??鋁箔袋常見結構有:PET/PA/PE或者CPPPET/AL/CPPPA/AL/CPPPET/PA0/AL/CPP基本特點(dian)有:其中(zhong)PE適合(he)低溫(wen)的使(shi)(shi)用,CPP適合(he)高溫(wen)的蒸煮(zhu)使(shi)(shi)PA是為了增(zeng)(zeng)(zeng)加(jia)物理強度,耐穿刺性(xing)能(neng),AL鋁(lv)箔(bo)是為了增(zeng)(zeng)(zeng)加(jia)阻隔性(xing)能(neng),奶(nai)茶封(feng)口機遮光一般作為中(zhong)間層PET,增(zeng)(zeng)(zeng)加(jia)機械強度,挺括。玩具吸(xi)塑封(feng)口機然后根據(ju)需求,組(zu)合(he),各種性(xing)能(neng),也有透明的,為了增(zeng)(zeng)(zeng)加(jia)阻隔性(xing)
