Izinto ezijwayelekile zezikhwama zokupakisha zepulasitiki:
1. I-polyethylene
I-polyethylene, esetshenziswa kakhulu ezikhwameni zokupakisha zepulasitiki. Ikhanya futhi isobala. Inezinzuzo zokumelana nomswakama ofanele, ukumelana komoya-mpilo, ukumelana ne-asidi, ukumelana ne-alkali, ukuvala uphawu lokushisa, njll., futhi ayinabuthi, ayinambitheki futhi ayinaphunga. Izindinganiso zokupakisha zenhlanzeko. Yimpahla efanelekile yezikhwama zokudla emhlabeni wonke, futhi izikhwama zokupakisha ukudla emakethe ngokuvamile zenziwe ngale nto.
2. I-Polyvinyl chloride/PVC
Iwuhlobo lwepulasitiki lwesibili ngobukhulu emhlabeni ngemuva kwe-polyethylene. Kuyinketho ekahle yezikhwama zokupakisha zepulasitiki, izikhwama ze-PVC, izikhwama eziyinhlanganisela, nezikhwama zevacuum. Ingase futhi isetshenziselwe ukupakisha nokuhlobisa amakhava njengezincwadi, amafolda, namathikithi.
3. I-polyethylene ye-low density
I-Low-density polyethylene iyinhlobonhlobo esetshenziswa kakhulu ezimbonini zokupakisha nezokuphrinta zepulasitiki zamazwe ahlukahlukene. Ilungele ukubunjwa kwe-blow ukuze icutshungulwe kumafilimu ama-tubular, futhi ifanele ukupakishwa kokudla, ukupakishwa kwamakhemikhali nsuku zonke, kanye nokupakishwa komkhiqizo we-fiber.
4. I-polyethylene ephakeme kakhulu
I-polyethylene ephezulu, ukumelana nokushisa, ukumelana nokupheka, ukumelana nokubanda futhi ukumelana neqhwa, umswakama-umswakama, i-gas-proof kanye ne-insulating, akulula ukonakala, futhi amandla ayo aphindwe kabili kune-polyethylene ephansi. Kuyinto evamile yezikhwama zokupakisha zepulasitiki.
I-Huizhou Dingli Packaging Products Co., Ltd., umkhiqizi wezikhwama zepulasitiki ochwepheshile, uneminyaka engu-16 yesipiliyoni sokwenza ngokwezifiso izikhwama zokupakisha zepulasitiki, futhi ingakunikeza izikhwama zepulasitiki eziqondene nawe, izikhwama zamaphepha, amabhokisi, amabhokisi e-pizza, amabhokisi e-hamburger, iqhwa. izitsha zikakhilimu, ukudla Ukubonisana namanani ezikhwama zokupakisha, izikhwama zamazambane zokufaka amashidi, izikhwama zokupakisha ukudla okulula, izikhwama zokupakisha zekhofi, izikhwama zokufaka ugwayi, izikhwama zokupakisha ezenziwe ngokwezifiso nepulasitiki, kanye nokupakisha kwamaphepha.
Izinto ezijwayelekile zezikhwama zokupakisha zepulasitiki zimi kanje:
1. Isikhwama sepulasitiki se-PE
I-Polyethylene (PE), ebizwa ngokuthi i-PE, iyinhlanganisela ephezulu yamangqamuzana etholakala ngokuhlanganisa i-polymerization ye-ethylene. Kubhekwa njengento enhle yokuxhumana nokudla emhlabeni. I-Polyethylene ifaka umswakama, i-anti-oxidant, imelana ne-asidi, imelana ne-alkali, ayinabuthi, ayinambitheki, ayinaphunga, futhi ihambisana nezindinganiso zokuhlanzeka zokupakisha ukudla, futhi yaziwa ngokuthi “imbali yepulasitiki”.
2. Izikhwama zepulasitiki ze-PO
Ipulasitiki ye-PO (i-polyolefin), ebizwa ngokuthi i-PO, i-polyolefin copolymer, okuyi-polymer etholakala kuma-olefin monomers. I-Opaque, i-brittle, ayinabo ubuthi, evame ukusetshenziswa njengamaphakethe e-PO flat, izikhwama ze-PO vest, ikakhulukazi izikhwama zepulasitiki ze-PO.
3. Isikhwama sepulasitiki se-PP
Isikhwama sepulasitiki se-PP yisikhwama sepulasitiki esenziwe nge-polypropylene. Ngokuvamile yamukela ukuphrinta kombala, ukuphrinta kwe-offset, futhi inemibala egqamile. Ipulasitiki ye-polypropylene enwebekayo futhi ingeyohlobo lwe-thermoplastic. Indawo engeyona enobuthi, engenaphunga, ebushelelezi futhi esobala.
4. Isikhwama sepulasitiki se-OPP
Izinto zesikhwama sokupakisha sepulasitiki se-OPP yi-polypropylene, i-polypropylene eyi-bidirectional, ebonakala ngokushiswa kalula, ukuncibilika nokuconsa, okuphuzi phezulu nokuluhlaza okwesibhakabhaka phansi, intuthu encane ngemva kokushiya umlilo, futhi iyaqhubeka ivutha. Inezici zokungafihli okuphezulu, ukubola, ukubekwa uphawu okuhle kanye nokuphikisana okuqinile kokwenziwa komgunyathi.
5. Izikhwama zepulasitiki ze-PPE
Isikhwama sepulasitiki se-PPE siwumkhiqizo okhiqizwe inhlanganisela ye-PP ne-PE. Umkhiqizo awukwazi ukumelana nothuli, ulwa namagciwane, uvikela umswakama, u-anti-oxidation, ukumelana nokushisa okuphezulu, ukumelana nezinga lokushisa eliphansi, ukumelana nowoyela, awunobuthi futhi awunambitheki, obala okuphezulu, izakhiwo ezinamandla zemishini, anti-blasting Ukusebenza okuphezulu, okuqinile ukumelana nokubhoboza kanye nokumelana nezinyembezi.
6. Izikhwama zepulasitiki zika-Eva
Isikhwama sepulasitiki se-EVA (isikhwama esifakwe isithwathwa) senziwa ikakhulukazi ngezinto eziqinile ze-polyethylene nezinto eziqondile, eziqukethe u-10% wempahla ye-EVA. Ukucaca okuhle, umgoqo we-oxygen, umswakama-ubufakazi, ukuphrinta okukhanyayo, umzimba wesikhwama esikhanyayo, ungazama ukugqamisa izici zomkhiqizo ngokwawo, ukumelana ne-ozone, i-flame retardant nezinye izici.
7. Izikhwama zepulasitiki ze-PVC
Izinto ze-PVC zifaka isithwathwa, okusobala okujwayelekile, okusobala kakhulu, ubuthi obuphansi obunobungani bemvelo, izinto ezingezona ezinobuthi ezithinta imvelo (i-6P ayiqukethe ama-phthalates namanye amazinga), njll., kanye nerabha ethambile neqinile. Iphephile, ihlanzekile, ihlala isikhathi eside, inhle futhi iyasebenza, inokubukeka okuhle nezitayela ezahlukahlukene, futhi kulula kakhulu ukuyisebenzisa. Abakhiqizi abaningi bemikhiqizo esezingeni eliphezulu ngokuvamile bakhetha izikhwama ze-PVC ukuze bazipakishe, bahlobise kahle imikhiqizo, futhi bathuthukise ikhwalithi yomkhiqizo.
Okuqukethwe okuchazwe ngenhla ngezinye zezinto ezivame ukusetshenziswa ezikhwameni zokupakisha zepulasitiki. Lapho ukhetha, ungakhetha izinto ezifanele ukwenza izikhwama zokupakisha zepulasitiki ngokwezidingo zakho zangempela
