Paketi ya pulasitiki
Matumba a pulasitiki apulasitiki ndi chisankho chotchuka pazakudya zoziziritsa kukhosi chifukwa chokwanira, kusinthasintha, ndi mtengo wotsika. Komabe, sikuti zida zonse za pulasitiki ndizoyenera kudyetsa zakudya. Nazi zina mwazipatso zambiri zomwe zimagwiritsidwa ntchito zikwama zodyera:
Polyethylene (pe)
Polyethylene amagwiritsidwa ntchito matumba apulasitiki ambiri. Ndi zinthu zopepuka komanso zosinthika zomwe zimatha kuumbidwa mosavuta mu mawonekedwe osiyanasiyana. Matumba amagonjetsedwanso ndi chinyezi ndipo amatha kusunga zakudya zazitali kwa nthawi yayitali. Komabe, matumba sayenera kuphika zakudya zotentha monga momwe amasungunuka pamphuno kwambiri.
Polypropylene (pp)
Polypropylene ndi zinthu za pulasitiki zolimba komanso zolimba zomwe zimagwiritsidwa ntchito zikwama zodyera. Matumba a PP amalimbana ndi mafuta ndi mafuta, kuwapangitsa kukhala abwino kuti akwaniritse zofufuzira zamafuta monga tchipisi ndi popcorn. Matumba a PP alinso microwave-otetezeka, omwe amawapangitsa kusankha kotchuka kwa kayendedwe ka chakudya.
Polyvinyl chloride (pvc)
Polyvinyl chloride, omwe amadziwikanso kuti PVC, ndi pulasitiki yomwe imagwiritsidwa ntchito m'matumba odyetseratu. Matumba a PVC ali osinthika komanso olimba, ndipo amatha kusindikiza mosavuta ndi mawonekedwe okongola. Komabe, matumba a PVC sayenera kuphika zakudya zotentha monga momwe angamasulire mankhwala ovulaza akamatenthedwa.
Mwachidule, matumba a pulasitiki odziwika bwino ndi chisankho chotchuka cha mabotolo osowa chifukwa cha kulimba kwawo, kusinthasintha, ndi mtengo wotsika. Komabe, ndikofunikira kusankha zinthu za pulasitiki zoyenera zogulira zoziziritsa kukhosi kuti zitsimikizire chitetezo komanso chambiri. Pe, pp ndi pvc ndi zina mwazipatso zambiri zomwe zimagwiritsidwa ntchito zikwama zodyera, iliyonse ndi zabwino zawo komanso malire.
Matumba a Biodegraded
Matumba am'masamba a biodegrader ndi njira yocheza ndi chilengedwe. Matumba awa adapangidwa kuti azitha kuphwanya mwachilengedwe kwakanthawi, kuchepetsa kuchuluka kwa zinyalala zomwe zimatha. Mitundu iwiri yofala ya zinthu zofananira yomwe imagwiritsidwa ntchito m'matumba odyetseratu ndi polylactic acid (plu) ndi polyhyhyhyroxsya okondana (PE).
Polylactic acid (pl)
Polylactic acid (plu) ndi polymergradji yopangidwa ndi zothandizira za chimanga monga chimanga chowuma, nzimbe, ndi chinangwa. Play adatchuka m'zaka zaposachedwa chifukwa cha kuthekera kwake kusokoneza zachilengedwe. Komanso ndi lingaliro, kutanthauza kuti chitha kusweka mu zinthu zachilengedwe zomwe zingagwiritsidwe ntchito kubzala nthaka.
Pla imagwiritsidwa ntchito m'matumba odyetseratu matumba chifukwa ndi cholimba komanso cholimba, komabe pogwiritsa ntchito zinthu. Ilinso ndi njira yotsika ya kaboni yotsika, imapangitsa kuti ikhale njira yochezera zachilengedwe.
Ma polyhyhyroxyaxsya
Polyhydroxyaxyaxyaxyakolkaniates (gawo) ndi mtundu wina wa polimalgle polider yomwe ingagwiritsidwe ntchito m'matumba odyetseratu. Pulogalamu imapangidwa ndi mabakiteriya ndipo ndi biodeggrad okhala m'maiko osiyanasiyana, kuphatikizapo malo am'mimba.
Gawo ndi chinthu chosinthasintha chomwe chitha kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo ma suketi. Ndizolimba komanso zolimba, komanso zinthu zosakhazikika, ndikupangitsa kuti ikhale chisankho chabwino pa opanga zachilengedwe.
Pomaliza, matumba a biodaggrad omwe ali m'matumba monga plpi ndi gawo ndi chisankho chabwino cha opanga zakudya akufuna kuti achepetse zachilengedwe. Zipangizozi ndi zolimba, zolimba, komanso zosakwanira, zimapangitsa kuti akhale ndi chisankho chabwino chokhacho.
Matumba a mapepala
Matumba a pepala ndi njira yochezeka komanso yosasunthika ya kayendedwe ka kayendedwe. Amapangidwa ndi zothandizira zapamwamba ndipo amatha kubwezeretsedwanso, kuphatikizidwa kapena kugwiritsidwanso ntchito. Matumba a pepala ndi opepuka, osavuta kuthana ndi mtengo wokwera mtengo. Ndiabwino kuti anyamule zodyera zouma monga tchipisi, popcorn ndi mtedza.
Matumba a pepala akupezeka m'mitundu yosiyanasiyana, kuphatikiza:
Matumba a Kraft:Wopangidwa ndi zamkati kapena kuphatikizidwa, matumba awa ndi olimba, olimba, komanso amakhala ndi mawonekedwe achilengedwe.
Matumba oyera:Zopangidwa ndi zamkati zophatikizidwa, matumba awa ndi osalala, oyera, ndikukhala ndi mawonekedwe owala.
Matumba a Mapepala a Greeproof:Matumba awa ali ndi mawonekedwe osanjikiza mafuta ambiri, ndikuwapangitsa kukhala oyenera kuti akwaniritse zakudya zowala.
Matumba a pepala amatha kusindikizidwa ndi mapangidwe azachilengedwe, Logos, ndi chizindikiro, zimapangitsa kuti akhale chida chabwino chotsatsa makampani amakampani. Amathanso kukhala ndi zinthu monga Retable Squable, machesi osowa, ndi mawindo owonjezera kuti azitha kusintha komanso kuwoneka.
Komabe, matumba apepala ali ndi malire. Sali oyenera kunyamula zodyera kapena zonyowa chifukwa amatha kung'amba kapena kusanduka. Amakhalanso ndi chinyezi chotsutsana ndi chinyezi, mpweya, ndi kuwala, zomwe zingakhudze moyo wa alumali ndi mtundu wa zokhwasula.
Ponseponse, matumba a mapepala ndi njira yokhazikika komanso yosiyanasiyana yopanga zakudya, makamaka zazikazi zouma. Amapereka mawonekedwe achilengedwe komanso kumva bwino, ndi okwera mtengo, ndipo amatha kusinthidwa kuti akwaniritse zosowa zenizeni komanso zotsatsa.
