Product Description

- Commodity name: Composite flat pocket
Cleanroom Vacuum Bags (also known as Dust-free Vacuum Bags) are specialized packaging materials designed specifically for high-cleanliness environments. Combining the moisture-proof and anti-oxidation properties of vacuum packaging with the low-particle and low-outgassing characteristics of dust-free bags, they are primarily used for packaging products that demand extremely high levels of cleanliness.
Below is a detailed introduction to cleanroom vacuum bags:
1. Core Characteristics
- High Cleanliness and Low Particle Emission: These bags are typically manufactured in Class 100 or Class 1000 cleanrooms, with strictly controlled particle counts (e.g., no more than 100 particles per cubic meter). The surface is guaranteed to be free of black spots, dust, and bacteria.
- Extremely Low Outgassing: Made from highly purified resins (such as PE resin) without additives like silicone oil, ammonia compounds, or phthalates, ensuring minimal Non-Volatile Residue (NVR) and ionic contamination.
- Excellent Physical and Protective Properties: They feature high transparency, extremely low oxygen/moisture permeability, high puncture and tear resistance, and superior moisture-proof performance, effectively protecting internal products from oxidation and moisture.
- Anti-static Functionality: Many cleanroom vacuum bags also possess anti-static properties, with surface resistivity typically controlled between $1 0^{8} \sim 1 0^{11} Ω$ $10$ $8$ $\sim$ $10$ $11$ $Ω$ , effectively preventing electrostatic discharge (ESD) damage to precision components.
2. Main Application Areas
- Semiconductors and Microelectronics: Used for packaging precision electronic components such as wafers, ICs, PCBs, optical drives, and hard drives, preventing yield drops caused by particles and static electricity.
- Medical Devices and Pharmaceuticals: Used for packaging sterile medical consumables and precision medical equipment, meeting stringent biological evaluation and sterilization packaging requirements.
- Precision Hardware and Optics: Used for packaging precision mechanical parts, optical lenses, and auto/motorcycle parts that require moisture-proofing, anti-oxidation, and high surface cleanliness.
