Bubble wrap usually consists of two layers of film with many small bubbles formed between the two layers of film. These bubbles can reduce the impact of external shocks and vibrations on items and act as a buffer. When an item is squeezed or impacted, the bubbles in the bubble wrap will deform and absorb energy, reducing the direct impact of external force on the item.

In addition to being used as packaging materials, bubble wrap can also be used for other purposes, such as insulation materials, bottom materials, shock-proof pads, etc. In construction and decoration, bubble paper can be used for heat and sound insulation to reduce the conduction of heat and noise. In some special cases, bubble wrap can also be used as a waterproof material.

In general, bubble paper is a common and practical packaging and protective material with good buffering and protective effects. It plays an important role in protecting fragile items during transportation, mailing and packaging, and also has other application areas.

Bubble wrap has many advantages, such as being lightweight, soft, durable, heat-insulating, moisture-proof, etc. It is widely used in packaging and protection in various fields, especially during the transportation and mailing of fragile items such as electronic products, glass products, ceramics, furniture, artworks, and mail packages.
