BOPP & Heat Seal

New products and material solutions for BOPP films that help our customers realise continuous improvements

Biaxially oriented polypropylene (BOPP) films are used in a variety of modern applications, including:

• Flexible food packaging
• Printing and lamination films
• Metallised barrier films
• Stationery
• Flower sleeves
• Pressure-sensitive adhesive tape
• Cable wrap and insulation

As one of the leading producers of polyolefins in Europe, we offer a range of high-performance homopolymers and heat sealing grades for BOPP films. True to our company's motto, we keep discovering new products and material solutions that help our customers realise continuous improvements when it comes to throughput and stretching ratios in manufacturing. What is more, Borealis innovations help reduce BOPP production costs.

Provider of high-performance homopolymers and heat sealing grades

Although the sealing layers are rather thin, they provide the BOPP films with surface functionality and play an important role for post-handling processes. Among the key properties of our heat seal grades:

• Low seal initiation temperature (SIT)
• Very good seal strength
• Excellent hot-tack performance
• Superior optical properties
• Exceptionally low extractables providing:
  • Low tackiness at sealing jaws
  • Low blooming and thus good optical properties
  • Stable surface properties, perfect for metallisation
• Well-balanced rheology to enhance an improved thickness profile
• Easy stretching

Our newly developed Borealis TD310BF, TD315BF and TD309BF heat seal grades provide an excellent thickness profile when used in high-speed BOPP lines.

Borealis also supplies BOPP homopolymer products for the core layer, including:

• Multi-purpose non-phthalate homo PP (HC101BF)
• High stiffness and non-phthalate homo PP (HC110BF)
