Qhov txawv ntawm PP hnab thiab BOPP hnab yog dab tsi?

Polypropylene hnab (polypropylene hnab) thiab BOPP hnab (biaxially oriented polypropylene hnab) sib txawv heev nyob rau hauv cov ntaub ntawv, manufacturing txheej txheem, lub cev muaj zog thiab kev siv. Qhov txawv tshwj xeeb yog raws li nram no:
I. Khoom siv thiab kev tsim khoom
PP hnab
Khoom siv: Ua los ntawm polypropylene zoo tib yam (PP) los ntawm tshuab moulding lossis casting txheej txheem.
Txheej Txheem: Tsis yog bidirectional, tsis yog cov qauv molecular bidirectional.
Nta: Tus nqi qis, cov txheej txheem yooj yim, tab sis kuj tsis tshua muaj cov khoom kho qhov muag (xws li pob tshab thiab gloss) thiab lub zog txhua yam.
BOPP hnab
Khoom siv: Ua los ntawm polypropylene granules los ntawm cov txheej txheem biaxially oriented.
Txheej txheem: Ib txhij ob leeg longitudinal thiab transverse kev taw qhia tensile, ua rau molecular orientation, ua rau lub zog siab, siab transparency zaj duab xis.
Nta: Cov txheej txheem ntau lawm yog complex, tab sis qhov kev ua tau zoo yog pom tseeb, lub pob tshab zoo ib yam li cellophane, lub zog txhua yam yog siab thiab noo noo kuj zoo heev.
ii. Kev sib piv ntawm lub cev muaj zog
Performance PP hnab BOPP hnab
Transparency Tsawg, me ntsis huab, ze rau cellophane
Gloss nruab nrab zoo heev, du tiav
Mechanical Strength Low, siab kua muag kuj, tensile thiab puncture kuj.
Zoo noo noo tsis kam, tsis muaj noo noo permeability
Tsis zoo txias tsis kam, zoo brittleness ntawm qis kub, tsis nkig ntawm -30 ° C ~ 50 degree
Thaum tshav kub kub-Kev sib khi tuaj yeem ua kom sov ncaj qha. Ib zaj duab xis tsis tuaj yeem ua kom sov thiab yuav tsum tau ua ke nrog lwm cov ntaub ntawv
Tsawg hardness, siab deformation, lub hnab tawv.
III. Qhov sib txawv ntawm daim ntawv thov
PP hnab
Haum rau: ntim yooj yim, lub sijhawm ua haujlwm luv, kev ua haujlwm tsawg.
Daim ntawv thov tshwj xeeb:
Cov hnab ntim khoom pov tseg, hnab khib nyiab;
Kev ntim khoom noj dav dav (piv txwv li, txiv hmab txiv ntoo qhuav, khoom qab zib);
Cov khoom ntim khoom lag luam (piv txwv li, cov ntsia hlau, cov khoom siv me me).
BOPP hnab
Tsim nyog rau Scenarios uas xav tau kev siv siab, pob tshab lossis ntev - khaws cia ntev.
Daim ntawv thov tshwj xeeb:
Cov ntim khoom noj: biscuits, qos yaj ywm chips, khoom noj khov, thiab lwm yam. (feem ntau siv CPP lossis PE laminated ntim);
Ntim Cov Khoom Siv Txhua Hnub: Tshuaj pleev ib ce, tshuaj ntxuav tes;
Kev ntim khoom: chiv, pub, khoom siv hauv tsev;
Printing Substrate: highprecision printing (xws li, trademarks, qauv), vim nws du nto, zoo number case nqus.
IV. INTRODUCTION Txheej txheem cej luam ntawm Core Advantages
PP hnab: Tus nqi qis, ua haujlwm yooj yim, sib khi thaum tshav kub kub, haum rau luv luv -lub sij hawm lossis ib zaug - siv.
BOPP Hnab: Kev ua tau zoo heev (lub zog siab, pob tshab, tsis muaj dej noo), kev luam ntawv zoo, haum rau lub sijhawm ntev - khaws cia lossis siab - kawg ntim, tab sis yuav tsum tau ua ke nrog lwm cov ntaub ntawv rau kev sib khi.
V. Cov lus pom zoo xaiv
Yog tias koj xav tau- tus nqi qis, ntim khoom yooj yim thiab xav tau kev sib khi, xaiv lub hnab PP.
Yog tias muaj lub zog siab, pob tshab lossis ntev ntev - yuav tsum tau khaws cia, thiab xav tau cov ntawv luam tawm, xaiv lub hnab BOPP (cov khoom siv hluav taws xob sib khi nrog PE lossis CPP txheej).
