A vacuum adsorption type cold-setting corrugated cardboard

Abstract

This application relates to the field of corrugated cardboard and discloses a vacuum adsorption type cold-setting corrugated cardboard. In this application, a fixing protrusion is fixedly installed on the lower surface of the cardboard body at a location that matches the limiting and fixing groove. The upper surface of the cardboard body is provided with a purification material layer and a moisture-proof material layer. A functional permeable membrane is adhered to the upper surface of the purification material layer and the adhesive edge strip. During the stacking and transportation of the cardboard body, the fixing protrusion on the lower surface of the cardboard body is aligned with the limiting and fixing groove on the upper surface of the cardboard body, and then the cardboard body is placed. At this time, the limiting and fixing groove and the fixing protrusion will form a locking fixation, preventing it from easily tipping over during transportation, thereby improving the overall stability and firmness during transportation. Simultaneously, the purification material layer and adhesive edge strip inside the cardboard body allow for the purification and absorption of odors inside the cardboard through the functional permeable membrane, thereby increasing the protective function of the cardboard body.

Description

Technical Field

[0001] This application belongs to the field of corrugated cardboard technology, specifically a vacuum adsorption type cold-setting corrugated cardboard. Background Technology

[0002] Corrugated cardboard is an environmentally friendly packaging material made of multiple layers of corrugated cardboard bonded together. It is lightweight, strong, and offers excellent compression resistance and cushioning. Its structure typically consists of one or more sheets of corrugated core paper (corrugated paper) and two or more sheets of flat paper (linerboard), bonded together with adhesives. The corrugated design of corrugated cardboard effectively improves its structural strength, reduces material usage, and lowers costs. Depending on the flute size, it is available in A, B, C, and E types, with type A being the largest and type E the smallest. Widely used in the packaging industry, especially in transport packaging, corrugated boxes, with their excellent protective performance and recyclability, have become an important protective carrier for goods during transportation.

[0003] For example, application CN216069067U discloses a multifunctional corrugated cardboard with antistatic, antibacterial, waterproof, and moisture-proof properties. The cardboard body includes a corrugated cardboard base layer, an inner functional layer, and an outer functional layer. The inner functional layer includes a bamboo fiber layer and an activated carbon filter paper layer. The outer functional layer includes a polycarbonate coating, an OPP film, and a waterproof and breathable membrane. This invention features an inner functional layer comprising a bamboo fiber layer and an activated carbon filter paper layer, and an outer functional layer comprising a polycarbonate coating, an OPP film, and a waterproof and breathable membrane. When exposed to water, the polycarbonate coating forms a droplet-like structure similar to water droplets on a lotus leaf, causing the water to slide off without penetrating the interior of the corrugated cardboard body. The compressive strength is not significantly reduced before the water evaporates, effectively protecting the entire structure. This solves the problem that existing corrugated cardboard has limited functionality, reducing its practicality and making it inconvenient for users.

[0004] However, during transportation and use, the cardboard in this application experiences instability and shaking between the upper and lower sections, resulting in poor transportation stability. Utility Model Content

[0020] By adopting the above technical solution, the overall anti-slip stability of the cardboard body is increased.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0022] In this application, during the stacking and transportation of the cardboard body, the fixing protrusion on the lower surface of the cardboard body is aligned with the limiting fixing groove on the upper surface of the cardboard body before placement.
