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 PP heat sealing and complementary PP homo-polymer grades for BOPP films. True to our company's motto, we keep discovering new products and material solutions that help our customers realise eco-efficient packages. What is more, Borealis innovations help reducing CO2 emissions and improve the circularity of flexible packaging.

Provider of high-performance PP heat sealing and PP homo-polymer 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 heat seal grades TD310BF, TD312BF and TD315BF provide an excellent thickness profile when used on high-speed BOPP lines.

Borealis also supplies non-phthalate based PP homo-polymer products for the core layer, including:

• High clean PP homo-polymer (HC101BF)
• High stiff and high clean PP homo-polymer (HC110BF)
