The application discloses an environment-friendly anti-static bubble bag and belongs to the technical field of bubble bags. The bubble bag comprises an upper bag body, a lower bag body and a bag sealing assembly which are matched with each other. The upper bag body and the lower bag body are both made of degradable materials. Bubble film layers are compounded on the outer walls of the upper bag body and the lower bag body. Anti-static coating layers are arranged on the outer surfaces of the upper bag body and the lower bag body. The bag sealing assembly is detachably connected to the butt joint positions of the upper bag body and the lower bag body. The upper bag body and the lower bag body are detachably separated through the detachable bag sealing assembly. The upper bag body and the lower bag body are made of degradable materials. The outer walls of the upper bag body and the lower bag body are compounded with bubble film layers, so that the cushioning and protection performance is considered. The bag body can be disassembled when the articles are taken out through the detachable design of the bag sealing assembly, so that the inner wall of the bubble bag without the anti-static coating layer is fully exposed. The degradable base material can be greatly accelerated in the degradation rate. The packaging protection practicability, the anti-static safety and the whole-cycle environment-friendly adaptability are considered.

According to the scheme provided by the invention, air discharge can be carried out on the periphery of the LCD screen, so that the electrostatic discharge capability of the LCD is improved.

The invention provides a multi-chip packaging structure and a packaging method, and relates to the field of packaging. The multi-chip packaging structure comprises a first chip, a second chip and a substrate, the second chip is a flip chip; each of the first chip and the second chip comprises a first surface and a second surface which are opposite to each other, and the first surfaces are the surfaces where the salient points are located; part of the salient points on the first surface of the second chip are welded with the salient points on the first surface of the first chip; other salient points on the first surface of the second chip are also connected with a bonding pad on the surface of the substrate; the second surface of the first chip is electrically connected with the substrate. The multi-chip packaging structure can effectively improve the electrical performance and reduce the size.

This invention discloses an environmentally friendly antistatic bubble bag, belonging to the field of bubble bag technology. It includes an upper bag body, a lower bag body, and a sealing assembly that cooperate with each other. Both the upper and lower bag bodies are made of biodegradable materials, and both have a bubble film layer laminated to their outer walls. Both the upper and lower bag bodies also have an antistatic coating on their outer surfaces. The sealing assembly is detachably connected to the joint between the upper and lower bag bodies, allowing for easy separation. The combination of biodegradable materials for the upper and lower bag bodies, the bubble film layer on the outer wall providing cushioning and protection, and the detachable design of the sealing assembly allows the bag to be disassembled when the contents are removed, fully exposing the inner wall of the bubble bag without the antistatic coating. This significantly accelerates the degradation rate of the biodegradable substrate, balancing practicality, antistatic safety, and lifecycle environmental adaptability.

This invention discloses an antistatic blended cotton yarn and its preparation method, belonging to the technical field of blended cotton yarn. The antistatic blended cotton yarn comprises the following raw materials in parts by weight: 60-80 parts of antistatic modified cotton fiber, 10-25 parts of regenerated cellulose fiber, and 3-10 parts of antistatic polyester staple fiber. The antistatic blended cotton yarn prepared by this invention exhibits good antistatic, antibacterial, anti-aging, and wash-resistant stability.

The present invention relates to an LCD display screen of a plasma fan, comprising a display screen body, a display pattern is arranged on the display screen body, a group of basic pin positions are arranged at the lower part of the display screen body; a first discharge line is arranged at the upper end and left and right edges of the display screen body, and a group of outward edge discharge tips are arranged on the discharge line; a grounding pin position is added on the left and right sides of the basic pin position, and the two grounding pin positions are respectively provided with a second discharge line connected to the first discharge line, and a group of outward edge discharge tips are arranged on the second discharge line. The present invention can effectively solve the problem that the existing LCD display screen of the plasma fan only has the first discharge line with a discharge tip arranged at the upper end and left and right edges of the display screen body, the discharge effect is very poor, the anti-static effect is equivalent to no effect, PI breakdown is easy to occur, black and white dots are formed, the screen reality effect is like light leakage, and it becomes a waste product, which affects the yield of the product.
