The emergence of more and more shopping supermarkets requires the packaging of goods not only to meet the safety of the packaging products’ hygiene, transportation, and storage. This is a basic requirement. At the same time, it is a basic requirement for packaging products, especially outer packaging products, to pass display shelves. Ease of display, brand emphasis, etc. all put forward higher requirements for commercial aesthetics. Therefore, the different manufacturing technologies and design principles of various packaging machines provide users with diversified choices.
If the packaging type of the pouch packaging is classified according to the appearance, it can be roughly divided into the following three main categories: three-side sealing, four-side sealing, and back sealing (or called pillow bag). Of course, on this basis, there are very rich varieties of deformation.
Elin Packaging Machinery Co.,Ltd, as a manufacturer of Small Bag Packer, has always focused on the manufacture and design of vertical pouch packaging machinery.
The Powder Packing Machine, especially the vertical Powder Packing Machine, may cause the bag opening to be not tightly closed or affect the appearance during the packaging. As for how to solve the powder clamping, we must first find out the cause of the powder clamping. Reasons in order to solve them in a targeted manner.
Based on on-site experience, we summarize the causes and solutions of several failures causing powder clamping:
1. The timing of horizontal sealing is too high.
Solution: Adjust the horizontal sealing time
2. The blanking device is not tightly closed, and there is material leakage.
Solution: Mainly spiral feeding method, adding leak-proof device
3. The bag maker electrostatically adsorbs materials.
Solution: Find a way to eliminate the static electricity of the packaging material, or add an ion wind device.

The leakage of alkaline battery has a very important relationship with the structure of the battery. Because the cathode active material is zinc powder, it greatly increases the real surface area of the cathode and increases the battery capacity. But at the same time, it is prone to corrosion. There is a lot of gas generated inside the battery. When the internal pressure is too high, the strong pressure may deform the parts at the seal and cause the battery to leak.
In order to prevent the leakage of alkaline battery, alkaline battery manufacturers usually take the following measures in the production:
1. Apply sealing glue. Since the contact surfaces of the seals are not all really flat and there are many capillary channels, sealing glue must be applied between the steel cylinder and the sealing ring and the center of the sealing ring to block the capillary channels.
2. Improve the sealing structure and sealing process. Since the outer diameter of the upper part of the sealing ring is tightly fitted with the inner diameter of the flaring part of the steel cylinder, the outer diameter of the lower part of the sealing ring is a loose fit with the inner diameter of the steel cylinder. Therefore, only by axially and radially compressing the upper part of the sealing ring can the sealing purpose be achieved.
3. Improve the sealing ring. The material and structure of the sealing ring are also the main measures to improve the sealing effect. After comparing several common sealing processes and the principle of the sealing machine, it is found that the key to the sealing process is the deformation of the steel shell and the elastic compression of the sealing ring. The compression effect is achieved in the transverse direction, and the purpose of sealing can be achieved.
Prevent the leakage of alkaline battery and do a good job of quality control, so that alkaline battery can always make breakthroughs and walk in the forefront of the battery industry.
What are the storage methods of high temperature tape:
1. The high-temperature tape should be stored in the warehouse to avoid sunlight and rain; it is forbidden to contact with acid-base oil and organic solvents, keep it clean and dry, 1m away from the discovery device, and the room temperature is between -15°C and 40°C.
2. The high temperature tape should be placed in a roll without folding. When the storage time is too long, it needs to be turned once every season.
3. When loading and unloading the conveyor belt, use a crane, and the rigging with a beam should be hoisted smoothly to avoid damage to the belt edge.
4. The type and specifications of the high temperature tape should be selected reasonably according to the use needs and specific conditions.
5. It is not allowed to connect (group) tapes of different varieties, specifications, models, strengths, and layers of cloth together.
6. Conveyor belt joints adopt thermal vulcanization bonding to improve reliability and maintain high effective strength.
7. The diameter of the conveyor roller of the conveyor and the diameter of the small pulley of the conveyor belt should meet the relevant regulations.
8. Don't let the tape snake or creep, keep the drag roller, the vertical roller flexible, and the tension should be moderate.
9. When the conveyor is equipped with baffles and cleaning devices, the abrasion of the tape should be avoided.
10. Cleanliness is the basic condition for the good operation of the tape. Foreign matter will affect the eccentricity of the tape, the difference in tension, and even breakage.
11. If you find that the high temperature tape has early damage during use, you should find the cause in time and repair it to avoid adverse consequences.
There are many types of tape, and among the many types of tape, everyone chooses to use scotch duct tape for sealing and packaging. Then, why choose scotch duct tape?
1. The protection of transparent tape.
Protection provides the surface protection of the product, forming a very light and protective appearance at the sealing of the product package, so as to achieve the purpose of dustproof, oilproof, moistureproof, waterproof and anti-theft. The most important thing is that the scotch tape makes the packaged items evenly stressed, so as to avoid damage to the items due to uneven force.
2. The fixability of the transparent tape.
The scotch duct tape is sufficiently sticky and has good fixability. When the scotch tape is used to seal the carton, it is not easy to break the carton seal, and the carton is less likely to be deformed when it is squeezed.
3. The economy of scotch duct tape.
scotch duct tape has the advantage of low price compared to other types of tape. Using scotch tape for carton packaging can effectively reduce the cost of use. This should be the most important factor in choosing scotch tape for sealing and packaging.
