PVC medicinal tablets are mainly made of polyvinyl chloride (PVC) resin with certain processing aids added, and are produced through extrusion, calendering and other processing methods. They are novel packaging material that meets medicinal requirements. It independently separates each tablet, pill and capsule, making it the smallest packaging unit. The accuracy and safety of using medicines are greatly improved.
Moreover, due to the simple processing method, small investment, easy molding and processing, etc., the medicine The factory's production costs have dropped significantly and production efficiency has been greatly improved. In the early 1990s, almost all pharmaceutical factories were willing to use this kind of packaging to produce tablets, pills and capsules. This development trend continues to this day.
PVC medicinal tablets account for more than 95% of domestic PTP packaging materials. The development trend of PTP aluminum plastic packaging abroad is currently dominated by PVC materials, but now there are packaging materials such as PP, PET, PS, etc., but there is a gap in overall performance compared with PVC. The most important thing is the appearance of pharmaceutical packaging. There is no new image. Therefore, the packaging materials used in PTP aluminum-plastic packaging are mainly PVC materials abroad, accounting for about 60%. Most of the rest are composite packaging materials, and other single packaging materials account for a small proportion. From the perspective of growth rate, the growth rate of composite packaging materials is 3-4 times that of single packaging materials.
The raw materials of PVC medicinal tablets mainly include PVC resin, stabilizers, processing aids, reinforcing agents, lubricants, plasticizers, etc. The selection of raw materials must not only consider processability and secondary processing (PTP packaging), but also consider the hygiene of pharmaceutical production, both of which are indispensable. In fact, PVC hard sheets contain about 90% PVC resin, and additives only account for a small part.
The specific ingredients are as follows:
| PVC resin | 88-92% |
| stabilizer | 1.5% |
| reinforcing agent | 4.5% |
| processing aid | 1-1.5 % |
| Plasticizer | 0 – 1% |
| Lubricant | 1.5 – 2% |
