Abstract
The present invention relates to a medical packaging film containing a laminate of a first layer formed of a no-antistatic agent-containing thermoplastic resin formation layer; a second layer formed of a polymer antistatic agent-containing thermoplastic resin formation layer containing a potassium ionomer in an amount of C wt % (10<C<30); and a third layer formed of the thermoplastic resin formation layer, and the laminate provides an amount of a water-elutable alkali component being at most 0.01 mmol equivalent per g in total of 1 cm2 pieces, and in which the first layer has a thickness of L1 m, and the second layer has a potassium ionomer concentration of C′2 vol % and a thickness of L2 m, satisfying the formula 2≤L1≤(5×L2×C′2)/100+5.
Claims11
A medical packaging film comprising a laminate of at least three layers,
- wherein the laminate comprises:
- a first layer that is an innermost layer in contact with a medicine and formed of a no-antistatic agent-containing thermoplastic resin formation layer;
- a second layer formed of a polymer antistatic agent-containing thermoplastic resin formation layer comprising a polymer antistatic agent that is a potassium ionomer in an amount of C wt % (10<C<30) in a single layer;
- and
- a third layer that is formed of a thermoplastic resin formation layer, and the laminate provides an amount of a water-elutable alkali component being at most 0.01 mmol equivalent per 5 g in total of 1 cm2 pieces, and
- wherein the first layer has a thickness of L1 μm, the second layer has a potassium ionomer concentration of C′2 vol % and the second layer has a thickness of L2 μm, satisfying the following formula (1):
- 2≤L1≤(5×L2×C′2)/100+5 (1).
