Process, clusters, samples & notices工艺、产区、样品与提示
Main process: calendered PVC (mainstream); a few factories use blown film. Calendered film offers better thickness uniformity for battery applications.主流工艺：压延 PVC（主流），少数工厂用吹膜工艺；压延膜厚度均匀性更适合电池使用。
Factory clusters: Foshan/Dongguan (Guangdong, convenient for export), Lishui/Yiwu (Zhejiang), Suzhou and Chongqing.工厂分布：广东佛山/东莞（外贸出货便利）、浙江丽水/义乌、苏州、重庆。
Sample policy: free samples, freight collect; sample lead time 1–3 days.样品政策：样品免费，客户承担运费；样品交期 1–3 天。
PVC is NOT for food contact. Continuous service above 110 °C shortens service life — stated on listings to prevent claims.PVC 不可用于食品接触；长期持续高于 110℃ 使用会加速老化，详情页标注以规避客诉。
