Detailed Description

Example 1

Referring to fig. 1, an impact-resistant printing ink bag, comprises a bag body, the bag body is tailor the hot pressing by two complex films and forms, the complex film outside-in is wear-resisting extexine 1, intensity layer 2, light shield layer 3, intensity layer 2 and stress-resistant substrate layer 4 in proper order, bonds through anticorrosive glue film 5 between each layer.

The wear-resistant outer surface layer 1 is a film layer made of polyethylene terephthalate, the thickness of the film layer is 12 microns, the polyethylene terephthalate is a polar material and can prevent oxygen from entering, the wear resistance is good, the wear-resistant outer surface layer also has the characteristic of being not prone to generating wrinkles, and the attractiveness of the embodiment is guaranteed.

In this embodiment, the two strength layers 2 are respectively disposed on two sides of the light shielding layer 3, which takes into account that if only one strength layer 2 is disposed, the ideal impact resistance and tear resistance cannot be achieved; on the other hand, if the thickness of the strength layer 2 is simply increased, stress is easily concentrated when the strength layer is subjected to external impact, but the impact resistance and the tearing resistance of the strength layer are reduced, and the composite film is easy to crack when being hot-pressed due to the excessively thick film layer, so that the quality of the finished product of the composite film is influenced; in the composite film, the impact may be from the outside to the inside or from the inside to the outside during the production process, and therefore, the strength layers 2 disposed on both sides of the light-shielding layer 3 can better cope with the impact from different directions.

The strength layer 2 is a film layer made of polyamide, the thickness of each strength layer 2 is 15 μm, the polyamide has excellent tensile strength and tear resistance, and the polyamide is a high-strength polar material, so that the present embodiment has good organic solvent resistance, acid and alkali resistance and water vapor barrier properties.

The shading layer 3 is a film layer made of metal foil materials such as aluminum foil and the like, has the thickness of 7 mu m, mainly has the function of isolating light and certain water-proof performance, and prevents ink from being denatured.

The stress-resistant base material layer 4 is a film layer prepared by mixing any one or more of low-density high-pressure polyethylene (LDPE), linear low-density polyethylene (LLDPE) and metallocene linear low-density polyethylene (mLLDPE), and the thickness of the film layer is 91 mu m. Polyethylene is chosen because it has good processability and heat sealability, facilitates film formation and hot pressing, and has good chemical stability, and is neither attacked by inks with complex compositions nor affects the properties of the inks. The reason why metallocene linear low density polyethylene (mLLDPE) was selected as the preparation raw material in this example is that: compared with other polyethylene raw materials, the mLLDPE has better stress cracking resistance, and can assist in enhancing the impact resistance and the tearing resistance of the embodiment.

Considering that the present embodiment is applied to packaging ink with complicated components, the anti-corrosion adhesive layer 5 is a polyurethane adhesive, and has the characteristics of solvent resistance, strong adhesion to the above materials of each layer, and good adhesion effect.

Referring to fig. 2, in this embodiment, the bag body is rectangular, and includes a cavity area 6 and an edge hot-pressing area 7 surrounding the cavity area 6, and the bag body is provided with a tearing notch 9, which is convenient to open.

The turning parts of the edge hot pressing area 7 are all in arc transition, so that a sharp-angled structure which can cause ink residue is avoided, and the utilization rate of the ink is improved.

The finished product of complex film is thin and stiff, consequently, the corner of the bag body is the fillet, prevents that the finished product from scraping each other in transportation pile up process, and on the other hand is in order to avoid fish tail hand.

Example 2

Referring to fig. 3, the present embodiment is different from embodiment 1 in that: the edge of the cavity containing area 6 is provided with an opening area 8 which extends outwards and protrudes, the cavity containing area 6 is connected with the opening area 8 through a gradually reduced smooth transition section, the gradually reduced design is to avoid ink from easily pouring out when unsealing, and the smooth transition design is to reduce ink residue.

In this embodiment, the two sides of the opening area are provided with tearing notches 9, which is convenient for users to tear from any direction.

The other structure of this embodiment is the same as embodiment 1.

Examples 1 and 2 were tested according to the method of the thermoplastic flexible film bag part 2 of the national standard GB/T25162.2-2010 bag drop test, and the test results demonstrate that: examples 1 and 2, which have been loaded with ink, can be dropped from a height of up to 1.6 meters without breakage or deformation, and have superior impact resistance and tear resistance.

The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
