Stretch film is a type of plastic film that is used to wrap and secure loads. It is made from a variety of materials, including polyethylene (PE), polypropylene (PP), and polyester (PET). Stretch film is available in a variety of widths, thicknesses, and tensile strengths to meet the needs of different applications.
Types of Stretch Film by Material
The most common type of stretch film is made from polyethylene (PE). PE stretch film is relatively inexpensive and easy to use. It is available in a variety of colors, including clear, black, and white. PE stretch film is often used in food and beverage applications, as well as in the transportation and storage of other goods.
Another common type of stretch film is made from polypropylene (PP). PP stretch film is stronger and more durable than PE stretch film. It is also more resistant to chemicals and moisture. PP stretch film is often used in industrial applications, such as the packaging of heavy or bulky goods.
Polyester (PET) stretch film is the strongest and most durable type of stretch film. It is also the most expensive. PET stretch film is often used in applications where maximum strength and durability are required, such as the packaging of hazardous materials.
Types of Stretch Film by Application
Stretch film is used in a variety of applications, including:
To secure loads for transportation and storage
To protect products from damage
To prevent product loss
To reduce labor costs
The type of stretch film that is best suited for a particular application will depend on a number of factors, including the weight and size of the load, the environment in which the load will be stored or transported, and the desired level of security.
Hand-Applied Stretch Film
Hand-applied stretch film is the simplest type of stretch film to use. It is available in rolls that are typically 10-15 feet long and 1-2 inches wide. Hand-applied stretch film is often used for small or lightweight loads.
Machine-Applied Stretch Film
Machine-applied stretch film is used for larger or heavier loads. It is available in rolls that are typically 100-200 feet long and 2-4 inches wide. Machine-applied stretch film can be used to apply a much tighter wrap than hand-applied stretch film, which can provide greater security and protection.
Pre-Stretched Stretch Film
Pre-stretched stretch film is stretch film that has been stretched to a predetermined percentage before it is applied. Pre-stretched stretch film provides a tighter wrap than non-pre-stretched stretch film, which can improve security and reduce labor costs.
Colored Stretch Film
Colored stretch film is used to provide identification or to make it easier to see loads that are stored in dimly lit areas. Colored stretch film is available in a variety of colors, including clear, black, and white.
Printed Stretch Film
Printed stretch film is used to display logos or other information. Printed stretch film is available in a variety of colors and designs.
Conclusion
Stretch film is a versatile and effective packaging material that can be used in a variety of applications. The type of stretch film that is best suited for a particular application will depend on several factors, including the weight and size of the load, the environment in which the load will be stored or transported, and the desired level of security.
