Disclosed are a hot melt tape for hook-and-loop fasteners without sewing which may be adhered at a low temperature and complete hardening of an adhesive resin in a short time and a method for manufacturing a seat padding material for vehicles using the same. The method includes preparing the padding material and a hook-and-loop fabric, preparing a hot melt tape having a hot melt resin layer by coating a surface of a release paper with a reactive hot melt resin having a melting point of 40-80 DEG C before reacting, adhering the hot melt tape to a surface of the padding material by applying heat of a temperature of 30-70 DEG C and pressure thereto, removing the release paper, adhering the hook-and-loop fabric to the exposed hot melt resin layer, and hardening the hot melt resin layer by cooling the padding material and the hook-and-loop fabric to a temperature of 0-20 DEG C. 本申请公开了一种可以在低温下粘附并且在短时间内完成粘附树脂的硬化的用于无缝合粘扣的热熔胶带和利用该热熔胶带的车辆座椅填充材料的制造方法。该方法包括以下步骤：制备填充材料和粘扣织物；制备具有热熔树脂层的热熔胶带，热熔树脂层通过在离型纸的表面上涂覆反应前熔点为40-80℃的反应性
