How to Test the Right Packaging with a Sample Kit?

One of the biggest mistakes frequently made in packaging selection is placing a bulk order without testing its suitability for the product's needs. Visually appealing packaging can create serious problems during filling, storage, or use. Therefore, examining sample sets is considered the most critical step in choosing the right packaging . Sample sets should not only be used to "see a sample"; they should be used to understand how the product performs in real-world conditions.

Why is a Sample Kit Important? 

Sample sets offer the opportunity to test not only the dimensions of the packaging but also the material structure, the performance of the locking mechanism, and its compatibility with the product. This process is particularly necessary for brands making their first packaging change or companies launching a new product. A small test conducted before a bulk order can prevent potential returns, product loss, and time costs.

Testing the Product in Sample Packaging 

When conducting tests using sample sets, only the actual product should be used. Evaluations based on empty packaging can lead to misleading results. Here are some important points to consider during this process: 

·          Whether the product fits comfortably inside the packaging. 

·          Whether the opening of the packaging was contaminated during filling. 

·          Packaging shape retention performance 

These tests yield extremely critical results, especially when dealing with powders, granules, or oily products.

Checking Locking and Closing Performance 

Sample sets are ideal for testing the ease of use and robustness of the zip-lock doypack models, especially. The ease of opening and closing the zip should be carefully evaluated, as should its security when closed. If heat sealing is to be performed after filling, this process must be tested on the sample packaging, and the straightness of the seal line checked. Otherwise, it may not be possible to determine whether the packaging provides adequate airtightness.

Should a storage and standby test be performed? 

Absolutely, this should be done. Sample packaging should be tested not only during filling but also during the storage period. The product should be left in the sample packaging for a few days or weeks to evaluate the following points:

·          Is there any loss of shape in the packaging?

·          Is the locking mechanism loosening?

·          Is there any change in the product, such as in smell, moisture, or appearance?

These tests are particularly critical for brands that sell in stores.

Comparing Different Packaging Types 

One of the biggest advantages of sample sets is that they offer the chance to test multiple types of packaging side-by-side. The same product:

· Aluminum ,

• Kraft metallized ,

• Experiment with various doypack options, such as kraft window packs , to find the most suitable one.

It becomes possible to determine this. These comparisons should be evaluated not only from a technical point of view, but also from visual and operational perspectives.

Risks of Ordering Without Using a Sample Set 

The most common problems encountered with orders placed without a sample set are as follows:

·          The product does not exactly match the packaging,

·          Locking or closing problems,

·          Decreased packaging performance during the waiting period.

Changing the packaging after these kinds of problems have arisen is usually too late and can lead to high costs.
