Ultradur® FC grades: the new sustainable performance kit for coffee capsules.

Ultradur® B1520 FC R01 is a specially developed high flowability PBT for packaging applications. Besides the well-known advantages of Ultradur® – stiffness, strength, thermal stability and chemical resistance – the easy-flowing Ultradur® variant offers more. Combined with other grades (for example barrier or weight optimized) it even multiplies its performance.

Overview

Ultradur® B1520 FC R01 at a glance:

  • Easy flowing PBT grade
  • Food contact approved
  • Excellent barrier properties:

    OTR: 24 cm³ 100 μm / (m² d bar)

    WVTR: 2,5 g 100 μm / (m² d 85% r.H.)

    MVR: 110 cm³/10 min

  • High rigidity and strength
  • Chemical resistance

Our basic grade

The outstanding heat stability of Ultradur® B1520 FC R01 allows sterilization, hot filling, microwaving and makes the products dishwasher safe. The shape of the stiff and stable thin walled injection-molded packaging can be freely chosen due to its excellent barrier properties. There is no need for a 100% complete labeling to provide a barrier. The easy processing of Ultradur® enables the usage on standard filling lines. Ultradur® B1520 FC R01 is certified for food contact, which makes this grade suitable for thin-walled (injection-molded) packaging for cosmetics and food products.

 

Protection against moisture and oxygen

Ultradur® B1520 FC R01 is the product of choice when it comes to single layer aroma sealed packaging. The well balanced barrier properties against moisture and oxygen make a secondary packaging redundant. Thus, the new capsules have great advantages compared to other injection-molded or multilayered thermoformed capsules. And on top – due to the high stiffness of Ultradur® the capsules can be very thin which is a prerequisite for economic and ecological production.

 

Ultradur® keeps food fresh longer

After using another material, the delicatessen manufacturer Gautschi switched to PBT tubs made of Ultradur® B1520 FC R01. In this new PBT variant, products stay fresh considerably longer, as Gautschi confirms. The excellent barrier properties of this new PBT material against moisture and oxygen also efficiently help to retain the aroma.

Sustainability

  • BASF biomass balance (BMB) approach leads to 40 % saving of CO2 compared to the fossil version.
  • ChemCyclingTM also leads to a CO2 reduction up to 50 % and post-consumer plastic waste reduction, using this waste to generate pyrolysis oil.
  • Bio-based materials lead to higher water and land usage, while reducing CO2 emissions.

  • Melt temperatures: 260 – 280°C, preferred 275°C
  • Mold temperatures: 20 – 60°C, preferred 40°C
  • Moisture and drying: Max moisture content granulate: 0,04%; Predrying of granulate with dry air dryer or vacuum dryer: 80°C - 120°C, 4h
  • Plasticizing: Peripheral screw speed: max 0,25 m/s; Dosing: max 1-2 x screw diameter
  • Screw Design: Single-flighted, shallow-cut three-section screws having a L / D ratio of 20 - 23 are suitable for processing Ultradur®.
  • Hot Runner: Good thermal insulation necessary, recrystallization temperature of PBT is about 202°C, therefore material freezes at higher temperature level in comparison to e.g. PP, open nozzle or shut-off nozzle.
