Challenges and Limitations of Clamshell Packaging

Here are some of the disadvantages of using clamshell packaging.

• Clamshell packaging can’t be used for liquids. It is only suitable for solid products because of how it is designed and structured and the materials used to make this type of packaging. Liquids are likely to leak through clamshell packaging.

• Clamshell packaging is difficult to recycle and can be complicated, depending on the type of material used. If it’s made of plastic, then it’s harder to recycle and doesn’t biodegrade. However, if clamshell packaging is made of cardboard or compostable packaging, it’s easier to recycle or compost.

Factors to Consider for Clamshell Packaging

Here are some factors to consider for clamshell packaging.

Product Size and Shape

As a business owner using clamshell packaging, it’s important to consider the product size and shape.

You need to be able to select or design clamshell packaging that fits your products and will be easy to close. If your product is too big or has an intricate design, then it might make the use of clamshell packaging difficult.

Material Durability

Think about the type of material that you’d like to use for clamshell packaging for your products.

For example, would you like to use plastic or cardboard for fruit and vegetables? If your business serves hot food, using cardboard packaging would make sense.

Ease of Opening and Closing

Customers find it frustrating if they struggle to open packaging, especially if they have sensory or mobility issues. When selecting or redesigning clamshell packaging, be mindful of this. 

Ensure that the packaging your business uses for its products is easy to open and close. If it’s easy to open, customers will be able to access and use the products quickly. If it’s easy to close, customers will be able to protect, store and preserve the products effectively.

Packaging Design and Aesthetics

Many businesses use clamshell packaging to stand out from the crowd, so ensure that you do the same to catch the eye of your target audience. Switch up the design and boost the aesthetics by implementing your brand’s identity (colors, copy and logos).

Environmental Considerations

Sustainability is top priority, so select clamshell packaging that aligns with this ethos. Using materials that are eco-friendly and compostable will impress customers and ensure that they do their part for the planet.
