Polyethylene resins are used for making ice bags due to their durability, flexibility, and resistance to water. Additives like colorants, UV stabilizers, antioxidants, slip agents, antistatic agents, impact modifiers, fillers, and slip resistance additives enhance ice bag properties, with their specific combinations tailored to the intended use. Manufacturers carefully select these materials and additives to create strong, flexible, and environmentally-friendly ice bags.
