Abstract
The utility model relates to a hand drawing plastic film bag which comprises a film bag which is made of temperature materials of high temperature melting bodies and a lining film which is used as a hand drawing window hole of the film bag or a film belt which is used as a hand drawing lifting belt of the film bag. The utility model is characterized in that the regions of the film and the lining film or the film belt, which need to be mutually connected, are all compounded with temperature film layers of low temperature melting bodies. The film bag and the lining film or the film belt need to be glued. The temperature film layers of the low temperature melting bodies of the film bag and lining film or the film belt are in spot gluing connection after the temperature film layers are laminated. The film bag and the lining film or the film belt are in hot melting point gluing connection. The plastic film bag with a partial compounded structure is made of two materials of different melting bodies by using the characteristics of the temperature materials of the melting bodies. Then, the lining film of the same compounded structure is arranged in the region of the film bag, where needs to be reinforced. Low density polyethylene is jointed with a compounded layer surface. Then, the jointed region is in heat melting point gluing connection. Compared with the method of manufacturing the existing similar products, the utility model has the advantages of simple manufacturing procedures and low manufacturing cost.
Description
Technical field
The utility model relates to the polymer film bag, especially a kind of hand drawn plastic film bag of architecture advances.
Technical background
At present, be used for the hand drawn plastic film bag that cargo storage carries and adopt density polyethylene film with high to make usually, this hand drawn plastic film bag comprises two kinds: a kind of is to set up at the sack position of polymer bag film directly to offer the hand of guiding and supporting for the people after strengthening rete and take out mouth; A kind of is with bonding way belt to be installed on the sack edge of polymer bag film.All there is bag film in above-mentioned two kinds of hand drawn plastic film bags and strengthens between the rete, or bonding between bag film and belt.At present, adhering method commonly used has two kinds: a kind of is to stick with glue agent with both bonding connections, and the advantage of this method is bonding firm, and gluing of surfaces is smooth smooth, attractive in appearance, and shortcoming is to need to increase coating process, and complex process can strengthen manufacturing cost undoubtedly; Another kind is the enhancement Layer or the belt of employing and bag film homogeneity, applying one at both binding site then is enough to make its molten sticking temperature that both are bonding, its advantage is that technology is simple, cost is low, shortcoming is that too high molten sticking temperature can make film contraction, wrinkling, influence the attractive in appearance of bag, simultaneously too high molten sticking temperature can influence the intensity of taking out the hand position.
Summary of the invention
The purpose of this utility model is to take out the deficiency that hand formula polymer film bag exists at above-mentioned, and a kind of advantage that both can collect prior art is provided, and can overcome the hand drawn plastic film bag of architecture advances of the defective of prior art existence again.
Hand drawn plastic film bag of the present utility model, comprise: the bag film made from high melt body temperature material and take out the lining form of fenestra enhancement Layer or as the film band of bag film hand-drawing band as bag film sack hand, it is characterized in that: bag film and lining form need connecting portion all to be compounded with low melt body temperature thin layer each other, and the film band can be low melt body temperature film or the high melt body temperature film that is compounded with low melt body temperature film; Point adhesion after the low melt body temperature film aspect of bag film, lining form or the film band of need adhesion is superimposed.
The design principle of the hand drawn plastic film bag of architecture advances of the present utility model is: the characteristic of utilizing different melt body temperature materials, the material of two kinds of different melt body temperatures is made the bag film of part composite construction, to be lining in bag film with the lining form of composite construction then and need strengthen the position, the compound aspect of low density polyethylene (LDPE) fits, can make the temperature of hanging down the fusing of melt body temperature thin layer by the applying position being applied one then, the bag film at applying position and lining form or film interband can take place: low melt body temperature thin layer fusing, make and take place molten stickingly between two films at the position that fits, molten sticking phenomenon can not take place in that same temperature is next between the high melt body temperature thin layer.
The hand drawn plastic film bag of the utility model architecture advances, design science, rational in infrastructure, to compare with existing like product, its biggest advantage is: simplified production process greatly, reduced manufacturing cost.
The concrete structure of the hand drawn plastic film bag of the utility model architecture advances is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the hand drawn plastic film bag schematic diagram of architecture advances;
Fig. 2 is the hand drawn plastic film bag A position enlarged diagram of architecture advances shown in Figure 1;
Fig. 3 is the hand drawn plastic film bag schematic diagram of another kind of architecture advances;
Fig. 4 is the hand drawn plastic film bag B position enlarged diagram of improvement shown in Figure 3.
Embodiment 1: can be clear that from Fig. 1, this is a kind ofly directly to offer the hand drawn plastic film bag that hand is taken out the architecture advances of fenestra in bag film sack lower edge, comprise: bag film 1 that high density polyethylene (HDPE) is made and enhancement Layer lining form 2, sack position around bag film 1 is compounded with low density polyethylene layer 3 (see figure 2)s, and enhancement Layer lining form 2 also is compounded with low density polyethylene layer 4; Enhancement Layer lining form 2 lining is put at bag film 1 sack position, describedly is superimposed with enhancement Layer lining form 2 low density polyethylene layers 4 at bag film 1 low density polyethylene layer 3, and puts adhesion 5 in molten adhesion mode.Offer the fenestra of taking out as hand 6 at the bag film 1 sack position that is lined with enhancement Layer lining form 2 then.
Embodiment 2: can be clear that from Fig. 3, this is a kind of hand drawn plastic film bag that is provided with the architecture advances of belt, comprise: the bag film 1 that high density polyethylene (HDPE) is made and as the film band 7 of belt, sack position around bag film 1 is compounded with low density polyethylene layer 3, and the film band 7 that is used as belt also is compounded with low density polyethylene layer 4 (see figure 4)s; The two ends of film band 7 are superimposed at bag film 1 sack edge, describedly are superimposed with film band 7 low density polyethylene layers 4 and put adhesion 5 at bag film 1 low density polyethylene layer 3.
