At present, blister packaging is becoming more and more common for health food, pharmaceutical tablet and capsule packaging. It is also referred to as PTP(PressThroughPackaging) packaging. The PTP aluminum foil is densely sealed on the hard plastic sheet of polyvinyl chloride (PVC).
The structure of PTP foil consists of OP, outer printing layer, aluminum foil substrate (from Haomei), inner printing layer, adhesive (VC), etc. The aluminum foil for PTP packaging is 8011-H18 and 8011-O aluminum foil. The thickness is 0.016-0.04mm.
It is estimated that PTP packaging will account for about 60% to 70% of the future pharmaceutical tablet and capsule packaging, which is one of the most promising pharmaceutical packaging materials. Then how to get the quality PTP blister foil? There are four tips the aluminum foil manufacturer need to notice during the manufacturing process.
1. We must first control the quality from the source and strictly inspect the ingot quality.
2. In the rolling process, we can get a better surface through the cleaning and roughness control of the rolls, the selection of rolling oil, reducing the viscosity of the rolling oil, and controlling the speed of the machine.
3. In the slitting process, it is necessary to ensure that the edge of the aluminum coil is neat when cutting and no edge curling is allowed.
4. In the annealing process, we should control the the annealing time and annealing temperature according to the performance requirements of medical aluminum foil. In addition, the surface of aluminum foil should be no oil marks.
