  • Process for preparing filled hard-shell capsules with (meth)acrylate copolymer based coatings with a capsule-filling machine
    Patent number: 11523992
    Abstract: A process can be used for preparing a polymer coated hard-shell capsule, filled with a fill containing a biologically active ingredient. The hard-shell capsule contains a body and a cap, and in a closed state, the cap overlaps the body either in a pre-locked state or in a final-locked state. The material of the body and the cap contains an ethyl-, methyl-, or propyl-ether of cellulose, starch, or pullulan. The hard-shell capsule is coated with a coating layer that covers the hard-shell capsule in the pre-locked state. The coating layer contains one or more (meth)acrylate copolymers, where the coating layer is present in an amount of about 1 to 5.8 mg/cm2. The process involves providing the polymer-coated hard-shell capsule in the pre-locked state to a capsule-filling machine, separating the body and the cap, filling the body with the fill, and rejoining the body and the cap in the final-locked state.
