[0002] A heat pack is a common physical therapy tool used to provide warmth to relieve pain or discomfort in certain parts of the body. Disposable heat packs use reactions between internal chemicals, such as oxidation of iron powder, to generate heat. This type of heat pack begins to heat up as soon as the package is opened and can last for several hours.

[0003] In the related art, the raw material is dropped onto the lower film, the upper film and the lower film are pressed together by a heat press, and after heat sealing, the material is moved to a cutting station to cut the hot compress bags formed on the material roll.

[0004] This production method may cause the position of the filler to deviate during the blanking process of the raw materials or the movement of the lower film (the film after receiving the material), affecting the sealing quality of the heat seal.
