環保(bao)熱收(shou)縮膜的優良性能有(you)哪些

1. 物性，POF薄而韌，厚度(du)均(jun)勻，防潮性佳，質地柔軟，抗拉(la)強(qiang)度(du)高，耐撕裂強(qiang)度(du)大，收縮率(lv)可調(diao)，pof筒膜(mo)桶膜(mo)定制，因LLDPE存在，耐揉(rou)搓性更好(hao)。

2. 耐寒(han)，等物性(xing)POF耐寒(han)性(xing)好，不(bu)(bu)(bu)硬不(bu)(bu)(bu)脆，不(bu)(bu)(bu)易，可用(yong)于冷凍食(shi)品(pin)包(bao)裝。收縮包(bao)裝后，-50℃--95℃被包(bao)裝物長期存放，穩(wen)定不(bu)(bu)(bu)變(bian)。有靜電(dian)和防霧處理(li)，不(bu)(bu)(bu)易沾染灰塵，可保持產品(pin)清潔亮麗。

3. 加工(gong)性(xing)能(neng)，POF加工(gong)過程不產生(sheng)水分也不會粘著于(yu)(yu)封棒上，保養及作業容易，高韌性(xing)、平滑性(xing)及抗揉搓性(xing)使其適用(yong)于(yu)(yu)高速生(sheng)產線自動包(bao)裝。

4. 安quan性(xing)，POF收縮包裝后(hou)，封口處(chu)四角柔(rou)軟，不會割傷人手(shou)，也(ye)耐揉搓。

5. 環保衛生，POF***性，加工時不產生有毒氣味，符合FDA和USDA標準。
