Tips for Using Your Polystyrene Cooler Box

• Before packing, place ice packs or frozen gel packs inside to lower the internal temperature, enhancing the cooler’s efficiency.
• Organize items closely to minimize air gaps, which can accelerate temperature changes. Position heavier or larger items at the bottom and fill empty spaces with additional ice packs.
• Reduce the frequency of opening the cooler to maintain internal temperatures, as each opening allows warm air to enter.
• After each use, clean the cooler with mild soap and water to remove any residues. Ensure it is thoroughly dried before storage to prevent mold or mildew growth.
