An anti-pest film may be provided. The anti-pest film has an upward-facing reflective surface and one or more inner reflective layers overlaying an opaque downward-facing layer. The anti-pest film may include a barrier layer between two inner reflective layers, where sandwiching the barrier layer may be two malaic anhydride layers. The upward-facing reflective surface may be a vacuum metalized layer, and in certain embodiments, the vacuum metalized layer may be embossed for providing a plurality of half ellipsoid indentation for increasing the angles of incidents for reflected sunlight. Additional embodiments may include bookending opaque layers on opposing sides of the vacuum metalized layer.

SAFETY STEEL OR WEAR-RESISTANT STEEL, AND USE

The invention relates to a ballistic steel or wear-resistant steel (1) made up of a multilayer steel materials composite comprising a first layer (1.1) composed of a steel which in the hardened or tempered state has a hardness of >350 HBW and at least one second layer (1.2) which is composed of a steel which is softer compared to the first layer (1.1) and is joined by substance-to-substance bonding to the first layer (1.1), wherein the second layer (1.2) has a hardness which is at least 20% lower than that of the first layer (1.1) in the hardened or tempered state. The invention further relates to a corresponding use of the ballistic steel or wear-resistant steel (1).
