气泡布（英文：Bubble Wrap）是一种塑胶包装材料，一般呈透明状，上面布满注入空气的小气泡，又称为气泡纸、泡泡纸。由于气泡能有效缓冲，避免包裹碰撞，因此通常用来包扎易碎物品。

气泡布最初是由美国的Airproduct公司发明的，他们是从幼童用的塑胶游泳池中得到概念的。现在的气泡布一般是由两块PE塑胶组成的，方法是在其中一面塑胶成型后突出的圆柱状中央注入空气后，再用另一块封闭，这样就能达到防压的用途。

一般用户会利用有气泡突起的一面来包裹物品，但实际上无论用任何一面的效果都是相同的。 而对于藏品(博物馆/美术馆收藏品)包装，如要单以气泡布包裹，应以「塑胶面」接触藏品，「气泡」朝外，是为避免气泡于长时间包装或外在环境因素导致塑胶材老化而在藏品上留有气泡的形状，较敏感的藏品材质如相片反应更甚。但如果需要长时间包装或收存藏品，尽量不以塑胶材料包装，或是换以无酸材料。

Bubble wrap is a pliable transparent plastic material used for packing fragile items. Regularly spaced, protruding air-filled hemispheres (bubbles) provide cushioning for fragile items.

"Bubble wrap" is a generic trademark owned by Sealed Air Corporation. In 1957 two inventors named Alfred Fielding and Marc Chavannes were attempting to create a three-dimensional plastic wallpaper. Although the idea was a failure, they found that what they did make could be used as packing material. Sealed Air Corp. was co-founded by Alfred Fielding in 1960.
