According to the vacuumizing-free vacuum compression bag and the multilayer compound equipment thereof provided by the scheme of the invention, a vacuum compression bag 6 is placed with an article to be stored through the sealing edge 62 and the end of the bone-sticking zipper 63, after the bone-sticking zipper 63 is stuck, the bag body of the vacuum compression bag 6 is pressed, the gas in the bag body is exhausted through the one-way exhaust device I65 and the one-way exhaust device II 66 at the top end of the bag body, and the ambient air can not enter the vacuum compression bag 6 any more, so that the article in the compression bag can be conveniently stored, and the occupied space for storing the article is reduced.

The invention relates to a multi-layer compounding device of an air-pumping-free vacuum compression bag, which compounds base materials with different characteristics and functions through a specific compounding key technology, thereby realizing the functionalization and high performance of a composite packaging material, utilizes the composite packaging material to make a bag, thereby realizing the industrialization of the air-pumping-free vacuum compression bag, ensures the use strength of the composite film after the compounding is finished through pressing and tension adjustment, and carries out nail line treatment on the composite film through a binding device, thereby strengthening the firmness of the composite film and ensuring the storage safety of articles, and after the composite film is coiled, corresponding patterns are printed after quality inspection is qualified, and then the composite film can be cut into the production process of the vacuum compression bag 6.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
