The maximum pressure a bubble bag can withstand depends on several factors, including its material, the size and density of the bubbles, the thickness of the bag, and the manufacturing process.
Generally speaking, the maximum pressure that a bubble bag made of common polyethylene can withstand varies. A thinner bubble bag with smaller bubbles and lower density may be able to withstand a pressure of several kilograms to more than ten kilograms. A thicker bubble bag with larger and denser bubbles may be able to withstand tens of kilograms or even more.
For example, a bubble bag used to package small electronic products usually only needs to withstand a small pressure, perhaps around 5-10 kilograms. This is because such products are lightweight and are relatively less impacted during transportation. However, if it is used to package large glass products or heavier mechanical equipment parts, the bubble bag may need to be able to withstand more than 30 kilograms of pressure to provide adequate protection.
The material of the bubble bag also has an important impact on its ability to withstand pressure. High-quality polyethylene materials usually have better toughness and strength and can withstand greater pressure. And some bubble bags with added reinforcing fibers or special coatings may further improve their pressure resistance.
In addition, the manufacturing process of the bubble bag will also affect its pressure-bearing performance. If the bubbles are well sealed and evenly distributed during the production process, and the overall structure of the bag is more stable, the pressure it can withstand will increase accordingly.
In order to accurately determine the maximum pressure that a bubble bag can withstand, professional testing is usually required in a laboratory environment. During the test, pressure testing equipment is used to gradually increase the pressure on the bubble bag until the bag breaks or is obviously damaged. The pressure applied at this time is its maximum pressure.
It should be noted that the pressure that the bubble bag withstands in actual use is not a fixed value, but is also affected by the external environment. For example, temperature changes, high temperatures may soften the material and reduce its pressure resistance; low temperatures may make it brittle and easy to break.
In actual applications, if the pressure resistance requirements for packaging are high, it cannot rely solely on the bubble bag. It may also be necessary to combine other stronger packaging materials, such as foam boards, wooden boxes, etc., to ensure that the items are fully protected during transportation and storage.
