Embodiment Construction
[0053] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0054] like figure 1 , image 3 , Figure 4 and Figure 5 Shown, the first to the fourth content of the present invention, this product is pre-designed as reusable, light-proof, waterproof type multifunctional cushioning packaging material bag 6 according to the size requirement of the packaged object, and the air is provided by the distribution supply main pipe during use The opening 3 of 4 enters, passes through the channel opening of the false heat seal 5 through the gap between 2a and 2b, and passes through 8 to make the air circulate according to the designed circuit, and enters each space 7 smoothly from the air channel between 2a and 2b. As the air flow increases, the space 7 begins to expand gradually. When the inflation is stopped, the gap between 2a and 2b will automatically stick together due to the special properties of the inner...
