The selection of an appropriate lid for cans requires taking several factors into consideration, including the product contents, conditions of storage, and convenience for consumers. First to be considered is the pressure which a lid can stand. For example, carbonated beverages require lids able to resist internal pressure. For example, a regular soda can lid can hold up to 90 psi, which is also the reason some manufacturers use double seam lids for additional strength. The Aluminum Association estimates that double seam lids increase structural integrity as much as 30% and make them the de facto standard in high-pressure beverages like sodas and energy drinks.
The next factor is the opening mechanism. For many consumers, convenience is key, and that is why easy-to-open pull-tabs have become a standard feature. A report by Packaging Digest shows that 72% of consumers prefer products with easy-open lids, placing the pull-tab at the top. This is the reason why most beverage cans come with pull-tab lids, which are not only easy to open but also eliminate the possibility of injury or spillage. On the other hand, certain specialty products, such as premium beers, may be fitted with more sophisticated lids, including resealable or screw-on caps, to attract a more specific market.
The material of the lid is another important factor. The material used for can lids is most normally aluminum because of its durability and recyclability. The EPA states that 70% of aluminum cans are recycled, so using an aluminum lid helps to make the complete product green. The next most important aspect is the cost of the lid. The average batch of 100,000 aluminum lids will cost anywhere from $1,000 to $3,000, depending on the design and customization options. Ordering lids in bulk can reduce the per-unit cost by up to 15%, as manufacturers benefit from economies of scale.
Branding is another important consideration when choosing the right lid. Lids can be customized with logos or unique designs to enhance a product’s appeal. As Joe Pine, a packaging expert, once said, “Packaging is the silent salesperson that can command attention and create loyalty.” Custom lids enable brands to capture attention on the store shelves and add to the overall consumer experience. For example, craft beer brands buy custom lids that reinforce their identity to capture attention in a competitive market.
Ultimately, the type of lid will depend on the product type, scale of production, and objectives of branding. Whether it’s a carbonated drink, craft beer, or a non-carbonated beverage, the right lid will keep your product fresh, secure, and appealing to consumers. Note that companies can learn more about lids for cans and explore bulk purchasing or customization options that suit their needs.
