What Are the Key Factors Affecting Cold Retention?

As an outdoor cooler bag product, the key function is cold retention and freshness preservation. The main factors affecting this performance include:

• Insulation layer thickness: Different thicknesses of insulation determine cold retention duration (4/6/8/24 hours).
• Leak-proof liner: PEVA / TPU one-piece molded liner to avoid leakage risks.
• Sealed zipper: Leak-proof airtight zipper to reduce cold air loss.
• Outer fabric: Different waterproof ratings to suit different usage scenarios.
• Usage method and climate: The amount of ice used and the external temperature both affect cold retention duration.

Besides Cold Retention, What Else Should Be Considered for Materials?

As a cooler trolley bag for food storage, attention must be paid to using safe materials that can come into direct contact with food. Because there are many outdoor usage scenarios, the product's carrying method, abrasion resistance, and tear resistance are all issues worth considering.

What Usage Scenarios Do Different Insulation Layer Thicknesses Suit?

Under the same material quality and craftsmanship, the more layers, the better the cold retention effect, but the usage scenario should also be distinguished.

• 3-layer insulation structure: Short-term scenarios such as supermarket shopping, half-day picnics, and short trips.
• 5-layer insulation structure: Long-time high-temperature outdoor scenarios such as camping, fishing, food delivery, and long-distance self-driving.

What Trolley Series Combinations Can Outdoor Product Brands Develop Simultaneously to Meet a Richer Product Line?

As outdoor product brands such as catering companies, supermarket retailers, and cross-border e-commerce sellers, you can simultaneously develop combination series of Cooler Trolley Bag with Sports Trolley Bag and Travel Trolley Bag to suit more usage scenarios.
