Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-3, a dampproofing composite packaging material, include the inlayer of laminating in proper order from inside to outside, intermediate level and skin, the skin is waterproof layer 1, the inlayer is polyethylene layer 2, the intermediate level is supporting layer 3, supporting layer 3's surface evenly distributed has through-hole 4, the inner wall of through-hole 4 has adsorbed layer 5 and dry layer 6 by laminating in proper order from outside to inside, through setting up waterproof layer 1, adsorbed layer 5 and dry layer 6, the one deck waterproof layer is handled water, with thorough cleaing away of moisture, avoid moisture to get into the inside condition that causes the object of being packaged to wet by the object of being packaged.

Still the laminating has aluminium foil layer 7 between intermediate level and the inlayer, and the aluminium foil has stronger vapor transmission rate separation nature and oxygen transmission rate separation nature for the aqueous vapor can stop inside the through-hole, can prevent that steam from getting into the inlayer, makes that adsorbed layer 5 and 6 better of dry layer handle moisture.

The adsorption layer 5 is an activated carbon adsorption layer, a polyacrylamide adsorption layer or a zeolite molecular sieve adsorption layer, and water drops and water vapor are adsorbed to prevent water from flowing into an inner layer.
