Ukuh сравна Imitha Efanayo Yemithwana Yemithi

Ukutholakala Kwemithwana Yokuphatha

Ayikho inkxenye yokuphatha engcono kune imithwana yokuphatha ngokuphakama kwezindlela zokuphatha izinto ngaphandle kwalokho kuyakunceda ukubonakala kwezinto esitolo. Imithwana iyabangela futhi ngokusebenzisa kakhulu ngokuthi kungasebenziswe ukuphatha konke okungu kafe okuya kumathe. Futhi uma unelobha lezindlela zokuphatha engxenye ye-flexible, imithwana iyasiza kakhulu ngokuthi iyisisekelo sokuphatha okungu kwezindlela zokuphatha ezisebenzisa ngokudla. Imithwana iyakunceda ukuthi izinto zibe nezimali ezifulekile futhi zibe nesicelo sezingxenye ezifulekile, ngokwesibonelo ukuthi izinto zibe nezimali ezifulekile, lokhu kuyakunceda ukuthi ibhrendi noma ikhompani iyakunceda ukuthi kutholakale ukuthi kungaba yini okuthandekile ngokuphatha izinto.

Imithwana Yokuphatha Engenye Yezindlela Zokuphatha Nezindima Zazo

Okoku kusezinye i-polyethylene (PE), elingumunwe umfaniso wokubeka amaphethini. Kakhulu kuyithandwa xa kufika kwekupakatha into engculwa ngokuba uyimfushane fanye ne-seal amakhaza neyizililo. Kungenjalo kuyinkulu, njengoba uyibona kumathela amaphethini okubeka fanye noma kwezililo zokupakatha izindlela zemasi, kudinga izindleko ukuthi ikhupheke, okuyindlela yokusebenza kwekupakatha ngemzuzwana.

Kunakho i-polypropylene (PP) umfaniso wokubeka amaphethini. Le ndawo yinkimbinkimbi kancane olwandle PE, kodwa isebenza ngokufanele kwekupakatha. Ishiywe kahle kumaphethini ofuna okuncane ukuthi ibe ngemfanelo, njengoba kubekwa kwezindlela zokupakatha izindlela zemasi noma izindlela zokupakatha izindlela zemasi. Ngaphezulu, i-PP iyathola ukuthi ikhule, ngakho iyisimo esifanele sokusebenzisa kwekupakatha lapho kusebenzisa ukuthi ikhule kumoya wokupakatha. Ngenkqubo yokubona kwePP, abathengi bafuna ukubona kahle into ngaphakathi kwekupakatha.
  
Into engxenye yokuqala esetshenziswa yisikhathi singama-polyester (PET) roll film. I-PET iyinkani futhi inezinhlobo zokugcina okuhle, ikhokha izinto ezifana ne-oksijeni nohlango lwezinye izinhlobo zokupakisha. Lokhu kwenza ukupakisha kwe-PET kube lula kakhulu kwezinto ezinemva elide futhi ezithuthwa ngokushesha njengokushona nezintanga. Futhi, iyilanga futhi inokuthokozisa kakhulu ukuprinta okwengeziwe. Ngalesi sikhali, i-PET isithandwa kakhulu yizikhwama ezingathanda ukuthutha kakhulu kuzo ukupakisha. Noma ngiyinkani ngokulinganisa ne-PE, i-PET isebenza ngokushesha kwayo ngisho noma iyinkani kwayo ngisho noma ikhululwe.

Kungani UkuKhetha Umbango Wemateriali Yefilim

Imithwanciso egciniweyo ye-roll film iyathatha iqhuma elitheni lifilwe ngokutheni. Kuma maphetheni amathotho njengama sauce angaphansi kanye nezinkhenkhe zokudla, lifilwe le PE etholakala kakhulu ngokuthola okungcolayo. Kuma maphetheni angafanele uthuthwe kakhulu njengama chips kanye nokubeka kwechipboard box, lifilwe le PP itho kakhulu kanye nokugcina okuphephile kuzothatha chipboard box ukuthi akwazi ukulwa. Kuma maphetheni abonakalayo kakhulu kanye nezixwayiso njengama coffee beans amathile kanye nezinhlanzi ezitholakalayo, lifilwe le PET inemithwanciso ephakeme kakhulu yokuvikela ukungabi lula.

Fikela futhi ngokusebenzela kwekhombisa. Ingabe, isihlangu, isihlangu kufanele sibekwe kabusha? Ngezipper closure esihlukaniswe, lifilwe le PE sikhathazo. Uma isihlangu kufanele sibonakale ngama rhamu amaningi kanye nezinto ezinhle, isethu le PET noma le PP itho elikhulu kakhulu lokubona izinto eziyinkimbinkimbi.

Ukuphepha kuyakile kakhulu—wonke le mithwanciso leli bantfu labo abathinta ukudla kuyimithwanciso engcono yokudla, ngakho-ke kuzothathwa ngokuthi kuyakile.

Kungani Kukhetha Imithwana Efanayo Kuyindlela Ebuhle Kwezimali Eziphakathiweyo

Uma into engavumelekile ekhethwe, izimali eziphakathiweyo zingakusebenza ngendlela ethintekayo. Le meqo engeke iyaphumelele kakhulu kuleyo maphakathi ukuba yimali enkulu, amasele awaphansi, noma ukungakwazi ukulungisa amandla. Lokhu kungavumelekanga inqubo, kodwa kuyayikhuphisa amathuba okuthenga futhi umkhiqizo ngokuphelele. Ngakolunye uhlango, uma unemithwana efanayo, leyo maphakathi ingakuba yimali enkulu, inqo lokusebenzela, futhi yonke into ingakuxazulula umphakathi. Lezi zinto zizonke zozokunika amandla kwezimali ukuthola ukuthemba kwezimpendulo.

noma ukungakwazi ukulungisa amandla. Lokhu kungavumelekanga inqubo, kodwa kuyayikhuphisa amathuba okuthenga futhi umkhiqizo ngokuphelele. Ngakolunye uhlango, uma unemithwana efanayo, leyo maphakathi ingakuba yimali enkulu, inqo lokusebenzela, futhi yonke into ingakuxazulula umphakathi. Lezi zinto zizonke zozokunika amandla kwezimali ukuthola ukuthemba kwezimpendulo.

I-PE roll film ungasebenzisa ngokwengeza ukuba amachips ayishe ngeminyaka engama-2, noma umbandela wemoto ungavikela ukuba kungcolwa ukuphazamiseka kwamaphethole PET. Ukucindezela iphakheji noma ukuthembeka kwezinye izinto kungaba nokuthanda kakhulu. Lezi zinto zibonisa ukucabanga nokuzithemba esetshenziswe kuziphakamise iphakheji elayishwayo. I-roll film ehambelana ngeyodwa ayisebenzi kuphela ngokuthileyo yokuthenga kumakhasi—kungenxa yento etholakala ngokuhluke kakhulu kuzo zonke izindidi zemikhiqizo.
