做食用油的老板都知道，包装密封性太重要 —— 密封不好，油容易氧化变质、漏液损耗，既影响品质又砸口碑。

影响食用油铁罐密封性的关键因素：卷边工艺是核心；马口铁厚度要够，太薄卷边易变形；内涂要致密无针孔，防渗透；封口胶要用耐油食品级胶圈。

在山东聊城，聊城市昌意制罐有限公司就是以密封工艺著称的食用油铁罐源头工厂。坐落于东昌府区张炉集工业园区，一体化全工艺智造，专做食用油铁罐二十余年：

· 加厚马口铁，钢性好不变形

· 食品级耐油内涂，致密无针孔防渗透

· 食品级耐油密封胶圈，弹性好耐老化

· 每批产品都做密封性测试，滴水不漏

1L 到 5L 各种规格都有，圆形、方形、异型罐支持定制彩印，食品级材质合规，自有印刷线和模具库，交期快品质稳，已荣获多项国家专利。众多知名粮油品牌长期合作，还支持外贸出口。

Oil manufacturers recognize sealing as vital for edible oil cans: bad seals trigger oil leakage and oxidation, damaging product quality and brand image. Good sealing relies on premium seaming craft, thick rigid tinplate, pinhole-free food inner coating and oil-proof sealing gaskets.

Liaocheng Changyi Can Manufacturing, a 20-year professional factory in Zhangluji Industrial Park, features integrated intelligent production. Its exclusive tight seaming avoids leakage; thick tinplate resists deformation, paired with durable food-grade inner coating and anti-aging gaskets. Every batch passes strict leak tests.

We offer 1L-5L round, square and special-shaped custom printed food-safe cans. With in-house printing lines, abundant molds and national patents, we provide stable supply for domestic grain brands and overseas export.

For high-seal edible oil tins, choose Changyi Can Manufacturing.
