Stretch film is an elastic plastic used to wrap or secure goods, especially on pallets. Stretch film has the ability to stretch (stretchability) so that it can hold the load tightly, protect the product and maintain stability during the transportation or storage process. One important aspect that determines its performance is thickness. This article will discuss what is meant by stretch film thickness, how it is measured, and its effect on packaging applications.
Stretch film thickness refers to the physical measure of how thick the film is. This thickness is usually measured in microns (µm). One micron is equivalent to 0.001 millimeters (mm). Stretch film generally has a thickness between 8µm to 35µm, depending on the application. Stretch film thickness is usually measured using specialized tools such as micrometers. To ensure consistency and quality, measurements are taken at multiple points on the film surface. Uniform thickness is essential to avoid low spots that can reduce load stability.
Thickness Effect on Performance
1. Tensile Strength
Stretch film with a higher thickness has greater tensile strength, allowing it to wrap heavy and irregular loads more securely without tearing or damage. This is important for maintaining the stability and integrity of the load during transportation.
2.Level of Protection
Thicker stretch films offer optimal protection against dust, moisture and physical damage. This is especially useful for products that are sensitive to environmental conditions or products that require extra protection.
3. Efficiency of Use
Thicker stretch films can reduce the number of layers required for wrapping. This can reduce the time and labor required and reduce waste.
Choosing the right stretch film thickness depends on factors such as the weight, shape, and fragility of the load, as well as transportation or storage conditions. By understanding the specific needs of packaging applications, companies can optimize stretch film usage while ensuring product safety and sustainability.
