To ensure that the popcorn crispy need to pay attention to several aspects:

The quality of the fat to do popcorn should be good. Poor quality oil makes popcorn that is not crispy on its own and tends to stick to the pan.

The proportion of sugar should not be too low. Sugar is not just to increase the tandoori, but also to increase the crunchy texture.

Sealed against moisture. Popcorn is very susceptible to moisture, so you need to be careful to seal off the air in order to avoid letting the popcorn absorb moisture.
