Stretch film and cling wrap are not the same; they are two distinct packaging materials with different purposes and characteristics.
Stretch film, also known as stretch wrap, is a highly elastic plastic film used for securing and stabilizing products during shipping and transportation. It is commonly made from Linear low-density polyethylene (LLDPE). The primary function of stretch film is to tightly bind items together on pallets, ensuring they remain intact and protected. Stretch film offers excellent load containment and resilience due to its stretchability.
Cling film, also known as plastic wrap, food wrap, or saran wrap, is a thin plastic film used primarily for food preservation. It adheres to itself and to various surfaces, creating an airtight and protective seal. Cling film is commonly used in kitchens to cover food containers and wrap perishable items to prevent moisture and air exposure.
While both stretch film and cling film are made from plastic, they serve different purposes and exhibit distinct characteristics. Stretch film is thicker, stronger, and designed to secure larger loads for transport. Cling film, on the other hand, is thinner and more pliable, making it suitable for wrapping and protecting smaller items.
In conclusion, stretch film and cling film are not the same. Stretch film is used for shipping and securing larger items, while cling film is used primarily for food preservation and wrapping smaller objects. It’s essential to choose the right packaging material based on the specific requirements of your application.
