The World-Bio Gel Packs are designed for high puncture resistance, utilizing a 0.35mm PVC-lined nylon envelope. This sturdy construction makes them a good choice for active households where they might be tossed into gym bags or used frequently. The 2-pack set is designed to be used for both heat and cold, though it is specifically noted for its performance in cryogenic applications.
In standard domestic freezers, the gel may develop a slightly "crunchy" texture, which softens quickly as it absorbs a small amount of ambient heat. To maintain the integrity of the seams, it is best to avoid folding the pack while it is completely frozen, as this can create stress points in the plastic lining. When heating, using a damp towel wrap can help distribute the temperature more evenly across the surface.
Functional Details
- Textured nylon surface offers a layer of protection against direct "freezer burn" during the initial minutes of use.
- Large surface area makes it suitable for covering major muscle groups like the quadriceps.
- HF-welded seams provide a strong seal for standard placement.
Because the nylon material is porous, it can absorb odors over time. Storing the packs in a sealed container when they are in the freezer will keep them clean and ready for use. These packs are a practical staple for anyone needing a durable, large-scale cooling option.
For a version specifically designed with an integrated strap for hands-free use on the knee or elbow, the Znöcuetöd Gel Pack with Strap may be more convenient.
