The cushioning effect of the Bubble bag mainly relies on its unique design and material. First, we need to understand the basic structure of Bubble bag. Bubble bags are composed of two layers of plastic film sandwiched by one or more layers of bubble wrap. These bubble wraps are filled with air, forming independent small bubbles.
These small bubbles play a key cushioning role in the Bubble bag. When the Bubble bag receives an external impact, the impact force will first act on the surface of the Bubble bag and then be transmitted to the bubbles inside. Because the bubbles are filled with air, they are very elastic and compressible. When impacted, the bubbles will quickly deform and absorb the impact energy, thereby reducing the impact force on the packaged items.
At the same time, the material of the bubble bag also has an important impact on its cushioning effect. Bubble bags are usually made of polyethylene (PE) material, which has excellent elasticity and toughness and can withstand a certain degree of tension and compression. When the bubble bag is impacted, the PE material can quickly recover its original shape, thereby maintaining the integrity of the bubble and the cushioning effect.
In addition, the design of the Bubble bag also takes into account the need for cushioning effect. The bubbles in the bubble bag are usually evenly distributed, which ensures that when impacted, the impact force can be evenly distributed to each bubble, thus improving the overall cushioning effect. At the same time, the sealing performance of the bubble bag is also very important. It can ensure that the air in the bubble will not leak, thereby maintaining the buffering capacity of the bubble.
In general, the cushioning effect of the Bubble bag is achieved through its unique design and material. When subjected to external impact, the bubbles in the bubble bag can quickly deform and absorb the impact energy. At the same time, the elasticity and toughness of the PE material can also maintain the integrity and cushioning effect of the bubbles. This cushioning effect can effectively reduce the impact on the packaged items, thereby protecting the items from damage during transportation and storage.
