As shown in figure 1, the utility model provides a waterproof paper bag, which comprises a bag body 1, the surface of the bag body 1 is provided with a waterproof coating, the outer surface of one side of the opening part of the bag body 1 is provided with an adhesive tape 2, the opening part of the bag body 1 is provided with two first crease lines 3 parallel to the opening end of the bag body 1, the opening part of the bag body 1 is sequentially folded along the two first crease lines 3 towards the bottom end direction of the bag body 1, the adhesive tape 2 is bonded on the outer surface of the bag body 1, the waterproof paper bag is made of paper materials, has the advantage of environmental protection compared with the plastic bags existing on the market, especially when purchasing clothes on line, because the uncontrollable outerwear in the logistics environment can wet the clothes along with the entering of the connecting part of the packaging bag in rainy day, the purchasing experience of the clothes of customers is influenced, if the time and cost are wasted for the addressee and the courier because the courier stops the transportation or delays the transportation to prevent the clothes or the transported articles from being soaked, the waterproof paper bag of the application can achieve the waterproof and moistureproof effects on the internal articles on the premise of corresponding environmental protection idea, has simple structure, strong practicability and convenient use, firstly puts the articles into the bag body 1 along the opening, then turns over the opening of the bag body 1 pasted with the adhesive tape 2 along the first crease line 3 close to the opening of the bag body 1 towards the bottom direction of the bag body 1, at the moment, the outer surface of the same side of the opening of the bag body 1 is contacted because of turning over along the first crease line 3, further turns over the opening of the turned-over bag body 1 towards the bottom of the bag body 1 along the other first crease line 3, and finally leads the corresponding position of the opening of the bag body 1 provided with the adhesive tape 2 and the outer surface of the bag body 1 to be bonded through the, set up two first crease lines 3 and turn over the book to 1 bottom of the bag body for 1 opening part of the bag body that will be provided with adhesive tape 2 for the sake of convenience, and further play waterproof effect, turn over the entering that twice can effectual prevention moisture, turn over the intensity that has increased 1 opening part of the bag body after turning over twice at 1 opening part of the bag body simultaneously and make the sack can not damage easily, in addition 1 opening part of the bag body can also make the outstanding book portion of turning over of 1 surface of the bag body can not scratch the hand after having turned over both sides, can act as the handle when needing and use, what need explain here is: the opening end of the bag body 1 can be a parallel and level opening end, or one side is long and the other side is short, at the moment, the adhesive tape 2 is arranged on the outer surface of the long side, for the convenience of understanding, the bag body 1 comprises a front surface and a back surface, the front surface of the opening end of the bag body 1 is short and the back surface is long, the adhesive tape 2 is arranged on the outer surface of the back surface, one first crease line 3 can be arranged on the back surface and is parallel and level with one end of the front surface, the other first crease line 3 can be arranged on the outer surface of the bag body 1 and is positioned between the bottom of the bag body 1 and one first crease line 3, when a product is

grown part is contacted with the outer surface of the front surface at the moment, the folded, finally, the outer surface of the part growing out at the opening is bonded with the outer surface of the front side through the adhesive tape 2, the waterproof coating is made of mixed liquid of paraffin and acrylic ester, the paper packaging material becomes a green packaging material meeting the development requirements of times with excellent performances in multiple aspects, recoverability, easy treatment, no pollution and the like, however, the paper and the paperboard serving as the packaging material also have the defects of poor air resistance, moisture resistance and waterproofness, particularly, express delivery increment is increased along with the growth of electric merchants, higher requirements are provided for the waterproofness of the paper packaging material, so that methods for coating paper surfaces with polyethylene emulsion and polyvinylidene chloride emulsion for waterproof processing are successively reported in some documents, the methods can overcome some defects of the paper packaging material and really achieve obvious effects, but other defects can also occur, such as the treatment of paper products with the polyvinylidene chloride emulsion, the application adopts paraffin as a main raw material, prepares paraffin emulsion with good stability by optimizing an emulsification formula, then compounds a certain proportion of acrylate waterproof emulsion to obtain excellent waterproof performance after treating paper products, and obtains excellent waterproof performance after treating the paper products by singly using the paraffin emulsion to carry out waterproof treatment on the paper products, although the waterproof performance can be improved, the effect is not ideal, so the acrylate emulsion waterproof agent is selected for compounding to obtain better waterproof effect, the paper has good waterproof effect, the surface of the paper is bright, a layer of continuous waterproof protective film is formed on the surface of the paper, and the acrylic emulsion waterproof agent has good film forming property, all films are transparent and bright, have good elasticity, do not have adverse effects on the original physical and mechanical properties of paper, and paraffin: the melting point 52/54/56/58 and other brands and the glyceryl stearate/oleic acid are all industrial products, the acrylic waterproof agent emulsion is prepared by coating the prepared emulsion waterproof agent on the surface of paper by adopting a coating process, and the prepared emulsion waterproof agent is uniformly sprayed on the surface of the paper after being atomized by a siphon type pressure spray gun through infrared heat drying or pressure roller heating drying or adopting a spraying process, wherein the waterproof coating can be an outer surface coating or an inner surface and an outer surface which are both coated with waterproof coatings, and in order to prevent the adhesive tape 2 from being firmly adhered, no waterproof coating is arranged at all viscose positions; the waterproof paper bag can be made of wood pulp paper, recycled paper, composite paper, and derived white cardboard, coated paper, white kraft paper, natural color kraft paper, grey-bottom white cardboard paper, black cardboard, preferably natural color kraft paper, the paper bag can be recycled and reused for papermaking after the life cycle is completed, the waterproof layer and the adhesive both belong to water-based solvents, can be dissolved in water in the pulping process, and are filtered through water circulation, no influence is generated in the papermaking manufacturing process of a conventional paper machine, forest protection is effectively reduced, and waste of resources is avoided.
