The invention discloses an edge-covering-free automatic inflation balloon and a manufacturing method thereof, and relates to the technical field of balloons. The inflation balloon comprises an upper sheet and a lower sheet, each of the upper sheet and the lower sheet comprises an outer PE layer, a printing layer, an aluminum-plated layer, a nylon layer and an inner PE layer, the outer PE layers are located on the outer sides of the printing layers, the printing layers are located on the outer sides of the aluminum-plated layers, the aluminum-plated layers are located on the outer sides of thenylon layers, and the nylon layers are positioned on the outer sides of the inner PE layers. The upper sheet and the lower sheet are formed through hot pressing, and pressing edges are located in a cavity of the upper sheet and a cavity of the lower sheet. After the upper sheet and the lower sheet are formed through hot pressing, the pressing edges are overturned into the cavities of the upper sheet and the lower sheet so that the balloon has a more delicate and smoother outline, is better in attractiveness and hand feeling, and prevents the external pressing edges from scratching the skin ofa human body.
本发明公开了一种无包边自动充气气球及其制作方法,涉及气球技术领域。本发明包括有上片材和下片材两部分,所述上片材和下片材均包括有外PE层、印刷层、渡铝层、尼龙层和内PE层五层,且外PE层位于印刷层外侧,所述印刷层位于渡铝层外侧,所述渡铝层位于尼龙层外侧,所述尼龙层位于内PE层的外侧;所述上片材和下片材通过烫压成型,且压边位于上片材和下片材的空腔内部。本发明通过将上片材和下片材通过烫压成型后将压边翻转进上片材和下片材的空腔内部,使得本气球具有更精致、更平滑的轮廓,且在美观度和手感上更好,避免外部的压边划伤人体皮肤。
