PET的成型加(jia)工可以注塑、擠出、吹塑、涂覆、粘結(jie)、機加(jia)工、電(dian)鍍、真空鍍金屬、印刷。以下主(zhu)要介紹(shao)二(er)種。1.注塑級(ji)①溫度(du)設定：射(she)嘴：280~295℃、前(qian)段(duan)270~275℃、中鍛265~275℃、后段(duan)250-270℃；螺旋桿轉速50~100rpm、模具溫度(du)30~85℃、非(fei)結(jie)晶型之(zhi)模具為70℃一下、背壓5-15KG。②試用(yong)除濕干燥(zao)機、料管(guan)溫度(du)240~280℃、射(she)出壓力500~1400℃、射(she)出成型溫度(du)260~280℃、干燥(zao)溫度(du)120~140℃、須(xu)時2~5小時。

食用油的包裝

不(bu)(bu)(bu)同(tong)種(zhong)類(lei)的(de)食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)在食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)瓶(ping)的(de)使用(yong)(yong)(yong)上也有(you)的(de)著不(bu)(bu)(bu)同(tong)的(de)要(yao)求。有(you)些(xie)比(bi)如橄(gan)欖(lan)油(you)(you)(you)在包(bao)裝上需(xu)要(yao)食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)瓶(ping)以深色(se)為主(zhu)，以此(ci)來保(bao)護橄(gan)欖(lan)油(you)(you)(you)的(de)保(bao)存(cun)不(bu)(bu)(bu)受光線的(de)影響。而普(pu)通的(de)花生油(you)(you)(you)、大豆油(you)(you)(you)則以PET食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)瓶(ping)包(bao)裝為主(zhu)，在規格上以5L和1.8L居多(duo)。對于芝麻油(you)(you)(you)之類(lei)的(de)產品多(duo)以小容(rong)量的(de)玻璃食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)瓶(ping)包(bao)裝為主(zhu)。 應該說食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)的(de)市(shi)場還會不(bu)(bu)(bu)斷(duan)的(de)細分，而食(shi)(shi)(shi)用(yong)(yong)(yong)油(you)(you)(you)瓶(ping)企業則要(yao)在包(bao)裝上根(gen)據市(shi)場的(de)變化作出更(geng)多(duo)的(de)改(gai)變，以此(ci)贏得市(shi)場認可。
