Description
Technical field
The utility model relates to the packaging bag field, particularly a kind of heat-sealing mouthful paper bag.
Background technology
At present, the heavy paper bag packing that surpasses 20KG (kilogram) all is the mode that adopts sewing machine to sew up and down and seal, as shown in Figure 1, be packed into the interior thorax 21 of paper bag when material after, seal in oral area 22 sewing of paper bag with sewing machine, the bottom 23 of paper bag is just to have sealed with the sewing machine suture when paper bag is made.This paper bag is because the outwardness of pin hole just will certainly have following problem: one, the risk of leaking material is arranged; Two, bag gas leakage and material taint of odour; Three, material moisture-sensitive; Thereby the fiber that four, sewing thread is arranged is sneaked into the risk of material contaminated material; Five, the inefficiency of can material.
The utility model content
Technical problem to be solved in the utility model provides a kind of heat-sealing mouthful paper bag, it realizes imporosity, does not leak material, air tight, material can not make moist, do not have the foreign matter pollution risk.
Technical problem to be solved in the utility model provides a kind of heat-sealing mouthful paper bag, a heat-sealing mouthful paper bag comprises bag, the sack oral area, the sack bottom, sack oral area and sack bottom lay respectively at the top and bottom of bag, it is characterized in that, a heat-sealing mouthful paper bag also comprises the ground floor paper, second layer paper, three-ply paper is opened, plastic membranous layer, hot melt glue, the bonding position of ground floor paper, the bonding position of second layer paper, three-ply paper is opened bonding location, bag, the sack oral area, the sack bottom is by the ground floor paper, second layer paper, three-ply paper is opened with the plastic membranous layer bonding and is formed, the two ends of ground floor paper are in the bonding position of ground floor paper bonding, the two ends of second layer paper are in the bonding position of second layer paper bonding, three-ply paper Zhang Zaidi three-ply paper is opened the bonding location bonding, the height of ground floor paper is greater than the height of second layer paper, the height that the height of second layer paper is opened greater than three-ply paper, hot melt glue is coated in the ground floor paper, the difference position of the height that second layer paper and three-ply paper are opened, plastic membranous layer is bonded in the inside that three-ply paper is opened.
Preferably, a described heat-sealing mouthful paper bag also comprises flanging, and flanging is positioned at the side of bag.
Positive progressive effect of the present utility model is: the utility model is because the paper of sack oral area is bonding fully layer by layer, airtight fully, thereby reach the imporosity, do not leak material, air tight, material can not make moist, do not have the foreign matter pollution risk, bag is basic one-tenth cuboid behind the can material, heap bag is neat, the needs of the easy and suitable large-scale industrial production of heating sealing operation.
Description of drawings
Fig. 1 is the structural representation of traditionally on paper packaging bag.
Fig. 2 is the structural representation of the utility model heat-sealing mouthful paper bag.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 2, the utility model heat-sealing mouthful paper bag comprises bag 1, flanging 2, sack oral area 3, hot melt glue 4, ground floor paper 5, second layer paper 6, three-ply paper opens 7, plastic membranous layer 8, sealing line 9, the bonding position 12 of ground floor paper, the bonding position 13 of second layer paper, three-ply paper is opened bonding location 14, sack bottom 18, bag 1, sack oral area 3, sack bottom 18 is by ground floor paper 5, second layer paper 6, three-ply paper open 7 and plastic membranous layer 8 bonding form, the two ends of ground floor paper 5 are in the bonding position of ground floor paper 12 bondings, the two ends of second layer paper 6 are in the bonding position of second layer paper 13 bondings, three-ply paper is opened 7 and is opened bonding location 14 bonding at three-ply paper, it is ground floor paper 5, second layer paper 6, three-ply paper is opened 7 and is stacked successively and three-ply paper opens 7 at outermost, 1 one-tenth tubular of bag; In addition, at sack oral area 3 places as can be seen, the height of ground floor paper 5 is greater than the height of second layer paper 6, the height of second layer paper 6 is opened 7 height greater than three-ply paper, be ground floor paper 5, second layer paper 6, three-ply paper open 7 form one stepped, hot melt glue 4 (dash area among the figure) is coated in the difference position that ground floor paper 5, second layer paper 6 and three-ply paper are opened 7 height.Three-ply paper is opened the agent structure that has constituted sack and the packaging intensity of sack is provided, but paper has certain moisture, cause being seated in the material moisture absorption wherein easily, therefore increase one deck plastic membranous layer 8, plastic membranous layer 8 is bonded in three-ply paper and opens 7 inside, and it is identical that the shape of plastic membranous layer 8, size and three-ply paper are opened 7 shape, size.Plastic membranous layer 8 can completely cut off moisture fully; plastic membranous layer 8 protection materials are nonhygroscopic; the material of plastic membranous layer can be HDPE (High-density polyethylene; high density polyethylene (HDPE)), also can be LDPE (L0w-density polyethylene, low density polyethylene (LDPE)) or other plastic film materials.Sack oral area 3 and sack bottom 18 lay respectively at the top and bottom of bag 1, and sack bottom 13 just adds heat bonding before dispatching from the factory.Flanging 2 is positioned at the side of bag 1, the M type that is shaped as of flanging 2, this flanging has been arranged after, sack has loaded and has formed behind the material rectangular-shapedly naturally, pile easily and firm is saved the space, is convenient to the transportation of hit-gain trust dish.Sealing line 9 is positioned at the below of hot melt glue 4 and certain distance is arranged between the two.
Use the heat-sealing pocket period of the day from 11 p.m. to 1 a.m, at first draw back plastic membranous layer 8, stretching-bag rim of the mouth portion, material pours into the centre of plastic membranous layer 8.After material was loaded into bag 1 and finishes, sack oral area 3 was along 9 pairs of bendings of sealing line, and clamp with heating tool, and is just bonding firmly the paper layer by layer of sack oral area after hot melt glue 4 fusings of oral area.Because the paper of sack oral area is bonding fully layer by layer, airtight fully, thereby reach the imporosity, do not leak material, air tight, material can not make moist, do not have the foreign matter pollution risk, bag is basic one-tenth cuboid behind the can material, heap bag is neat, the needs of the easy and suitable large-scale industrial production of heating sealing operation.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only are casehistorys, under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
