Patent ID: 7018821

Claim:
A highly impact-resistant granule comprising a) an impact-sensitive particle including an active ingredient and b) a flexible film comprising a polymer surrounding said impact-sensitive particle, wherein said film has an elongation upon break of at least about 30% , determined by dividing gage length measured after breakage of the film due to applying tensile strain by original gage length of the film of 10–100 mm prior to applying tensile strain, and said film comprises less than about 20% by weight of the highly impact-resistant granule, wherein said impact-sensitive particle has more than about 10% mass attrition and said highly impact-resistant granule has less than about 5% mass attrition, wherein mass attrition is determined by a Repeated Impact Test (RIT), using 216,000 collisions at 8.7 m/s and an amplitude of 1.5 cm.
