Polypropylene (PP) Cores

Applications

PP cores are particularly suitable for industrial environments requiring rigidity and consistent dimensional stability:

• Plastic film industry: Heat-resistant PP cores are ideal for winding technical plastic films exposed to thermal variations.
• Food industry: As a safe material compliant with food-contact regulations, PP is suitable for films and sheets intended for direct or indirect contact with food products.
• General industrial applications: Polypropylene is widely used in environments requiring lightness, rigidity and chemical resistance.

Technical information

• Inner diameters: Ø 76 to Ø 102 mm (other diameters available on request)
• Inner finish: smooth or grooved
• Laize (width): 100 to 4000 mm (inline cutting)
• Material: Polypropylene (PP)

These cores can be customised to match your tolerance, finish and performance requirements.

Material: Polypropylene (PP)

Key properties

Polypropylene (PP) is a thermoplastic polymer belonging to the polyolefin family, like HDPE.

Its semi-crystalline structure provides an excellent balance of rigidity, lightness and thermal resistance.

It is a reference material for manufacturing cores subjected to moderate mechanical and thermal stresses, offering good chemical resistance and remarkable durability.

Main technical properties:

• Density: approx. 0.90 g/cm³ — lighter than HDPE, facilitating handling
• Balanced mechanical strength: good rigidity combined with controlled flexibility, ideal for film winding
• Heat resistance: withstands continuous temperatures up to 100 °C with excellent dimensional stability
• Chemical resistance: unaffected by most acids, bases, solvents and oils
• Food-contact compliant: meets European regulations (EU Regulation No. 10/2011)
• Lightweight and durable: reduced weight, good fatigue resistance and long service life
• Recyclability: 100% recyclable, supporting a circular-economy approach

These features make PP a versatile material ideally suited to industrial, logistics and food-processing environments.

PP variants and possible fillers

To meet the specific requirements of each application, ABI Profils works with a wide range of technical formulations and functional additives:

• Virgin PP: premium grade offering maximum surface quality and mechanical stability, ideal for food or technical applications
• Recycled PP: material-recovery grade that reduces environmental impact without compromising mechanical performance
• UV stabilisers: protect the material from light-induced degradation and extend outdoor durability
• Mineral fillers (talc, calcium carbonate): increase rigidity, improve heat resistance and reduce deformation
• Antistatic additives: reduce dust attraction and prevent electrostatic discharge in sensitive environments
• Custom colouring: mass pigmentation for easy identification or specific aesthetic requirements

Thanks to this expertise, ABI Profils tailors each PP formulation to your mechanical, thermal and regulatory constraints, ensuring high-performance, safe and durable plastic cores.
