Replacement of refrigerant cans by a filler in the Middle East

2-pieces tinplate can – refrigerant can – OEM printing

Customer Background

The customer’s current packaging solution

Since its establishment, this brand has been using 3-pieces cans for 134a and single-piece aluminum cans for other refrigerants. With the evolution of the market and the higher requirements for refrigerant quality and safety, the 3-pieces cans and aluminum cans are increasingly unable to meet the market demands.

Comparison of the advantages and disadvantages of the three types of metal cans:

Our Suggestion and solution

We suggested our customer to use all our 2-pieces cans to pack various refrigerants because these 2-pieces tinplate cans have the following significant advantages:

1. High pressure resistance and good safety

The strength of the tinplate is naturally better than that of aluminum. When the internal pressure of the aluminum can becomes too high, the aluminum can will burst from the can body. The 2-pieces cans are made by stretching and have no welding line. When the internal pressure is too high, the bottom cover of the 2-pieces cans will deform to release the pressure, unlike aluminum cans and 3-pieces cans which will directly burst, greatly enhancing safety.

2. Beautiful appearance

The body of the 2-pieces cans has good integrity, no welding line or top covers. The painted body has a lustrous appearance. The exquisite printed patterns are far superior to those of 3-pieces cans and aluminum cans.

3. Superiority of tinplate

The can mouths formed by rolling tinplate are smooth and of standard size. They are superior to aluminum cans in adaptability and sealing performance. The texture of tinplate is relatively dense, while aluminum is the opposite. During the long-term storage of refrigerants in aluminum cans, water will penetrate into the cans, causing the moisture content of the refrigerants to exceed the standard. 2-pieces tinplate cans won’t have this problem.

4. Competitive price

Due to the complexity of the manufacturing process, the manufacturing cost of the 2-pieces cans is higher than that of the 3-pieces cans. However, compared to aluminum cans, the price advantage of 2-pieces tinplate cans is obvious, especially in larger cans such as 1L cans. 2-pieces tinplate cans are cheaper than aluminum cans.

The status and Future

After thorough communication and sample testing, the customer and our company established a long-term cooperative relationship. Up to now, many Middle Eastern filling companies have chosen our refrigerant 2-pieces cans and have become high-quality partners.
