Stretch sumla hkrung gaw packaging hpaga lam hta grai lang ai plastic sumla hkrung langai re. Shi a hkrang shapraw ai lam gaw, dai arai a bungli galaw ai lam hte quality hpe hkrak hkra machyi shangun ai. Mungkan ting na packaging ra kadawn ai lam rawt jat wa ai hte maren, stretch film a hkrang hpe chye na na matu gaw, arung arai shingjawng ai lam hpe grau kaja hkra galaw na matu ahkyak nga ai. Ndai laika hta, stretch film a madung hkrang masa ni hte arawn alai ni hpe sung sung sawk sagawn na re.
Stretch film a hkrang shapraw ai lam hta madung hku nna blow molding hte cast film ni lawm ai. Blow molding gaw ya aten hta grau nna jai lang ai ladat langai mi rai nga ai. Shi a galaw shapraw ai lam gaw, plastic raw arung arai ni hpe katsi shangun nna, hka lim kau ya ai, ring die hku nna shaw la nna, tubular film bubble langai mi hpe galaw nna, lawan ai hku katsi mat nna, katsi ai nbung ring hku nna hkrang shapraw ya ai. Blow molding ladat hte galaw shapraw ai stretch film gaw, tensile n-gun hte ngang kang ai lam grai law ai, n-gun ja ai n-gun ni hpe ra ai packaging scenario ni a matu mung htuk manu ai. Dai hta n-ga, blow molding process gaw galai shai chye ai hte, n bung ai customers ni a ra kadawn ai lam ni hpe hkap la lu na matu, ndai sumla hkrung a n-gun hte galu kaba ai lam hpe gram lajang ya lu ai.
Cast film ladat gaw kaga ahkyak ai stretch film langai mi rai nga ai. Black molding ladat hte n bung ai sha, cast film ladat gaw flat die extrusion hpaji hpe lang nna, dai hpe n-gun n rawng ai plastic hpe cooling roller ntsa de maren sha bang ya ai. Cast film ladat hte galaw shapraw ai stretch film gaw, n-gun n rawng ai hte bung ai n-gun rawng ai, dai gaw, sumla hkrung hpe asan sha chye na matu grai ra sharawng ai application ni a matu grau nna htuk manu ai. Casting ladat gaw, katsi ai lam grai law ai hte, galaw shapraw ai atsam grai law ai majaw, shi gaw, n-gun kaba ai- n-gun kaba ai hta dan dawng ai akyu ni nga ai.
Molding galaw ai lam hpe lata ai hta n-ga, stretch film hpe galaw ai hta mung raw material ratio hte stretching galaw ai zawn re ai madung link ni lawm ai. Masha law malawng lang ai raw materials ni gaw polyethylene (PE), polypropylene (PP) ni lawm ai. raw materials amyu myu hpe kayau kaya lang ai shaloi, ndai sumla hkrung a n-gun, puncture hpe ninghkap lu ai atsam hte nbung laru hpe ninghkap lu ai atsam hpe hkra machyi shangun na re. Dai n-gun jat ai lam hpe langai sha re ai stretching hte bidirectional stretching ngu nna garan nna galaw ai. Bidirectional stretching gaw ndai sumla hkrung a jak rung atsam ni hpe grai kaja hkra galaw ya lu ai majaw, packaging galaw ai aten hta grau ngang grin ai.
Htingbu htingbyen ni hpe makawp maga ra ai lam ni hpe grau kaja hkra galaw ai hte maren, jahten sharun lu ai stretch film hpe sawk sagawn ai lam hte rawt jat galu kaba wa ai lam gaw, ndai hpaga lam hta mung, n-gun ja ai shara langai mi tai wa sai. Company nkau mi gaw, plastic nhprang arai ni a majaw grup yin hpe hkra machyi ai lam hpe shayawm na matu, bio- hta lawm ai arung arai ni hpe lang hpang wa sai (sh) n kaja ai additives ni hpe bang hpang wa sai. Ndai masa gaw du na shaning loi mi laman hta stretch film hpaji masa hpe grau nna jat wa na hpe myit mada ai.
Tsun ga nga yang, n-gun jat ai sumla hkrung a molding process gaw shi a bungli galaw ai lam hte gat lawk shingjawng ai lam hpe hkrak hkra machyi shangun ai. Blow molding rai tim, casting galaw ai rai tim, raw material lata ai lam hte process optimization hpe kayau kaya galaw nna, market ra kadawn ai lam hpe hkan sa ai tsaw ai{1}} manu dan ai arung arai ni hpe galaw shapraw ra ai. Ndai lam ni hpe chye na ai gaw, company ni hpe n-gun ja ai gat lawk shingjawng ai lam hta akyu lu la na matu karum ya na re.
