Encapsulated-air plastic (bubble) sheeting is packing material made of air bubbles that are encased between two poly sheets as they are sealed together. This process allows encapsulated air to provide a cushion to protect against shock.
Encapsulated air provides good cushioning for lightweight items and can be cut to wrap virtually any shape or sized product. It should not be used to wrap heavyweight products. When using encapsulated-air plastic sheeting, use several layers to ensure that the entire product is protected, including corners and edges.
Small cell bubble sheeting is packing material made of 1/4 inch (0.64 cm) tall air bubbles and provides surface protection. Large cell bubble sheeting is packing material made of 1/2 inch (1.27 cm) air bubbles and is used for cushioning.
Wrap each item separately and place in a strong container. Fragile items will need suitable separation from each other, and from the corners, sides, top, and bottom of the box. Each item should be surrounded by at least two inches (5.08 cm) of encapsulated-air plastic sheeting and placed at least two inches (5.08 cm) away from the box walls. This prevents product-against-product damage and protects the contents from shock and vibration, which can pass from the outside of the box to the contents. Use enough sheeting to ensure that the contents cannot move when you shake the box.
