Choosing a Useful, Durable, and Highly Cold-Retention Ice Pack
Selecting an ice pack that is useful, durable, and possesses excellent cold-retention capabilities can provide effective cold therapy and insulation in daily life, medical emergencies, or outdoor activities. Below are key factors and recommendations to consider when choosing an ice pack: 1. Material Selection External Materials: High-Strength Tear-Resistant Materials: Such as polyethylene (PE) combined with polyamide (PA), or PE combined with PA and non-woven fabric for the outer pouch material. These materials possess leak-proof and tear-resistant characteristics, ensuring safety and durability during use. Soft Texture: Choose materials with a soft and comfortable surface, suitable for prolonged skin contact to reduce discomfort. Internal Fillings: Water Gel: Offers superior insulation performance, quick cooling speed, and is environmentally friendly. Ice Crystal Beads: Have high cooling efficiency, suitable for situations requiring rapid cooling. Anhydrous Salt Solution: Provides good stability, strong reusability, and is suitable for repeated use requirements. 2. Absorbency Super Absorbent Polymer (SAP): Ice packs containing SAP can absorb excess moisture during freezing,...
