As demands for food freshness and pharmaceutical safety continue to rise, cold chain logistics technology is rapidly advancing, leading to the emergence of various new cooling products. Among these, Dry Ice Packs for Shipping are widely used and garner significant attention. Compared to other ice packs available on the market, Dry Ice Packs for Shipping, known for their environmental friendliness, safety, and efficiency, play an increasingly vital role in the transportation of food, pharmaceuticals, and biological products.
What are Dry Ice Packs for Shipping?
Dry Ice Packs for Shipping, also known as water-absorbing ice packs or dry-type ice packs, are typically manufactured using Super Absorbent Polymer (SAP) combined with non-woven fabric or permeable film materials. When immersed in water, the SAP rapidly absorbs a large amount of water, forming a gel substance. Once frozen, it provides stable and long-lasting low temperatures.
Differences Between Dry Ice Packs and Other Ice Packs
The market offers various ice packs, including traditional gel packs and water ice packs. Dry Ice Packs for Shipping possess distinct advantages over these alternatives:
- Superior Temperature Control Stability: Traditional gel packs become very hard when frozen and their cooling performance can degrade quickly. In contrast, Dry Ice Packs for Shipping retain some flexibility after freezing, allowing them to conform more tightly to products and enhance cooling efficiency.
- Lightweight and Space-Saving: Unused Dry Ice Packs for Shipping are lightweight and compact, significantly saving transportation and storage space, whereas traditional ice packs occupy more space even when not in use.
- Enhanced Environmental Safety and Safety: The primary materials in Dry Ice Packs for Shipping are non-toxic SAP and water. Leakage does not cause environmental pollution, whereas dealing with leaks from traditional gel pack materials can be problematic.
Structure and Principle of Dry Ice Packs for Shipping
Dry Ice Packs for Shipping generally consist of three main components:
- Outer Layer: Typically made of PE film or water-permeable non-woven fabric, providing permeability while ensuring strength.
- Super Absorbent Polymer (SAP) Layer: Rapidly absorbs and locks in water to form a stable gel.
- Leak-Proof Composite Film Layer: Provides an additional layer of safety to prevent leaks during transportation.
To use, simply immerse the Dry Ice Pack for Shipping in water for several minutes. The SAP swells to form a gel, which is then frozen for use.
Application Areas of Dry Ice Packs for Shipping
Food Transportation
Dry Ice Packs for Shipping are extensively used in food transportation to provide a stable low-temperature environment for fresh fruits, vegetables, meats, and seafood, effectively extending product shelf life.
Pharmaceutical Transportation
