PP Hollow Sheet Cold Chain Logistics Packaging Box

Juntai Packaging’s PP Hollow Sheet Cold Chain Logistics Packaging Box are manufactured from polypropylene (PP) and are specifically designed as reusable, insulated packaging vessels for cold chain logistics.

Representing an upgraded alternative to traditional cardboard and Styrofoam boxes, these containers feature three core attributes—low-temperature resistance, water and moisture resistance, and long-lasting freshness preservation—and are widely utilized across various cold chain transport scenarios, including fresh produce, pharmaceuticals, and food products.

Key Performance Advantages

1. Excellent Low-Temperature Resistance

Capable of withstanding temperatures as low as -30°C and as high as 140°C; PP Hollow Sheet Cold Chain Logistics Packaging Box resists embrittlement and deformation under extreme thermal conditions, making it ideally suited for multi-temperature zone cold chain transport—including frozen, refrigerated, and ambient environments.

2. Waterproof and Moisture-Resistant

The hollow corrugated structure effectively blocks moisture penetration, preventing condensation from damaging goods during cold chain transport.

By extending the shelf life of fresh produce, it serves as an upgraded alternative to traditional cardboard boxes.

3. Sturdy and Durable, Reusable

Boasting high compressive strength, it can be reused over 100 times; this reduces overall packaging costs by more than 30% compared to disposable cardboard boxes and supports recycling and reuse.

4. Highly Customizable

Supports customization of dimensions, colors, and printing, enabling adaptation to the packaging requirements of various product categories.

Core Protective Functions

1. Thermal Insulation: Effectively isolates external temperature fluctuations and maintains a low-temperature internal environment (e.g., 0–4°C or -18°C), preventing product spoilage.

2. Moisture-proof and Waterproof: PP Hollow Sheet Cold Chain Logistics Packaging Box prevents moisture penetration that could lead to dampness, spoilage, or packaging damage—particularly suitable for highly moisture-sensitive categories such as seafood, fruits, and vegetables.

3. Physical Protection: Resists mechanical damage, such as impacts, compression, and vibration, during transit, ensuring product integrity.

4. Low-Temperature Resistance: The material must maintain structural stability under extreme low-temperature conditions ranging from -35°C to 0°C—a requirement that standard packaging struggles to meet.

Application Scenarios

Safety and Compliance Functions

1. Health and Safety: Packaging that comes into direct contact with food or pharmaceuticals must comply with food- and pharmaceutical-grade safety standards.

2. Low-Temperature Resistance: Maintains structural stability in low-temperature environments, such as cold storage facilities and refrigerated vehicles, without becoming brittle or deforming.

3. Epidemic Prevention Safety: Particularly during special periods, such as during an epidemic, outer packaging must prevent the transmission of contamination.
