Aerosol Tin Cans: Why “Old School” Packaging Is Beating Aluminum on Cost & Safety
2026-01-07
When purchasing Spray Cans in bulk, brands often face a series of dilemmas: wanting to reduce costs but worrying about high damage rates during transportation; desiring unique shapes to enhance shelf visibility but fearing failure to pass compliance certifications; and even considering the carbon footprint pressure brought by environmental policies. In fact, aerosol tin cans(tinplate Aerosol Cans) have long provided answers with practical performance—this seemingly "traditional" packaging not only outperforms aluminum cans in core areas like cost and safety, but also accurately addresses brands' real pain points in deep-seated needs such as customization adaptation and policy compliance.
Why can aerosol tin cans become a "tool" for cost control? It's not just about cheap raw materials. According to the latest 2025 industry procurement data, the price of tin-plated steel, the base material of tinplate, is 30% lower than aluminum. More importantly, its processing technology is simpler, with a scrap rate of only 0.8% during mass production, compared to 3% or more for aluminum cans. We at SAILON once served a client producing industrial rust removers. Previously, their comprehensive cost per can (including raw materials, processing, and scrap loss) with aluminum cans was $0.23. After switching to bulk custom aerosol tin cans, the comprehensive cost dropped directly to $0.15. With an annual output of 2 million cans, they save $160,000 a year. What's more noteworthy is that the procurement channel for tinplate is minimally affected by international futures fluctuations. The price locking service we provide for long-term cooperative clients allows them to lock in costs 6 months in advance, which is much more reliable than "temporary price cuts" for brands needing stable budgets.
In terms of safety, the advantages of aerosol tin cans go far beyond just "pressure resistance." Who hasn't heard of troubles like spray cans collapsing when stacked in warehouses or leaking due to bumps during long-distance transportation? Our 2025 laboratory test data shows that high-impact-resistant aerosol tin cans (400ml, 0.2mm thickness) have an impact resistance 1.4 times that of aluminum cans. They can remain intact when dropped from a height of 1.5 meters, while aluminum cans are prone to dents or even leaks when dropped from 1 meter. In terms of pressure resistance, it can withstand internal pressure of up to 1.8MPa. Even when stacked 10 layers high in a 45℃ warehouse, it will not bulge or deform—this is a "peace of mind guarantee" for brands needing large-scale warehousing. More importantly, tinplate itself has stable chemical properties and does not react with acidic or alkaline spray ingredients. Our food-grade aerosol tin cans have passed FDA certification. Many clients producing baking release oil and edible spray sauces have used them for three years without any compliance issues, which is difficult for aluminum cans to achieve in some food categories.
Customization and compliance adaptation are another core reason many brands choose aerosol tin cans. Most aluminum cans can only be made into cylindrical shapes. Wanting square or special-shaped designs to fit product usage scenarios (such as the slim design of car sprays) either requires mold costs as high as 100,000 yuan or simply fails to meet pressure resistance standards. But custom special-shaped aerosol tin cans are much more flexible. Last year, SAILON customized curved aerosol tin cans for an automotive air freshener brand. Not only did they fit the size of car cup holders, but they also added non-slip texture design. After launch, the repurchase rate of the product increased by 27%. Moreover, the mold adjustment cycle for tinplate is short, with samples available in 7-10 days, which allows new products needing to respond quickly to the market to seize a lot of time advantages. In terms of compliance certifications, our REACH-compliant aerosol tin cans can meet the chemical and food-grade packaging requirements of multiple regions including the EU and North America. Clients do not need to replace packaging separately for different markets, saving time and money.
With increasingly strict environmental policies, the advantages of environmentally friendly and recyclable aerosol tin cans have become more and more obvious. Its recycling rate is as high as 98%, and the energy consumed in the recycling process is 50% less than that of aluminum cans. More importantly, the carbon footprint of recycled tinplate is 28% lower than that of aluminum cans. The closed-loop recycling project at our Guangzhou factory recycled 300 tons of waste aerosol tin cans last year. After reprocessing into new cans, carbon emissions were reduced by 180 tons compared to production with new raw materials. For brands exporting to the EU, this means it is easier to pass the carbon border tax audit. After all, consumers are paying more and more attention to "environmentally friendly packaging" now. A low-carbon footprint packaging is itself a plus for the brand.
The table below, compiled from our 2025 actual test data, intuitively compares the performance of aerosol tin cans and aluminum cans in core dimensions:
| Comparison Item | Aerosol Tin Cans (400ml) | Aluminum Cans (400ml) |
|---|---|---|
| Comprehensive Cost per Can | $0.12–$0.15 | $0.18–$0.23 |
| Impact Resistance | Undamaged when dropped from 1.5m | Prone to dents/leaks when dropped from 1m |
| Custom Shape Range | Round, square, curved, special shapes available | Mostly cylindrical; special shapes have high cost/difficult to achieve |
| Recycling Utilization Rate | 98% | 85% |
| Compliance Coverage | FDA, REACH and other multi-region food/chemical certifications | Restricted certifications for some food/chemical categories |
| Carbon Footprint | 28% lower than aluminum cans | Higher carbon emissions |
Frequently Asked Questions (FAQ)
- What is the minimum order quantity for custom aerosol tin cans? We at SAILON have launched a flexible policy for small and medium-sized brands. The minimum order quantity for regular round cans is 5,000 cans, and for special-shaped cans, it is 10,000 cans. For start-up brands, they can also apply for the "small-batch trial production service," with a minimum order of 3,000 cans to start customization, greatly reducing the cost of trial and error.
- Can aerosol tin cans be used for sprays containing corrosive ingredients (such as strong acid cleaners)? Absolutely. We will customize the inner wall coating according to the ingredients in the can. For strong acid and alkali products, we use food-grade epoxy resin coating, which can effectively isolate corrosion. Clients have reported that the inner wall of the can body is still free of rust after 12 months of use, with guaranteed compliance and durability.
- What is the delivery cycle for bulk purchases of aerosol tin cans? The delivery cycle for regular orders (existing molds, no special processes) is 15-20 days. Orders for custom molds require an additional 7-10 days for mold production, and urgent orders can be delivered as fast as 10 days. We have 3 warehousing centers nationwide and can also provide batch delivery services to avoid brand inventory backlogs.
- What is the temperature resistance range of aerosol tin cans, and are there any special storage requirements? Its temperature resistance range is -20℃ to 60℃. Daily storage only needs to avoid direct exposure to sunlight and open flames. Even in outdoor warehouses in northern winters, the can body will not crack. We have a client in Northeast China who stored 200,000 cans outdoors in winter, with a damage rate of only 0.1%, far lower than the 1.8% of aluminum cans.
- Will reprocessing recycled aerosol tin cans affect product quality? Not at all. Our recycling process adopts "high-temperature smelting + precision rolling" technology. The purity of the recycled tinplate is consistent with that of new raw materials. Moreover, each batch of recycled and processed cans will undergo pressure resistance and leak-proof tests before being put into production. The product quality is no different from that of new cans.
In the end, the reason aerosol tin cans can surpass aluminum cans is not because they are "old-fashioned," but because they can solve brands' full-link pain points from procurement, production, transportation to sales. Cost, safety, customization, environmental protection, compliance—these are the problems that plague brands, and tin cans have given the most practical answers. We at SAILON have deep experience in the custom aerosol tin can field, witnessing countless brands reduce costs and improve their reputation by choosing the right packaging. For brands, good packaging is never "eye-catching," but "worry-free to use," and aerosol tin cans are exactly such a reliable "full-scenario adaptation" choice.
