Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require sealing testing, it is recommended to prioritize confirming the pressure range and accuracy indicators of the testing equipment, such as whether it covers negative or positive pressure environments, and whether the error range meets industry application standards.
  • In industries such as automotive parts or medical devices, sealing testing requires high repeatability of test results, and a testing plan with corresponding stability needs to be selected based on the actual scenario.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure equipment performance and after-sales service reliability.
  • For the sealing test of different media (such as gas or liquid), attention should be paid to equipment compatibility. Some models may require additional sensors or specialized fixtures to meet the testing requirements.

Knowledge Base

Q

How to choose a food packaging sealing tester? What industries is the sealing tester suitable for? Can the sealing tester perform sealing testing on samples after falling? What are the characteristics of a sealing tester? What is the testing principle of the sealing tester? How many technical parameters are there for the sealing tester? What are the standard configurations for a sealing tester?

Q

​    With the improvement of living standards, people's demand for fresh food is growing day by day, and their requirements for food quality and safety are also increasing. As an important means of food preservation and extending shelf life, the sealing performance of fresh food packaging directly affects the quality and safety of food. Therefore, the sealing tester for fresh food packaging has become a key factor in ensuring food safety and quality

Q

The sealing directly affects the quality and safety of the product. If the sealing of plastic soft packaging materials is poor, harmful substances such as oxygen, moisture, or microorganisms from the outside may enter the interior of the packaging, causing the product to become damp, oxidized, contaminated, or deteriorated. This not only lowers the quality of the product, but may also pose potential risks to consumers' health. Secondly, sealing is crucial for extending the shelf life of products
