Abstract
The utility model relates to a kind of plastic packaging bag with sealing band, comprise bag and the sealing band being arranged on bag oral area, described sealing band comprises two fixed edges fixing with the difference hot pressing of bag both sides, two fixed edges are arranged respectively male pawl and female groove, the two ends of described fixed edge arrange through hole, the through male pawl of described through hole and female groove.Use structure of the present utility model, after heat-sealing, sealing intensity can strengthen, and hermetic unit planeness can improve, and product thermal contraction distortion is little, can solve product surface unfairness, easily bubble in surface, thermal contraction is large, the easy problem such as distortion.
Description
Technical field
The utility model relates to a kind of plastic bag, especially a kind of plastic packaging bag with sealing band.
Background technology
Mostly use the usually general transparent plastic bag with sealing strip at present, the sealing band of this kind of plastic bag is made up of raised line and groove, hot pressing is in the sack both sides of plastic bag respectively, with hand, sack can be sealed by compressing into draw-in groove bar by bayonet strip, as long as but pull outward with the upper limb of hand-held firmly sealing strip, sealing strip can be opened.This plastic bag can be opened and close many times, although concavo-convex bar is not fragile, but the bonding between sealing band and plastic bag is often firm not, after after a while, sealing band and plastic bag easily come off, and cause plastic bag to seal again, the phenomenon such as becoming damp and rotten easily appears in product, pollute, oxidation, affect the quality of product, cause waste.And this sealing band is when sealing with plastic bag, and heat-sealing place is wrinkling deformation often, plastic bag seems and unfairness also easily causes sealing band and plastic bag to depart from simultaneously.
If the raised line of sealing band and groove fit is too tight, larger strength is needed when opening, often easily make heat-sealing place of plastic bag and sealing band be torn like this, and if the too pine of raised line and groove fit, sealing band is easily opened when the activity that plastic bag is in-built collides by article.Need a kind of special structure of design, the strength that user is torn by hand needed for sealing band from a certain special angle is not too large, and in bag, article are not easy sealing band to collide to open.
Utility model content
Problem to be solved in the utility model is to provide the plastic packaging bag with sealing band that a kind of hermetic unit planeness is high, hermetic unit intensity is high, product thermal contraction distortion is little.
For solving the problems of the technologies described above, plastic packaging bag with sealing band of the present utility model, comprise bag and the two panels sealing band being arranged on bag oral area, described sealing band comprises two fixed edges fixing with the difference hot pressing of bag both sides, two fixed edges are arranged respectively male pawl and female groove, the two ends of described fixed edge arrange through hole, the through male pawl of described through hole and female groove, the two panels sealing band heat-sealing of through hole.
The shape of described through hole is one or more the combination in rhombus, oblong, ellipse, circle, butterfly shape, aciculiform, yi word pattern.
Described female groove comprises left side hook, right side hook and middle raised line, and described public pawl comprises left pawl and right pawl, forms the cavity matched with described middle raised line between left pawl and right pawl.Use this structure, the strength that user is torn by hand needed for sealing band from a certain special angle is not too large, and in bag, article are not easy sealing band to collide to open.
On described fixed edge, male pawl and female groove both sides arrange the burr being parallel to male pawl and female groove.Burr plays the effect of reinforced rib, makes fixed edge be not easy to be torn.This structure also can allow the intensity of sealing band and plastic bag heat seal better, more smooth, is not easy to come off.
On described fixed edge, male pawl and female groove both sides respectively arrange two burrs.
Use structure of the present utility model, after heat-sealing, sealing intensity can strengthen, and hermetic unit planeness can improve, and product thermal contraction distortion is little, solves product surface unfairness, easily bubbles in surface, thermal contraction is large, the easy problem such as distortion.

Detailed description of the invention
As shown in Figure 1, plastic packaging bag with sealing band of the present utility model, comprise bag 1 and the left and right two panels sealing band being arranged on bag 1 oral area, sealing band comprises two fixed edges 2 fixing with the difference hot pressing of bag 1 both sides, two fixed edges 2 arrange male pawl 3 and female groove 4 respectively, the two ends of fixed edge 2 are arranged through hole 5, male pawl 3 punches with the plastic skin of female groove 4 together with neighbouring fixed edge, the through male pawl 3 of through hole 5 and female groove 4.As shown in Figure 2, when plastic bag and sealing band being sealed, on the position arranging through hole 5, left and right two panels sealing band heat also can be enclosed in together, the part in the middle of sealing band is then normally opened, the part of shaded side and the heat-sealing of two panels right-left seal bar in Fig. 2.Because through hole 5 has been opened at sealing band two ends, when sealing band and plastic bag seal, the bubble produced between sealing band and plastic bag can overflow from through hole, make to seal between rear sealing band and plastic bag and no longer include bubble, solve product surface unfairness, easily bubble in surface, thermal contraction is large, the easy problem such as distortion.The shape of through hole 5 is one or more the combination in the various shapes such as rhombus, oblong, ellipse, circle, butterfly shape, also can adopt other shapes such as triangle or yi word pattern.
As shown in Figure 3, on fixed edge 2, male pawl 3 and female groove 4 both sides respectively arrange the burr 7 that two are parallel to male pawl 3 and female groove 4.Burr 7 plays the effect of reinforced rib, makes fixed edge 2 be not easy to be torn.This structure also can allow the better, more smooth of sealing band and plastic bag heat seal strength, is not easy to come off.
As shown in Figure 4 and Figure 5, female groove 4 comprises left side hook 4a, right side hook 4b and middle raised line 4c, and public pawl 3 comprises left pawl 3a and right pawl 3b, forms the cavity 6 matched with described middle raised line 4c between left pawl 3a and right pawl 3b.Use this structure, the strength that user is torn by hand needed for sealing band from a certain special angle is not too large, and in bag, article are not easy sealing band to collide to open.
The above, only to preferred embodiment of the present utility model, not do other forms of restriction to the utility model, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equal change.Everyly do not depart from the utility model plan content, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and remodeling, all drop in protection domain of the present utility model.
