Shrink films come in various types, each offering specific benefits depending on the application. The three most common types are PVC, Polyolefin, and Polyethylene Shrink Films. Understanding the differences between these films can help businesses make the right choice for their packaging needs.
Material Composition:
PVC Shrink Film: Made from polyvinyl chloride, PVC films are known for their high clarity and low cost but come with environmental concerns.
Polyolefin Shrink Film: Made from a blend of polyethylene and polypropylene, Polyolefin films are more eco-friendly and recyclable compared to PVC.
Polyethylene Shrink Film: This film is typically used for low-cost, low-performance applications and has a lower shrinkage rate than the other two films.
Shrinkage and Flexibility:
PVC Shrink Film: Shrinks quickly but can become brittle in cold temperatures.
Polyolefin Shrink Film: Offers consistent and even shrinkage and is more flexible after shrinking.
Polyethylene Shrink Film: Typically provides less shrinkage and is more rigid, making it less suitable for products requiring tight wraps.
Durability:
PVC Shrink Film: Offers excellent puncture resistance, but it is less flexible and can crack under colder conditions.
Polyolefin Shrink Film: Offers greater durability and flexibility, making it more suitable for a variety of applications.
Polyethylene Shrink Film: While tough, it lacks the flexibility of Polyolefin and tends to offer a lower quality appearance.
In summary, Polyolefin Shrink Film is the ideal choice for most applications due to its superior shrinkage performance, clarity, flexibility, and eco-friendly properties.
