冰袋，广泛用于水果、蔬菜、疫苗等物品的保鲜快递运输和医用冷敷。目前市场普遍使用的是自吸式冰袋，这种冰袋的特点就是使用起来较为方便，可以有效改善传统冰袋低效率注水的情况。
自吸式冰袋无毒、无味、无腐蚀，可重复使用，其有冷到时长是冰的3～4倍，可代替冰作为热交换载体传递热量的冷冻介质。那么，在使用自吸式冰袋有哪些需要注意的呢？
首先，自吸式冰袋内含有高分子蓄冷吸水材料，吸水性能强大，能自动吸收自身重量的几十到几百倍的水。
其次，冰袋内材料吸水后成凝胶状，请勿用力挤压或与锐利物品接触，避免过大的压力导致冰袋破裂，从而影响其使用性能。
自吸式冰袋的正确使用方法：
1、只需将它放入水中浸泡 3～5分钟，就能使其充分膨胀，免去人工注水的烦琐操作。
2、待冰袋充分膨胀取出后擦拭冰袋表面多余的水分静止5分钟左右，再将冰袋放入冰箱冷冻6小时以上
温馨提醒：泡沫箱+保温袋+冰袋搭配使用的话保冷效果更好。
Self-priming ice pack non-toxic, tasteless, non-corrosion, reusable, its cold to 3 ~ 4 times the length of ice, can replace ice as a heat exchange carrier transfer heat freezing medium. So, in the use of self-priming ice pack what need to pay attention to?
First of all, the self-imbibition ice pack contains polymer cold storage water absorption materials, water absorption performance is strong, can automatically absorb their own weight of tens to hundreds of times the water.
Secondly, the material in the ice pack after absorbing water into a gel, do not squeeze hard or contact with sharp objects, to avoid too much pressure to lead to the rupture of the ice pack, thus affecting its performance.
The correct use of self-priming ice pack:
1, just put it into the water soaking 3 ~ 5 minutes, can make it fully expanded, without the tedious operation of artificial water injection.
2. After the ice pack is fully expanded and removed, wipe the excess water on the surface of the ice pack and rest for about 5 minutes, and then put the ice pack in the refrigerator for more than 6 hours
Warm reminder: The combination of foam box + insulation bag + ice bag can keep the cold better.
