Stretch Film hi plastic film a ni a, logistics packaging, industrial production leh consumer product humhalhna lama hman lar tak a ni. Material selection hian direct takin product a performance, cost leh environment friendliness a nghawng a ni. Stretch Film-a thil pawimawh ber leh a nihna hriatthiamna chuan a lei leh end user-te chu mamawh tak tak atanga duhthlanna dik zawk siam turin a pui ang.
Polyethylene (PE) - Stretch film-a thil pawimawh ber berte chu a ni.
Polyethylene (PE for short) hi stretch film material zingah chuan a tam ber a, a lar ber pawl a ni. Low-density polyethylene (LDPE), linear low-density polyethylene (LDDPE) leh high-density polyethylene (HDPE) te chu density hrang hrang angin a then theih a ni. Chumi zingah chuan LLDPE chu stretch film thlan ber a ni ta a, a chhan chu a tensile strength tha tak, puncture resistance leh flexibility a neih vang a ni.
LDPE stretch film hian transparency tha tak a nei a, mahse tensile property a chak lo hle a, a tam zawk chu thil rit lo tak tak packaging atan hman a ni. LLDPE stretch film hi thil rit tak tak, pallet packaging leh field dang dangah te hman a ni nasa hle a, a chhan chu a tensile strength sang zawk leh a resilience vang a ni. HDPE stretch film hian chakna sang zawk nei mahse, flexibility tha lo tak a nei a, mamawh bik nei packaging scenario-ah pawh hman a ni tlangpui.
Polypropylene (PP) - chakna sang tak leh heat resistance thlan theihna
Polypropylene (PP) Stretch Film hian hmun bik thenkhatah chuan tensile strength sang tak leh heat resistance a neih avangin a thatna a nei a ni. PP stretch film hi PE stretch film aiin a khauh zawk a, packaging environment-a temperature sang tak emaw, mechanical stress emaw tuar ngai, chemical products, building materials, etc. Mahse, PP stretch film hian transparency a nei tlem a, PE angin a flexible lo a, chuvangin general packaging market-ah chuan hman a tlem hle.
Degradable Materials - Environment humhalhna kalphung hnuaia duhthlanna thar
Environment awareness a pun zel avangin degradable stretch film chu zawi zawiin industry-ah thupui lar tak a ni chho ta a ni. Hetiang chi thil hi bio-based plastic (PLA, PHA ang chi) emaw PE/PP material hmanga siam a ni tlangpui a, added degradation agents a awm a, chu chuan natural environment-ah a ti chhe rang thei a, plastic pollution a ti tlem thei bawk. Tunah hian degradable stretch film man hi a sang hle a, technological lama hmasawnna leh policy tihhmasawn a nih avangin a market share pawh a zau chho zel dawn niin a lang.
Khaihtawi
Stretch film-a material thlan dan hian packaging mamawh, cost leh environmental factors te chu a huam zau zawnga ngaihtuah a ngai a ni. PE material hi a performance kimchang tak avang hian market-a mainstream a la ni reng a, PP leh degradable materials te hian scenario bik atan thil awm thei tam zawk a pe thung. Nakin lawkah chuan Materials Science hmasawnna nen chuan Stretch Film-a materials te chu industry hrang hrangte packaging mamawh phuhruk nan a inthlak danglam nasa zawk dawn a ni.
