Core tips: raw materials of PVC series medical composite hard tablets

PVC pharmaceutical tablets must be produced in a clean workshop meeting the production requirements of pharmaceutical packaging materials and approved by SDA for registration before they can be used for the production of composite hard tablets.

The raw materials of PVC series medical composite hard tablets mainly include PVC medical tablets, PVDC lotion or resin, PE film, adhesive, etc. The selection of raw materials should not only consider the processability and secondary processability (PTP packaging), but also consider the hygiene of drug production, both of which are indispensable. Once the composition and structure of the material are determined, the packaging material factory cannot easily change it and affect the drug quality.
