    DETAILED DESCRIPTION OF THE INVENTION

    [0023] In this detailed description, the metallized shrink film according to the invention is explained for better understanding of the subject in an unconstrained manner.

    [0024] The invention relates to a composite metallized shrink film (1) with heat insulating properties obtained by metallization through applying metal vapor on one or two sides of a shrink film according to prior art as shown in FIG. 1.

    [0025] The invention relates to a metallized shrink film (1) with polymer-based film layer (10), comprising a metallized surface layer (20) applied to at least one side of said polymer-based film layer (10) as shown in FIG. 2.

    [0026] According to an embodiment of the invention, it comprises a metallized surface layer (20) applied to both sides of said polymer-based film layer (10) as shown in FIG. 3.

    [0027] Said polymer-based film layer (10) is made of a polymer, preferably a polyethylene-based polymer.

    [0028] Said metallized surface layer (20) is a metal-based layer obtained by metallization through applying a metal vapor, and preferably aluminum vapor to the polymer-based film layer (10).

    [0029] An embodiment of the invention relates to a thermal insulating shrink film, characterized by functioning as both a standard shrink film in palletization of products and a thermal insulating pallet cover that protects the product against external weather conditions thanks to its metallized reflective surface.

    [0030] The invention aims to provide a reflective surface on a standard shrink film through metallization operation not only to prevent the pallet from coming apart in all fields of application of standard shrink films, but also to maintain the original temperature of the product for a longer time, thereby eliminating the need for additional insulating materials.
