Description

Technical Field

[0001] This utility model relates to the field of packaging materials technology, specifically to a reagent paper aluminum sealing film. Background Technology

[0002] Aluminum sealing film for reagents is a packaging material used in the pharmaceutical, chemical, and biological fields. It is mainly made of aluminum foil and paper through coating and lamination processes. It has the characteristics of easy tearing, oxidation resistance, high barrier properties, and heat sealing. In practical applications, reagent products (such as diagnostic reagents, vaccines, suppositories, etc.) have extremely high requirements for the sealing and stability of packaging materials. They not only need to prevent external factors such as moisture, oxygen, and light from damaging the reagents, but also need to meet the requirements of easy opening and sterile protection. Therefore, high-performance aluminum sealing film has become a key material to ensure the quality of reagents.

[0003] However, traditional reagent paper-aluminum sealing films have significant technical and process defects. Due to limitations in synthetic materials and processes, they are prone to damage, poor appearance, and abnormal coating during production, resulting in poor product consistency. Their composite technology and surface coating process are complex, which not only increases production costs but also makes it difficult to meet the needs of large-scale production. These shortcomings directly affect the reliability of reagent packaging and may cause reagents to deteriorate during transportation and storage. They also restrict the promotion and application of this type of sealing film in more fields. Therefore, we propose a reagent paper-aluminum sealing film. Utility Model Content

At the same time, the heat-sealing layer 8 can be heat-sealed into different shapes as needed to achieve the sealing and shaping of the packaging. The polyethylene layer 9 of the middle layer 2 and the solvent-based adhesive 10 form a... The adhesive structure ensures a strong connection with the outer layer 1. The underlying aluminum foil layer 11 and the anti-leakage layer 12 form a sealed structure.
