It is intended to produce a band seal for hard capsules having PEG (in particular, low-molecular weight PEG such as PEG 200 to 600) encapsulated therein, in which the leakage of the contents from the space between the body part and the cap part can be effectively prevented; and a solution for preparing the same. It is also intended to provide hard capsules having PEG (in particular, low-molecular weight PEG such as PEG 200 to 600) encapsulated therein which is free from the problem of the leakage of the contents from the space between the body part and the cap part, and a method of preparing the same. The band seal as described above can be prepared by using, as the main component, polyvinyl alcohol, a polyvinyl alcohol copolymer or a mixture of the same. |
