Packaging adhesive film and photovoltaic module

The utility model belongs to the field of photovoltaic technology. The utility model discloses a packaging adhesive film which comprises a foam hole layer, and the foam hole layer comprises foam holes. The foam pores with the average diameter c of 60-300 [mu] m are used as large foam pores, the foam pores with the average diameter c of 1-50 [mu] m are used as small foam pores, and the number percentage of the large foam pores to the small foam pores in unit area is (10: 90)-(70: 30); the average diameter c is equal to (x + y + z)/3, x is the size of the foam hole in the extending direction of the packaging adhesive film, y is the size of the foam hole in the transverse direction of the packaging adhesive film, and z is the size of the foam hole in the thickness direction of the packaging adhesive film. The utility model also discloses a photovoltaic module. The packaging adhesive film has excellent insulation performance and relatively high toughness, the subfissure rate of a battery piece can be reduced, and
