High-Quality Unlined Paint Tins for Industrial & Chemical Packaging
Finding the right packaging for aggressive solvents, oil-based coatings, and industrial chemicals is a critical challenge for manufacturers. If you use the wrong container, the chemical composition of your product can degrade the interior coating, leading to contamination, leaks, and ruined batches. This is exactly where unlined paint tins become the essential packaging solution.
As a leading industrial packaging manufacturer, SeFluid engineers premium unlined metal tins designed specifically to handle products that would otherwise destroy standard epoxy-lined containers.

What Are Unlined Paint Tins?
Unlined paint tins are empty metal containers manufactured from high-grade plain tinplate without any internal protective coating or epoxy resin lining. The natural, shiny tinplate surface is left exposed on the inside of the can.
While lined cans are perfect for water-based (latex) paints to prevent rust, the protective linings inside those cans will dissolve, wrinkle, or peel when exposed to strong solvents. Unlined metal tins rely on the natural resistance of bare tinplate, making them the safest and most reliable choice for aggressive chemical formulas.
Key Applications for Plain Tinplate Cans
Because they lack a reactive internal barrier, our unlined cans are the industry standard for a wide variety of non-aqueous (water-free) liquids. SeFluid’s plain tinplate cans are widely trusted for packaging:
-
Solvent-Based Paints & Coatings: Enamels, oil-based house paints, and industrial automotive coatings.
-
Wood Finishes: Varnishes, lacquers, stains, and polyurethane.
-
Chất kết dính và chất trám kín: Industrial glues and heavy-duty bonding agents.
-
Chemical Solvents: Thinners, mineral spirits, acetone, and cleaning fluids.
-
Petroleum Products: Lubricants, motor oils, and penetrating oils.
Why Source Your Unlined Metal Tins from SeFluid?
When packaging volatile chemicals or premium oil-based paints, container integrity is non-negotiable. SeFluid leverages advanced manufacturing technology to produce industrial paint containers that meet strict international safety and quality standards.
1. Superior Solvent Resistance
By utilizing premium-grade plain tinplate, our unlined cans offer absolute chemical compatibility with aggressive solvents. You never have to worry about lining degradation contaminating your high-value liquids.
2. Precision Leak-Proof Seals
Volatile chemicals require airtight storage to prevent evaporation and hazardous leaks. SeFluid manufactures our tins with precision-engineered, double-seamed bottoms and tight-fitting lids (including traditional friction-fit and lever-lid designs). This ensures a perfect seal that protects your product during transit and long-term warehouse storage.
3. High Structural Durability
Industrial environments demand robust packaging. Our unlined paint tins provide excellent impact resistance, preventing dents and punctures during rough shipping and handling. The rigid metal structure also makes them easily stackable for optimized palletizing.
4. 100% Recyclable and Sustainable
Metal packaging is one of the most sustainable choices available. SeFluid’s unlined metal tins are 100% infinitely recyclable without any loss of quality, helping your brand meet modern environmental standards and appeal to eco-conscious buyers.
Lined vs. Unlined Metal Cans: Making the Right Choice
Choosing between lined and unlined packaging ultimately depends on the chemical makeup of your product.
- Choose Lined Cans (Epoxy/Gold lining) if your product is water-based. The lining prevents the water from reacting with the steel and causing rust.
- Choose Unlined Paint Tins if your product is solvent-based or oil-based. Solvents will melt the epoxy lining of a standard can, so the bare tinplate of an unlined can is mandatory to maintain product purity.
