Stretch wrap is a type of plastic film used to secure items together for shipping or storage. Stretch film comes in different forms such as cast, blown, and pre-stretched. There is a special feature of each type and a special application. We’ll consider the distinctions between cast, blown, and pre-stretched stretch film so you can choose the right one for your application.
Properties and Benefits
Cast stretch film is produced by melting plastic and spreading it into a thin sheet. It is clear film, so you’re able to see what is wrapped below. Stretch film is also quiet when you apply it so it is good in a quiet environment where noise should be minimal.
Blown stretch film is manufactured by blowing heated resin to create a thin gauge film. This style of stretch film offers greater stretch and more tear resistance than cast stretch film. Blown stretch film is also not as transparent, which can protect items from sunlight damage.
Pre-stretched stretch film is produced by stretching the film during its production process, thereby reducing the gauge (thickness) of the film while improving the stretchiness of the film. It’s easier to work with, and requires less material, which can be cheaper. This pre-stretched stretch film also clings to itself and secures the load and has a high resistance to puncture.
Advantages and Applications
Machine stretch film is commonly used to wrap pallets and skids to secure and protect product during storage and shipment. Its translucent nature is good for stores that care about appearance. It is also perfect for wrapping things that aren't just regular shapes.
Blown stretch film is ideal for heavy or sharp corners that stretch film will not perform as well as blown.
Its high puncture resistance is ideal for wrapping sharp or jagged items. Blown stretch wrap is also good for outdoor or long-term storage and can be used as a UV resistant film because it protects from solar rays.
Pre-stretched Stretch Film Series is favored in busy shipping places because it can help work faster and use less. Its strong load-holding strength is beneficial for heavy or wobbly articles. Pre-stretched stretch wrap is also suitable for wrapping lightweight items that tend to move inside package for its excellent self-adhering.
The Benefits of Pre-Stretched Strapping Film
The prestretch stretch film has a lot of advantages compared to the regular pe stretch film. It is also more workable, requiring less muscle to stretch it around stuff. This could be helpful for workers to not feel so tired and to be able to work better. Pre stretched stretch film is also made using less material, which can save money in the long run.
Selecting The Right Cast, Blown, or Pre-Stretched Stretch Film
When choosing between cast, blown and pre-stretched stretch film, consider what it will be used for. If you need a clear film for visual inspection or stores, you’ll want cast stretch film. If you need to wrap heavy or sharp objects that are not fragile, consider blown stretch wrap for hole resistance. For fast-paced shipping or non-stable loads, eliminate tension loss with pre-stretched compostable stretch film.
