Zihlolwa njani iingxowa zeplastiki? Yintoni naimigangatho yokuhlolakwiingxowa zeplastiki ezisetyenziselwa ukupakisha ukutya?
Ukwamkela imigangatho kunye nokuhlelwa
1. Umgangatho wasekhaya wokuhlolwa kwengxowa yeplastiki: I-GB/T 41168-2021 Ifilimu yeplastiki kunye nefoyile yealuminium ehlanganisiweyo kunye nebhegi yokupakisha ukutya
2. Ukuhlelwa
-Ngokwesakhiwo: Iingxowa zeplastiki zokutya zohlulwe zibe yiKlasi A kunye neKlasi B ngokwesakhiwo
-Ihlelwa ngokweqondo lobushushu bokusetyenziswa: Iingxowa zeplastiki zokutya zihlelwa ngokwebakala lokubilisa, ibakala elisezantsi lobushushu obuphezulu, kunye nenqanaba lobushushu obuphezulu ngokweqondo lobushushu bokusetyenziswa.
Imbonakalo kunye nobugcisa
-Jonga ngokubonakalayo phantsi kokukhanya kwendalo kunye nomlinganiselo ngesixhobo sokulinganisa ngokuchaneka okungekho ngaphantsi kwe-0.5mm:
-Imibimbi: Imibimbi emincinci encinci ivumelekile, kodwa ingadluli kwi-5% yendawo yemveliso;
-Imikrwelo, ukutsha, ukubhoboza, ukuncamathela, izinto zasemzini, ukubola, nobumdaka akuvumelekanga;
-I-Elasticity ye-film roll: akukho sliding phakathi kweefilimu ezijikelezayo xa uhamba;
-I-Film roll eveziweyo yokuqinisa: Ukuqiniswa okubonakalayo okuncinci okungachaphazeli ukusetyenziswa kuvunyelwe;
-Ukungalingani kobuso bokuphela kwefilimu: akukho mkhulu kune-2mm;
-Inxalenye yokutywinwa kobushushu yesikhwama isicaba, ngaphandle kokutywinwa okuxekethileyo, kwaye ivumela iibhubhu ezingachaphazeli ukusetyenziswa kwayo.
Ukupakishwa/ukuchongwa/ukuleyibheli
Iphakheji nganye yemveliso kufuneka ihambe kunye nesatifikethi sokuhambelana kwaye ibonise igama lemveliso, udidi, iinkcukacha, iimeko zokusetyenziswa (ubushushu, ixesha), ubuninzi, umgangatho, inombolo yebhetshi, umhla wokuvelisa, ikhowudi yomhloli, iyunithi yokuvelisa, idilesi yeyunithi yokuvelisa. , inombolo yokwenziwa komgangatho, njl.
Iimfuno zokusebenza komzimba kunye noomatshini
1. Ivumba elingaqhelekanga
Ukuba umgama osuka kwisampulu yovavanyo ungaphantsi kwe-100mm, yenza uvavanyo lwevumba kwaye akukho vumba elingaqhelekanga.
2.Ukudibanisa
3. Ukuhlolwa kwengxowa yeplastiki - ukutenxa kobungakanani:
3.1 Ukutenxa kubungakanani befilimu
3.2 Ukutenxa kubungakanani beengxowa
Ukuphambuka kobungakanani besikhwama kufuneka kuhambelane nemimiselo kwitheyibhile engezantsi. Ububanzi bokutywinwa kobushushu besikhwama buya kulinganiswa ngesixhobo sokulinganisa ngokuchaneka okungekho ngaphantsi kwe-0.5mm.
Ukuhlolwa kwengxowa yePlastiki yesi-4-iiPropati zoMzimba kunye nezoomatshini
4.1 Amandla e-Peel of bag
4.2 Amandla okuvala ubushushu bengxowa
4.3 Amandla okuqina, uxinzelelo lwegama ngexesha lokuphumla, i-angle yasekunene yokukrazula amandla, kunye nokumelana namandla empembelelo ye-pendulum
Isimbo sithatha imilo emide yomgca, ubude be-150mm kunye nobubanzi be-15mm ± 0.3mm. Isithuba phakathi kwezixhobo zesitayile yi-100mm ± 1mm, kwaye isantya esisolula sesimbo yi-200mm/min ± 20mm/min.
4.4 Ingxowa yePlastiki yokungena kwamanzi umphunga kunye ne-oxygen permeability
Ngexesha lovavanyo, umphezulu woqhagamshelwano womxholo kufuneka ujongane necala loxinzelelo oluphantsi okanye icala elisezantsi loxinzelelo lomphunga wamanzi, kunye nobushushu bovavanyo obuyi-38 ° ± 0.6 ° kunye nokufuma okunxulumene ne-90% ± 2%.
4.5 Ukumelana noxinzelelo lweengxowa zeplastiki
4.6 Ukwehla kokusebenza kweengxowa zeplastiki
4.7 Ukuxhathisa ubushushu kwiingxowa zeplastiki
Emva kovavanyo lokumelana nobushushu, akufuneki kubekho ukuguquguquka okucacileyo, ukuguqulwa, ukuxobulwa kwe-interlayer, okanye ukutywinwa kokutywinwa kobushushu kunye nezinye izinto ezingaqhelekanga. Xa isampuli yetywina iphukile, kuyimfuneko ukuthatha isampuli kwaye uphinde uyenze.
Ukususela ekutyeni okutsha ukuya kulungele ukutya, ukusuka kwiinkozo ukuya enyameni, ukusuka kwipakethe nganye ukuya kwipakethe yokuthutha, ukusuka kukutya okuqinileyo ukuya kukutya okumanzi, iingxowa zeplastiki ziye zaba yinxalenye yoshishino lokutya. Le ingentla yimigangatho kunye neendlela zokuhlola iingxowa zeplastiki ezisetyenziswa ekupakishweni kokutya ukuqinisekisa ukhuseleko lokutya.
