What’s the Difference Between Aluminum and Tinplate Peel Open Ends?

In the world of food packaging, Peel Open Ends (POE) are widely used for cans and containers. The two main materials for POE are tinplate et aluminum. While both serve similar purposes, tinplate peel open ends offer clear advantages in terms of strength, performance under pressure, and overall value.

Why Tinplate POE Stands Out

Tinplate POE are produced from steel sheets coated with food-grade tin and lacquer. These ends are well-known for their mechanical strength et pressure resistance, making them suitable for packaging products like condensed milk, baby formula, cooking oil, and more.

With the right steel grade—such as T3BA or T4BA—and suitable thickness, tinplate ends hold up well during filling, sealing, and storage.

Key Benefits of Tinplate POE:

• Stronger structure: More resistant to deformation compared to aluminum, especially during transport or sealing.
• Handles pressure better: Essential for vacuum-sealed products and aerosol items.
• Cost advantages: Less expensive and more stable in pricing than aluminum, especially in bulk orders.
• Customizable coatings: Options like white, gold, or BPANI ensure safety and allow for brand-specific appearance.
• Broad application: Widely used in food, dairy, chemical, and industrial packaging sectors.

What About Aluminum POE?

Aluminum Polyolefin (POE) are lighter and are, for the most part, used for things like packing milk powders or instant foods. Even though there are some conveniences that these materials can offer, their inferior strength and pressure resistance are not an optimum situation for packaging in some cases, especially where vacuum or gas retention is required.

Réflexions finales

Where companies require a reliable, food-safe, and economical peel open end solutions, tinplate POE can offer better all-around performance. With customizable options and a proven track record across industries, tinplate ends are a smart choice for modern packaging needs.
