Iindaba - Indlela yokukhetha izinto eziphathekayo zeengxowa zokupakisha?

1. Ibhegi yokupakisha yokubuyisela

Iimfuno zokupakisha: Isetyenziselwaukupakisha inyama, iinkukhu, njl., ukupakishwa kuyadingeka ukuba kube neendawo ezintle zokuthintela, ukuchasana nemingxuma yamathambo, kunye ne-sterilized phantsi kweemeko zokupheka ngaphandle kokuphulwa, ukuqhekeka, ukuncipha, kunye nokungabi navumba.

Ubume boyilo:Uhlobo olungafihliyo: BOPA/CPP, PET/CPP, PET/BOPA/CPP,BOPA/PVDC/CPPPET/PVDC/CPP, GL-PET/BOPA/CPP Aluminiyam uhlobo lwefoil: PET/AL/CPP,PA/AL/ CPPPET/ PA/AL/CPP,PET/AL/PA/CPP

Isizathu soyilo: I-PET: ukumelana nobushushu obuphezulu, ukuqina okulungileyo, ukuprintwa kakuhle kunye namandla aphezulu.I-PA: Ukumelana nobushushu obuphezulu, ukomelela okuphezulu, ukuguquguquka, iipropathi ezilungileyo zesithintelo, kunye nokumelana nokugqobhoza.AL: Iipropati ezizezona zithintelo, ukumelana nobushushu obuphezulu.I-CPP: Linqanaba lokupheka lobushushu obuphezulu kunye nokutywinwa kobushushu obulungileyo, obungenabungozi kwaye bungenavumba.I-PVDC: Isixhobo sokuthintela ubushushu obuphezulu.I-GL-PET: Ifilimu engumphunga yeCeramic, eneempawu ezintle zokuthintelwa kunye nokungafihli kwii-microwaves.Khetha isakhiwo esifanelekileyo kwiimveliso ezithile.Iingxowa ezicacileyo zisetyenziselwa ukupheka, kwayeIingxowa ze-AL foilingasetyenziselwa ukupheka kobushushu obuphezulu.

2. Isicoci solwelo phakama sisingxobo

Iimfuno zokupakisha:amandla aphezulu, ukuchasa impembelelo, ukuchasana nokugqabhuka, iipropathi ezilungileyo zomqobo, ukuqina okuhle, ukukwazi ukuma nkqo, ukuchasana nokuqhekeka koxinzelelo, kunye nokutywinwa okuhle.

Ubume boyilo:①Phakama isingxobo: BOPA/LLDPE;Ezantsi: BOPA/LLDPE.②Phakama isingxobo: I-BOPA/i-BOPP eqinisiweyo/i-LLDPE;ngezantsi: BOPA/LLDPE.③Phakama isingxobo: PET/BOPA/i-BOPP eqinisiweyo/LLDPE;ngezantsi: BOPA/LLDPE.

Izizathu zoyilo:Isakhiwo esingentla sineempawu ezintle zomqobo, izinto eziphathekayo ziqinile, kwaye zifanelekile kwiingxowa zokupakisha ezintathu-dimensional.Umzantsi uguquguquka kwaye ufanelekile ukuqhutyelwa phambili.Uluhlu lwangaphakathi luguquliwe i-PE, enokutywinwa kakuhle kunye nokuchasana nongcoliseko.I-BOPP eyomeleziweyo yokwandisa amandla omatshini wezinto eziphathekayo kunye nokwandisa iimpawu zomqobo zezinto.I-PET iphucula ukuxhathisa kwamanzi kunye namandla omatshini wezinto eziphathekayo.

3.Ukupakishwa okunyumba

Iimfuno zokupakisha zezixhobo zokugquma:Kufuneka zingabi ntsholongwane ngexesha lokupakishwa kunye nokusetyenziswa.

Ubume boyilo:i-coating/AL/peel layer/MDPE/LDPE/EVA/peel layer/PET.

Isizathu soyilo:I-PET yifilimu ekhuselayo engenazintsholongwane enokuxotyulwa.Xa ungena kwindawo yokupakisha engenazintsholongwane, cofa i-PET ukuze uveze umphezulu oyinyumba.I-AL foil peel-off layer ityhilwa xa abathengi besela.Gcoba umngxuma wokusela kwi-PE layer kwangaphambili, kwaye umngxuma wokusela uya kubonakaliswa xa i-AL foil ihlanjululwa.I-AL foil isetyenziselwa umqobo ophezulu.I-MDPE inobulukhuni obungcono kunye nokunamathela okungcono kwe-thermal nge-AL foil.I-LDPE itshiphu.Umxholo we-VA we-EVA yangaphakathi yi-7%.I-VA> 14% ayivumeli ukudibanisa ngokuthe ngqo kunye nokutya.Ukutywinwa kobushushu obuphantsi kwe-EVA kunokutywinwa kokunganyangeki kakuhle kongcoliseko.

4.Ukupakishwa kwamayeza ezinambuzane

Iimfuno zokupakisha:Kuba amayeza okubulala izitshabalalisi anetyhefu kakhulu kwaye abeka emngciphekweni ukhuseleko lomntu kunye nokusingqongileyo, ukupakishwa kufuna ukomelela okuphezulu, ukuqina okuhle, ukuxhathisa impembelelo, ukumelana nokuwa, kunye nokutywinwa okulungileyo.

Ubume boyilo:I-BOPA/VMPET/S-CPP

Isizathu soyilo: I-BOPA inokuguquguquka okulungileyo, ukuxhathisa i-puncture, amandla aphezulu kunye nokuprinta okulungileyo.I-VMPET inamandla aphezulu kunye neepropathi ezilungileyo zesithintelo, kwaye inokusebenzisa izixhobo zokwaleka ezityebileyo.I-S-CPP ibonelela ngokutywinwa kobushushu, iipropathi zomqobo kunye nokumelana nokubola, kwaye isebenzisa i-ternary copolymer PP.Okanye sebenzisa i-multi-layer co-extruded CPP equlethe i-high-barrier EVOH kunye ne-PA layers.

5. Iingxowa zokupakisha ezinzima

Iimfuno zokupakisha: Ukupakisha okunzima kusetyenziselwa ukupakisha iimveliso zezolimo ezifanairayisi, iimbotyi, iimveliso zeekhemikhali (ezifana nezichumisi), njl. Iimfuno eziphambili zinamandla amahle kunye nokuqina kunye neepropati eziyimfuneko zomqobo.

Ubume boyilo:I-PE / ilaphu leplastiki / i-PP, i-PE / iphepha / i-PE / ilaphu leplastiki / i-PE, i-PE / PE

Isizathu soyilo:I-PE ibonelela ngokutywinwa, ukuguquguquka okuhle, ukumelana nokuwa, kunye namandla aphezulu amalaphu eplastiki.
