In bottle packaging, the cap may be small, but it plays a big role in both sealing and how easy it is to open. One key factor is the torque value-the amount of force needed to twist the cap open.
1. Too Tight or Too Loose? Both Are a Problem
If the torque is too high, it's hard to open, especially for seniors or people with a weak grip. If it's too low, the cap might come loose during shipping, causing leaks or spills. That's why getting the right balance is so important.
For example, health supplements are often used by older adults. A cap that's hard to open can lead to frustration or even complaints. A smooth opening experience shows that a brand cares about its users.
2. Torque Testing Helps Get It Right
To make sure caps are easy to open but still seal tightly, we use torque testers. These tools measure how much force it takes to tighten or open a cap. At Mingda, every batch of products goes through torque testing to make sure it meets quality standards.
3. Good Torque = Better Safety During Shipping
During transport, bottles face shaking and bumps. If the cap isn't tight enough, it can loosen and leak. That's why proper torque isn't just about user experience-it's also about keeping the product safe for the customer.
