Marka la barbar dhigo filimka EVOH-ka-baxa, EHA waxay ku gaari kartaa saameyn isku mid ah EVOH laakiin walxo ka yar sababtoo ah habka casriga ah ee LISIM habka fidinta ee isku mar ah, iyo dhumucda EHA waa 15μm oo kaliya taas oo ah kharash badan oo waxtar leh .
Intaa waxaa dheer, daabacaadda aadka u wanaagsan ee EHA waxay khusayn kartaa diiwaangelin sax ah oo kala duwan.Marka la barbar dhigo PVDC ama qalabka kale ee dahaarka sare leh, EHA waxay gaari kartaa daabacaadda dhibco yaryar oo aad u wanaagsan.
Astaamaha | Faa'iidooyinka |
✦ Gaaska/carafka sare ee udgoonka | ✦ Kordhi cimriga shelf, cusbayn wanaagsan |
✦Awood farsamo sare leh iyo iska caabin daloolin/saameyn | ✦Awood u leh in lagu xidho badeecooyin ka culus/weyn, qallafsan ama lafo fiiqan |
✦ Degnaansho cabbir wanaagsan ✦ Ma jiro wax lumin ah oo luminaya marka filimku xumaado ✦Qafiif ah laakiin hawlo badan leh | ✦Daabcado sax ah ✦ caqabad xasiloon ✦Qiimaha waxtarka leh |

EHAp waa filim hufan, xannibaad sare leh.Waxay u adkaysataa 85 ℃ karkarinta ama 105 ℃ buuxinta kulul, OTR ka hooseeya 2 CC/m2.d.atm.Marka la barbardhigo filimada caadiga ah ee BOPA, waxqabadka iska caabbinta oksijiinta ee EHAp waa toban jeer ka sii fiican, taas oo ka dhigaysa mid aad ugu habboon baakadaha kaas oo leh shuruudo adag oo ku saabsan xannibaadda gaaska, sida cuntada xayawaanka ah, xawaashka isku dhafan, macmacaan leh nolol shelf gaaban, jiis, kernels, cabitaanada caanaha halsano iyo buufinaha sare.
Boorsada ama karkarinta ka dib
✔ Heerkulka daboolida kulaylka xad dhaafka ah ama waqti dheer
✔ Qaab-dhismeedka lakabyada gudaha iyo dibaddaba si aan habboonayn
✔ Xiisad aan joogto ahayn oo u dhaxaysa xagga hore iyo dambe ee bacaha
