From January 28 to 29, 2025, Foshan Dekai Metal Packaging Co., Ltd. made a grand appearance at Paris Packaging Week 2025, and demonstrated the company's outstanding strength and innovative technology in the metal packaging industry during the exhibition.

Carrying tinplate aerosol cans on board increases the pressure difference between the internal and external pressures, potentially causing them to expand or even explode. Even high-quality cans cannot fully protect against the risks posed by high-altitude, low-pressure environments.

Safely processed tinplate aerosol cans should be collected separately. For households, they can be placed in recyclable metal waste collection bins. For industrial users, they should be stored in a fire-proof, explosion-proof, and well-ventilated area in accordance with hazardous waste storage standards for centralized recycling.

Each tinplate aerosol can has its own tare weight, or empty can weight. After the can is filled with contents and propellant, its weight increases significantly. With use, the weight gradually decreases. When the weight approaches the empty can tare weight, the contents are nearly depleted.

Step 1: Confirm that the can is completely empty. · Press the nozzle until the last drop is released. · Invert the nozzle to confirm that no gas or liquid is ejected. · If a pressurized propellant (such as butane) is present, handle with caution and avoid open flames. Step 2: Label or perforate the can (if permitted). Step 3: Dispose of the can in a metal recycling bin.

A standard three-piece tinplate aerosol can withstand pressures of 12-18 bar (176-260 psi), meeting the international DOT 2Q (180 psi burst pressure) standard. The reinforced design of the cone and dome directly determines whether the can can withstand the expansion pressures experienced during daily transportation, storage, and even high-temperature environments.

The cone and dome of an aerosol can are metal structural components that connect the can body and the nozzle. · The cone: A tapered structure that transitions from the larger diameter of the can body to the smaller diameter of the dome. · The dome: A slightly arched top structure that secures the valve and ensures stable internal pressure through sealing.

The three-piece aerosol can is the most common aerosol packaging format on the market. It consists of three main components: the can body, the cone (the conical top), and the dome (also known as the bottom). The can body is typically made of tinplate steel and joined by crimping or welding. The cone is attached to the top, and then combined with the dome to form a complete three-piece structure.

Tinplate aerosol can manufacturing process: 1. Raw material preparation: 2. Printing and coating: 3. Stamping: 4. Dome manufacturing: 5. Dimensional standardization: 6. Quality inspection process:

Testing Method: · Place the finished aerosol can in water; · Gradually inflate the can using a dedicated pressurizing device; · Record the pressure at which the dome permanently deforms or bursts. Judgment Criteria: Generally, a pressure of at least 1.2 MPa is required, with specific standards depending on the intended use.
