2. Setup and Preparation
The Aviditi flat poly bags are ready for immediate use upon removal from their packaging. No assembly or special preparation is required.
- Carefully remove the desired number of bags from the pack.
- Inspect each bag for any manufacturing defects or damage before use.
- Ensure the bag opening is clear and free of debris.
3. Operating Instructions
Using the Aviditi flat poly bags involves a simple process of filling and sealing to protect your contents.
3.1. Filling the Bag
- Gently open the bag by separating the two sides at the top.
- Insert the product(s) into the bag. Avoid overfilling to ensure proper sealing and prevent tearing.
- Leave sufficient space at the top for the chosen sealing method.
3.2. Sealing the Bag
Several methods can be used to securely close the poly bags:
- Twist Ties: Gather the top of the bag, twist it tightly, and secure with a twist tie. This method is quick and allows for easy reopening.
- Bag Tape: Fold the top edge of the bag over once or twice, then apply packaging tape firmly across the folded edge to seal. Ensure the tape adheres well to both sides of the bag.
- Impulse Sealer (Heat Sealing): For a permanent and airtight seal, use an impulse sealer. Place the open end of the bag across the sealing bar, press down, and hold for the recommended duration (refer to your impulse sealer's instructions). This creates a strong, tamper-evident seal.
3.3. Measuring Flat Poly Bags
Understanding bag dimensions is crucial for selecting the correct size. For flat poly bags, dimensions always represent the inside measurements.

4. Maintenance
Aviditi flat poly bags require minimal maintenance. To ensure optimal performance and hygiene:
- Store unused bags in their original packaging or a clean, dry environment to prevent dust accumulation.
- Avoid exposing bags to direct sunlight or extreme temperatures, which can affect material integrity over time.
- Ensure hands are clean and dry when handling bags, especially when packaging sensitive items.
5. Troubleshooting
While poly bags are generally straightforward, here are solutions to common issues:
- Bag Tears During Filling:
- Ensure items have no sharp edges that could puncture the bag.
- Avoid overfilling the bag; select a larger size if necessary.
- Handle bags gently during the filling process.
- Seal Not Holding:
- For Tape: Ensure the bag opening is clean and dry. Apply tape firmly and ensure sufficient overlap.
- For Impulse Sealer: Verify the sealer's temperature and dwell time settings are appropriate for 2 Mil polyethylene. Ensure no foreign material is on the sealing bar.
- For Twist Ties: Ensure the twist is tight and the tie is securely wrapped.
- Bags Appear Cloudy or Damaged:
- Check storage conditions; excessive heat or prolonged exposure to sunlight can degrade polyethylene.
- If bags are consistently arriving damaged, inspect the shipping packaging.
