Tinted Wraps: Benefits of Color Stretch Film

Stretch film is also commonly known as stretch wrap. Both terms are used interchangeably in the packaging and shipping industries to describe the elastic plastic film used for wrapping and securing products. Other alternative names include pallet wrap, plastic wrap, or wrapping film, which highlight the film's primary functions of wrapping around items to hold them together and protect them during transit and storage. In some regions or industries, it may also be referred to as cling film, although this term is more commonly associated with food-grade plastic wrap used in kitchens. It's important to note that stretch film differs from shrink wrap, which is a different type of packaging material that requires heat to shrink tightly around products. Understanding these various terms is helpful when selecting the appropriate packaging materials and communicating effectively within the industry. Regardless of the name used, the essential characteristics and uses of the material remain the same: to secure, protect, and stabilize products during handling, shipping, and storage.

The shelf life of stretch film refers to the period during which the film retains its optimal physical and mechanical properties when stored under recommended conditions. Typically, stretch film has a shelf life of approximately 12 to 18 months from the date of manufacture. However, this can vary depending on factors such as the film's composition, storage environment, and exposure to environmental elements. To maximize the shelf life of stretch film, it should be stored in a cool, dry environment, away from direct sunlight and sources of heat. Ideal storage temperatures range from 50°F to 77°F (10°C to 25°C), with relative humidity below 80%. Exposure to high temperatures can cause the film to lose its elasticity and become brittle, while excessive humidity may affect its cling properties. Ultraviolet (UV) light from sunlight can degrade the film, leading to a breakdown of the polymer chains and resulting in reduced strength and performance. Therefore, storing stretch film away from windows or in UV-protected packaging can help prolong its shelf life. It's also important to avoid stacking heavy objects on top of stored rolls, as this can deform the cores and make the film difficult to unwind during application. Rotating stock (first-in, first-out) ensures that older film is used before it potentially degrades. After the shelf life has elapsed, stretch film may still be usable, but its performance could be compromised. Signs of degradation include a loss of elasticity, reduced cling, brittleness, or discoloration. Using degraded film can lead to insufficient load containment, increasing the risk of product damage during transit.
