Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bags, in particular to a pearl cotton packaging bag. Background Art
[0002] Pearl cotton packaging bags are made of pearl cotton or polyethylene foam as the main material. Pearl cotton is made of countless independent bubbles produced by physical foaming of low-density polyethylene resin, which overcomes the shortcomings of ordinary foamed rubber such as fragility, deformation and poor recovery. The pearl cotton is then composited with PE film by hot pressing and other processes to make the bag film layer of the pearl cotton packaging bag. It has many advantages such as waterproof and moisture-proof, impact resistance, sound insulation, heat preservation and environmental protection. It is widely used in the protective packaging of electronic products, instruments, handicrafts, household appliances, hardware tools and other products in various fields.
[0003] The structure of the pearl cotton packaging bag is simple, generally consisting of only two film layers. Although it is compounded with PE film, its overall tensile and tear resistance properties are poor, and the sealed edges are relatively fragile. When the user opens the bag to put the items to be packaged into the bag, it is easy to tear the sealed edges at both ends of the bag. When the bag is stretched open by the items contained, the sealed edges at both ends are also easy to crack downwards, causing damage to the bag. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a pearl cotton packaging bag to solve the above problems.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0006] The utility model provides a pearl cotton packaging bag, which comprises a first bag surface and a second bag surface opposite to each other, wherein the first bag surface and the second bag surface constitute a bag body with a bag opening at the top. Plastic support strips are fixed on the first bag surface and the second bag surface, and the two plastic support strips extend along the edges of the bag opening on the corresponding surfaces respectively, and the two plastic support strips can be aligned and fitted to close the bag opening, and a reinforcing jacket is compounded on the side sealing edge connecting the first bag surface and the second bag surface, and the reinforcing jacket extends from the bag opening to the bag bottom along the height direction of the side sealing edge, and the cross section of the reinforcing jacket is V-shaped, and the inner groove of the reinforcing jacket clamps the first bag surface and the second bag surface.
[0007] Preferably, the plastic support strip comprises a hollow protective shell and a metal wire hidden in the hollow protective shell.
[0008] Preferably, the hollow protective shell is a rubber shell, and the metal wire is an iron wire.
[0009] Preferably, a kraft paper pad is provided at the bottom of the bag, and the kraft paper pad extends along the bottom seal edge connecting the first bag surface and the second bag surface of the bag bottom, and the cross-section of the kraft paper pad is V-shaped, and the two sides of the kraft paper pad are respectively abutted against the first bag surface and the second bag surface.
[0010] Preferably, a hand-pull tab is clamped and connected between the first bag surface and the plastic support strip thereon, and a hand-pull tab is also clamped and connected between the second bag surface and the plastic support strip thereon.
[0011] Preferably, the surface of the hand-pull tab is light-transmissive, and the hand-pull tab is a bag-like structure with one side open.
[0012] Preferably, the reinforcement jacket is a kraft paper jacket.
[0013] The technical effects achieved by the technical solution of the utility model mainly include:
[0014] The plastic support strip extending along the edge of the bag opening on the corresponding surface can play the role of the bag opening support structure. After the user pulls open the bag openings of the first bag surface and the second bag surface, the bag opening is shaped and will not be closed again after the external force is removed. Before putting the item into the bag, the bag opening can be opened and shaped according to the structure of the item, so as to avoid the item directly stretching the bag opening and preventing the bag body from being directly squeezed due to improper placement.
[0015] The pearl cotton packaging bag can improve the structural strength of the side seal by further arranging a reinforcing jacket on the side seal to clamp the first bag surface and the second bag surface, thereby preventing the seals at both ends from cracking downward when the bag mouth is opened, thereby making up for the defects of the pearl cotton packaging bag in the prior art due to its simple and fragile structure and poor overall tensile performance and tear resistance.
