52 results about "Antistatic bag" patented technology

An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film, pink or black for polyethylene). The polyethylene variant may also take the form of foam or bubble wrap, either as sheets or bags. Multiple layers of protection are often used to protect from both mechanical damage and electrostatic damage. A protected device can be packaged inside a metalized PET film bag, inside a pink polyethylene bubble-wrap bag, which is finally packed inside a rigid black polyethylene box lined with pink poly foam. It is important that the bags only be opened at static-free workstations.

Anti-static polyethylene film material and preparation method thereof, as well as anti-static bag

The invention discloses an anti-static polyethylene film material and a preparation method thereof, as well as an anti-static bag. The anti-static polyethylene film material is prepared from the following raw materials in percentage by weight: 60-70 percent of linear low-density polyethylene, 20-30 percent of high-pressure polyethylene, 2-5 percent of low-pressure polyethylene and 3-5 percent of anti-static masterbatches. The preparation method of the anti-static polyethylene film material comprises the following steps: respectively weighing all the components in part by weight; putting all the components in an extruder for extrusion, wherein the temperature of a first zone of the extruder is 145-155 DEG C, the temperature of a second zone is 150-160 DEG C, the temperature of a third zoneis 150-160 DEG C, the temperature of a die head of the extruder is 150-170 DEG C, the rotating speed of a lead screw is 100-120 r/min, and the host frequency is 12-14 HZ; after extrusion, cooling, forming and winding to obtain the anti-static polyethylene film material. As the anti-static masterbatches and the low-pressure polyethylene are added, the anti-static polyethylene film material disclosed by the invention not only has a very good anti-static effect, but also is good in opening performance.

An anti-static film double-sided hot-melt welding edge sealing bag forming machine

ActiveCN111267364BImprove the efficiency of automatic edge bandingDomestic articlesAntistatic bagHot melt
The invention discloses an antistatic film double-sided hot-melt welding edge-sealing bag forming machine, which includes a frame with a conveying roller, an automatic clamping and folding component, a distance-adjustable pulling component, a hot-melt welding component, and an automatic cutting Assemblies and output boxes, the automatic clamping and turning components include a transmission box on one side, two turning rollers, a turning lever and an automatic clamping component fixed at the front end of the turning lever. The bracket and the outer ring of the heat-welding roller are equipped with a heat-welding roller, which is connected to an electric heating device. It adopts the method of symmetrical folding and synchronous pulling and heat-bonding to realize automatic edge sealing into bags, and the single-layer anti-static material fed flat After the film is clamped and reversely folded 180 degrees, the upper and lower layers of the anti-static film are hot-melt bonded to the edges to be sealed on both sides of the anti-static film through the hot-melt welding component, and at the same time, the gradually formed part The anti-static bag is pulled forward to the forming position, and then the anti-static film is cut horizontally by the cutting knife, and then the material is unloaded, which can realize continuous heat bonding and edge sealing to form a bag.

Dust-free PE antistatic bag

The invention discloses a dust-free PE antistatic bag which comprises a bag body, a clamping block and a clamping groove. When a connecting module is installed, four insertion rods and tip ends on a first connecting block on the bag body penetrate openings in a second connecting block for tight cooperation so that the first connecting block and the second connecting block can be connected together, the connecting module is then successfully installed on the bag body, and the bag body is better not likely to be damaged; and two connecting protruding blocks which are arranged in parallel are arranged on the clamping block, fixing inclined blocks are arranged on the lower sides of the connecting protruding blocks; connecting grooves which are formed in parallel are formed in the back face ofthe clamping block, fixing grooves are formed in the bottom sides of the interiors of the connecting grooves, due to cooperation of the connecting protruding blocks and the connecting grooves and cooperation of the fixing inclined blocks and the fixing grooves, two connecting modules can be connected, and connection between multiple bag bodies can be successfully achieved. When too many bag bodiesexist and one hand cannot pinch all the bag bodies, a connecting line can be used for penetrating connecting rings, then the multiple connecting modules are connected, carrying is more convenient, and operation is convenient and fast during use.
