Blister packs are typically sealed using a heat-sealing process. Here are the steps to seal a blister pack:
1.Place the blister pack on a flat surface, with the blister cavity facing up.
2.Fill the blister cavity with the product, if it hasn't been filled already.
3.Cut a sheet of heat-sealable material to fit over the blister pack. The material should be slightly larger than the blister pack, to allow for a seal around the edges.
4.Place the sheet of heat-sealable material over the blister pack, so that it covers the cavity and extends beyond the edges of the blister pack.
5.Apply heat and pressure to the sheet of material, using a heat-sealing machine or tool. The heat melts the material, which bonds to the blister pack and forms a seal around the edges of the blister cavity.
6.Allow the blister pack to cool and then inspect the seal to make sure it is secure and airtight.
Note that the specific heat-sealing process may vary depending on the materials used, the size and shape of the blister pack, and the equipment available.
