Cov hnab ntim khoom lag luam feem ntau yog tsim los ntawm polypropylene (PP), cov khoom siv thermoplastic polymer. Los ntawm yaj extrusion, cov khoom yog ua tiav rau hauv cov kab xev tiaj, uas yog tom qab ntawd woven los tsim cov ntaub nrog lub zog tseem ceeb. Polypropylene is characterized by low density, high strength, and excellent abrasion resistance, enabling it to meet the fundamental requirements for load-bearing capacity and durability in industrial packaging; yog li ntawd, nws yog dav siv rau ntim cov ntaub ntawv xws li cement, tshuaj raw khoom, mineral khoom, thiab yas granules.
Txhawm rau txhim kho kev ua haujlwm tag nrho ntawm cov hnab ntim khoom lag luam, cov khoom siv ua haujlwm feem ntau tau muab tso rau hauv lub hauv paus polypropylene. Piv txwv li, antioxidants ncua cov khoom aging, thaum UV stabilizers txhim kho huab cua tsis kam, ua rau lub hnab haum rau sab nraum zoov cia; Tsis tas li ntawd, kev suav nrog cov xim masterbatches tso cai rau xim -coding, ua kom yooj yim rau kev faib khoom thiab kev tswj hwm. Cov additives no optimize lub hnab ua haujlwm ua haujlwm yam tsis muaj kev cuam tshuam nws cov khoom tseem ceeb.
Nyob ntawm cov kev xav tau tshwj xeeb hauv kev lag luam, cov hnab no kuj tseem tuaj yeem siv cov qauv sib xyaw. Piv txwv xws li laminating ib tug polyethylene (PE) zaj duab xis mus rau lub woven txheej los txhim khu kev ya raws thiab dej tsis kam, los yog ntxiv ib tug sab hauv liner los txhim kho sealing thiab xau- pov thawj muaj peev xwm. Xws li ntau- cov khoom sib xyaw ua ke ua haujlwm tau zoo nthuav dav ntawm daim ntawv thov, tso cai rau lub hnab kom ua tau raws li cov kev xav tau ntim hauv cov chaw ua haujlwm nyuaj.
