Cast polypropylene film

Cast polypropylene (CPP) film is a high-performance solution developed for flexible packaging applications that require advanced technical properties and high customisation capabilities. Thanks to its excellent thermal, mechanical and optical performance, it is especially popular in industries such as food, pharmaceuticals, health and industrial settings.

Highly versatile for technical packaging

Cast polypropylene film is ideal for a wide range of applications, such as:

• Thermoformed packaging
• Lidding films
• Flow pack
• Wicket bags for food products
• Packaging for pharmaceutical or surgical products

Produced by cast extrusion, this film enables a precise control of the gauge, guaranteeing uniformity, dimensional stability and excellent results in conversion processes. Thanks to thermal resistance, it can be used in demanding processes such as pasteurisation, sterilisation, autoclave or microwave processing without compromising container integrity.

Customised printing and finishes 

One of the main advantages of polypropylene film is its compatibility with high–definition printing using flexographic or rotogravure technology, offering high–impact visuals. This makes it ideal for brands that require an attractive and functional container that is aligned with the product‘s visual identity. 
It can also include surface treatments, metallising, barrier coatings and peel–away formulations, thus adapting to any technical project. 

Main technical properties of polypropylene film 

Mechanical and thermal performance 

  • Highly resistant to blows, punctures and tears.

  • Consistent thickness profile starting at 20 microns

  • Structures at different levels of rigidity and resistance available.

  • Melting points starting at 85 °C, adjustable depending on the application.

  • Dimensional stability and good processability.

  • Retort formulations for highly-demanding thermal conditions.

  • Highly resistant to humidity, grease and chemical agents.

  • Excellent sealing capability under difficult conditions, with suspended powder, liquids, oils, etc.

Customisation and industrial efficiency

  • Surface treatment on one or both sides.

  • Natural or coloured finishes available.

  • Option to include fog-proof and static-proof additives.

  • Wide range of formulations.

  • Compatible with automatic packaging lines (VFFS, HFFS, FFS, thermoformed)

  • Specific development upon request: multi-layer, thermosealable, and peel-off structures, among others.

  • The Coefficient of Friction can be adapted to the application requirements.

Sustainability 

  • 100% recyclable, suitable for single-material structures.

  • Eco-efficient alternatives that facilitate compliance with environmental regulations.
