How to Do Material Pre-test Before Placing Your Order

1. Prepare Your Liquid Sample

Send the real liquid you plan to package, not a substitute. Key information to attach with samples:

· Liquid viscosity: low / medium / high viscosity

· Liquid features: foamy, corrosive, contains suspended particles, easy to solidify

· Storage requirement: normal temperature or refrigerated

· Target packaging bag/bottle type and filling volume

If your liquid changes texture under different temperatures, note this detail for our test.

2. Items to Verify During Pre-test

1. Filling precision Check whether the machine can keep consistent filling weight or volume for your liquid, to reduce product waste.

2. Anti-dripping performance Test if liquid leaks at the filling nozzle after filling, which contaminates packaging bags and affects sealing.

3. Foam control For foamy liquids, confirm whether foam causes inaccurate measurement and overflow.

4. Sealing effect See if liquid residue on the sealing area leads to weak seals or leakage after packaging.

5. Material compatibility Confirm machine contact parts will not react chemically with your liquid, especially for acidic or corrosive liquids.

3. What You Will Receive After Our Pre-test

We will record the whole testing video, show the full packaging process and finished packages. We also provide test data and professional suggestions:

· Suitable machine model and filling structure

· Recommended adjustment parameters

· Customization advice if your liquid has special requirements

4. Why Material Pre-test Matters

Liquid properties vary widely. Water, juice, syrup, detergent and essential oil behave totally differently during filling. A machine working well for water may fail for thick or foamy liquid.

Pre-test is a low-cost way to confirm machine suitability. It removes uncertainty before mass production and saves your time and capital.

Conclusion

Material pre-test is an essential step before ordering liquid packaging equipment. By testing with your actual liquid sample, you can confirm machine performance and avoid costly production failures. Contact us to arrange your free liquid material pre-test today.
