However, not all flexible packaging can be heated in a microwave oven. The pouch needs to fit the following requirements.

     1.Heat-resisting. As we all know, most of the flexible packaging is made from plastic. Usually, the plastic cannot stand against high temperature. They might deform, become thinner or separate out some kind of poison after heating. In this case, pouch bag manufacturers use some special material that retorts pouches also using to produce microwaveable pouch --- RCPP. Because of the characteristic of RCPP, The pouch with such material can stand against high temperature up to 121℃ for 30 minutes. Except for plastic material, choice of ink/glue is very important, too. In fact, some ink/glue will separate out some kind of poison after being heated. Therefore it is necessary to find some ink/glue that can bear high-temperature heating.

       2. Metal-free & high barrier. As we all know, it is dangerous to put metal into a microwave oven. However, flexible packaging usually uses aluminum foil or some other metalized material to acquire high-barrier.Such materials contain a different kind of metal. So it is not available to put pouches with this material into a microwave oven. So, how can we make microwaveable & high-barrier coexist? The solution gave by pouch bag manufacturers is ALOXPET/SIOXPET, which means Aluminum oxide PET/ Silicon oxide PET.
