EVA Side Gusset Matumba
Matumba amtundu wa EVA am'mbali amakhala oblong, ndipo nthawi zambiri amagwiritsidwa ntchito ngati matumba a liner a matumba oluka okhala ndi ntchito yodzipatula, kusindikiza komanso kutsimikizira chinyezi. Chifukwa cha kapangidwe ka gusset kumbali, ikayikidwa mu thumba lakunja, imatha kukwanira bwino ndi thumba lakunja. Kuphatikiza apo, imatha kuyikidwa mu chosakaniza kapena mphero panthawi yosakaniza.
Tikhoza kupanga matumba ndi mfundo yomaliza kusungunuka ndi pamwamba 65 digiri Celsius, kutsegula pakamwa kukula 40-80cm, mbali gusset m'lifupi 10-30cm, kutalika 30-120cm, makulidwe 0.03-0.07mm.
