Izindaba - Ungakhetha kanjani impahla yezikhwama zokupakisha?

1. Buyisa isikhwama sokupakisha

Izidingo zokupakisha: Isetshenziselwaukupakisha inyama, izinkukhu, njll., ukupakishwa kuyadingeka ukuze kube nezindawo ezinhle zokuvimbela, ukumelana nezimbobo zamathambo, futhi kufakwe inzalo ngaphansi kwezimo zokupheka ngaphandle kokuphuka, ukuqhekeka, ukuncipha, nokungabi naphunga.

Isakhiwo sedizayini:Uhlobo olubonisa ngale: BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPPPET/PVDC/CPP, GL-PET/BOPA/CPP Aluminium uhlobo lwefoil: PET/AL/CPP, PA/AL/ CPPPET/ PA/AL/CPP,PET/AL/PA/CPP

Isizathu sokuklama: I-PET: ukumelana nokushisa okuphezulu, ukuqina okuhle, ukuphrinta okuhle namandla aphezulu.I-PA: Ukumelana nokushisa okuphezulu, amandla aphezulu, ukuguquguquka, izakhiwo ezinhle zokuvimbela, nokumelana nokubhoboza.AL: Izakhiwo ezingcono kakhulu zokuvimbela, ukumelana nezinga lokushisa eliphezulu.I-CPP: Ibanga lokupheka elinokushisa okuphezulu elivaleka kahle ukushisa, elingenabuthi futhi alinaphunga.I-PVDC: impahla yokuvimbela ukumelana nokushisa okuphezulu.I-GL-PET: Ifilimu ehwamukile ye-Ceramic, enezindawo ezinhle zokuthibela futhi esobala kuma-microwaves.Khetha isakhiwo esifanele semikhiqizo ethile.Izikhwama ezisobala zisetshenziswa kakhulu ukupheka, futhiIzikhwama ze-AL foilingasetshenziswa ekuphekeni izinga lokushisa eliphezulu kakhulu.

2. Isikhwama somshini wokuhlanza owuketshezi

Izidingo zokupakisha:amandla aphezulu, ukumelana nomthelela, ukumelana nokuqhuma, izakhiwo ezinhle zokuvimbela, ukuqina okuhle, ukwazi ukuma uqonde, ukumelana nokuqhekeka kwengcindezi, nokuvala uphawu okuhle.

Isakhiwo sedizayini:①Asukume isikhwama: BOPA/LLDPE;Ngezansi: BOPA/LLDPE.②Asukume isikhwama: I-BOPA/i-BOPP eqinisiwe/i-LLDPE;phansi: BOPA/LLDPE.③Asukume isikhwama: I-PET/BOPA/i-BOPP/LLDPE eqinisiwe;phansi: BOPA/LLDPE.

Izizathu zokuklama:Isakhiwo esingenhla sinezakhiwo ezinhle zokuvimbela, impahla iqinile kakhulu, futhi ifanele izikhwama zokupakisha ezinezinhlangothi ezintathu.Okuphansi kuyaguquguquka futhi kufanelekile ukucutshungulwa.Isendlalelo sangaphakathi siguquliwe i-PE, enokubekwa uphawu okuhle nokumelana nokungcola.I-BOPP eqinisiwe inyusa amandla emishini yezinto futhi ithuthukisa izakhiwo zokuthibela zezinto.I-PET ithuthukisa ukumelana namanzi namandla emishini yezinto.

3.Ukupakisha oyinyumba

Izidingo zokupakisha zezinto zokumboza:Kufanele zibe yinyumba ngesikhathi sokupakishwa nokusetshenziswa.

Isakhiwo sedizayini:i-coating/AL/peel layer/MDPE/LDPE/EVA/peel layer/PET.

Isizathu sokuklama:I-PET iyifilimu yokuvikela eyinyumba engaxetshulwa.Uma ungena endaweni yokupakisha eyinyumba, hlikihla i-PET ukuze uveze indawo eyinyumba.Isendlalelo se-AL foil peel-off siyambulwa lapho amakhasimende ephuza.Punch imbobo yokuphuza kusendlalelo se-PE kusengaphambili, futhi imbobo yokuphuza izodalulwa lapho i-AL foil ihlutshiwe.I-AL foil isetshenziselwa umgoqo ophezulu.I-MDPE inokuqina okungcono nokunamathela okungcono okushisayo nge-AL foil.I-LDPE ishibhile.Okuqukethwe kwe-VA kwe-EVA yangaphakathi ngu-7%.I-VA>14% ayikuvumeli ukuthintana okuqondile nokudla.Ukuvalwa kokushisa okuphansi kwe-EVA kunokumelana okuhle nokungcoliswa kophawu.

Isakhiwo sedizayini:I-BOPA/VMPET/S-CPP

Isizathu sokuklama: I-BOPA inokuguquguquka okuhle, ukumelana nokubhoboza, amandla aphezulu nokuphrinta okuhle.I-VMPET inamandla aphezulu kanye nezakhiwo ezinhle zokuvimbela, futhi ingasebenzisa izinto zokunamathela ezikhulayo.I-S-CPP ihlinzeka ngokuvaleka kokushisa, izakhiwo zokuvimbela kanye nokumelana nokugqwala, futhi isebenzisa i-ternary copolymer PP.Noma sebenzisa i-CPP enezingqimba eziningi equkethe izendlalelo ze-EVOH ne-PA enezithiyo eziphezulu.

5. Izikhwama zokupakisha ezisindayo

Izidingo zokupakisha: Ukupakisha okusindayo kusetshenziselwa ukupakisha imikhiqizo yezolimo efanairayisi, ubhontshisi, imikhiqizo yamakhemikhali (njengama-fertilizer), njll. Izidingo eziyinhloko zingamandla amahle kanye nokuqina kanye nezakhiwo ezidingekayo zokuvimbela.

Isakhiwo sedizayini:Indwangu ye-PE/plastiki/i-PP, i-PE/iphepha/i-PE/indwangu yepulasitiki/i-PE, i-PE/PE

Isizathu sokuklama:I-PE inikeza ukubekwa uphawu, ukuguquguquka okuhle, ukumelana nokwehla, namandla aphezulu ezindwangu zepulasitiki.
