In order to achieve the above purpose, the utility model adopts the following technical scheme:

a moisture-absorbing and moisture-proof plastic film for packaging comprises a substrate layer, an outer plastic layer and an inner plastic layer, wherein the substrate layer is positioned between the outer plastic layer and the inner plastic layer, a first moisture-proof layer is arranged between the substrate layer and the outer plastic layer, and a second moisture-proof layer is arranged between the substrate layer and the inner plastic layer;

a reinforcing layer is embedded in the base material layer;

first dampproof course and second dampproof course all include upper strata and lower floor and constitute, a plurality of evenly distributed's standing groove is all seted up to upper strata and the relative one side of lower floor, and is a plurality of the inside of standing groove all is filled there is silicon dioxide.

Preferably, the reinforcing layer is arranged in a wave-shaped distribution.

Preferably, the upper layer and the lower layer are bonded and fixed by glue.

Preferably, the placing grooves which are arranged side by side are arranged in an alternating and staggered manner.

Preferably, the outer plastic layer and the inner plastic layer are both polyethylene films.

Preferably, the reinforcing layer is made of a high density polyethylene material.

Compared with the prior art, the utility model provides a moisture absorption dampproofing plastic film for packing possesses following beneficial effect:

1. this moisture absorption damp proof plastic film for packing through the first dampproof course, the second dampproof course, upper strata, lower floor, standing groove and the silica that is equipped with, can guarantee to possess higher waterproof performance between outer plastic layer and substrate layer and interior plastic layer and the substrate layer.

2. This a moisture absorption dampproofing plastic film for packing through the enhancement layer that is equipped with, can guarantee the resistant performance of pulling of substrate layer to the whole resistance of having guaranteed the plastic film is pulled the performance.

The part that does not relate to in the device all is the same with prior art or can adopt prior art to realize, the utility model discloses not only moisture absorption humidity resistance is high, and the whole of plastic film is resisted to pull the performance strong.
