由 caicai8478 During the long journey of international transportation, your goods will experience an unprecedented “extreme challenge”. They will be stacked, shaken, bumped, and even subjected to great pressure. How to ensure that they are safe? The answer is not based on guesswork, but on scientific packaging testing.
Anti-shock and anti-pressure testing is to simulate the dangers in a real logistics environment and “rehearse” the disaster in advance in the laboratory, so as to design a truly reliable packaging solution. This is a key investment in minimizing cargo loss, ensuring customer experience and maintaining brand reputation.
- Why do the packaging test?
avoid” “Experience” trap: experience may be overdue or insufficient. New transportation routes, new product characteristics, and new materials all require scientific verification.
Lower cost: The cost of one-time testing is far lower than the loss of bulk goods due to packaging failure, customer complaints and after-sales costs.
Increase customer trust: Prove that your brand has an extremely responsible attitude towards every aspect of product delivery.
Optimizing packaging design: Through testing, find the weak link of the packaging, achieve “precise protection”, avoid excessive packaging, and save material costs.
- International standard: the common language of the test
The global standard for packaging testing is mainly based on the American Society for Materials and Testing (ASTM). 和国际安全安全电视口(ISTA)官方。 Complying with these standards means that your packaging has been certified as internationally recognized reliability.
ISTA Procedure: According to product weight, transportation route, etc., it is divided into multiple series (如1A, 2A, 3A, 3E, etc.), which is the most widely used standard in the electronics and logistics industries.
ASTM D4169: The same authoritative test standard, specifies different transport security levels (DC1-DC4).
- Core test project: simulation of the real world
- Compression Test
Simulated scene: stacking of goods in the warehouse (usually can be stacked to 2-3米 height), compression of other goods in the container.
Test method: Place the packaging between the two pressure plates of the pressure testing machine, and then apply continuously increasing pressure until the packaging box is deformed or crushed.
Optimization direction: If the cardboard box is crushed, it is necessary to choose corrugated cardboard with higher compressive strength (better ring pressure strength), or to optimize the cardboard box structure (such as increasing the internal partition).
- Vibration Test
Simulated scene: truck, ship, aircraft engine continuous vibration. This is the main cause of wear and tear of packaging products, loose parts, and fatigue of the packaging box structure.
Test method: The packaging is fixed on the vibration table, simulating random vibration of different frequency and duration or regular frequency vibration.
Optimization direction: increase the product stability (if using foam mold plastic suspension), increase the internal filling to prevent the product from moving around in the box.
- Drop test (Drop test)
Simulated scene: Unloader’s slippage, conveyor belt fall, accident during transportation. This is the most direct and cruel test of packaging protection ability.
Test method: According to the weight and size of the product, calculate the drop height (normally, the greater the weight, the lower the height). Let the package fall freely to the impact table surface at different angles and angles.
Optimization direction: This is the ultimate test of the effectiveness of cushioning materials (气泡玻璃,珍珠特, foam, etc.). Damage to the product after the test means that the thickness of the cushioning material needs to be increased or replaced with a material with better cushioning performance.
- Impact test (Impact test)
Simulation scene: collision during emergency braking, railway shunting.
Test method: Use a horizontal impact test machine to impact the package at a certain speed and acceleration.
Optimization direction: Ensure that the outer box has sufficient toughness and will not crack under impact.
四、实战指南：How to implement testing for your product
You don’t need to send it to an expensive third-party laboratory every time, you can follow the principle of “from simple to 繁”:
初级self-testing (suitable for medium-sized enterprises):
Stacking test: Put the goods in a single box on the bottom floor, and stack the goods of the same type with the expected quantity on top. Let it rest for 24-48 hours, and observe whether the bottom layer of the paper box has any obvious deformation.
Simple drop test: In a safe environment, according to the estimated drop height (such as 60cm-90cm), drop the corner, edge, and face of the package to check the condition of the product.
“摇晃” test: 封箱后剧烈摇晃, hear if there is any 毒晃 sound inside. If there is, it means that the internal filling is insufficient.
Professional shipping inspection (suitable for high-value, large-batch products):
Determine test standards: Communicate with your customers or customers, clarify the test standards they require or recommend (such as ISTA 2A).
Choose a laboratory: Look for a third-party packaging testing laboratory with ISTA or ASTM certification.
Provide samples: Provide complete production status packaging samples (including outer box, inner material, product) sent to the laboratory.
Analysis report: According to the detailed report from the laboratory, the cause of the analysis failure, and the improvement of the packaging design, until the test is passed.
- Post-test optimization: looping and iteration
Packaging testing is not a one-time project, but a continuous optimization cycle:
Design → test → evaluate → optimize → retest
Whenever the product is changed, the material is changed, or the shipping route is adjusted, the test should be conducted again.
Conclusion
In the harsh environment of international logistics, “I don’t think there is a problem” is the biggest risk. Anti-shock and anti-pressure testing will transform “feeling” into “data”, and “guess” will be upgraded into “science”.
Investing in packaging testing means that you have invested in a “scientific insurance policy” for the safety of your goods. Not only does it bring a lower loss rate, but it is also a 100% complete guarantee and peace of mind. Let your brand win solid trust in the global market because of a reliable package.
