Abstract
The utility model discloses a two-way easy not disconnected wrapping bag that tears, it includes: left and right easy-to-tear openings, a heat sealing strip, an upper layer film, a middle interlayer blocking film, a lower layer film and an inner cavity opening of the packaging bag. The upper layer film, the middle interlayer blocking film and the two side edges of the lower layer film are sealed together to form two side walls of the packaging bag, and the left easy-tear opening and the right easy-tear opening are formed in one end of each of the two side walls. According to the utility model discloses a wrapping bag blocks the membrane structure through setting up middle intermediate layer in both sides for it has increased one deck separation film between the two-layer packing of lower floor's membrane and its upper strata membrane. When the packaging bag is torn from one side to the other side, resistance is generated due to the film added in the middle interlayer, so that the packaging bag is easy to tear in two directions and is not separated.
Description
Technical Field
The utility model relates to a wrapping bag, in particular to two-way easy-tear is from disconnected wrapping bag.
Background
The existing object packaging bags, especially food packaging bags, are usually provided with easy-to-tear openings, but the openings are all torn to the bottom. When the pre-packaged article needs to be taken out, the packaging bag is divided into two parts after the packaging bag is torn, and two parts of garbage can be generated after the article is taken out. Especially when used in small spaces such as cabins, space flight and aviation cabs, not only is the potential impact on environmental pollution doubled, but its use is also limited due to environmental particularities.
In order to solve the defect that the packaging bag is divided into two after the opening of the packaging bag is torn, the patent application with the application number of 201210131841.7 discloses an easy-to-tear non-separating packaging bag, the structure of which comprises the packaging bag, an easy-to-tear opening and a hanging hole, wherein the easy-to-tear hole is arranged on the edge of one side of the packaging bag, the hanging opening is positioned on the edge of the corresponding easy-to-tear opening of the packaging bag at the other side of the packaging bag, and the hanging opening is circular. After adopting above-mentioned structure, can prevent that the wrapping bag from tearing the back and separating, but it also can only realize the unilateral mouth of tearing, can't realize two-way tearing the wrapping bag at upper and lower bag inseparable.
In addition, the patent application with the application number of 201220187292.0 discloses a novel packaging bag, and fig. 1 shows a structural schematic diagram of the novel packaging bag. This novel wrapping bag includes: the bag comprises a body 101 and a hand-held hole 102, wherein the bottom of the body 101 is provided with a bag bottom 105, a zipper 104 is arranged below the hand-held hole 102, a laser strip 103 which can be torn is arranged on the front surface of the bag body above the zipper 104, the front surface and the rear surface of the packaging bag body 101 above the laser strip 103 are pressed, and the front surface and the rear surface of the bag body 101 below the laser strip 103 form a space which can contain contents. According to the design, the laser strip 103 is arranged above the zipper 104 of the packaging bag and below the carrying hole 102, so that after the laser strip 103 is torn off in use, the upper part and the lower part of the packaging bag are not separated, and the carrying hole can still be used.
By adopting the prior art, although the packaging bag can be prevented from being separated after being torn, and the upper part and the lower part of the packaging bag can not be separated after being torn in one direction, the packaging bag can only be torn in one direction and cannot be separated, and the upper part and the lower part of the packaging bag can not be separated after being torn in two directions.
Disclosure of Invention
In view of the above insufficiency of the prior art, the utility model discloses on current packaging technique basis, utilize two sides intermediate layer to block the membrane structure, increase the one deck film between two-layer packing. When the packaging bag is torn from one side to the other side, resistance is generated due to the film added in the middle interlayer, so that the packaging bag is easy to tear in two directions and is not separated.
In order to achieve the above object, the utility model provides a two-way easy-tear is from disconnected wrapping bag, it includes:
left and right easy-tear openings 201, heat-seal bar 202, upper film 203, middle interlayer barrier film 204, lower film 205 and inner cavity opening 206 of the packaging bag. Wherein, left and right easy tear mouth 201 establishes respectively on the edge of wrapping bag both sides, and the sack can conveniently be opened through easy tear mouth position effectively to easy tear mouth position, takes out the wrapping bag content.
Preferably, the middle interlayer barrier film 204 is positioned between the upper film 203 and the lower film 205 on both sides of the packaging bag, and is sealed with the upper film 203 and the lower film 205 by heat sealing, and the width thereof is slightly larger than the heat sealing area. The upper film 203, the middle layer barrier film 204 and the lower film 205 are connected together by heat sealing to form a side wall of the package to form a two-sided heat seal bar 202, and the two-sided heat seal bar 202 and the bottom heat seal bar 202 together form a three-sided seal of the package.
The opening 206 of the inner cavity of the packing bag is formed at one end of the packing bag, the side walls at two sides of the end formed with the opening 206 of the inner cavity of the packing bag are respectively provided with a left easy-tearing opening 201 and a right easy-tearing opening 201, and after the filling of the content is completed when the heat sealing is not carried out, the content can be sealed in the packing bag through a sealing machine.
Alternatively, the upper film 203, the interlayer blocking film 204, and the lower film 205 are joined together by press fitting.
The utility model has the advantages that: when the bag is torn along the easy-tear opening on one side and is extended to the heat-seal strip on the opposite side, the middle interlayer blocking film can prevent the opening from being further extended, thereby realizing the effect of no disconnection. Similarly, when the bag is torn from the easy-tear opening on the other side, the middle interlayer barrier film on the opposite side can also realize the effect of non-separation. The middle interlayer barrier film does not influence the tearing of the packaging bag from the easy-to-tear opening. Therefore, according to the utility model discloses a structural design when can conveniently tearing the wrapping bag opening, prevented again that the wrapping bag is divided into two, when especially using in the space environment, effectively reduced wrapping bag rubbish quantity, alleviateed environmental pollution.
