Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1, a degradable waterproof aluminum-foil paper shown in the figure comprises an aluminum-foil paper layer 1, a water absorbing member 2 disposed on one side of the aluminum-foil paper layer 1, and a waterproof member 3 disposed on the other side of the aluminum-foil paper layer 1.

Referring to fig. 1-2, the water absorbing member 2 includes a storage bag layer 4, a drying agent 5 is disposed inside the storage bag layer 4, and the storage bag layer 4 is made of dupont paper.

In this embodiment, one side through being close to the cigarette at aluminium foil paper layer 1 sets up water absorption piece 2, come to carry out drying effect to the cigarette, prevent that the cigarette from making damp and deteriorating, influence the taste, simultaneously through setting up waterproof piece 3 in aluminium foil paper layer 1's the outside, isolated external moisture, thereby can carry out comparatively intact saving to the cigarette, dupont paper material has good leakproofness water permeability, can be used for packing drier 5, dupont paper can be by biodegradable simultaneously, is the material of comparatively environmental protection.
