Iyo yekunze dhizaini inobvumira kugadziridza, sekudhinda iyo chaiyo yekofi mukati, nepo mukati memukati inoshanda sechivharo.
Aluminium foil haina huremu, yakachengeteka kushandisa pachikafu, haizongoora, uye inodzivirira kuchiedza nehunyoro.
Asi pane zvirambidzo zvakati wandei kana uchishandisa foil-lined kofi mabhegi.Sezvo ichicherwa, aruminiyamu inoonekwa sechinhu chidiki chinozopedzisira chazvipedza pachako, zvichikwidza mutengo wekushandisa.
Uyezve, kana yakapetwa kana kupetwa, foil yealuminium inogona dzimwe nguva kurasikirwa nechimiro chayo kana kuwana microscopic punctures.Pakurongedza kofi mufoiri, vharuvhu ye degassing inofanira kuiswa pabhegi nekuti foil inogona kunge isina mhepo.
Kuchengetedza kunaka kwekofi yakagochwa uye kudzivirira kurongedza kubva pakuputika, kabhoni dhaikisaidhi inoburitswa semarara ekofi yakagochwa inofanira kubvumidzwa kubuda.
Ko mabhegi ekofi anoda kuiswa nefoil here?
Iko kudikanwa kwekurongedza kuchinjika kuchawedzera pamwe nehuwandu hwepasirese.
Nekuda kwekushandiswa kwayo uye kuwanikwa, inoshanduka kofi kurongedza inotarisirwawo kuona kuwedzera kwekuda.
Flexible packaging zvakare ine hushamwari kwezvakatipoteredza pane kukwikwidza sarudzo, ine yekurongedza-kune-chigadzirwa reshiyo inodzika kashanu kusvika kagumi.
Anopfuura mamirioni makumi maviri ematani emidziyo yekurongedzera anogona kuchengetwa muEU chete kana mamwe mafemu akatamira kune anochinjika kurongedza.
Saka, vanogocha vanopa kurongedza zvine hushamwari kwezvakatipoteredza vanogona kunyengetedza vatengi kuti vade chigadzirwa chavo pane vanokwikwidza mabhurendi.Nekudaro, ongororo ichangoburwa yeGreenpeace yakawana kuti panzvimbo yekuti zvishandiswezve, zvinhu zvizhinji zvinopiswa kana kusiiwa.
Izvi zvinoreva kuti vanogocha vanofanira kushandisa sepakurongedza kwakasimba sezvavanokwanisa.Kunyange zvazvo foil iri chinhu chinobatsira pakugadzira mabhegi ekofi, pane zvipingamupinyi zvine vanogocha vachitsvaga dzimwe nzira.
Vazhinji vanogocha vanosarudza kushandisa mukati memukati mesimbi yePET uye yekunze layer yakagadzirwa nepolyethylene (PE).Zvisinei, chinonamira chinowanzoshandiswa kusunga zvinhu izvi, zvichiita kuti zviparadzaniswe.
Sezvo aruminiyamu yakashandiswa muchimiro ichi haisati yagona kugadzikiswa kana kudzoreredzwa, inowanzoguma yava kupiswa.
A polylactic acid (PLA) liner inogona kunge iri sarudzo iri nani kune zvakatipoteredza.Iyi bioplastic inogadzirwa kubva kune zvinogonekazve sechibage nechibage uye haina muchetura.
Pamusoro pezvo, PLA inogona kuora munzvimbo yekutengesa kompositi uye inopa chipingamupinyi chakasimba kurwisa tembiricha yepamusoro, kunyorova, uye hunyoro.Upenyu hwebhegi rekofi hunogona kuwedzerwa kusvika kune gore apo PLA inoshandiswa kurongedza bhegi.
kuchengetedza kuchengetedzwa kwekofi kurongedza
Kunyange zvazvo mabhegi ekofi ane foil angave ane zvakanakira, vanogocha vane dzimwe sarudzo dzakasiyana-siyana dzinogona kubatsira kuchengetedza hutsva.
Pane sarudzo dzakati kuti dzine hushamwari kwezvakatipoteredza dziripo, chero bedzi vanogocha vachizivisa vatengi vavo kuti vangazvirasa sei nemazvo.Semuyenzaniso, vanogocha kofi vanosarudza PLA-lined packaging vanofanira kuraira vatengi kuti vaise bhegi risina chinhu mubhini rakakodzera recycling kana bhini nhamba.
Vanogocha vangangoda kuunganidza mabhegi ekofi akashandiswa ivo pachavo kana nharaunda yekudzokorodza nzvimbo isingakwanise kubata zvinhu izvi.
Vatengi vanogona kugashira kofi yakachipa kubva kune vanogocha mukuchinjana nekudzorera isina chinhu kofi package.Iyo yekugocha inogona kutumira mabhegi akashandiswa kumashure kumugadziri kuti ashandiswezve kana kuraswa zvisina njodzi.
Pamusoro pezvo, kuita izvi kunovimbisa kuti kunze kwechigadzirwa kurongedza uye kurongedza zvinhu, senge zip uye degassing mavharuvhu, zvakapatsanurwa kubva uye kugadziriswa.
Vatengi vekofi vanhasi vane zvimwe zvavanoda, uye kurongedza kunofanirwa kuve kwakasimba zvakare.Vatengi vanoda nzira yekuchengetedza kofi yavo ine zvishoma zvingangoitika kwezvakatipoteredza, izvo zvinofanirwa kupa vanogocha.
PaCYANPAK, tinopa sarudzo ye100 muzana inogadziriswazve kofi yekurongedza zvigadziriso zvinogadzirwa kubva kune zvinogonekazve senge Kraft bepa, bepa remupunga, kana akawanda-layer LDPE kurongedza ine eco-inoshamwaridzika PLA lining, izvo zvese zvinoderedza marara uye kutsigira hupfumi hwakatenderera.
Uyezve, tinopa vanogocha rusununguko rwese rwekugadzira nekuvarega vachigadzira mabhegi avo ekofi.
