Clariant launches Senseaction Color masterbatches for plastic caps and closures
Clariant launched the Senseaction line of colour masterbatches intended for use in the production of caps and closures used on
bottled water packaging. Senseaction masterbatches, which are available in a wide range of colours, are specially formulated, processed, tested, and certified to be free of detectable negative organoleptic (taste and odor) effects.
The new line was developed to meet the high demands of bottled water producers and the
processors who supply them with caps and closures, which are typically made of HDPE or
polypropylene. Although processors have always utilised safe, food-grade pigments to colour caps and
closures, there is the potential that pigments in them could contain trace elements that, even in
minute quantities, could impart a detectable taste or odor to bottled water or beverages.
The Senseaction product range is designed to reduce the potential impact, explains Alessandro
Dulli, Global Head of Packaging for Clariant Masterbatches: “This portfolio will help brand owners
make good looking caps that reflect positively on their brand, free of undesirable organoleptic
influences.” He adds that the new masterbatch brand is built around three pillars: material selection,
a dedicated manufacturing process, and a testing/certification process prior to sale.
Seneaction colour masterbatches start with raw materials that are food-contact compliant,
including pigments and carrier resins that are carefully selected for use in sensitive organoleptic
applications. Manufacturing takes place exclusively using dedicated processes and special
equipment at a dedicated masterbatch site. When manufacturing is complete, each lot of
Seneaction masterbatch undergoes an exposure in water, which then is tested according to DIN
10995 at an independent external laboratory. A panel of professional testers, specially selected for
their acute sense of taste and smell, evaluate the samples for adverse organoleptic effects.
