Izimpawu nokuhlukaniswa kwezikhwama ze-EVA namabhokisi e-EVA

I-EVA iyimpahla yepulasitiki eyenziwe nge-ethylene (E) ne-vinyl acetate (VA). Isilinganiso salawa makhemikhali amabili singalungiswa ukuze sihlangabezane nezidingo ezahlukene zohlelo. Ukuphakama kokuqukethwe kwe-vinyl acetate (okuqukethwe kwe-VA), kuyanda ukukhanya kwayo, ukuthambile nokuqina kwayo.

Izici ze-EVA ne-PEVA yilezi:

1. I-biodegradable: Ngeke ilimaze imvelo lapho ilahlwa noma ishiswa.

2. Ngokufanayo nentengo ye-PVC: I-EVA ibiza kakhulu kune-PVC enobuthi, kodwa ishibhile kune-PVC ngaphandle kwama-phthalates.

3. I-Lightweight: Ukuminyana kwe-EVA kusuka ku-0.91 kuya ku-0.93, kuyilapho eye-PVC ingu-1.32.

4. Ayinaphunga: I-EVA ayinayo i-ammonia noma amanye amaphunga aphilayo.

5. Ayinansimbi enamandla: Ihambisana nemithetho yamathoyizi yamazwe ngamazwe efanele (EN-71 Ingxenye 3 kanye ne-ASTM-F963).

6. I-Phthalates-free: Ilungele amathoyizi ezingane futhi ngeke ibangele ubungozi bokukhishwa kwe-plasticizer.

7. Ukucaca okuphezulu, ukuthambile kanye nokuqina: ububanzi besicelo bubanzi kakhulu.

8. Ukumelana nokushisa okuphansi kakhulu (-70C): kulungele imvelo ye-icing.

9. Ukumelana namanzi, usawoti kanye nezinye izinto: zingahlala zizinzile ngenani elikhulu lezicelo.

10. Ukushisa okuphezulu okunamathelayo: kungaxhunyaniswa ngokuqinile neyiloni, i-polyester, i-canvas nezinye izindwangu.

11. Ukushisa okuphansi kwe-lamination: kungasheshisa ukukhiqizwa.

12. Ingaphrintwa isikrini futhi iphrinte i-offset: ingasetshenziselwa imikhiqizo esezingeni eliphezulu (kodwa kufanele isebenzise uyinki we-EVA).

I-EVA lining, njengoba igama libonisa, umkhiqizo othile obekwe kuleli bhokisi le-EVA, bese kudingeka iphakheji ngaphandle, futhi ulayini lwe-EVA lubekwe kule phakheji. Leli phakethe lingaba ibhokisi lensimbi lensimbi, noma ibhokisi lekhadibhodi elimhlophe noma ibhokisi.

Ukuhlukaniswa okubalulekile komugqa wokupakisha we-EVA

I-EVA Packaging Linening ihlukaniswe ikakhulukazi ngamaphoyinti alandelayo:

1. Ukuminyana okuphansi, ukuminyana okuphansi kwe-EVA enobungani bemvelo, emnyama, emhlophe nombala.

2. High-density, high-density high-friendly imvelo EVA, emnyama, emhlophe kanye nombala.

3. I-EVA ivaliwe iseli 28 degrees, 33 degrees, 38 degrees, 42 degrees.

4. I-EVA ivula iseli 25 degrees, 38 degrees
