Zolemba za mawa ndizanzeru komanso zolunjika kumagulu ndi zinthu zina zomwe mukufuna."Izi ndi zomwe mabungwe amakampani opanga zitsulo, migodi, mankhwala ndi mphamvu, monga IG metall, IG Bergbau, Chemie ndi Energie, amatchula mu lipoti lamakampani onyamula katundu, ndipo ndizotsimikizika kuti sipadzakhalanso china chilichonse chotsatira. zaka zingapo.kusintha kulikonse.
Mapaketi osinthika osinthika, nthawi yayitali ya alumali komanso kuyika kosavuta kutsegula ndi mitu yofunikira yomwe ikuyendetsa kukula kwamakampani.Kukula uku kwa msika wonyamula katundu kumayendetsedwa makamaka ndi msika waku Asia, komanso kumayendetsedwa ndi misika ya Kum'mawa ndi Kumadzulo kwa Europe.Kuphatikiza apo, mitu yachitukuko ndi chitukuko chokhazikika ikulimbikitsanso kukula kwa msika wamapaketi.
Kupaka kumafunika pafupifupi m'mafakitale onse.Ngakhale kuti nthawi zambiri amagwiritsidwa ntchito kuteteza malonda ndikuthandizira kusungirako ndi mayendedwe, kulongedza kumathandizanso kusiyanitsa malonda ndikupanga malo ogulitsa.
Chikwama chopakira chakudyamafakitale nthawi zonse wakhala msika wofunikira womwe makampani onyamula katundu amakhudzidwa kwambiri nawo.Ku Europe kokha, pafupifupi 60% yazakudya zimawonongeka chifukwa cha kuwonongeka, chiwerengero chomwe chingakhale chotsika kwambiri ndi ma CD oyenera.M’lingaliro lina, kutetezedwa kwa mankhwalawo ndiko kuteteza nyengo chifukwa, pofuna kubwezeretsanso chakudya chimene chinawonongeka chifukwa cha chitetezo chosayenera, chakudya chatsopano chiyenera kupangidwa, ndipo zotsatira za carbon footprint nthawi zambiri zimakhala zazikulu kuposa zomwe zimapangidwira. ndikulongedza bwino.Chifukwa chake, kupewa chakudya chowonongeka chokhala ndi gawo lalikulu la kaboni.
Mwachidule, makampani onyamula katundu apitiliza kuyenda bwino, koma akuyenera kukwaniritsa zosowa za msika ndi njira zatsopano zothetsera.
Mosakayikira, zonyamula katundu ndizosiyana kwambiri, ndipo nkhani imodzi siyingafotokoze zonse, kotero mutu umodzi wokha ndi zitsanzo zina zimasankhidwa apa.
Thanzi ndilokhazikika nthawi zonse
Mutu wobwerezabwereza wokhudzana ndi kuyika kwa pulasitiki ndi thanzi.Ndizosaneneka kuti zotengera zilizonse zoteteza zimapindulitsa thanzi la ogula popatula chakudya kuzinthu zosiyanasiyana zakunja.M'makampani a zakumwa makamaka, kuwonjezera kwa zinthu zolimbikitsa thanzi ku zakumwa ndizomwe zikukula, kotero chitetezo chapadera chonyamula zakumwa chimafunikira pazakumwa zotere, monga zakumwa zamadzimadzi zomwe zili ndi vitamini wambiri, komanso zakumwa zamasewera ndi zakumwa zolimbitsa thupi ndi wapadera zowonjezera zakudya zakumwa.KHS Plasmax, yochokera ku Hamburg, Germany, yapanga ukadaulo wa Plasmax kuti zakumwa izi zikhale zatsopano mubotolo kwa nthawi yayitali.Mwachindunji, mu njira yotsika kwambiri ya plasma, wosanjikiza wa silicon oxide (ndiko kuti, galasi) wa nanometers pafupifupi 50 amayikidwa pakhoma lamkati laPET botolo, kotero kuti chakumwacho chitetezedwe kudziko lakunja, kotero chikhoza kusungidwa motalika , mavitamini ndi zowonjezera sizidzatayika.Mosiyana ndi ukadaulo wamabotolo amitundu ingapo, ukadaulo wa Plasmax ndiwovuta pang'ono, koma umabweretsa mtengo wotsika kwambiri pabotolo lililonse.Ubwino waukulu wa njira ya Plasmax ndikuti mabotolo amatha kubwezeretsedwanso.
Zakumwa zopatsa thanzi zokhala ndi tinthu tambirimbiri ndi njira inanso yopangira zakumwa, monga madzi okhala ndi zidutswa za aloe vera, mkaka ndi yogati wokhala ndi zipatso.Chakumwachi chimafuna osati mawonekedwe ofananira a botolo, komanso ukadaulo wodzaza womwe umatha kuyeza tinthu tolimba mwaukhondo komanso ndendende.Monga m'modzi mwa akatswiri opanga makina odziwa bwino ntchitoyi, Krones, yomwe ili ku Neutraubling, Germany, ikupereka chizindikiro cha Dosaflex chizindikiro chapadera cha metering, chomwe chimatha kuyeza 3mm x 3mm x 3mm ndi kulondola kwa mita ± 0.3% The lumpy particles amayesedwa.
Komabe, chifukwa cha moyo wa alumali wochepa wa zakumwa zamkaka, Holland Colours NV, Apeldoorn, The Netherlands, yakhazikitsa chowonjezera chake cholimba cha Holcomer III, chomwe chimapereka chitetezo cha 100% ku mazira a UV ndi mpaka 99% Chitetezo ku kuwala kowonekera, motero kulola kupanga njira zopangira ma PET monolayer mkaka wopanda pasteurized.Ubwino wodziwikiratu wa yankho ili ndi kapangidwe kake kagawo kakang'ono, komwe kumapangitsa kuti zikhale zosavuta kuzibwezeretsanso kuposa zotengera zamitundu yambiri.
Wopepuka ndiye mutu wamuyaya
Ndi njira iliyonse yopangira ma phukusi, kulemera kumakhala koyang'ana nthawi zonse, ndipo zaka zingapo zapitazi, malingaliro ndi mayankho ochepetsa kulemera adawonekera.Pakati pa 1991 ndi 2013, kulemera kwake kwapang'onopang'ono kwachepetsedwa ndi 25% chifukwa cha mapangidwe atsopano ndi kuchepetsa makulidwe a khoma.Ngakhale kuyembekezera kukulirakulira kwa magwiridwe antchito, mu 2013 mokha, matani 1 miliyoni apulasitiki adapulumutsidwa padziko lonse lapansi kuchokera pakusunga zolemetsa.Kutenga mabotolo a PET mwachitsanzo, sikuti makulidwe a khoma adachepetsedwa, koma mapangidwe apansi adakonzedwanso, ndipo mapangidwe atsopano ozungulira okha amapulumutsa 2g ya pulasitiki pa botolo.Pofuna kukhathamiritsa pansi pa botolo, Creative Packaging Solutions Ltd., yomwe ili ku Balcova-Izmir, Turkey, yapanga njira yake ya Mint-Tec, yomwe, itatha kupanga preform, pistoni imalowa mu botolo popanda kukhudza khosi la botolo.Pansi kumabweretsa mawonekedwe omwe mukufuna.
Zapangidwa kuti zigwiritsidwenso ntchito kuyambira pachiyambi
Zomwe zimapangidwira zomwe zimamwa zakumwa monga chitsanzo zimagwiranso ntchito pafupifupi madera ena onse ogulitsa zakudya, kumene kuchepetsa kulemera nthawi zonse kumabwera poyamba.Izi zili choncho chifukwa kuchepetsa kulemera kumagwirizana ndi kusunga zinthu ndi kuchepetsa mtengo, koma si zokhazo.Chifukwa, ndipo chofunika kwambiri, ndi chakuti okonza malamulo ndi ogula akufunafuna kwambiri "chitetezo chazinthu", chomwe chikugwirizana kwambiri ndi lingaliro la kubwezeredwa kwa ma CD.Ku Germany, komwe pafupifupi zotengera zonse zapakhomo zimatha kugwiritsidwanso ntchito, zoposera theka (56%) zimasinthidwanso m'malo motenthedwa, kuchokera pa 3% pafupifupi zaka 20 zapitazo.Pachifukwa ichi, mabotolo a PET amakhala ndi chiwongola dzanja chochulukirapo, pomwe 98% yazinthuzo zimabwezedwa ndikubwezeretsedwanso pakupanga.Ndiye kuti, botolo lililonse latsopano lomwe limapangidwa lero lili ndi pafupifupi 25% ya zinthu zobwezerezedwanso.
Kugwiritsiridwa ntchito kwa zosungiramo zinyalala kumatha kupititsidwa patsogolo ngati zotengerazo zidapangidwa kuti zigwiritsidwenso ntchito kuyambira pachiyambi.Monga purosesa ya polyolefin, Dr. Michael Scriba, Managing Director wa mtm plastics ku Niedergebra, Germany, akudziwa bwino za vutoli.M'malingaliro ake, mapulasitiki opangidwa bwino ayenera kugwiritsidwa ntchito ngati kuli kotheka, osati "mapepala-pulasitiki" opangidwa ndi mapepala, osati polyolefins yakuda kapena calcium carbonate.Komanso, PET iyenera kukondedwa ndi mabotolo m'malo mwa ma tray ozama kwambiri.
