Before purchasing iron cans for engine oil and lubricants, be sure to pay attention to these key points.

1. Do not mix internal wall coatings; distinguish between food-grade and chemical‑grade systems.
This is the most common pitfall in the procurement process. Edible oils such as olive oil and camellia oil are packaged in steel cans coated with food‑contact‑grade inner linings, whereas motor oils and lubricants are chemical products that require specialized inner coatings resistant to solvents and corrosion. If a can with a food‑grade coating is used directly to store lubricants, prolonged storage can lead to blackening of the inner surface due to oxidation, delamination of the coating, and leakage. Shandong Juwei Can Manufacturing has independently developed a corrosion‑resistant coating system specifically for automotive chemical oils, precisely matching it to the type of oil being filled to mitigate quality risks at the source.
2. The thickness of the tinplate directly determines its durability during transportation.
The thickness of the sheet metal directly affects the can’s resistance to impact and its ability to withstand stacking. Some manufacturers on the market cut costs by using thinner materials—0.23 mm or 0.25 mm—which are prone to crushing and deformation, as well as weld‑seam damage, during long‑distance container transport and multi‑layer stacking. At Shandong Juwei Can Manufacturing, our standard iron cans for oil products uniformly employ tinplate with a 0.28 mm thickness. This robust material stiffness ensures that the can remains resistant to dents and deformation even under high‑temperature maritime shipping and repeated handling, providing superior protection for the contained oil. At the same time, it maintains excellent flatness, preventing distortion of printed designs and balancing both packaging aesthetics and durability. For special large‑capacity sizes, we can also tailor the sheet‑metal specifications to meet your specific requirements.

3. Select suitable standard can formats based on the product’s positioning.
Currently, the lubricant and motor oil market is dominated by conventional canister formats, with each style tailored to specific market needs: Standard straight‑body round cans and straight‑body square cans offer the greatest versatility, a wide range of capacity options, and compatibility with the vast majority of motor oil and lubricant products, while maximizing storage efficiency and container stacking. Bulging‑body round cans feature sleek, full‑bodied lines and high visual recognition, making them ideal for mainstream‑size motor oils. Meanwhile, waisted‑body round cans boast a stylish, design‑forward silhouette, perfect for creating differentiated packaging for mid‑to‑high‑end lubricants, small‑volume fuel additives, and premium care products.
We maintain a large inventory of ready-to-use molds for the aforementioned standard styles, allowing customers to select from our standard can designs, thereby avoiding costly mold‑making expenses and shortening both the sampling and delivery timelines.

4. Confirm the regulatory standards of the target export market.
Regulatory requirements for metal packaging used in automotive chemicals vary across countries, with some regions imposing specific limits on VOCs and heavy metals in coatings. Before placing an order, be sure to confirm the export destination with the manufacturer and ensure that complete documentation is available for both the raw materials and the coating, thereby avoiding customs clearance delays upon arrival at the port.
5. Establish clear printing standards to control batch color variations.
Customers with their own private labels should plan their printing strategy in advance: for large‑area brand colors, Pantone spot colors are recommended to ensure consistent color across all batches; for designs with rich tonal layers and gradient patterns, CMYK four‑color printing is the preferred choice. Shandong Juwei Can Manufacturing boasts a mature steel‑can printing control process that minimizes defects such as color variation, scratches, and missed prints.

6. Confirm the entire set of sealing components in synchronization.
The plastic lid and sealing ring that come with the oil can directly determine its leak‑proof performance. It is recommended to source both the can body and the sealing components from the same manufacturer to prevent size mismatches between parts from different suppliers, which could lead to oil leakage risks.
Shandong Juwei Can Manufacturing simultaneously offers food-grade iron cans for edible oils as well as metal packaging for automotive lubricants and engine oils. All standard oil‑can bodies are crafted from 0.28 mm‑thick tinplate, paired with tailored coating solutions, and support OEM and ODM services for custom printing and sample production. Whether you are a domestic auto‑parts manufacturer or an international importer targeting global markets, we can provide comprehensive packaging‑selection solutions that take into account transportation requirements and end‑market needs, helping you mitigate potential procurement risks.
