Kev lag luam zaub mov feem ntau siv BOPP ntim yas. BOPP hnab yog ib qho yooj yim luam tawm, tsho loj thiab laminate uas ua rau lawv haum rau cov khoom ntim xws li cov khoom tshiab, khoom qab zib thiab khoom noj txom ncauj. Nrog rau BOPP, OPP, thiab PP hnab kuj siv rau ntim. Polypropylene yog ib hom polymer ntawm peb siv los tsim cov hnab.
OPP stands rau Oriented Polypropylene, BOPP stands rau Biaxially Oriented Polypropylene thiab PP stands rau Polypropylene. Tag nrho peb qhov sib txawv hauv lawv cov style ntawm fabrication. Polypropylene tseem hu ua polypropene yog ib qho thermoplastic semi-crystalline polymer. Nws yog tawv, muaj zog thiab muaj kev cuam tshuam siab. Standup pouches, spout pouches thiab ziplock hnab yog tsim los ntawm polypropylene.
Nws yog qhov nyuaj heev rau kev sib txawv ntawm OPP, BOPP thiab PP yas thaum xub thawj. Qhov sib txawv tuaj yeem hnov los ntawm kev kov li PP yog mos thaum OPP yog nkig. Nws yog ib qho tseem ceeb kom nkag siab txog kev siv lub hnab OPP, PP thiab BOPP hauv cov khoom tiag tiag kom paub qhov txawv ntawm lawv. CovPPlossis polypropene hnab yog siv los ua cov hnab tsis-woven. Lawv raug kho thiaj li ua rau lawv ya raws los yog dej nqus.
Cov pawm, cov ntaub so ntswg huv thiab cov lim cua ntawm lwm tus yog cov khoom siv PP. Cov khoom zoo sib xws kuj tseem siv rau kev ua cov khaub ncaws thermal raws li lawv muab qhov ntsuas kub. OPP hnab yog pob tshab hauv cov xim thiab muaj lub zog tensile siab. Lawv tiv taus qhov kub thiab txias tab sis wrinkle yog tias coj mus rau hauv kev siv ntxhib. Pob tshab nplaum daim kab xev yog tsim los siv tib lub mis.
Lawv nyuaj rau tsim kua muag thiab OPP hnab yog siv los ntim cov tawv thiab khaub ncaws ntawm lwm tus. BOPP hnab yog siv lead ua ntshiab polyethylene hnab. Lub biaxial orientation muab lawv cov pob tshab saib thiab ua rau lawv tsim nyog rau kev lag luam los ntawm kev luam ntawv ntawm qhov chaw. BOPP hnab yog siv rau kev ntim khoom muag. Kev taw qhia biaxial nce lub zog thiab lawv tuaj yeem nqa cov khoom hnyav.
Cov hnab no tsis muaj dej.
Cov khoom nyob rau hauv lawv muaj kev tiv thaiv los ntawm ya raws rau lub sij hawm ntev. Lawv yog thawj qhov kev xaiv hauv kev lag luam ntim ntaub. PP, OPP thiab BOPP hnab yog resistant rau acid, alkalies thiab organic solvents. Qhov no yog vim li cas vim li cas lawv thiaj siv rau hauv kev lag luam ntim khoom qhov chaw khaws cia thiab kev thauj mus los hauv huab cua hloov pauv tsis tuaj yeem zam tau. Lawv npaj cov khoom los ntawm cov dej noo thiab hmoov av zoo li cling films.
Lawv tuaj yeem rov ua dua thiab lawv cov khoom tsim muaj cov pa roj carbon tsawg dua. PP, BOPP thiab OPP hnab kuj zoo los ntawm ib puag ncig kev pom. Rishi FIBC yog lub chaw tsim khoom BOPP hnab thiab muab nws ntawm tus nqi pheej yig.
