Cov lag luam zaub mov feem ntau siv cov yas ntim khoom BOPP. Cov hnab BOPP yooj yim luam tawm, txheej thiab laminate uas ua rau lawv haum rau kev ntim cov khoom xws li cov khoom tshiab, khoom qab zib thiab khoom noj txom ncauj. Nrog rau BOPP, OPP, thiab PP hnab kuj siv rau kev ntim khoom. Polypropylene yog ib qho polymer feem ntau ntawm peb yam siv rau kev tsim cov hnab.
OPP sawv cev rau Oriented Polypropylene, BOPP sawv cev rau Biaxially Oriented Polypropylene thiab PP sawv cev rau Polypropylene. Peb yam no sib txawv hauv lawv txoj kev tsim khoom. Polypropylene tseem hu ua polypropene yog cov thermoplastic semi-crystalline polymer. Nws yog tawv, muaj zog thiab muaj kev tiv taus kev cuam tshuam siab. Cov hnab sawv ntsug, cov hnab spout thiab cov hnab ziplock yog ua los ntawm polypropylene.
Thaum xub thawj nws nyuaj heev rau kev sib txawv ntawm OPP, BOPP thiab PP yas. Qhov sib txawv tuaj yeem hnov los ntawm kev kov vim PP yog mos thaum OPP yog brittle. Nws yog ib qho tseem ceeb kom nkag siab txog kev siv OPP, PP thiab BOPP hnab hauv cov khoom tiag tiag rau kev sib txawv ntawm lawv. LubPPlos yog cov hnab polypropene siv ua cov hnab tsis woven. Lawv raug kho kom ua rau lawv nqus dej noo lossis dej.
Cov ntaub so ntswg, cov ntaub so huv thiab cov lim cua ntawm lwm yam yog cov khoom PP feem ntau. Cov khoom zoo sib xws kuj siv rau kev ua khaub ncaws sov vim lawv tiv thaiv qhov kub thiab txias. Cov hnab OPP muaj xim pob tshab thiab muaj lub zog tensile siab. Lawv tiv taus qhov kub thiab txias siab tab sis wrinkle yog tias coj mus siv tsis zoo. Cov ntaub nplaum pob tshab yog ua los ntawm tib cov mis.
Lawv nyuaj rau rhuav thiab cov hnab OPP siv rau hauv kev ntim cov tawv thiab khaub ncaws thiab lwm yam. Cov hnab BOPP yog cov hnab polyethylene ntshiab. Qhov kev taw qhia biaxial ua rau lawv zoo li pob tshab thiab ua rau lawv haum rau kev tsim hom los ntawm kev luam tawm ntawm qhov chaw. Cov hnab BOPP siv rau kev ntim khoom muag. Qhov kev taw qhia biaxial ua rau muaj zog dua thiab lawv tuaj yeem nqa cov khoom hnyav.
Cov hnab no tsis ntub dej.
Cov khoom hauv lawv tau tiv thaiv kom tsis txhob muaj dej noo ntev. Lawv yog thawj qhov kev xaiv hauv kev lag luam ntim ntaub. Cov hnab PP, OPP thiab BOPP tiv taus cov kua qaub, alkalies thiab cov kuab tshuaj organic. Qhov no yog qhov laj thawj vim li cas lawv thiaj siv rau hauv kev lag luam ntim khoom uas tsis tuaj yeem zam kev khaws cia thiab kev thauj mus los hauv huab cua hloov pauv. Lawv tso cov khoom tawm ntawm cov dej noo thiab hmoov av zoo li cov yeeb yaj kiab lo.
Lawv tuaj yeem rov ua dua tshiab thiab lawv cov khoom tsim muaj cov pa roj carbon tsawg dua. Cov hnab PP, BOPP thiab OPP kuj zoo los ntawm qhov pom ntawm ib puag ncig. Rishi FIBC yog lub chaw tsim khoom hnab BOPP thiab muab nws ntawm tus nqi lag luam pheej yig.
