A film packing device includes an axle rod and a grasp pipe. The axle rod includes at least one engaging block protruding from one side thereof. The pipe body is fitted on the axle rod. The pipe body includes a semi-circle brake block at one end thereof close to the engaging block. The brake block is coupled with a semi-circle elastic brake member. The elastic brake member has a slide block corresponding to the engaging block. When in use, the elastic brake member cooperates with the brake block to press the axle rod, such that the axle rod stops rotating. The slide block can be pushed to engage with the engaging block to stop rotation of the axle rod, so that the user can pack an article conveniently.
