Key tips for aluminum jarproduction

In the production of aluminium packaging, attention to detail is crucial. Especially between each link, today we are happy to share with you the places that need attention in the production process of aluminum jar.

Material and ink compatibility

One of the main factors in successful packaging design is to ensure that the ink reliably adheres to the aluminum surface. If we use specialist
Single-component inks designed for plastics may have weak adhesion on aluminum because aluminum surfaces need to be specialized
Doors designed for metal inks, such as two-component metal inks, the characteristics of different materials are different, so as to better wear resistance and prevent problems such as fading and scratches over time.

Surface treatment of aluminum

The implementation of the surface treatment process in the production process must ensure the consistency of ink adhesion. Contaminants on the aluminum surface can also reduce the adhesion of the ink. So we will have workers pretreat the surface with a cleaning solution (such as alcohol) for the removal of dust, oil or other residues. Pretreatment of this step is crucial in improving durability, especially on curved surfaces where achieving uniform ink applications is more challenging.

Optimize the curing process

The curing process is standardized with precise temperature and time Settings to ensure consistent ink quality on aluminum packaging. Proper temperature control and baking time are essential for forming a lasting bond. In our experience, we have found that the optimal baking temperature of 140°C is appropriate and the baking time is 20 minutes. This process helps solidify the ink’s attachment to aluminum, even under challenging conditions such as curved surfaces.

By following these expert tips, we can improve the production efficiency and quality of aluminum packaging, ensuring the delivery of high-quality aluminum packaging products.
