• intros：{"brand_intro":"北极熊（POLAR BEAR）是源自德国的冷链装备品牌，2008年进入中国市场，专注于高端商用冷藏箱。品牌以\"德国工艺，零度保鲜\"为口号，采用德国进口的PU（聚氨酯）发泡设备和食品级不锈钢内胆。北极熊的品控标准极为严苛，每只箱子需通过72小时连续保温测试和500次开合耐久测试。其产品广泛应用于高端餐饮、医疗冷链和生鲜电商，在商用领域口碑卓著，被誉为\"冷藏箱中的奔驰\"。","product_intro":"北极熊50L冷藏箱定位商用高端市场，核心卖点是德国进口PU发泡层（厚度40mm）和304不锈钢内胆，保温时长可达72小时以上。箱体配备气压平衡阀，防止长途运输中因气压变化导致密封失效。50L容量可容纳标准生鲜筐或40斤食材。相比尤里卡，北极熊在耐用性和卫生性上更胜一筹，不锈钢内胆易清洁且耐腐蚀。缺点是价格高昂（459元），且重量较大（5.5kg），不适合个人用户。","key_specs":{"容量":"50L，适合商用批量配送","保温时长":"≥72小时（实测环境25℃）","材质":"HDPE外壳+德国PU发泡+304不锈钢内胆","密封设计":"医用级硅胶密封条+不锈钢卡扣","净重":"5.5kg，坚固但较重","适用温度":"-40℃至80℃"}}
