Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically to a compression-resistant packaging bag. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during the production and distribution process. They are widely used in daily life and industrial production.

[0003] Packaging bags are generally transported after packaging, but they are easily squeezed during transportation, which can damage the goods inside and affect product quality. Existing solutions often use thickened materials or external fillers, but these are costly and not environmentally friendly. At the same time, stress concentration when the bag surface is subjected to local pressure can easily cause it to break. Therefore, we propose a compression-resistant packaging bag.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a compression-resistant packaging bag.

[0026] Combination Figure 1-3 As shown, the present invention provides a compression-resistant packaging bag, comprising a bag body 1 and a sealing edge 2, wherein the bag body 1 is composed of, from the inside out:

[0027] Waterproof inner layer 11 is made of one of PE film, PET film or CPP film;

[0028] The three-dimensional support mesh layer 12 is composed of a grid skeleton formed by intersecting X-shaped elastic support columns 121;

[0029] The buffer layer 13 is filled with nano-aerogel particles;

[0030] The printing substrate layer 14 has a printed pattern area on its surface.

[0031] The above four layers of structure respectively undertake the functions of sealing, load-bearing, stress distribution, and appearance printing, and the design is reasonable.

[0032] Specifically, through the three-dimensional synergistic cooperation of the X-shaped elastic support column 121, the nano-aerogel-filled buffer layer 13, and the printed substrate layer 14, the internal pressure absorption and surface stress distribution functions are achieved, resulting in a 95% increase in pressure resistance and solving the problem of traditional packaging bags being easily deformed and broken under pressure.

[0033] Furthermore, the nano-aerogel particles have a particle size of 10-100nm and a filling rate of >95%. Through the ultra-fine particle size, they can penetrate into all the gaps in the elastic support column 121. This high filling design can form a continuous medium layer, and the external force transmission path is uninterrupted, resulting in lower surface undulation of the packaging bag when under pressure.

[0034] Furthermore, the printing substrate layer 14 is a biaxially oriented polyester film with a thickness of 0.05-0.2μm and a roughness Ra≤0.1μm. The low roughness allows the ink to spread more evenly, while the polyester material has solvent resistance and better adaptability to printing and processing.

[0035] On the other hand, the elastic support column 121 is made of thermoplastic polyurethane, which has good structural strength, thereby improving the packaging bag's resistance to compression.

[0036] Furthermore, an antistatic coating 15 with a surface resistance ≤10 is provided between the waterproof inner layer 11 and the three-dimensional support mesh layer 12. 8 Ω, the antistatic coating 15 can eliminate static electricity generated by friction and protect the electronic equipment inside. It is mainly used for packaging of electronic products, and can be omitted when it is used for food products.

[0037] Furthermore, the height of the elastic support columns 121 is 0.5-3mm, their arrangement direction is perpendicular to the bag body 1, they support outward force, and the mesh density is 20-50 columns / cm². 2 This ensures that pressure is distributed without any blind spots, resulting in better anti-compression effect.

[0038] In this application, the term "composite" in the context of functional thin film laminated systems specifically refers to molecular / interface-level bonding. Specific implementation methods include vapor deposition bonding, hot pressing bonding, solution coating-drying, plasma treatment coupling, co-extrusion casting, dip coating, and adhesive bonding. Such descriptions explicitly exclude mechanical connection methods such as welding, riveting, or screw fixing.

[0039] The above explanation of layered structures refers to the configuration relationship that can be understood and implemented by those skilled in the art based on the function of the relevant components, the context, and common knowledge. Its purpose is to clearly describe the relative positions, cooperation methods, and functional implementation paths between structures. To ensure smooth and concise reading of the manual and to facilitate understanding, no separate explanation is provided after the corresponding terms.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
