Application industry of plastic pallets in cold storage
Source: kuda 2025-05-14
In the fields of cold chain logistics and low-temperature warehousing, plastic pallets in cold storage are gradually replacing traditional wooden and metal pallets with their excellent material properties and wide application scenarios, becoming the core tool for ensuring the safety of goods storage and transportation. This article will analyze the core value of plastic pallets in cold storage from two aspects: material advantages and application industries.
1、 Material advantages: low temperature resistance, corrosion resistance, long service life
The performance requirements for pallets in cold storage environments are extremely demanding, requiring long-term tolerance to low temperatures below -25 ℃, high humidity, and frequent cold and hot alternation. The plastic pallets specifically designed for cold storage are perfectly adapted to this demand through unique material formulas and process designs.
High density polyethylene (HDPE) and polypropylene (PP)
The mainstream cold storage trays are mostly made of HDPE or modified PP materials. HDPE has excellent low temperature resistance (up to -40 ℃), and can maintain high toughness even in extremely cold environments. It has strong impact resistance and avoids cracking of trays due to low-temperature embrittlement; PP material exhibits stronger moisture resistance in high humidity environments, and its surface is smooth and easy to clean, making it suitable for scenarios with strict hygiene requirements.
Anti slip design and antibacterial properties
The surface of the pallet is often designed with anti slip patterns or embedded with anti slip pads to ensure stable stacking of goods in damp cold storage; Some food grade materials also have antibacterial properties, inhibit mold growth, and ensure a safe storage environment.
2、 Application industry: covering the core scenarios of the entire cold chain chain
Food processing and refrigeration
Meat, aquatic products, and dairy products: need to be stored in an environment of -18 ℃ to -25 ℃ for a long time. The plastic tray's low temperature resistance and easy cleaning characteristics can avoid cross contamination and comply with HACCP food safety certification.
Quick frozen food: Combined with automated assembly lines, durable plastic trays can withstand frequent temperature fluctuations during storage and retrieval.
Medical cold chain
Vaccines, biologics, and other pharmaceutical products have strict temperature control requirements. The low temperature resistance and anti-static properties of plastic trays ensure drug stability, and the surface is smooth and pore free, making it easy to disinfect and sterilize.
Fresh e-commerce and supermarket delivery
The "last mile" delivery of fresh e-commerce relies on efficient turnover, and lightweight plastic pallets (30% lighter than wooden pallets) can improve loading and unloading efficiency, while moisture resistance prevents cardboard boxes from being damaged by moisture.
Chemical Industry and Cold Chain Logistics
Some chemical raw materials need to be stored at low temperatures, and the anti-corrosion characteristics of plastic pallets can withstand acidic and alkaline environments; In third-party cold chain warehouses, standardized plastic pallet sizes (such as 1200 × 1000mm) facilitate matching with shelves and forklifts, improving space utilization.
The material innovation and industry adaptability of plastic pallets in cold storage make them an indispensable infrastructure in modern cold chain systems. With the expansion of fresh e-commerce and stricter regulation of pharmaceutical cold chain, cost-effective and durable plastic pallets will continue to penetrate more low-temperature scenarios, promoting the industry's development towards efficiency, environmental protection, and intelligence. When choosing a company, it is necessary to combine its own temperature requirements, load strength, and industry standards to match the best materials and structural design, in order to achieve the core goal of cost reduction and efficiency improvement.
