When thinking about food and beverage canning, manufacturers are most concerned about how to keep products fresh and safe from oxidation. The role of the can bottom ends in this process is, without doubt, the most important one. We can examine how these work and stop the oxidation of food, and also what factors distinguish the solutions of Worunda in the marketplace.

The Critical Role of Can Bottom Ends in Oxidation Prevention
Oxidation is a major threat to canned food, as it can lead to spoilage, loss of flavor, and nutritional degradation. Bottom ends, along with top ends, form a protective barrier that keeps oxygen out and maintains product integrity. Here’s how:
1. Airtight Sealing: The First Line of Defense
The purpose of the lower end of a food can is the creation of a hermetic sealing with the can body. Worunda’s lower ends are designed to fit the can body in a full range, thus preventing the penetration of any air. This sealed package guarantees:
- Extending Shelf Life: Nonconsumable goods like canned tomato paste or bottled juice, etc., may keep fresh.
- Maintaining Quality: Oxidation can cause discoloration and off-flavors, but a secure seal keeps these issues at bay.
For instance, Worunda’s 153mm tomato paste can bottom ends are accurately and aptly designed to form an airtight and oxygen-free seal, which is ideal for the preservation of the original flavor of tomato products.
2. Material Matters: Choosing Oxidation-Resistant Materials
The material of can bottom ends plays a key role in oxidation prevention. Worunda uses high-quality materials such as:
- Tinplate: Tinplate is also known for its strength and corrosion resistance, which characterizes it as an excellent shelf storage material against oxygen and water vapor.
- Tin-Free Steel (TFS): Used in their 50mm beverage can bottom ends, TFS offers excellent resistance to corrosion, making it perfect for acidic beverages like juices or sodas.
With these materials together with proper coatings, an air-tight barrier is created that does not allow oxygen to penetrate food or drink.
3. Coatings: Adding an Extra Layer of Protection
Worunda’s can bottom ends feature specialized coatings that enhance oxidation resistance:
- Internal Coatings: Options like gold, white, or clear coatings create a non-reactive surface between the metal and the product. For example, their tomato paste can bottom ends use coatings that prevent the acidic tomato from reacting with the metal, thus avoiding oxidation.
- BPA-Free Options: Worunda offers BPA-free coatings, ensuring both safety and oxidation protection for food products.
The 73mm fruit can ends, with their tailored internal coatings, are designed to keep fruits fresh by blocking oxygen and preventing flavor degradation.
