Cia peb tham hnub no txog hom kev ntim khoom nrov tshaj plaws hauv peb lub tebchaws thiab, tej zaum, thoob plaws ntiaj teb. Cov no yog cov hnab yas. Peb kawm paub ntau ntxiv txog lawv cov yam ntxwv, lub hom phiaj, khiav ntau yam. Peb yuav xyuam xim feem ntau rau kev faib tawm ntawm hom ntim no.

hnab, hnab yas

Ntim hnab yas pib tsim nyob rau hauv nruab nrab ntawm lub xyoo pua xeem. Thaum xub thawj lawv tau siv los ntim cov txiv hmab txiv ntoo thiab qhob cij. Tam sim no, kev tsim cov ntim khoom no nce mus txog 4.5 trillion daim ib xyoos ib zaug!

Lub thawv yas, polyethylene muaj lub hauv paus nyias nyias, uas yog tsim los ntawm ethylene, gaseous hydrocarbon. Kev txiav txim los ntawm cov xwm txheej ntawm cov tshuaj tiv thaiv polymerization, cov khoom tuaj yeem ua raws li hauv qab no:

• HDPE (PNED) - tsim nyob rau hauv lub xub ntiag ntawm catalysts, nyob rau hauv qis siab. Lub hnab no yog opaque, rustling rau kov.
• PVD (PVED) - tau txais los ntawm kev kub siab. Qhov tshwm sim yog ib yam khoom ntawm me ntsis qis dua. Cov khoom tiav yog pob tshab, mos, elastic, du rau waxy. Lwm qhov zoo tshaj plaws ntawm nws yog tias nws muaj peev xwm tiv taus cov khoom loj vim muaj zog intermolecularsib.
• Ntim los ntawm linear, nruab nrab ntom polyethylene, polyethylene sib xyaw ntawm ntau hom. Cov khoom kawg hauv nws cov khoom muaj nyob nruab nrab ntawm LDPE thiab HDPE.

Cov khoom ntim khoom

Muaj ob lub hnab polyethylene ntom ntom ntom ntom ntom ntom ntom ntom ntom. Cia peb qhia txog lawv cov khoom siv:

• Resistant rau cov tshuaj nquag nquag - acids, rog, alkalis, thiab lwm yam.
• Tua kua muag thiab lub zog tensile.
• Khaws nws cov khoom tseem ceeb txawm tias qhov kub thiab txias (tsuas yog ntawm -60 ° C tsuas yog cov khoom ua nkig).
• Resistant rau biodegradation, soaking.
• Tsis muaj tshuaj lom, uas tso cai rau kev sib cuag nrog cov khoom noj.
• Muaj khoom vim khoom pheej yig.
• YHygienic polyethylene.
• Impervious rau cov kua, gases, uas guarantees kev tiv thaiv ntawm cov ntsiab lus los ntawm tsis xav tau ib puag ncig yam.
• Polyethylene yog thermoplastic - feem ntau ntawm nws cov ntau yam pib yaj ntawm qhov kub siab tshaj 80-90 ° C. Qhov no ua rau lub hnab ua los ntawm cov khoom siv no tsis tsim nyog rau khaws cov zaub mov kub!

Sib piv nrog lwm cov ntaub ntawv

Sib piv cov hnab yas opaque thiab pob tshab nrog ntim ua los ntawm cov khoom sib txawv.

YPolyethylene	Qhov txiaj ntsig tseem ceeb yog cov khoom ntim pheej yig tshaj.
Cellophane	Yog qhov tshwm sim ntawmua pulp. Qhov tsis zoo tseem ceeb yog thaum lub kua muag me me tshwm, nws tawg ntxiv yuav luag tam sim.
paper	Kev ntim khoom ruaj khov tshaj plaws. Tab sis kiag li tsis haum rau greasy los yog ntub cov ntsiab lus.
YPolypropylene	Tsis zoo li polyethylene, nws tuaj yeem tiv taus qhov kub thiab txias. Tab sis tsawg resistant rau ncaj qha tshav ntuj, punctures. Tsis pom zoo rau ntim cov khoom ntsim.

mus rau lub ntsiab lus tom ntej.

Packaging production

Lub hnab yas ua li cas? Lub rhuab polymer loj yog extruded los ntawm qhov tsim nyog loj extruder qhov. Ib hom ntawm lub tes tsho polyethylene yog tsim, los ntawm cov pob khoom ntawm ntau yam xav tau tsim.

Kev tsim khoom ntxiv yog muab faib ua cov hauv qab no:

• Rewinding rau hauv yob rau tom ntej tear-off raws kab perforation.
• Packing nyob rau hauv pob khoom ntawm ib tug tej yam ntawm daim.
• Kev tsim ntxiv ntawm lub hnab - kev teeb tsa ntawm cov khoom siv, tes.
• Printing dluab - ib-, ob-, multicolor.

hom pob khoom

Kev tsim cov hnab yas niaj hnub suav nrog kev tso tawm cov khoom hauv qab no:

• Cov hnab ntim khoom. Pob tshab, nyias, ua los ntawm ntau hom khoom siv polyethylene. Lub hom phiaj tseem ceeb yog kev ntim cov khoom.
• Packages-"T-shirts". Lawv tau txais lawv lub npe vim qhov tseeb tias cov duab, txoj hauj lwm ntawm tes zoo li cov khoom no.wardrobe. Cov khoom tseem ceeb yog HDPE. Feem ntau hauv cov khw muag khoom loj vim qhov dav, compactness, yooj yim nqa.
• Packages nrog kov. Outwardly zoo li lub hnab, lawv raug nqi me ntsis ntau dua "T-shirts". Khoom siv - PVD, linear polyethylene, sib tov. Kov ntawm no muaj ntau haiv neeg - hlua, yas, slotted, loops, thiab lwm yam.
• Packages nrog fasteners, xauv.
• hnab thoob khib nyiab rau kev xav tau thiab tsev neeg. Khoom siv - polyethylene ntawm txhua hom, recyclable. Tej zaum yuav muaj cov ntaub nplaum nruj, tuav.
• pob khoom muaj npe. Decorated nrog ib tug duab, kos ib lub logo, inscriptions, thiab lwm yam. Ib txoj hauv kev ntxiv los txhawb lub tuam txhab, kev lag luam, lwm lub koom haum.

Kev cais raws hom hauv qab

hnab yas kuj muab faib raws li hom hauv qab:

• Pav ca, seamless hauv qab. Ntawm cov hnab ntim quav, hom no muaj ntau heev. Nws yog qhov yooj yim thiab pheej yig tshaj kev xaiv. Lub seam tsuas yog pom ntawm ob sab ntawm lub pob. Ntim cov khoom hnyav, cov khoom uas muaj cov npoo ntse hauv lub hnab no yog qhov tsis xav tau. Ntawm tag nrho cov hauv qab no, qhov tsis ruaj khov tshaj plaws thaum sau.
• Pab seamed hauv qab. Hom ntau tshaj plaws. Lub seam ntxiv dag zog rau lub hnab, uas tso cai rau nws tiv taus qhov hnyav zoo. Hauv qab yog zoo ib yam li ntug ntawm lub hauv ncoo. Nws yog qhov zoo dua tsis muab cov khoom ntub dej tso rau hauv lub thawv, vim tias cov dej yuav ntim rau hauv qab ntawm lub hnab.
• Nrog folds, tiaj seam hauv qab. Cov pob ntawv zoo li no yog resistant rau tearing, ntau ntom. Hauv qablub hnab polyethylene yog tiaj thiab soldered. Zoo rau kev ntim khoom ntau. Lwm qhov ntxiv yog tias nws muaj qhov zoo nkauj tshaj plaws.
• Nrog rau hauv qab quav (cov quav nyob hauv qab). Lub ntsiab sib txawv ntawm xws li ntim yog tias cov folds nyob rau hauv qab, thiab tsis hla tag nrho cov dav ntawm lub pob. Qhov no muab lub thawv ruaj khov thaum sau.
• Lub hauv qab ntawm "lub hnub qub". Cov duab ntawm lub hnab yas zoo li no yog cylindrical, uas tso cai rau qhov hnyav ntawm cov khoom thauj mus rau qhov sib npaug thoob plaws hauv lub thawv. Lub hnub qub zoo li lub foob hauv qab tiv thaiv kom cov khoom ntub dej. Cov no yog cov hnab yas khib nyiab; lawv kuj tau siv dav hauv chaw ua noj.

hnab yas yog tsim nyob rau hauv ib tug loj assortment nyob rau hauv Russia thiab nyob ib ncig ntawm lub ntiaj teb no, los ntawm ntau yam raw khoom. Lawv muaj ntau qhov zoo thiab ntau qhov tsis zoo ntawm lwm hom ntim.
