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. Entre estos, ​​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, seguridad, and efficiency, play an increasingly vital role in the transportation of food, productos farmaceuticos, y productos biológicos.

​​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. Una vez congelado, 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. En contraste, ​​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:

1. ​​Outer Layer:​​ Typically made of PE film or water-permeable non-woven fabric, providing permeability while ensuring strength.
2. ​​Super Absorbent Polymer (SAP) Layer:​​ Rapidly absorbs and locks in water to form a stable gel.
3. ​​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, verduras, carnes, and seafood, effectively extending product shelf life.

​​Pharmaceutical Transportation​​

Pharmaceutical cold chains demand strict temperature control. Due to their excellent temperature control performance, ​​Dry Ice Packs for Shipping​​ are widely employed in the logistics transportation of vaccines, biologicals, and blood products.

​​E-commerce and Meal Delivery​​

Suitable for various coolers and insulated bags, ​​Dry Ice Packs for Shipping​​ meet both short and long-distance delivery requirements and are widely used in e-commerce logistics and the meal delivery industry.

​​Advantages of Dry Ice Packs for Shipping​​

​​Safety and Environmental Friendliness​​

Non-toxic and harmless, ​​Dry Ice Packs for Shipping​​ pose no environmental risk if leakage occurs and are simple to dispose of.

​​Convenience and Efficiency​​

Fácil de usar: simply soak and freeze, requiring no complex procedures.

​​Flexibility and Versatility​​

Remain somewhat flexible after freezing, allowing them to conform better to the shape of items and improve cooling effectiveness.
