纸塑袋得到了越来越广泛的应用：工业包装，食品包装，电子，航天，科技、***等各个领域都可纸塑复合袋纸塑复合袋－复合塑料编织袋是以塑料编织袋（简称布）为基材，经流延法复合后制成的（布/膜复合为二合一，布/膜/纸复合为三合一）。它们主要用于包装化肥、合成材料、、粮食、盐、矿物质等粉状或粒状的固体物料及柔性物品。关于纸塑复合袋如何分离，可使纸塑复合袋再次回收利用的方法：纯加热把纸面平放于加热板，然后通过加热板加热；当温度达到150℃～280℃之间；再加热20秒～50秒之后，这时纸塑复合材料上的塑料便会开始变形、收缩，与纸面分离。此方法可以将以前无法处理的废旧纸塑复合袋进行分离，从而使得废纸可再生使用。
Paper plastic bags have been widely used in many fields, such as industrial packaging, food packaging, electronics, aerospace, science and technology, etc. They are mainly used for packing fertilizer, synthetic material, grain, salt, mineral and other powder or granular solid materials and flexible goods. How to separate the paper plastic composite bag can make the paper plastic composite bag recycled again: put the paper surface flat on the heating plate by pure heating, and then heat it through the heating plate; when the temperature reaches 150 ℃ ~ 280 ℃; after heating for 20 ~ 50 seconds, the plastic on the paper plastic composite material will start to deform, contract and separate from the paper surface. This method can separate the waste paper plastic composite bag which can not be treated before, so that the waste paper can be reused.
