As shown in fig. 1 to 2, the utility model provides an easy-to-form paper bag, which comprises a bag body 1, wherein the surface of the bag body 1 is coated with a waterproof coating, the bag body 1 comprises a first side plate 2 and a second side plate 3, one end of the first side plate 2 is connected with one end of the second connecting plate through a crease line 4, two sides of the first side plate 2 are connected with a third side plate 5 through crease lines 4, two sides of the second side plate 3 are connected with a fourth side plate 6 through crease lines 4, the third side plate 5 is connected with one end of the fourth side plate 6 through a crease line 4, one side of the third side plate 5 is connected with a first connecting plate 7 through a crease line 4, the inner surface of the first connecting plate 7 is bonded with the outer surface of the fourth side plate 6, the outer surface edge of the first side plate 2 or the second side plate 3 is provided with an adhesive tape 8, two parallel crease lines 9 are arranged on the outer surfaces of the first side plate, crease line 9 is parallel to the paper bag opening, adhesive tape 8 bonds with first curb plate 2 or second curb plate 3 surface, the paper bag of this application has the shaping fast, the efficient beneficial effect of packing, directly bond the internal surface of first connecting plate 7 and the external surface of fourth curb plate 6 can accomplish when the paper bag of this application shaping, because be connected for crease line 4 between first connecting plate 7 and the third curb plate 5, have folding function, be favorable to saving storage space like this, open folding part can effectively make the inner space increase when holding article, the waterproof paper bag of this application is paper material, compare the plastic bag that exists on the market now and have more environmental protection's advantage, especially when purchasing the clothes on the net, because the uncontrollable nature outer clothing of logistics environment can get into along with the junction of wrapping bag and soak the clothes, influence customer's purchase experience to the clothes, if because rainy weather express delivery person in order not to let clothing or the article of transportation soak and suspend the transportation or delay the transportation to addressee and express delivery person all be the waste of time cost, therefore the waterproof paper bag of this application can accomplish the effect to inside article dampproofing and waterproofing again under the prerequisite of corresponding environmental protection theory, simple structure, the practicality is strong, convenient to use, put into article from the opening part that is formed by first curb plate 2 and second curb plate 3 one end when using, it needs to explain here, the length of first curb plate 2 can be longer than the length of second curb plate 3, can also be that the length of first curb plate 2 equals the length of second curb plate 3, can also be that the length of first curb plate 2 is shorter than the length of second curb plate 3, when first curb plate 2 and second curb plate 3 length are not equal, adhesive tape 8 sets up in 3 surperficial one side edges of longer first curb plate 2 or second curb plate, when

first curb plate

2 and 3 length of second curb plate are equal, article pack into the container bag after with the first curb plate 2 and the second curb plate 3 of the 1 opening part of the bag body together along crease line 9 that closes on turn over to the 1 bottom direction of the bag body in the bag body 1 outside, further continue to turn over along second crease line 9 again and finally paste adhesive tape 8 and realize the bag closure on the surface of first curb plate 2 or second curb plate 3, for example: when the length of the first side plate 2 is longer than that of the second side plate 3, when the bag is sealed, the first side plate 2 is firstly turned over towards the bottom of the bag body 1 along the adjacent crease line 9, at the moment, the inner surface of the first side plate 2 after being turned over contacts with the outer surface of the second side plate 3, the first side plate 2 and the second side plate 3 are further continued to be turned over along the second crease line 9, finally the adhesive tape 8 is pasted on the outer surface of the second side plate 3, namely, the outer surface of the first side plate 2 and the outer surface of the second side plate 3 are pasted through the adhesive tape 8, the bag sealing is completed, the paper bag effectively plays a role of further water insulation after being turned over twice, and water is prevented from entering the bag from an opening, the waterproof coating is made of paraffin and acrylic ester mixed liquid, the paper packaging material can be recycled, is easy to process, does not produce pollution and the like and becomes a green packaging material which meets the development requirements of, however, the paper and the paperboard are used as the packaging material, and have the defects of poor gas barrier property, moisture barrier property and water resistance, and particularly, as the electric commerce rises to increase express delivery, higher requirements on the water resistance of the paper packaging material are provided, so some documents report methods for coating paper surfaces with polyethylene emulsion and polyvinylidene chloride emulsion for waterproof processing, the methods really have obvious effects on overcoming some defects of the paper packaging material, but other defects also occur simultaneously, for example, when the paper products are treated by the polyvinylidene chloride emulsion, hydrogen chloride gas is easily decomposed under the influence of heat and ultraviolet rays, residual monomers are toxic, and therefore, the paraffin is influenced and limited to a certain extent when the paper products are used for packaging, the paraffin emulsion with good stability is prepared by optimizing an emulsification formula, and then a certain proportion of acrylate waterproof emulsion is compounded, the acrylic emulsion waterproof agent is selected for compounding, so that a good waterproof effect is achieved, the surface of the paper is bright, a continuous waterproof protective film is formed on the surface of the paper, and the acrylic emulsion waterproof agent has a good film-forming property, all films are transparent and bright, the elasticity is good, and the original physical and mechanical properties of the paper cannot be adversely affected, and the paraffin: the melting point 52/54/56/58 and other brands, the glyceryl stearate/oleic acid are all industrial products, the acrylic waterproof agent emulsion is prepared by a coating process, the prepared emulsion waterproof agent is coated on the surface of paper, the prepared emulsion waterproof agent is atomized and then uniformly sprayed on the surface of the paper by a siphon type pressure spray gun, the waterproof coating can be an outer surface coating or an inner surface and an outer surface which are both coated with waterproof coatings, in order to prevent the adhesive tape 8 from being firmly adhered, the waterproof coatings are not arranged at all adhesive positions, in addition, the end surfaces of the opening parts are well hidden inside the first side plate 2 and the second side plate 3 after being folded twice to prevent hand scratch, the formed thickness increases the strength of the opening part of the bag body 1 and can be directly used as a handle, conveniently take and put, the connection of 4 integrated into one piece of crease line is passed through to

first curb plate

2 and 3 one ends of second curb plate for the bottom structure of the bag body 1 is durable more, and this application container bag shaping process is simple, and convenient to use improves packing efficiency.
