Pulasitiki Packaging
Matumba opaka pulasitiki ndi njira yotchuka yopangira zokhwasula-khwasula chifukwa cha kulimba, kusinthasintha, komanso mtengo wotsika. Komabe, sizinthu zonse zapulasitiki zomwe zili zoyenera kunyamula zokhwasula-khwasula. Nazi zina mwazinthu zodziwika bwino za pulasitiki zomwe zimagwiritsidwa ntchito popanga matumba onyamula zoziziritsa kukhosi:
Polyethylene (PE)
Polyethylene ndi matumba apulasitiki omwe amagwiritsidwa ntchito kwambiri. Ndizinthu zopepuka komanso zosinthika zomwe zimatha kupangidwa mosavuta mumitundu ndi makulidwe osiyanasiyana. Matumba a PE amalimbananso ndi chinyezi ndipo amatha kusunga zokhwasula-khwasula kwa nthawi yaitali. Komabe, matumba a PE sali oyenera zakudya zopsereza zotentha chifukwa zimatha kusungunuka kutentha kwambiri.
Polypropylene (PP)
Polypropylene ndi pulasitiki yolimba komanso yolimba yomwe imagwiritsidwa ntchito popanga matumba onyamula zokhwasula-khwasula. Matumba a PP amalimbana ndi mafuta ndi mafuta, kuwapangitsa kukhala abwino kulongedza zokhwasula-khwasula monga tchipisi ndi ma popcorn. Matumba a PP nawonso ndi otetezedwa mu microwave, zomwe zimawapangitsa kukhala chisankho chodziwika bwino pakuyika zokhwasula-khwasula.
Polyvinyl Chloride (PVC)
Polyvinyl Chloride, yomwe imadziwikanso kuti PVC, ndi zinthu zapulasitiki zomwe zimagwiritsidwa ntchito popanga matumba onyamula zokhwasula-khwasula. Matumba a PVC ndi osinthika komanso olimba, ndipo amatha kusindikizidwa mosavuta ndi mapangidwe okongola. Komabe, matumba a PVC sali abwino pazakudya zopsereza chifukwa amatha kutulutsa mankhwala owopsa akatenthedwa.
Mwachidule, matumba apulasitiki oyikamo ndi chisankho chodziwika bwino pakuyika zokhwasula-khwasula chifukwa cha kulimba kwawo, kusinthasintha, komanso mtengo wotsika. Komabe, ndikofunikira kusankha zinthu zapulasitiki zoyenera zopangira zokhwasula-khwasula kuti zitsimikizire chitetezo ndi mtundu wa zokhwasula-khwasula. PE, PP ndi PVC ndi zina mwazinthu zapulasitiki zomwe zimagwiritsidwa ntchito popanga matumba onyamula zokhwasula-khwasula, chilichonse chili ndi zabwino zake komanso zolephera zake.
Matumba Oyikiramo Biodegradable
Matumba oyika zinthu owonongeka ndi njira yabwino kwambiri yopangira zonyamula zoziziritsa kukhosi. Matumbawa amapangidwa kuti awonongeke mwachibadwa pakapita nthawi, kuchepetsa kuchuluka kwa zinyalala zomwe zimatha kutayira. Mitundu iwiri yodziwika bwino ya zinthu zomwe zimatha kuwonongeka zomwe zimagwiritsidwa ntchito m'matumba onyamula zokhwasula-khwasula ndi Polylactic Acid (PLA) ndi Polyhydroxyalkanoates (PHA).
Polylactic Acid (PLA)
Polylactic Acid (PLA) ndi polima wopangidwa ndi zinthu zongowonjezedwanso monga chimanga, nzimbe, ndi chinangwa. PLA yayamba kutchuka m'zaka zaposachedwa chifukwa cha kuthekera kwake kuwonongeka mwachilengedwe m'chilengedwe. Komanso ndi manyowa, kutanthauza kuti akhoza kugawidwa kukhala organic zinthu zomwe zingagwiritsidwe ntchito kukulitsa nthaka.
PLA imagwiritsidwa ntchito kwambiri m'matumba onyamula zokhwasula-khwasula chifukwa ndi yamphamvu komanso yolimba, koma imatha kuwonongeka. Ilinso ndi mawonekedwe otsika a carbon, ndikupangitsa kuti ikhale njira yabwino yosamalira zachilengedwe.
Polyhydroxyalkanoates (PHA)
Polyhydroxyalkanoates (PHA) ndi mtundu wina wa polima wowonongeka womwe ungagwiritsidwe ntchito m'matumba onyamula zokhwasula-khwasula. PHA imapangidwa ndi mabakiteriya ndipo imatha kuwonongeka m'madera osiyanasiyana, kuphatikizapo malo apanyanja.
PHA ndi zinthu zosunthika zomwe zitha kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza zonyamula zokhwasula-khwasula. Ndi yamphamvu komanso yolimba, komanso imatha kuwonongeka ndi biodegradable, kupangitsa kuti ikhale yabwino kwa opanga zokhwasula-khwasula zachilengedwe.
Pomaliza, matumba onyamula zinthu zoziziritsa kukhosi monga PLA ndi PHA ndi chisankho chabwino kwambiri kwa opanga zokhwasula-khwasula omwe akufuna kuchepetsa kuwononga chilengedwe. Zidazi ndi zamphamvu, zolimba, komanso zowola, zomwe zimapangitsa kuti zikhale zosankha zabwino zopangira zokhwasula-khwasula.
Mapepala Packaging Matumba
Matumba onyamula mapepala ndi njira yabwino komanso yosasunthika pakuyika zokhwasula-khwasula. Amapangidwa ndi zinthu zongowonjezedwanso ndipo amatha kubwezeredwa, kupangidwanso ndi kompositi kapena kugwiritsidwanso ntchito. Matumba amapepala nawonso ndi opepuka, osavuta kunyamula komanso okwera mtengo. Ndi abwino kulongedza zokhwasula-khwasula zowuma monga tchipisi, ma popcorn ndi mtedza.
Matumba onyamula mapepala amapezeka m'mitundu yosiyanasiyana, kuphatikiza:
Matumba a Kraft Paper:opangidwa ndi zamkati zosapangidwa ndi bleached kapena bleached, matumbawa ndi amphamvu, okhazikika, ndipo amakhala ndi maonekedwe achilengedwe.
Mapepala Oyera:opangidwa ndi zamkati zothira, matumbawa ndi osalala, oyera, komanso owoneka bwino.
Mapepala a Greaseproof Paper:matumba amenewa yokutidwa ndi wosanjikiza zinthu zosagwira mafuta, kuwapanga kukhala oyenera kulongedza zokhwasula-khwasula mafuta.
Matumba amapepala amatha kusindikizidwa ndi mapangidwe ake, ma logo, ndi chizindikiro, kuwapanga kukhala chida chabwino kwambiri chotsatsa makampani opanga zokhwasula-khwasula. Atha kukhalanso ndi zinthu monga zotsekeranso zotsekera, ma notche ong'ambika, ndi mazenera owoneka bwino kuti aziwoneka bwino komanso aziwoneka bwino.
Komabe, matumba a mapepala ali ndi malire. Sizoyenera kulongedza zokhwasula-khwasula zonyowa kapena zonyowa chifukwa zimatha kung'ambika kapena kunjenjemera. Amakhalanso ndi chotchinga chochepa kutsutsana ndi chinyezi, mpweya, ndi kuwala, zomwe zingakhudze moyo wa alumali ndi ubwino wa zokhwasula-khwasula.
Ponseponse, matumba oyika mapepala ndi njira yokhazikika komanso yosunthika pakuyika zokhwasula-khwasula, makamaka pazakudya zowuma. Amapereka mawonekedwe achilengedwe ndi mawonekedwe, ndi otsika mtengo, ndipo amatha kusinthidwa kuti akwaniritse zosowa zenizeni zamalonda ndi malonda.
