Gupfa-Gukata Inzira yo Kurinda Ibirahure

Muburyo bwo gupfa,firime yo kurinda ibirahure bigomba gukatirwa icyarimwe nibikoresho byo mumaso hamwe nibifatika, ariko mubyukuri, gukata impapuro zimeze nkibikoresho byahujwe nigisubizo cyo gukata ibikoresho no kuvunika impapuro, ni ukuvuga gukata icyuma kumanura hasi nabyo bizanyunyuza impapuro , kubwibyo, ugereranije, gupfa-gukata neza nkibikoresho byimpapuro ntabwo biri hejuru. Isesengura ry'icyitegererezo rikunze kuboneka kuri labels zimwe na zimwe zifite burrs, ibyo bikaba biterwa na fibre fibre mbisi iba ari mike, hamwe nibigize ibintu biterwa no kuvunika bisanzwe.

Filime ikingira ibirahure ishingiye ku guca ibintu bipfa kuranga impapuro zishingiye ku mpapuro, no kuzirikana kwambara no kurira by'icyuma, abakora firime zo gukingira PE birinda icyuma gipima icyuma cya 52 °, ukeka ko inguni ari nini, gusohora Guhindura ibikoresho birahambaye cyane, ni ukuvuga, icyerekezo gitambitse cyingufu zakarere zigize ibintu bizatuma ibintu bitandukanya ibice bivunika. Nkuko ibyinshi mubikoresho byubwoko bwa firime bifite ubukana kandi ntibishobora kuvunika bisanzwe, guca muri bibiri bya gatatu ntibikwiye guca burundu cyangwa guca umubyimba wa bine bya gatanu kugirango ugabanye; bitabaye ibyo, umurongo wimyanda uzahanagurwa hamwe na label.

Ikirahure kirinda ibintu hejuru yububiko nimbaraga zububiko, fibre (macromolecule), nubushuhe. Muburyo bwo gupfa ibintu bya PET birinda ibikoresho bya firime, ikintu nyamukuru kijyanye nibikoresho byo hejuru ni umuvuduko wo gutemba. Nubushuhe bwinshi bwibihe, abakora firime ya PE ikingira nyuma yubushuhe, imbaraga nke, imbaraga zidahita zikuramo, ndetse ntizishobora gusohoka.

Filime ikingira ibirahuri ikoresha ubunini bwibintu byo mumaso. Umubyimba wibintu uzagira ingaruka kuburyo butaziguye bwo gupfa; umubyimba wibikoresho byayo, niko gupfa-bizagenda. Kuberako ibintu byuzuye, niko bisobanutse neza byo gupfa, bityo amahirwe make yo guca mumpapuro fatizo. Ibikoresho byoroheje, niko bisanzwe guca intege inenge. Tandukanya ibikoresho byo mumaso nimpapuro zifatizo; kurugero, irashobora kuba 80g / m2 na 60g / m2, ijyanye nimbonerahamwe iringaniza ikirango imashini ipfa. Ubushakashatsi bwerekanye ko 80g / m2 ibikoresho bipfa gupfa ari ibisanzwe; guhinduranya ibintu 60g / m2, gupfa-gupfa akenshi bitera kumenagura imyanda, impapuro zifatizo ziracibwa, gutakaza ibimenyetso, nibindi bintu, bisaba guhagarara kenshi hamwe na plaque.
