Qhov laj thawj yog vim li cas Stretch Film yog ib qho yooj yim tawg

Cov neeg siv khoom hauv cov txheej txheem ntawm kev siv cov yeeb yaj kiab stretch, qee zaum yuav muaj kev rub tawm qhov tshwm sim, lub sijhawm no ntau tus neeg siv khoom yuav xav tias cov chaw tsim khoom hloov cov khoom siv raw hauv cov txheej txheem tsim khoom thiab ua rau muaj teeb meem zoo ntawm cov yeeb yaj kiab stretch. . Tab sis tsis yog vim li cas.

Stretch zaj duab xis no polyethylene sib tov yuav tsum tau kub ntim ntawm 100 degree, txwv tsis pub nyob rau hauv lub nro ntawm txhaws, txawm tias tsis tawg, yuav muaj ib tug loj tensile deformation.

Feem ntau, cov kua filling zaj duab xis no siv co-extruded tensile zaj duab xis nrog kub tsis kam thiab lub zog zoo, xws li nylon nplaum resin / PE. Txawm hais tias cov txheej txheej sab hauv yog PE, txheej txheej txheej yog nylon zaj duab xis, uas tuaj yeem tiv taus cua sov thiab lub zog siab, yog li lub fuse breaker tsis tuaj yeem siv los yaj thiab tawg lub hnab tshos. Kev siv PP / EVA / PE co-extrusion zaj duab xis tuaj yeem fused, tsis overheating sealing kub hauv 190-200 degree siab dua. Lub thickness yuav tsum tsim nyog nce mus rau 80-90μm kom ntseeg tau tias lub zog ntawm cov zaj duab xis sib xyaw.

Lwm qhov laj thawj vim li cas cov yeeb yaj kiab stretch yooj yim tawg yog qhov nro loj heev. Txoj kev daws teeb meem yog txo qhov nro ntawm lub tshuab ntim khoom. Qhov tseeb, tom qab sterilizing ntawm 100 degree, nws yog txias kom zoo kom txo tau qhov kub ntawm kub filling. Tsuav nws tau ua nyob rau hauv ib puag ncig ntawm chav asepsis, nws tuaj yeem txhim kho qhov teeb meem ntawm kev tawg yooj yim.
