Introduction to the Nine-Layer Structure and Characteristics of Shanghai Tangke Vacuum Bags

 I. Structure and Characteristics of Shanghai Tangke Nine-Layer Vacuum Bags As a type of packaging material, vacuum bags are widely used in modern society. Among them, nine-layervacuum bags are highly favored for their tight structure and excellent durability. The nine-layer structure from outside to inside is sequentially: PA, TIE, PE, PE, PA, TIE, PA, TIE, PE. Each layer of material has unique moisture-proof, oxygen-proof, and fresh-keeping effects. Its characteristics are as follows: 

1.Moisture-proof Performance: The two PA films of the nine-layer vacuum bag feature high moisture resistance, effectively preventing packaged items from moisture damage and reducing the risk of spoilage. The PE films further enhance this stability with their own moisture-proof properties. 

2.Oxygen-proof Performance: It offers excellent oxygen barrier capability, effectively inhibiting oxidation and spoilage of contents. The composite structure of PE and PA films blocks oxygen penetration, ensuring food freshness

3. Fresh-keeping Effect: The nine-layer design prevents oxidation and decay, preserving food freshness and nutrients. Its key advantage over ordinary fresh-keeping bags is vacuum sealing, which isolates contents from air to avoid deterioration. 

II. Purchase and Use of Shanghai Tangke Vacuum Bags When purchasing nine-layer vacuum bags, the following aspects can be considered: 1. Scope of Application: The suitable items for nine-layer vacuum bags vary among different brands. Select the appropriate one according to your own needs. 2.
