Nyob rau tam sim no, qhov kev thov rau ntawv pearl siv nyob rau hauv kev ntim thiab cov cim luam ntawv yog ntau zuj zus. Txawm hais tias nws siv hauv PVC, PET, PE, PP hlaws ntawv rau cov ntawv ntim khoom lag luam thiab cov cim lag luam luam ntawv, nws muaj cov nyhuv zoo. Ntxiv rau nws qhov tsos zoo nkauj thiab kho kom zoo nkauj zoo nkauj, nws tseem muaj cov yam ntxwv zoo heev. Piv txwv li, hauv kev ntim cov dej txias, feem ntau ntawm cov ntawv ntim thawj dhau los ntawm cov yeeb yaj kiab yas ib-txheej yas tau tshem tawm, thiab lawv tau maj mam hloov mus rau high-end ntau-txheej, ua haujlwm (xws li cov khoom tsis zoo, ultra-qis. txias) thiab pearlescent ntawv nrog hlaws luster. pob.
Kev tsim cov ntawv hlaws feem ntau yog ua los ntawm polypropylene resin ua cov khoom siv raw, calcium carbonate thiab pearlescent pigments tau ntxiv, thiab cov khoom sib xyaw yog biaxially ncab. Vim txoj kev siv tshuab ua npuas ncauj, txoj kev nqus tshwj xeeb ntawm cov ntawv hlaws tsuas yog txog 0.7, thaum lub zog nqus ntawm PP yog kwv yees li 0.9, yog li cov tuam txhab ntim khoom lag luam yooj yim txaus siab xaiv nws vim nws tus nqi qis, kho kom zoo nkauj thiab zoo heev. Yog tias koj xav ua lub hnab ntim khoom kub nrog lub qhov tev zoo, nws yuav tsum muaj laminated, uas yog, laminating. Hauv kev ua ntau lawm txheej txheem ntawm cov ntawv hlaws, cov particle calcium carbonate masterbatch yog uniformly dispersed hauv homopolymer PP. Thaum PP tiv tau, ntau qhov tsim tau. Nws yog cov qhov no uas tsis kam lees lub teeb thiab ua cov nyhuv pearlescent.
Ntxiv rau qhov kub-sealable hlaws ntawv BOPP, kuj tseem muaj peb-txheej copolymer tsis-tshav kub-sealable BOPP pearl ntawv, uas yog, ob txheej ntawm homopolymer PP nrog txheej txheej txheej txheej. Qhov tseeb, BOPP pearlescent / LDPE (CPP) cov khoom siv feem ntau yog siv los ua kom tau raws li peb cov kev xav tau. BOPP pearlescent ntawv muaj lub teeb xim dawb pearlescent xim, uas tuaj yeem muaj kev cuam tshuam ntau lub teeb, thiab nws cov khoom siv roj av thiab cov khoom tiv thaiv dej kuj zoo dua li lwm hom BOPP zaj duab xis.
Muab ob npaug rau txheej txheem kub coj los ua daim ntawv hlaws BOPP nrog tuab 3μm tuaj yeem siv ncaj qha rau cov khoom qab zib, dej khov thiab lwm yam ntim dej txias, thiab tseem tuaj yeem siv rau cov khaub noom ntim hauv ncoo, chocolate, thiab xab npum ntim. Qhov ob npaug-ob daim ntawv kub kub ntim BOPP pearlescent ntawv nrog tuab 30μm yog dav siv hauv cov ntim khoom qab zib, khoom qab zib, khaub noom, thiab khoom noj txom ncauj. Ntxiv rau qhov kev thov ntawm BOPP hlaws ntawv nyob rau hauv ntim hloov tau, ntau qhov ntawm nws yog siv rau hauv cov khoom ntim khoom plig, thiab ib qho xov me me zoo tshaj tuaj yeem qhia kev ua phooj ywg. Kev siv dav ntawm pearlescent ntawv hauv cov ntawv ntim dej txias yog feem ntau cuam tshuam rau kev lag luam thiab nws tus kheej cov yam ntxwv.
