Abstract

The utility model discloses an integrated plastic open and close strip provided with a tearing strip and a packaging bag thereof. A male strip and a female groove which can be meshed are arranged on the open and close strip, the tearing strip is arranged on the open and close strip which is an integrally formed plastic strip, the middle of the plastic strip is folded to form two surfaces, the male strip and the female groove are arranged in the relative positions of the two surfaces of the plastic strip respectively; the tearing strip is arranged above the female groove or the male strip; and bulges are symmetrically arranged at the upper end and the lower end of the tearing strip. The integrated open and close strip breaks the limitation of a traditional open and close strip consisting of one male strip and one female groove, and the leak tightness is better; besides, the open and close strip is no required to be opened when the packaging bag is subjected to product filling, so that the open and close strip as well as the male strip and the female groove cannot be polluted, and the service life of the open and close strip is prolonged; and bulges are arranged at the upper side and the lower side of the tearing strip and have the guiding effect during tearing, accordingly, the bag body is torn easily, the probability of local tearing or total tearing of the open and close strip is low, the probability of defective products is reduced, and the cost is saved.

Description

One plastic open-close strip and packaging bag thereof that band is torn bar

Technical field

The utility model relates to plastic wrapping product technical field, and specifically a kind of band is torn one plastic open-close strip and the packaging bag thereof of bar.

Background technology

Being used for the plastic package material of the various article such as packaged food, medicine, medical supplies, industrial goods, groceries mostly adopts a kind of packaging bag with plastic open-close strip.It is lightweight that reason is that it has, and compliance is good, cheap, can Reusability etc. plurality of advantages.Plastic open-close strip is comprised of male pawl and female groove, and male pawl and the interlock mutually of female groove can freely openables, and this packaging bag with open-close strip need to be carried out involution and make packaging bag sealing the top of plastic open-close strip.During Kaifeng, open-close strip top need to be torn together with whole bag.Traditional mode is: the both sides in packaging bag arrange breach, from indentation, there, tears whole packaging bag and breaks a seal.This mode of tearing is obviously arbitrarily, and the trend of tearing port can not be determined.In addition, for the material of some plastic packaging bag, be also difficult to tear.For above-mentioned deficiency, people arrange Kaifeng rope on the part of open-close strip, by tractive, broken a seal rope and bag main body is torn.But because Kaifeng rope is arranged on the part of plastic open-close strip, when utilizing Kaifeng rope to tear, must or all tear the local of plastic open-close strip simultaneously, also still be not easy to tear, especially for old man or children.People had found out a kind of easy tear tape afterwards, and an easy tear tape is set on packaging bag and open-close strip, and easy tear tape is torn bag main body together, in order to be more convenient for, tore, and at the two ends of easy tear tape, guide plate were set.But above-mentioned open-close strip is also split, male bar and female groove be located at respectively two upper, two are heat seals respectively or are adhesive on bag, this mode operation is comparatively loaded down with trivial details and sealing effectiveness is not good enough.

Utility model content

In order to overcome above-mentioned deficiency, the one plastic open-close strip that the utility model provides a kind of band to tear bar, also comprises the packaging bag of applying this open-close strip in addition.Open-close strip of the present utility model is the plastic strip of one, and plastic strip is provided with male bar and female groove, and after plastic strip doubling, male bar and female groove can interlocks, and this mode better tightness, has reduced the generation of seepage.

The technical solution of the utility model is achieved in that is with the one plastic open-close strip of tearing bar, on open-close strip, there are a pair of male bar and female groove that can interlock, and be provided with and tear bar, described open-close strip is integrated plastic strip, in the middle of plastic strip, be folded to form two sides, male bar and female groove are located at respectively the relative position on plastic strip two sides, the top of female groove or male bar is established and is torn bar, the upper and lower side of tearing bar is symmetrical arranged projection, and tear between bar and projection and leave gap, when being heat sealed to bag, open-close strip can not make to tear bar and open-close strip becomes one, more easily bag is broken a seal.

For the ease of plastic strip doubling, groove is established in the doubling position of described plastic strip.

The upper and lower sides of described female groove or male bar arranges anti-skidding rib, and anti-skidding rib with tear bar homonymy.

Band is torn the packaging bag of the one plastic open-close strip of bar, and open-close strip is arranged on packaging bag inside, and the male bar of open-close strip becomes interlocking pattern with female groove.

The face of tearing bar place of described open-close strip is by sealing or being adhesive on bag.

The beneficial effects of the utility model are: one open-close strip of the present utility model has been broken traditional open-close strip being comprised of a male bar and a female groove, and better tightness has reduced Seepage.In this kind of packaging bag of production and application, carry out product in addition and without open-close strip is opened, can not pollute open-close strip when filling when filling, the male bar of open-close strip and female groove can not affect because of pollution closure function like this, thereby have increased the service life of open-close strip.Tear the upper and lower both sides of bar and respectively have a projection, while tearing easy tear tape, this projection play the guiding role, can by tearing bar, together bag be broken a seal easily, and concerning children old man, tearing this easy tear tape is also very easy to, nor easily there is the situation that open-close strip is local or all tear, reduced the chance of occurrence of defective products, thereby provided cost savings.
