What Are The Quality Parameters To Consider Before Purchasing Caps and Closures?

You have manufactured one of the amazing products. But, is that enough for marketing it to millions of customers?

You cannot say that.

You need to pack it nicely and make it possible for customers to get the same product without any tampering. That’s where caps and closures come into the picture. They are like the final step to making any packaging full-proof.

So, next comes the testing part. Whether or not the product is living up to the standards. Therefore, making testing one of the most crucial parts of the entire packaging cycle. It is important to maintain the set guidelines so that the product is able to endure shipping.

Now when we are talking about testing, it does not mean just about checking the quality of jars or bottles. It also includes the quality parameters of caps and closures.

Here are some of the quality parameters that need to be kept in check to ensure the product’s quality and value.

• Colour Testing

We need to make sure that the color of caps and closures is uniform while the manufacturing process. If there is an error in any of the colour beads then the whole batch of caps and closures will be disturbed. Each and every batch should be better colour tested.

• Drop Testing

You must test the caps by drop testing. In this, you use caps with filled bottles of oils and other liquids of different viscosity. Then just simply drop the test by making the bottle upside down. If there is any drop leakage then you need to make the manufacturing process better.

• Cap Fitment To Ensure Leak-proof

This particular test ensures that the cap or closure fits on the top of the container. This ensures that the product is leak-proof. Or else the volume will definitely not the same in the final product as mentioned on the packaging

• Top Load or Compression Testing

It checks the tolerance limits of any cap or closure. This is essential because often when the bottles or jars are shipped. They are stacked together.

It helps to give an idea, how many bottles can be stacked together without pushing much to avoid any mishappening in relation to caps or closures

• Hinge Performance Test For Durability

It examines the threshold force in terms of durability. It’s a measure of breakage depending on the times that a hinge can be opened or closed.

• Flip Top Opening Force

This test measures the force required to open a cap in bottles such as ketchup. If the value is too high, then it implies that cap opening might even break the hinge.

• Cap Removal Force

The standard requirement of any cap or closure state that the opening of any cap must take more than one flip, top opening force.

• Torque Test For Testing Screw Mechanism

It helps to determine the force required to open or close any cap.  Besides these physical parameters, there are several chemical parameters that need to check before choosing any cap or closure for your product.

These include testing for unglazed white material (streak test), parting line, or checking for foreign particles. To ensure the quality of the packaging material.
