Foshan Weller Moisture Proof Technology Co., Ltd. is one of the most experienced manufacturers and suppliers of oxygen absorber packets in China. If you're going to wholesale high quality oxygen absorber packets, welcome to get free sample and discount information from our factory. We also accept customized orders.

These oxygen absorber packets are compact, safe and highly effective oxygen removal products. Their core function is to actively absorb free oxygen (O₂) within the packaging, thereby creating and maintaining a low-oxygen or even oxygen-free sealed environment.

Oxygen Absorber Packets

Noted: We can custom for specific applications.

Oxygen Absorption Capacity

1. Unit Oxygen Uptake: Each gram of oxygen absorber can absorb ≥100ml of oxygen (at standard atmospheric pressure).

2. Oxygen Absorption Rate: At 25°C, 90% of the rated oxygen capacity can be absorbed within 3-4 hours. Saturation is essentially reached within 24 hours.

3. Limiting Oxygen Concentration: When sealed, these oxygen absorber packets can reduce the oxygen concentration within the container to ≤0.01% (100ppm). This significantly slows oxidative deterioration.

4. Capacity: Common packaging sizes range from 20cc to 4000cc. Customized capacity is available.

5. Oxygen Absorption Rate: The oxygen absorption capacity can reach over three times its own weight.

Packet Design

1. Breathable and Leakproof Structure

We utilize a directional breathable membrane. This material allows for efficient oxygen penetration (air permeability > 5,000 mL/m²/24 hours). It also 100% prevents leakage of iron powder from the contents, preventing contamination.

2. Pressure and Damage Resistance

Compression strength > 5 kg/cm². These oxygen absorber packets can resist crushing and deformation during transport, preventing accidental rupture and failure.

3. Adaptable Packaging

Ultra-thin design (thickness < 1.5 mm). Flexible fit for various packaging gaps. Space utilization < 0.3%.

4. Excellent Safety

Using food-grade packaging material. They prevent secondary contamination.

5. Easy operation. No complicated steps are required.
