Abstract
The utility model discloses an easy-tearing packaging bag comprising a bag body formed by heat-sealing a composite packaging film, wherein the composite packaging film is provided with easy-tearing lines which are formed on the front and the back sides of the bag body in positions on the same line; the composite packaging film is formed by compounding a polyethylene glycol terephthalate film layer for reinforcing and a polyethylene film layer for heat-sealing; disconnected damaging nicks are formed on the polyethylene glycol Terephthalate film layer; and the easy-tearing lines are formed by the disconnected damaging nicks. The easy-tearing packaging bag has a favorable sealing effect and an excellent service performance, and can be torn with a very small force along the easy-tearing lines with the notches to form a regular opening torn along nicking lines; besides, the hole-shaped nicks are formed by punching with a punch die provided with comb tooth-shaped cutting teeth, and all the nicks on each easy-tearing line can be formed at one step by punching with the punch die, which generates no bad odor, is more environment-friendly and has a higher production efficiency.
Description
Technical field
The utility model belongs to the soft package technology field, is specifically related to a kind of easy-tear type packaging bag.
Background technology
Traditional common flexible packaging film is not easy to be torn in use, even and after tearing, it is smooth that the place of tearing can not keep, cause using very inconvenient, also influence impression.
At present, occurred having the flexible packaging film of easy-torn line on the market, for example patent documentation CN1608951Y discloses a kind of method for making of soft packaging bag tearable mouth, and this method may further comprise the steps:
(1), designed patterns is input in the computer system; (2) control laser cutting system with computer system; (3) laser beam irradiation that described laser cutting system is generated is to the one side of soft packaging bag diaphragm seal, and described laser beam carves or cut into the line of weakness of corresponding pattern moulding in the one side of soft packaging bag diaphragm seal according to designed pattern; (4) described tearable mouth is formed according to line of weakness.
There is following weak point in this kind method: laser machine price is higher, and the manufacturing line infusion of financial resources is many; Because in most of technologies, film direction of travel and line of weakness direction be in same direction, so laser head must move the line of weakness that just can complete behind the certain distance, this rate travel is slower, loses time reduction production efficiency; The principle of laser beam indentation is to utilize the high temperature sintering film and form indentation in fact, so can produce niff, causes large quantity of exhaust gas.
The utility model content
It is higher and have an easy-tear type packaging bag that is prone to tear effect that the purpose of the utility model provides a kind of production efficiency.
Realize the utility model technical scheme be: a kind of easy-tear type packaging bag, comprise the bag that forms by the composite package film heat-sealing, said composite package film is provided with easy-torn line at the same straight line of bag tow sides place; It is characterized in that: said composite package film is composited by polyethylene terephthalate rete that is used to strengthen and the polyethylene film layer that is used to seal; Said polyethylene terephthalate layer is provided with the destructive indentation of discontinuous, and forms easy-torn line at this destructiveness indentation place.
Between said polyethylene terephthalate rete and the polyethylene film layer, also be compounded with aluminium foil layer.
Said destructive indentation is the poroid indentation that on the polyethylene terephthalate rete, forms through the die-cut mode of machinery.
The utlity model has positive effect: (1) the utility model since the higher polyethylene terephthalate rete of intensity by the poroid indentation in the die-cut place of the cutting on the punch die; The polyethylene film layer of effect is torn in the more weak influence hardly of intensity and aluminium foil layer is then complete remains; Both had good sealing effectiveness; Can just can tear with very little power again, form the regular shape opening of tearing along line of weakness, have excellent in-use performance along the easy-torn line that is provided with indentation.In addition; The utility model no longer adopts the mode of laser light velocity scorification to make indentation; But adopting the die-cut pet film of punch die that is provided with the cutting of broach shape to obtain poroid indentation, all indentations at every easy-torn line place can be accomplished through the punch die one-step punching, and free from extraneous odour produces; Comparatively environmental protection, and production efficiency is higher.

Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is a kind of cutaway view of used first kind of composite package film in the easy-tear type packaging bag shown in Figure 1;
Fig. 3 is a kind of cutaway view of used second kind of composite package film in the easy-tear type packaging bag shown in Figure 1.
Reference numeral is: polyethylene terephthalate rete 1, polyethylene film layer 2 is multiple, indentation 3, aluminium foil layer 4, composite package film 5, bag 6, easy-torn line 7.
The specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown first kind of specific embodiment of utility model, and wherein Fig. 1 is a kind of structural representation of the utility model; Fig. 2 is a kind of cutaway view of used first kind of composite package film in the easy-tear type packaging bag shown in Figure 1.
Present embodiment is a kind of easy-tear type packaging bag, sees illustrated in figures 1 and 2ly, comprises the bag 6 that is formed by composite package film 5 heat-sealing, and said composite package film is provided with easy-torn line 7 at the same straight line of bag tow sides place; Said composite package film is composited by polyethylene terephthalate rete that is used to strengthen 1 and the polyethylene film layer 2 that is used to seal; Said polyethylene terephthalate layer is provided with the destructive indentation 3 of discontinuous, and forms easy-torn line at these destructiveness indentation 3 places.
In the present embodiment, said destructive indentation is the poroid indentation 3 that on the polyethylene terephthalate rete, forms through the die-cut mode of machinery.
(embodiment 2)
Fig. 3 is a kind of cutaway view of used second kind of composite package film in the easy-tear type packaging bag shown in Figure 1, has shown second kind of specific embodiment of the utility model.
Present embodiment and embodiment 1 are basic identical, and difference is: between said polyethylene terephthalate rete 1 and the polyethylene film layer 2, also be compounded with aluminium foil layer 4.
The foregoing description 1 and 2 has the following advantages: because the higher polyethylene terephthalate rete of intensity is by the poroid indentation in the die-cut place of the cutting on the punch die; The polyethylene film layer of effect is torn in the more weak influence hardly of intensity and aluminium foil layer is then complete remains; Both had good sealing effectiveness; Can just can tear with very little power again, form the regular shape opening of tearing along line of weakness, have excellent in-use performance along the easy-torn line that is provided with indentation.In addition; The utility model no longer adopts the mode of laser light velocity scorification to make indentation; But adopting the die-cut pet film of punch die that is provided with the cutting of broach shape to obtain poroid indentation, all indentations at every easy-torn line place can be accomplished through the punch die one-step punching, and free from extraneous odour produces; Comparatively environmental protection, and production efficiency is higher.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
