飯盒保溫袋可以(yi)曬太陽(yang)，保溫袋定做(zuo)，但是不宜長期暴(bao)曬。太陽(yang)光(guang)中含有紫外線(xian)及熱能會(hui)影響到(dao)塑料(liao)的(de)材質變脆和(he)老化，而(er)且(qie)高(gao)溫環(huan)境下細菌也會(hui)被(bei)殺滅。所以(yi)將飯菜裝在(zai)帶(dai)有密(mi)封性的(de)袋子中（好是用帶(dai)有的(de)金屬材料(liao)的(de)夾層），然后放(fang)到(dao)強烈的(de)陽(yang)光(guang)下曝哂(shen)約1-2小時后即可其中的(de)大量病菌、或等有害物質。”

鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)是一(yi)種(zhong)常見的(de)(de)(de)(de)(de)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)材(cai)料，但它也存在(zai)(zai)一(yi)些缺點(dian)。首先(xian)，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)在(zai)(zai)使(shi)用(yong)(yong)過(guo)程中(zhong)容(rong)易(yi)破(po)損(sun)。由于鋁(lv)(lv)(lv)(lv)箔(bo)(bo)的(de)(de)(de)(de)(de)柔軟性(xing)(xing)(xing)較(jiao)(jiao)差(cha)，容(rong)易(yi)被尖(jian)銳(rui)物(wu)體(ti)劃破(po)或撕裂(lie)，從而(er)降低保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)效(xiao)果(guo)。此外(wai)，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)的(de)(de)(de)(de)(de)密封(feng)性(xing)(xing)(xing)也不夠理(li)想，容(rong)易(yi)導致(zhi)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)內(nei)部(bu)的(de)(de)(de)(de)(de)熱(re)量逃逸或外(wai)部(bu)的(de)(de)(de)(de)(de)空(kong)氣進入，進而(er)影響(xiang)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)效(xiao)果(guo)。其次，奶茶保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)的(de)(de)(de)(de)(de)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)性(xing)(xing)(xing)能(neng)(neng)相對較(jiao)(jiao)差(cha)。雖然鋁(lv)(lv)(lv)(lv)箔(bo)(bo)具有良好的(de)(de)(de)(de)(de)隔熱(re)性(xing)(xing)(xing)能(neng)(neng)，但單純的(de)(de)(de)(de)(de)鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)往(wang)往(wang)無法滿足較(jiao)(jiao)高的(de)(de)(de)(de)(de)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)要求。特別是在(zai)(zai)溫(wen)(wen)(wen)(wen)(wen)度條件下(xia)，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)的(de)(de)(de)(de)(de)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)效(xiao)果(guo)可(ke)能(neng)(neng)會(hui)大打折扣，無法起到很好的(de)(de)(de)(de)(de)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)效(xiao)果(guo)。此外(wai)，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)的(de)(de)(de)(de)(de)材(cai)料成本較(jiao)(jiao)高。相比其他保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)材(cai)料，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)的(de)(de)(de)(de)(de)價格較(jiao)(jiao)高，保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)廠家，這導致(zhi)鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)的(de)(de)(de)(de)(de)價格也相對較(jiao)(jiao)高，增加了用(yong)(yong)戶的(de)(de)(de)(de)(de)經濟負擔。，阜陽保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)，鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)的(de)(de)(de)(de)(de)可(ke)持續性(xing)(xing)(xing)較(jiao)(jiao)差(cha)。鋁(lv)(lv)(lv)(lv)箔(bo)(bo)是一(yi)種(zhong)不可(ke)降解(jie)的(de)(de)(de)(de)(de)材(cai)料，難以進行回收(shou)和再利(li)用(yong)(yong)。大量的(de)(de)(de)(de)(de)鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)使(shi)用(yong)(yong)后往(wang)往(wang)被丟棄(qi)，對環境造成了一(yi)定的(de)(de)(de)(de)(de)影響(xiang)。綜上所(suo)述，雖然鋁(lv)(lv)(lv)(lv)箔(bo)(bo)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)袋(dai)在(zai)(zai)一(yi)定程度上能(neng)(neng)夠提供(gong)保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)效(xiao)果(guo)，但其存在(zai)(zai)易(yi)破(po)損(sun)、保(bao)(bao)(bao)(bao)(bao)(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)性(xing)(xing)(xing)能(neng)(neng)不足、材(cai)料成本高以及可(ke)持續性(xing)(xing)(xing)差(cha)等缺點(dian)，需(xu)要在(zai)(zai)使(shi)用(yong)(yong)時進行合理(li)的(de)(de)(de)(de)(de)選擇和應用(yong)(yong)。
