Advantages of Hollow Sheet Insulated Box

Lower Logistics Recycling Costs

01

This tray insulation box is detachable and can be disassembled into six insulation boards stacked together when recycled or not in use, reducing the total volume by half; Whether it is the logistics cost when customers purchase products or the logistics cost when customers retrieve insulated boxes, there is a clear cost reduction.

Simple Cargo Loading and Unloading Process

02

When loading goods, a forklift can be directly used to place the goods with pallets in the bottom tray of the insulation box from any direction, without the need for manual movement of the goods from the existing pallets into the insulation box, and then the insulation board can be clamped and assembled into a complete insulation box; The same applies when unloading goods. Greatly reduces the labor cost of transporting goods.

Unique Ice Box Fixing Bracket

03

By using a special ice box fixing bracket to combine multiple ice boxes into one ice box accessory, existing ice boxes can be fully utilized to meet the "big ice box" requirements of the large box, without considering the mold opening problem of the large ice box involved in the large insulation box, and greatly facilitating the transportation and loading and unloading of the ice box in the insulation box.

Materials Used in Insulated Bags

VIP (Vacuum Insulation Panel)

VIP is a cutting-edge core insulation layer used in insulated bags. It boasts exceptional insulation properties due to its vacuum-sealed, micro-porous silica or fiberglass core. This core material ensures outstanding thermal resistance, keeping contents hot or cold for extended periods.

High-Quality Aluminum Film

VIPs are equipped with high-quality aluminum film on both sides of the insulation core. This aluminum film enhances the bag's durability and prevents heat transfer, ensuring the bag's contents remain at the desired temperature.

Aesthetic Appeal

The aluminum film not only serves a functional purpose but also adds to the bag's aesthetic appeal. Its sleek, reflective surface gives the bag a modern and premium look, making it a popular choice for various applications, including food delivery bags and medical supply transport.

Why VIP Panels Require Oxygen Getter Materials, Hydrogen Getter Materials

Over time, microscopic gases (e.g., oxygen, nitrogen, moisture) can permeate the VIP’s barrier or outgas from internal materials, degrading the vacuum. Even trace amounts of gas increase thermal conductivity, reducing insulation performance by up to 30% and shortening the panel’s lifespan. Getter materials are essential to absorb these residual and permeating gases, ensuring long-term vacuum stability.

How Getter Materials Work in VIP Panels

1. Gas Absorption Mechanism

Getter materials in VIPs operate through chemisorption, where reactive metals/alloys chemically bond with gas molecules:

Target Gases: Primarily oxygen (O₂), nitrogen (N₂), water vapor (H₂O), and hydrogen (H₂).

Activation: Non-evaporable getters (NEGs) like zirconium-vanadium-iron alloys are heated during VIP manufacturing to remove surface oxides, exposing active sites for gas trapping.

2. Integration into VIP Structure

Placement: Getters are embedded within the VIP core or laminated into the barrier film.

Function: Continuously absorb gases throughout the panel’s lifecycle, counteracting permeation from external humidity or internal material outgassing.

3. Types of Getter Materials for VIPs

Zirconium-Based Alloys: High-capacity absorption for O₂ and N₂, ideal for long-term applications (e.g., construction).

Calcium Oxide (CaO): Effective for moisture (H₂O) absorption in low-temperature environments.

Hybrid Getters: Combine multiple materials to target a broad range of gases.

What is the difference between thermal and insulated bags?

The key difference between thermal and insulated bags lies in the materials used and the specific design to maintain temperatures, but both are generally intended to regulate temperature, either keeping items warm or cold.

1. Thermal Bags:

Purpose: Specifically designed to maintain the temperature of food or drinks, typically to keep them warm or hot.

Material: Often made from reflective materials like aluminum foil or Mylar, which help to retain heat. Some thermal bags may also have a layer of insulation, but the primary focus is on the reflective properties to preserve heat.

Usage: Commonly used for hot food delivery (e.g., pizza, takeaway food) or to keep food warm during transport.

Construction: The focus is on heat retention, sometimes with a more lightweight design compared to insulated bag for delivery.

Features: May not always have thick padding but will focus on reflecting heat to maintain warmth.

2. Insulated Bags:

Purpose: Designed to maintain both cold or hot temperatures, often used to keep food or drinks cold, but can also work for warmth.

Material: These bags contain multiple layers, typically including an outer layer (like polyester or nylon), insulating foam, and an inner layer (often lined with materials like vinyl, plastic, or foil).

Usage: Used to keep items cold or hot over longer periods, like grocery shopping, picnics, or food storage during trips.

Construction: Insulated bags generally have thicker padding, focusing on preventing the exchange of heat (both inward and outward).

Features: More versatile and effective at temperature regulation (both cold and warm) compared to thermal bags.

Thermal bags: Designed primarily to keep items warm, using reflective materials to retain heat.

Insulated bags: Provide more comprehensive temperature control for both hot and cold items, with multiple layers for better insulation.
