## Claims

### Claim 1

A three-layer film comprising:
(I) a low density polyethylene, an ethylene-vinyl acetate copolymer, an ethylene-butyl acrylate copolymer, or mixtures thereof;
(II) an additive mixture comprising components (A) and (B),
wherein:
component (A) is a compound of the formula (I-1-a), or a mixture of the compounds of the formulae (I-1-a) and (II-1-a):
wherein n following the bracket of formula (I-1-a) is a number from 1 to 10, and
wherein two outer layers of the three-layer film comprise the (I) and component (A), and a middle layer of the three-layer film further comprises the (I) and (II), wherein the component (B) is at least one heat reflecting interference pigment, which is in the form of platelets coated with one or more metal oxides, wherein the platelets comprise layered silicate, glass, or ceramic.

### Claim 2 (depends on 1)

The three-layer film of claim 1, further comprising a UV absorber.

### Claim 3 (depends on 1)

### Claim 4 (depends on 1)

The three-layer film of claim 1, further comprising an additive selected from an antioxidant, a slip agent, an anti-block agent, a thermal filler, a pigment, an anti-fog agent and/or an anti-mist agent.

### Claim 5 (depends on 1)

The three-layer film of claim 1, wherein the platelets comprise layered silicate.

### Claim 6 (depends on 5)

The three-layer film of claim 5, wherein the layered silicate is mica, pyrophyllite, sericite, talc, or kaolin.
