Description

Technical Field

[0001] This utility model belongs to the field of corrugated paper technology, specifically relating to a puncture-resistant and anti-static corrugated paper packaging structure. Background Technology

[0002] Corrugated paper packaging has been widely used for product packaging and protection in many fields such as logistics and transportation, electronic components, precision instruments, and industrial parts due to its advantages such as low cost, light weight, strong recyclability, and good cushioning performance. It is one of the most widely used and largest-volume packaging forms in the current packaging industry.

[0003] Traditional corrugated cardboard packaging typically consists of a single or multiple layers of corrugated cardboard core laminated with kraft paper. Its structural strength relies primarily on the support of the corrugated cardboard core, while the kraft paper and corrugated cardboard core themselves have relatively weak puncture resistance. During logistics and transportation, the packaged goods are easily subjected to collisions or friction with sharp objects, which can easily lead to punctures and damage to the corrugated cardboard packaging. This can result in scratches, damage, or loss of the internal products (such as precision electronic components, glassware, and metal parts), causing economic losses to the company. Utility Model Content

[0004] The purpose of this utility model is to provide a puncture-proof and anti-static corrugated paper packaging structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a puncture-resistant and antistatic corrugated paper packaging structure, comprising a core support layer, a puncture-resistant and abrasion-resistant layer, and an antistatic layer. The core support layer comprises a corrugated paper core, an outer kraft paper layer bonded to the outside of the corrugated paper core, and an inner kraft paper layer bonded to the inside of the corrugated paper core. The corrugated paper core is filled with nano-aerogel particles. The puncture-resistant and abrasion-resistant layer is bonded to the outside of the outer kraft paper layer. The antistatic layer comprises an outer antistatic layer bonded to the inside of the inner kraft paper layer and an inner antistatic layer bonded to the inside of the outer antistatic layer.

[0006] In a preferred embodiment, the puncture-resistant and abrasion-resistant layer is an ultra-high molecular weight polyethylene fiber mesh.

[0007] In a preferred embodiment, a water-based composite adhesive layer is provided between the puncture-resistant and abrasion-resistant layer and the outer kraft paper layer, and the puncture-resistant and abrasion-resistant layer is bonded to the outer kraft paper layer through the water-based composite adhesive layer.

[0008] In a preferred embodiment, the antistatic outer layer is carbon fiber composite paper.

[0009] In a preferred embodiment, a water-based PU adhesive layer is provided between the antistatic outer layer and the kraft paper inner layer, and the puncture-resistant and abrasion-resistant layer is bonded to the kraft paper outer layer through the water-based PU adhesive layer.

[0010] In a preferred embodiment, the antistatic inner layer is an antistatic modified PP nonwoven fabric.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This puncture-resistant and antistatic corrugated paper packaging structure, through the setting of the core support layer, can bear the overall rigidity, compression resistance and cushioning capacity of the packaging, and disperse the puncture force transmitted by the outer layer. Through the setting of nano aerogel particles, it can improve the cushioning performance of the corrugated paper core. Through the setting of the puncture-resistant and wear-resistant layer, it can directly resist the puncture of sharp objects from the outside and prevent the packaging from being damaged. This puncture-resistant and antistatic corrugated cardboard packaging structure, through the setting of the antistatic layer, allows the outer antistatic layer to quickly discharge the static electricity accumulated inside the packaging, preventing electrostatic discharge from damaging the product, while the inner antistatic layer directly contacts the product, achieving close-fitting static protection and flexible cushioning to avoid scratches on the product surface.

Detailed Implementation

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-2This utility model provides a puncture-resistant and antistatic corrugated paper packaging structure, including a core support layer 1, a puncture-resistant and abrasion-resistant layer 2, and an antistatic layer 3. The core support layer 1 includes a corrugated paper core 11, a kraft paper outer layer 12 bonded to the outside of the corrugated paper core 11, and a kraft paper inner layer 13 bonded to the inside of the corrugated paper core 11. The core support layer 1 provides overall rigidity, compression resistance, and cushioning capacity for the packaging, while dispersing the puncture force transmitted from the outer layer. The corrugated paper core 11 is filled with nano-aerogel particles 14. The nano-aerogel particles 14 improve the cushioning performance of the corrugated paper core 11 and, to a certain extent, prevent the corrugated paper core 11 from collapsing under strong pressure.

[0017] The puncture-resistant and abrasion-resistant layer 2 is bonded to the outside of the kraft paper outer layer 12. A water-based composite adhesive layer 4 is provided between the puncture-resistant and abrasion-resistant layer 2 and the kraft paper outer layer 12. The puncture-resistant and abrasion-resistant layer 2 is made of ultra-high molecular weight polyethylene fiber mesh. Through the setting of the puncture-resistant and abrasion-resistant layer 2, it can directly resist the puncture of sharp objects from the outside and prevent the packaging from being damaged.

[0018] The antistatic layer 3 includes an antistatic outer layer 31 bonded to the inside of the kraft paper inner layer 13 and an antistatic inner layer 32 bonded to the inside of the antistatic outer layer 31. A water-based PU adhesive layer 5 is provided between the antistatic outer layer 31 and the kraft paper inner layer 13. The puncture-resistant and abrasion-resistant layer 2 is bonded to the kraft paper outer layer 12 through the water-based PU adhesive layer 5. The antistatic outer layer 31 is carbon fiber composite paper, which is made of carbon fiber and wood pulp plant fiber. The antistatic inner layer 32 is antistatic modified PP nonwoven fabric, which is made by adding antistatic agents to PP nonwoven fabric. Through the setting of the antistatic layer 3, the antistatic outer layer 31 can quickly discharge the static electricity accumulated inside the packaging to prevent electrostatic discharge from damaging the product. The antistatic inner layer 32 is in direct contact with the product, achieving close-fitting static protection and flexible cushioning to avoid scratches on the product surface.

[0019] The working principle and usage process of this utility model are as follows: First, the core support layer 1 can bear the overall rigidity, compression resistance and cushioning capacity of the packaging, and disperse the puncture force transmitted by the outer layer. The nano aerogel particles 14 can improve the cushioning performance of the corrugated paper core 11. The puncture-resistant and wear-resistant layer 2 can directly resist the puncture of sharp objects from the outside and prevent the packaging from being damaged. The antistatic layer 31 can quickly discharge the static electricity accumulated inside the packaging to prevent electrostatic discharge from damaging the product. The antistatic inner layer 32 directly contacts the product, achieving close-fitting electrostatic protection and flexible cushioning to avoid scratches on the product surface.
