packaging
在包裝過程中外界壓力局部地作用
Mechanical stress exerted by the cap: risk of deformation
封蓋的機械應力：變形的風險
