Another straw available is the novelty straw. This is a straw, which will change colour when inserted into a cold drink. The straw, which is outside the liquid, remains the same whilst the part of the straw in the cold drink changes colour.
The straws are manufactured from 100% Food grade polypropylene to ensure safety for the user. These straws conform to ASTM/FDA Standards. The OPP wrapper is also approved food grade. At the end of the straw manufacturing process the straws are packaged by hand into a mega carton. Great care has to be applied during final packaging, as the contract carton filler needs a continuous flow to prevent snarling.
