Description

Four-edge sealed packaging bag for hygienic products

Technical Field

The utility model relates to a wrapping bag technical field especially relates to a four sides seal health supplies wrapping bag.

Background

Among the used material of traditional wrapping bag membrane, there are PE material and CPP material, wherein CPP membrane material is too hard, can cause the damage to the soft articles for use of inlayer, consequently is not suitable for health supplies's packing material, and when CPP rete was made alone, its single membrane preparation thickness was about 5.5 ~ 6 silks, because the single membrane of independent manufacturing can't further compress thickness, consequently its manufacturing cost receives the restriction.

If the PE film is used as a package of sanitary products, the outer layer film is required to have the function of light absorption and scattering in order to ensure the packaging life of the sanitary products, so the extinction PE film material is required to be used, and the extinction PE film is required to be made of extinction particles. However, in China, the currently manufactured extinction particle products have crystal points, and the crystal points affect the printing effect (the printing color cannot be printed, and white spots appear at the crystal points). Therefore, the raw material of the sanitary product packaging film at present is under long-term technical monopoly by foreign companies.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the preferred embodiment of the present invention provides a four-side-sealed package bag for hygienic articles, which comprises a hollow bag body 1 formed by a composite film, wherein the four sides of the bag body 1 are sealed by hot melting to form a sealing knife 4 at the corner position, and the composite film comprises an outer CPP film 5 and an inner PE film 6.

The utility model discloses a complex film structure of outer CPP membrane and inlayer PE membrane preparation, inlayer PE membrane provide flexibility, feel, be difficult for leading to the fact the fish tail to inlayer health supplies, and outer CPP membrane provides structural rigidity and printability (PE chromatography is difficult, and CPP rigidity does not have tensile well, consequently is suitable for the colour to be colorful, the printing that the chromatography requires height). The utility model discloses a complex film has CPP and PE good characteristics between them concurrently, and it melts the limit performance, seals the performance and feels the feeling the same with pure PE's feeling (same thickness is gentler than the outer very inlayer of pure PE), possesses rigidity, printability and the characteristic of feeling simultaneously.

Under the same performance, pure PE does not thin (pure PE accomplishes that 5 silks are difficult, generally is 5.5 ~ 6 silks), the utility model discloses a thin degree (accessible equipment complex is made, if solvent-free compounding machine) that single membrane can't reach can be accomplished to the complex film, compares in prior art, and the cost can reduce 20%, is a novel complex film that breaks through foreign technology monopoly. The conventional PE film packaging bag does not have an outer CPP film, four edges of a display surface of the conventional PE film packaging bag are round corners and are too soft, and the display performance is poor; the utility model discloses a wrapping bag four sides are equipped with a sword, make its finished product third dimension better, have arris cornered, have good exhibition nature.

In this example, the minimum thickness of the composite film is 5 filaments. Wherein: the outer-layer CPP film 5 is an extinction CPP film and is prepared from CPP extinction master batches, so that the phenomenon of crystal points does not exist, and the printing effect can be met; the thickness of the outer CPP film 5 is 1.5-2.5 threads, preferably 2 threads. The 2-filament PE cannot be printed, so that the surface printability is ensured by using the 2-filament CPP, the color overprinting requirement is high, the color is more, the overprinting precision is high, and the minimum printing thickness of the PE film printing process can only be 3 filaments, so that the printing process can be thinner. The inner layer PE film 5 is a milky white PE film, the effect of subsequent printing is guaranteed, the thickness is 2.5-4 threads, 3 threads are preferred, and the inner layer PE film has the effect of packaging and protecting the sanitary products by the flexibility of the PE film.

In this embodiment, the outer CPP film 5 and the inner PE film 6 are bonded by coating an adhesive, which may be a polyurethane adhesive; the contact surfaces of the outer CPP film 4 and the inner PE film 5 can also be welded, for example, the CPP film can be prepared by adopting a delustering CPP and polyethylene composite edge melting device which is published by the company CN215620077U, so that a high-performance composite material film with high stiffness, high temperature resistance, low temperature resistance and corrosion resistance is obtained, and then the packaging bag is prepared according to the conventional packaging bag processing method.

In this embodiment, the sealing tongue 2 is formed on the top of the bag body 1, and is generally sealed by hot melting. A sealing strip 7 is arranged between the sealing tongue 2 and the bag body 1, as shown in fig. 4, the sealing strip 7 comprises a clamping strip 9 and a meshing strip 10, and a groove 11 matched with the meshing strip 10 in shape is arranged in the middle of the clamping strip 9. The sealing strip 7 can be completely engaged between the clamping strip 9 and the engaging strip 10 when the bag body 1 is closed, so that the bag body 1 is completely closed. Specifically, the side wall of the sealing tongue 2 is further provided with a tearing opening 3, preferably, the tearing opening 3 is in a triangular structure, and the sealing tongue 2 can be directly torn through the tearing opening 3; still be equipped with easily tearing line 8 on the sealed tongue 2, tear mouthful 3 and be located the one end of easily tearing line 8, through tearing mouthful 3 and easily tearing line 8 cooperation, it is more laborsaving when tearing the wrapping bag.

The utility model discloses a wrapping bag design is simple, rational in infrastructure, convenient processing, and is safe durable, and is sealed effectual. The structure of the sealing strip can be completely engaged, so that the bag body is completely sealed, and the cleanliness of the sanitary articles in the packaging bag is ensured; through tearing the mouth and easily tearing the line cooperation, it is more laborsaving when tearing the wrapping bag.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
