Shrink Films
Our shrink films – including those with oxygen barriers – are special plastic films that change size and shape when heated by shrinking. This effect occurs because the molecular structure of the material is activated when heated, causing the film to shrink. As roll stock, these films are processed on industrial packaging machines.
Characteristics of Shrink Films
- Shrink Behavior: Shrinks by a certain percentage when heated (usually between 20% and 50%).
- Flexibility: Flexible and easy to process before shrinking.
- High Barrier Properties: Provides protection against external influences such as oxygen, moisture, and mechanical damage.
- Transparency and Gloss: Shrink films can be transparent or printed, allowing clear visibility of the product.
Materials for Shrink Films
- PPE, PET, PA, PP, EVOH: Specifically designed for food packaging in the meat and cheese industries.
- Polyolefin (POF): Immensely popular for shrink packaging due to its flexibility and durability. Ideal for products requiring high transparency.
Applications of Shrink Films
Product Packaging
- Food: Shrink films are used for packaging foods such as sausages, cheese, or beverage bottles.
Advantages of Shrink Films
- Efficient Packaging: Shrink film conforms to the product’s shape, enabling space-saving packaging.
- Presentation: Shrink films securely and transparently package the product, providing high visibility.
- Protection: Extends product shelf life by protecting against moisture, light, and oxygen.
- Durability: Provides a strong and long-lasting packaging solution that keeps the product secure.
Summary
Shrink films are versatile and offer numerous benefits, especially for the packaging and presentation of products.
