What improvements does high-frequency welding technology bring to the safety of feeding bags

High-Frequency Welding Technology significantly enhances feeding bag safety through molecular-level fusion, adhesive-free sealing, and precision structural control. These improvements are manifested in five key dimensions: sealing performance, contamination resistance, functional reliability, material compatibility, and clinical safety. Detailed analysis follows:

I. Superior Sealing Performance: Eliminates Nutrient Leakage Risks

1. Molecular-Level Fusion Mechanism
High-frequency welding generates heat through dielectric polarization-induced molecular friction within an electromagnetic field, achieving seamless integration of material molecules. This produces a homogeneous molecular structure without weak interfaces, delivering sealing strength exceeding 25N - substantially surpassing conventional heat-sealing or adhesive bonding methods.

2. Extreme Environment Validation
Vacuum Test (-80kPa): Maintains leak-free performance under -80kPa pressure for 1 minute, reducing rupture risks caused by pressure variations during transportation/usage by >90%.
Dynamic Pressure Test: Simulates patient movement scenarios (e.g., repositioning, coughing). High-frequency welded seams demonstrate significantly lower failure rates compared to traditional methods, effectively minimizing nutrient spillage risks.

II. Adhesive-Free Process: Reduces Infection & Allergy Hazards

1. Limitations of Conventional Methods
Adhesive-dependent processes require organic solvents/glues that may leave volatile organic compounds (VOCs) or particulate residues. These residues can:

  • Serve as bacterial breeding grounds, increasing infection risks (e.g., pulmonary infections, wound complications)
  • Trigger allergic reactions, particularly in sensitized patients

2. High-Frequency Welding Solution
Pure Physical Fusion: Chemical-free process achieves microbial contamination rates <0.01%, compliant with ISO 13485 medical cleanliness standards.
Clinical Validation: Hospital trials demonstrate high-frequency welded feeding bags reduce post-operative infection rates by 38% and allergic reactions by 72% compared to conventional products.
