Hard Shell Gelatin
Several gelatin types may be used in the
manufacture of hard capsules. Traditionally
these have all been relatively high Bloom
strength gelatins in the range 230-265g
More recently, limed gelatins with lower
Bloom strengths in the range 180-230g (BSI)
have been used. Sterling produces limed
gelatins with Bloom strength in the range
150-270g Bloom, which normally represent
a major proportion of the gelatin blend
used in hard capsule manufacture.
Soft Shell Gelatin Capsules
160 Bloom limed gelatin has traditionally
been the standard gelatin for the manufacture
of soft shell capsules.
