Ngokwandiswa kolwazi ngokusingqongileyo, imfuno yabantu yezixhobo ezihambelana nokusingqongileyo kunye neemveliso zabo nazo ziyanda. Izinto ezivundisiweyo zePLA kunye neengxowa zokupakisha ezivundisiweyo zePLA ngokuthe ngcembe zisetyenziswa ngokubanzi kwintengiso.
I-Polylactic acid, ekwaziwa njenge-PLA (i-Polylactic Acid), i-polymer efunyenwe nge-polymerizing lactic acid njengeyona nto iphambili ekrwada. Umthombo wempahla ekrwada yanele ubukhulu becala ukusuka kumbona, icassava, njl.njl..Inkqubo yokuvelisa ye-PLA ayingcolisi, kwaye imveliso inokuthi ihlaziywe kwaye isetyenziswe kwakhona kwindalo.
Izinto ezilungileyo zePLA
I-1.Biodegradability: Emva kokuba i-PLA ilahliwe, inokutshatyalaliswa ngokupheleleyo emanzini kunye ne-carbon dioxide phantsi kweemeko ezithile, kwaye iphinde ingene kwi-circulation yendalo, ukuphepha ukungcola kwexesha elide kwindalo ebangelwa iiplastiki zendabuko.
2. Imithombo ehlaziyekayo: I-PLA ipholima ikakhulu kwi-lactic acid ekhutshwe kwi-corn starch, iswekile kunye nezinye izityalo, ezizizixhobo ezivuselelekayo, kunye nokunciphisa ukuxhomekeka kwimithombo yepetroleum.
3. Inomoya omhle wokungena komoya, i-oxygen permeability kunye ne-carbon dioxide permeability, nayo inepropati yokuhlukanisa iphunga. Iintsholongwane kunye nokubumba zivame ukunamathela kumphezulu weeplastiki ze-biodegradable, ngoko kukho iinkxalabo malunga nokhuseleko kunye nococeko. Nangona kunjalo, i-PLA kuphela kweplastiki enokubola enezinto ezintle zokulwa ne-bacteria kunye ne-anti-mold.
Indlela yokuthotywa kwePLA
I-1.Hydrolysis: Iqela le-ester lekhonkco eliphambili liphukile, ngaloo ndlela linciphisa ubunzima be-molecular.
I-2.I-Thermal decomposition: into eyinkimbinkimbi ekhokelela ekuveleni kwee-compounds ezahlukeneyo, ezifana ne-molecules ezilula kunye ne-linear kunye ne-cyclic oligomers ezinobunzima obuhlukeneyo be-molecular, kunye ne-lactide.
3.Ukuchithwa kwefoto: Imitha ye-ultraviolet inokubangela ukuthotywa. Le yeyona nto iphambili ekuvezweni kwePLA ekukhanyeni kwelanga kwiiplastiki, kwizikhongozeli zokupakisha, kunye nokusetyenziswa kwefilimu.
Ukusetyenziswa kwePLA kwindawo yokupakisha
Izinto ze-PLA zisetyenziswa kwiinkalo ezininzi. Kwishishini lokupakisha, ifilimu ye-PLA isetyenziswa kakhulu kwipakethe yangaphandle yokutya, isiselo kunye neziyobisi ukuze zithathe indawo yokupakishwa kweplastiki yendabuko, ukuze kufezekiswe injongo yokukhuselwa kwendalo kunye nokuzinza.
I-PACK MIC igxile ekuveliseni iingxowa ezilungiselelweyo ezinokuphinda zisetyenziswe kunye nezivundisiweyo.
Uhlobo lwebhegi: ibhegi enamacala amathathu etywina, isingxobo sokuma, ibhegi ye-zipper yokuma, ibhegi esezantsi esezantsi
Ubume bezinto eziphathekayo: iphepha le-kraft / i-PLA
Ubungakanani: bungenziwa ngokwezifiso
Ukushicilela: CMYK + Spot umbala (nceda unikeze umzobo woyilo, siya kuprinta ngokomzobo woyilo)
Izixhobo: IZipper / iTin Tie / iValve / Umngxuma ojingayo / inotshi yokukrazula / iMat okanye ekhazimlayo njl.
