Why are these tests so important? Let's take a look at the key inspections we perform and what each one means.
1. Size Accuracy Test
We check that the bottle's diameter, height, and wall thickness meet the design specifications. Accurate sizing ensures proper cap fit and compatibility with automated filling lines, reducing sealing issues.
2. Sealing Test
This test is conducted under a 27kPa vacuum to check whether the cap and bottle form a tight seal. It helps prevent leaks during transport, especially important for liquids and powders.
3. Drop Test
We simulate accidental drops from a height of 1.2 meters to see if the bottle can withstand impact without cracking or leaking. This ensures durability during handling and shipping.
4. Torque Test
This test checks how much force is needed to open or close the cap. It ensures the bottle is easy to use but won't loosen during transportation.
5. High & Low Temperature Resistance Test
We expose bottles to alternating high and low temperatures to confirm they won't warp or become brittle in extreme climates. This is crucial for export products or long-distance shipping.
6. Microbiological Test
Especially for bottles that will directly contact food or supplements, we test for cleanliness and microbial content to ensure they meet food-grade hygiene standards.
7. Vibration Test
This test simulates the shaking and bumps that occur during long-distance transport. It helps us verify that the packaging holds up well and stays sealed.
8. Infrared Spectroscopy Test
We analyze the plastic material to confirm it meets safety standards and contains no harmful substances, critical for food-contact applications.
9. Cap-Tightening Force Test
We measure the force required to press or screw on the cap, ensuring it seals properly without being too loose or too tight.
10. Aluminum Foil Seal Test
We check that the aluminum seal is fully intact and secure. A good seal keeps out moisture and air, extending shelf life, especially for powder or supplement products.
Why Do We Take It So Seriously?
For manufacturers, every test adds time and cost. But for us, these tests are part of our commitment to your brand, your product's consistency, and your end user's experience.
Whether your bottles are going to hot, humid Southeast Asia or freezing North America, we want every unit to arrive in the same clean, safe, and reliable condition it left our factory in.
If you have special packaging requirements, we can adjust testing procedures to fit your product. Feel free to contact us for customized solutions.
