## Answer.

### 1. How does stretch film adhere to surfaces?

Stretch film works by utilizing its elastic properties to conform and adhere to surfaces. When the film is stretched around an object, it creates tension that allows it to cling to itself and the surface being wrapped. This adhesion helps keep the items securely in place and protected during transport or storage.

### 2. What properties does stretch film have in order to securely wrap items?

Stretch film is made from a thin, stretchable plastic material such as polyethylene. It has the ability to stretch and elongate without breaking, which allows it to tightly wrap around irregularly shaped items. Additionally, stretch film has good tensile strength and puncture resistance, providing durability and protection against tears or damage.

### 3. What are some common uses of stretch film?

Stretch film is commonly used in various industries for packaging and securing items. It is widely used in logistics and shipping for palletizing and protecting goods during transit. Stretch film is also used for bundling together items for retail display or storage. In households, stretch film is often used for wrapping and preserving food items to keep them fresh.

In conclusion, stretch film works by adhering to surfaces through its elastic properties, which allow it to conform and cling securely. Its stretchability and strength make it an ideal packaging material for a wide range of applications in industries and households.
