? 合掌车间 / Seaming Workshop Our Seaming Workshop（合掌车间） is an important part of our shrink label production. 这里主要是把印刷好、分切好的薄膜对齐封边，做成筒状标签。 We use high-speed automatic seaming machines（高速全自动合掌机）, which make the seams smooth, strong, and beautiful — no wrinkles, no glue marks. Each roll of label is checked carefully（严格检测） to make sure the seam is flat, firm, and round. Every label goes through seam strength test（封边强度测试） and shrink test（收缩测试） to ensure perfect quality. ✅ Smooth and strong sealing ✅ Adjustable width for different bottle sizes ✅ 100% quality inspection ✅ Factory direct production Our seaming process makes every shrink label fit perfectly on beverage bottles and look professional on the shelf.
