Here are some ways to reduce the thickness of the bubble envelope without affecting its performance:

Optimized bubble structure

Change the shape of the bubble: the traditional round bubble can be considered to be changed to oval, polygon and other special shapes. For example, the oval bubble in the same amount of material, can provide a larger buffer area, in the impact of external force, the long axis of the oval can better disperse the impact force, thereby reducing the thickness of the bubble film to a certain extent.

Adjust the bubble arrangement: Use a more scientific bubble arrangement, such as honeycomb arrangement. This arrangement can make the mutual support between the bubbles more stable, improve the overall compression performance, compared with the traditional random arrangement, while ensuring the buffer performance, the thickness of the bubble film can be appropriately reduced.

Improved material formulation

Add enhancer: Add an appropriate amount of enhancer, such as nano-sized calcium carbonate, silica, etc., to the raw material of the bubble film. These reinforcing agents can improve the mechanical properties of plastics, so that the bubble film still has good compressive and tensile resistance in the case of thin. For example, after the addition of nano-calcium carbonate, the hardness and toughness of the bubble film are improved, and it can withstand greater pressure without breaking.

Use high-performance plastics: Choose new plastic materials with higher strength and better toughness. For example, metallocene polyethylene (mPE) is used instead of traditional polyethylene (PE). Metallocene polyethylene has a narrower molecular weight distribution and better molecular chain regularity, and the bubble film made by it has stronger puncture resistance and tear resistance at the same thickness, so that the thickness can be reduced on the basis of ensuring protective performance.

Adopt multi-layer composite structure

Design functional gradient materials: the bubble film is designed into a multi-layer structure, and different layers use materials with different properties to form functional gradients. For example, the outer layer uses a material with high strength and good wear resistance, and the inner layer uses a material with soft and good cushioning properties. This can ensure the overall performance at the same time, by reasonable collocation of materials to reduce the overall thickness.

Add buffer layer: Add a thin buffer layer between the bubble film and the outer packaging material, such as foam sheet, elastic fiber layer, etc. These buffer layers can further improve the cushioning performance of the envelope without increasing the thickness of the bubble film, and effectively absorb and disperse the impact force.

It should be noted that when using the above method to reduce the thickness, it is necessary to verify whether the performance of the express bubble envelope meets the requirements through strict experiments and tests to ensure that it can effectively protect the express items in actual use.
