Description

Recyclable and waterproof bag

The present invention relates to a packaging bag, and more particularly to a recyclable and waterproof bag.

A packaging bag comprising a bag body having a bag mouth and a bag bottom, the bag body comprising a woven fabric layer woven from a plastic material, and a side layer attached to the inner side of the woven fabric layer And the coating layer of plastic material.

However, since the bag body of the bag has only a double-layer structure, the airtight effect is relatively poor, so if a better water and gas barrier effect is desired, it is usually nested in the bag. Bagging. In use, the article is placed in the inner bag, and then the package is sealed, and the inner bag is used to increase the barrier effect of water and gas. However, the above-mentioned method requires manual insertion into the inner bag and the bag body, which is cumbersome and inconvenient in operation, so there is still room for improvement.

Therefore, the object of the present invention is to provide a recyclable and waterproof gas-packing bag which has a good moisture barrier effect and is convenient to use.

Therefore, the bag of the recyclable and waterproof gas comprises a bag body surrounding an axis and defining an accommodating space, an opening formed at a top end of the bag body and communicating to the accommodating space, and a a bottom end of the bag body and a closed bag bottom, the bag body comprises a base layer made of polypropylene material, a film layer attached to the outer side surface of the base layer layer and made of polypropylene material, and a layer attached thereto A woven fabric layer made of polypropylene and woven on the outer side of the coating.

The utility model has the advantages that the base layer is disposed on the innermost layer of the bag body to increase the waterproof gas of the bag body, and the method of inserting an inner bag is described in the prior art. This new type is more convenient to use.

The other features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the present invention. FIG. 1 is a perspective view of a preferred embodiment of the present invention. Figure 2 is a cross-sectional view of the preferred embodiment.

Referring to FIG. 1 and FIG. 2, a preferred embodiment of the recyclable and waterproof gas-packing bag 10 includes a bag body 2 surrounding an axis L and defining an accommodating space 3, and a bag body formed on the bag body. 2 an opening 4 connected to the accommodating space 3 at the top end, a bag bottom 5 formed at the bottom end of the bag body 2 and closed, and a cover provided on the bottom 5 of the bag and being polypropylene (Polypropylene, PP) ) Material sealing strip 6.

The bag body 2 comprises a base layer 21 made of polypropylene material. The coating layer 22 is made of a polypropylene material and is attached to the outer surface of the base layer 21, and a woven fabric layer 23 which is attached to the outer surface of the coating layer 22 and woven with a polypropylene material.

Wherein, the function of the base layer 21 is mainly equivalent to the previous The inner bag described in the art is mainly used for blocking moisture. The function of the laminating layer 22 is mainly to enable the base layer 21 and the woven fabric layer 23 to be bonded together. The substrate layer 21, the coating layer 22, and the manufacturing method of the woven fabric layer 23 are respectively known to those skilled in the art, and thus are not described in detail herein. The base layer 21 of the bag bottom 5 corresponding to each other is bonded by hot melt bonding, and then folded and folded in a folded shape to cover the sealing strip 6, so that the bottom of the bag can be effectively lifted. The structural strength of 5, as well as the effect of waterproof gas. On the other hand, since the base layer 21, the coating layer 22, and the woven fabric layer 23 are each a single material of polypropylene, it is convenient and simple to recycle, so the environmental protection is more beneficial. Big.

In summary, the novel recyclable and waterproof gas bag 10 has the following advantages and effects:

1. The base layer 21 is disposed on the innermost layer of the bag body 2 to increase the waterproofing effect of the bag body 2, and the method of inserting an inner bag is described in the prior art. The new type is more convenient to use.

2. The base layer 21 of the bag bottom 5 corresponding to each other is bonded together by hot melt bonding, and then folded in half to form a folded shape. The sealing strip 6 is coated, so that the structural strength of the bottom 5 and the effect of the waterproof gas can be effectively enhanced.

3. The base layer 21, the coating layer 22, and the woven fabric layer 23 are all made of a single material of polypropylene. Therefore, it is convenient and simple to recycle, so it is more beneficial to environmental protection.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
