Information
1: "Vacuum Bag"
 
One of the vacuum packaging forms. In the vacuum packaging method, the vacuum packaging method is confidential. The product is packaged into a confidential packaging container. The air-tight container inside the container forms the fourth line due to the air-tight container. Vacuum bag and decompression bag, all air-sealed containers, continue the state of high-pressure air bag, due to the lack of relatively low oxygen, this is the living environment of microorganisms.
 
2: The scope of the vacuum bag
 
At present, it is mainly vacuum packaged food processed food. For example, meat, meat, processed food, easily oxidized food, mechanical parts, electronic parts, documents, badminton products, wool products and other fluffy product packaging.
 
3: Vacuum bag effect
 
Vacuum bags can reduce the volume of such containers. Universe water-water transportation and storage costs. After it has good strength and resistance to explosions, the product package is not easily broken. It can effectively prevent the weight that can be effectively packaged, broken traffic, and easy to be hit. Good, good high temperature and high temperature around 11:50 Even if it is low temperature, it is not easy to age, that low complete oxygen, blockage, anti-virus, oil, Good performance and high quality, can improve the quality of the vacuum bag products.

More information

Due to the moisture absorption of nylon film and the series of adverse consequences caused by moisture absorption, there are certain requirements for the environment of paper-plastic packaging manufacturers. Generally, it should be stored at about 23°C, ±3°C, and the dry humidity difference is ideal within the range of 60%RH±5%RH. The nylon membrane cannot be placed directly on the floor or in the open air to avoid moisture absorption. The difference between dry and wet in the production environment generally does not exceed 75% RH. If it reaches 80% RH, production should be stopped (especially compound production) to avoid bad causes. If the task must be put into production, exhaust fans and dehumidifiers can be added to the production site to enhance indoor air circulation and reduce the humidity of the production environment to below 70%RH for reproduction. In short, when the humidity exceeds 70%RH, you must use it with caution. When the temperature is low or the humidity is too high, you must turn on the preheating equipment of the printing and laminating machine, first preheat the nylon film, and dry it on the surface of the nylon film. In order to facilitate the smooth progress of printing and composite production; at the turn of winter and spring, due to large temperature changes, when using mixed solvents, pay attention to effective adjustments with changes in temperature to prevent solvents from evaporating too fast or residual solvents. More quality accidents.
In addition to containing and sealing the product, a packaging bag is more important to isolate the product from the outside world to protect the product. In addition, the molecular interaction between the packaging material itself and the product causes the product to deteriorate, which has become a problem that the packaging bag manufacturer needs to solve. This article focuses on explaining how we solved this problem. Packaging bag manufacturers generally use PE material film in direct contact with the product. So, what is a PE material film?
Plastic packaging bag manufacturers tell us that we need to pay more attention to the later stage of manufacturing products, because the product will over-harden if you are not careful. This phenomenon occurs because the proportion of ingredients has not been properly handled. Today we will understand how to prevent it. The appearance of hardening.
Will the vacuum food packaging bag wrinkle? How to solve it? 1. Replace the qualified film. 2. Adjust the position of the film so that it does not deflect during the conveying process. 3. Adjust the amount of glue applied and apply glue evenly. 4. Adjust the process parameters to make the adhesive fully dry and reduce the residual amount of solvent. 5. The composite film should be fully cooled before rewinding. 6. Adjust compound pressure. 7. Adjust the tension of unwinding and rewinding to match the tension of each part. 8. Adjust the parallelism of each guide roller. 9. Clean the surface of each guide roller and replace the damaged guide roller to ensure that the surface of the guide roller is flat, smooth and clean.
Among the applied materials of plastic packaging bags, there are often three-layer, five-layer, seven-layer, and nine-layer composite films. What is the difference between different layers of composite film? 5 layer and 3 layer comparison
