Half Value Layer (HVL) of glasses were determined and compared with the some standard shielding materials.
Therefore, it is essential to study the absorption of gamma-ray in materials.
The glass materials can be used for the radiation shielding material with the advantage is the high transparent in the visible region.
The HVL decrease with increasing of mol % of bismuth oxide and show better than some standard materials.

Plastic film assumes a large role as packaging material in our life.
It is considered that enough high peel strength and tensile strength are needed for liquid package material.
Introduction Plastic film assumes a large role as packaging material in our life.
Though, because laminated film is compound material, elements that influence peel strength, tensile strength and tear strength are range.
