What advanced technologies do manufacturers of high-barrier aluminum foil bag-in-box with butterfly valve use during the selection and lamination of aluminum foil to ensure that the barrier properties of aluminum foil are optimal?

Selection of aluminum foil materials:
Manufacturers usually choose aluminum foil materials with excellent barrier properties, such as AL (aluminum) materials, which have good barrier properties and are higher than VMPET films, and are usually used for anti-static bags, moisture-proof bags, etc.
Lamination technology:
Lamination technology is one of the core technologies for aluminum foil bag lamination. This technology uses high temperature and high pressure to thoroughly laminate multi-layer materials (such as polyethylene, polypropylene, polyester, nylon, paper, etc.) with aluminum foil materials to form food packaging materials with high strength and high barrier properties.
In this process, each layer of material will be pressed to ensure that the aluminum foil is tightly combined with the multi-layer material, thereby improving the barrier properties of the aluminum foil bag.
Lamination process:
During the lamination process, manufacturers will select the appropriate material combination and hierarchy according to specific product requirements. For example, polyethylene material is used as the outer layer because it has good wear resistance and toughness; while aluminum foil material is used as a barrier layer to prevent the invasion of moisture, oxygen and other bacteria.
During the lamination process, parameters such as temperature, pressure and time are strictly controlled to ensure the best lamination effect.
Quality control:
Manufacturers will establish a strict quality management system to conduct comprehensive testing and control of raw materials, semi-finished products and finished products. For example, the quality and barrier properties of aluminum foil bags are evaluated through tests such as impact resistance, tear resistance, and tensile properties.
Customization service:
Based on customer needs, manufacturers also provide customization services. This includes customizing aluminum foil bags with specific barrier properties for customers based on the specific specifications, size, shape and other requirements of the product.

During the production process, how do suppliers of high barrier aluminum foil bag-in-box with butterfly valve test and monitor the barrier properties of aluminum foil bag-in-box with butterfly valve?

Barrier performance testing methods:
Moisture barrier performance testing: The moisture barrier properties of aluminum foil packaging are accurately determined using methods such as weight method, humidity balance method or conductivity method. These methods are based on the aluminum foil packaging's ability to block moisture under specific conditions to test its waterproof performance.
Oxygen barrier performance testing: The oxygen permeability method or oxygen transmission rate method is used to determine the oxygen barrier properties of aluminum foil packaging. These methods help evaluate the ability of aluminum foil packaging to prevent drug oxidation.
Light barrier performance test: Use ultraviolet spectroscopy, visible spectroscopy or fluorescence spectroscopy to measure the light barrier performance of aluminum foil packaging. These methods can evaluate the ability of aluminum foil packaging to prevent changes in drug photosensitivity.
Microbial barrier performance test: Evaluate the barrier performance of aluminum foil packaging to microorganisms through the total colony count determination method, mold and yeast determination method, etc. This helps to ensure that drugs are free from microbial contamination and maintain their quality and safety.
Barrier performance testing instruments:
Aluminum foil infrared water vapor transmission rate tester: Based on the infrared test principle, it provides a wide range and high-efficiency water vapor transmission rate test for aluminum foil.
Aluminum foil differential pressure gas permeability meter: Based on the differential pressure test principle, it is used to test the gas transmission rate of aluminum foil.
Aluminum foil oxygen transmission rate tester: Uses coulometric oxygen sensor and isobaric test principle to test the oxygen transmission rate of aluminum foil.
Testing requirements:
Accurate and reliable testing methods: The testing methods should be scientifically verified, repeatable and accurate, and comply with relevant standards and regulations.
Advanced and complete testing equipment: The testing equipment should have advanced technology and good performance, be able to meet the requirements of the test, and ensure the reliability and accuracy of the results.
The testing environment meets the requirements: The testing environment should meet the specified temperature, humidity and cleanliness requirements to avoid interference from external factors on the test results.
The professional quality of the testing personnel is high: The testing personnel should have relevant professional knowledge and skills, be familiar with the operation of the testing methods and equipment, and be able to perform the testing work accurately and reliably.
Monitoring measures:
Regular testing: Regularly test the barrier performance of the aluminum foil box with butterfly valve to ensure that it continues to meet the relevant standards and requirements.
Quality control in the production process: During the production process, strict quality control measures are taken to ensure that the barrier performance of the aluminum foil box with butterfly valve is not affected.
Product traceability and records: Establish a product traceability and record system to record and track each batch of products in detail so that problems can be traced and handled in a timely manner.
