High-barrier, food-grade certified tinplate lids, aluminum easy-open ends, and specialized cans designed for maximum seaming integrity and extended product shelf life.
Why premier edible oil producers, automotive lubricant brands, and chemical processors are abandoning plastic containers in favor of high-integrity electrolytic tinplate solutions.
Lipids, especially polyunsaturated fatty acids and virgin olive oils, suffer severe chemical degradation when exposed to ambient light. Tinplate containers offer 100% light opacity (0 LUX transmission), eliminating rancidity caused by chlorophyll-catalyzed photo-oxidation and preserving free fatty acid (FFA) equilibrium over multi-year storage cycles.
Unlike HDPE or PET bottles, which suffer from structural micro-porosity permitting oxygen ingress at rates between 0.05 to 0.55 cm³/container/day, prime tinplate delivers an absolute barrier. This zero Oxygen Transmission Rate (OTR) stops lipid oxidation, preserving essential organoleptic properties and extending shelf life up to 36 months.
With strict international legislation such as the European Union's Packaging and Packaging Waste Regulation (PPWR), metal packaging leads the circular economy. Steel and tinplate possess an infinitely recyclable nature with magnetic separation efficiency exceeding 92% across municipal recycling infrastructures globally.
A rigorous engineering audit reveals why global oil exporters are migrating towards fully certified tinplate container systems:
| Performance Metric | Electrolytic Tinplate (ETP) Can | HDPE Plastic Container | PET Bottled Packaging |
|---|---|---|---|
| Oxygen Permeability (OTR) | 0.00 cm³/m²/24h (Absolute) | 18.5 - 45.0 cm³/m²/24h | 3.2 - 8.5 cm³/m²/24h |
| UV & Visible Light Transmission | 0.00% (100% Opacity) | 15% - 40% (Semi-Translucent) | 70% - 90% (High Exposure) |
| Chemical Migration & Leaching | Zero (BPA-NI & Organosol Lining) | Risk of Phthalate / Oligomer leaching | Risk of Antimony / Microplastic drop |
| Stacking Compression Strength | > 8,500 N (High Stacking Force) | ~ 2,200 N (Deformation prone) | ~ 1,800 N (Pallet collapse risk) |
| Recycling Rate & Circularity | > 85% Global Rate (Permanent Metal) | < 25% Downcycled Rate | < 30% Mechanical Recycle |
An authoritative breakdown of prime raw materials, temper designations, double-seaming tolerances, and non-reactive internal lacquers engineered for oil stability.
Our manufacturing utilizes prime grade single-reduced (SR) and double-reduced (DR) electrolytic tinplate sourced directly from premier steel mills (e.g., BAOSTEEL, WISCO). Temper options span from T2.5, T3, T4 to DR8 / TH570, yielding yield strengths between 300 to 570 MPa. Nominal wall gauge ranges from 0.18mm to 0.38mm to provide maximum column crush force.
To withstand aggressive fatty acids, moisture, or chemical solvents, our oil containers feature customized inner lacquer systems. Options include Organosol, Gold Epoxy-Phenolic, and 100% BPA-NI (Bisphenol A Non-Intent) linings. Applied at strict film weights (6.0 to 12.0 g/m²), these coatings undergo 200°C thermal curing to ensure zero pores and complete chemical inertness.
Can bodies are formed using SOUDRONIC automated high-frequency electric resistance seam welding. The weld seam is protected via a continuous nitrogen-purged internal and external powder or liquid stripe coating. Double-seaming parameters (Body Hook 1.1-1.4mm, End Hook 1.1-1.4mm, Overlap > 55%) undergo real-time optical video micrometer checks to guarantee zero leak rates under internal pressures exceeding 2.5 bar.
Adapting container geometry, closure spouts, and internal lacquers to match exact regional market preferences, filling line equipment, and liquid viscosities.

Clear, authoritative engineering answers to common inquiries from procurement directors, packaging engineers, and plant managers.
Tinplate provides an absolute barrier against light transmission (0 LUX) and atmospheric oxygen (Oxygen Transmission Rate = 0.00 cm³/m²/24h). Light and oxygen are the two primary drivers of lipid auto-oxidation and photo-oxidation. By eliminating UV/visible light exposure and oxygen ingress, our tin cans maintain the initial Peroxide Value (PV) and Free Fatty Acid (FFA) parameters of extra virgin olive oils and specialty vegetable oils over a shelf life of up to 36 months.
For organic edible oils with elevated free fatty acids or flavored oils containing aggressive essential extracts, we recommend our specialized Organosol or BPA-NI (Bisphenol A Non-Intent) internal lacquers applied at 8.0–12.0 g/m² dry weight. For industrial oils, synthetic engine lubricants, and solvent thinners, we specify high-density Epoxy-Phenolic linings cured at 200°C, providing exceptional chemical resistance against swelling, blistering, and chemical peeling.
Yes. We supply standard ISO neck openings (such as 24mm, 32mm, 42mm, and 57mm) compatible with automated capping and inserting machinery (e.g., BERICAP-compatible press-fit or screw pourers). Our engineering team provides detailed CAD drawings of the container top plate, neck height, and curl dimensions to ensure seamless synchronization with your high-speed filling line machinery.
For plain unprinted standard size containers, MOQs start as low as 5,000 units. For custom lithographic offset CMYK + spot varnish printed containers, standard MOQs range between 10,000 to 30,000 units depending on the container volume (e.g., 250ml vs. 5L). We also offer high-definition digital UV printing options for smaller trial batches and promotional seasonal runs.
All containers are palletized on heat-treated ISPM-15 compliant wooden or plastic pallets, separated by heavy-duty corrugated board layer pads, corner-protected with high-density V-boards, and tightly wrapped in thick stretch hood film. In addition, desiccants are placed inside every shipping container to control moisture dew point and eliminate 'container rain' rust risks during long sea voyages.
Every production batch undergoes strict quality control checks including: 100% online automated pinhole helium/air leak testing, double seam cross-section optical micrometer teardown analysis, enamel rater electrical porosity tests on lacquers, 1.2m drop impact tests, and vertical compression stack force verification. Batch-numbered Certificate of Analysis (COA) documents accompany every sea container.
