Plastic tray considerations
May 21, 2018

  1. In the process of using pallets for hydraulic vehicles and forklifts, the distance between the outer edge of the fork should be as wide as possible to the outer edge of the fork of the pallet. The depth of the fork should be more than 2/3 of the depth of the entire pallet.

2. In the process of using pallets for hydraulic vehicles and forklifts, uniform speed shall be maintained to advance and retreat up and down, so as to avoid damage to the pallets caused by sudden braking and sudden rotation and causing the goods to collapse.

3. When pallets are placed on shelves, the trays should be kept stable on the shelf beams, and the length of the trays should be more than 50mm above the shelf beam outer diameter. Which type of plastic tray is suitable for use in cold storage or in high-intensity use environment? Polypropylene, which cannot be polypropylene, is not resistant to low temperatures at plus or minus 40°C. If you need shelves in the cold storage, it is best to use double-sided trays. If the goods are not so heavy, you can choose either Tian or Sichuan trays. Another: The use of low temperature environment, practice has proved that modified polypropylene can be fully qualified. Modified polypropylene is a high temperature incomplete polymerization product of polyethylene and polypropylene. He has both the toughness of polypropylene, the low temperature resistance of polyethylene, the stability of its physical properties, and its resistance to wear and tear. Large chemical companies, low-temperature cold storage and other environments generally recommend the use of such materials.

Plastic trays made of low-pressure high-density polyethylene can be used, and plastic trays produced from pure raw materials can withstand temperatures as low as minus 30°C. Extrusion-blow molding high-strength blow-molded trays are generally blow molded using HMWHDPE plastics, which have a weight average molecular weight of about 350,000 to 400,000; this plastic raw material has excellent adaptability to environmental temperatures. Ability to use stably in the environment of -40~40°C. It is the first choice of plastic trays for high-strength use. Due to the high cost of raw materials selected by this high-strength blow-molded tray, the technical difficulty of the processing is high and the use of the product is high. Longevity, up to 5 to 10 years. Although the price will be higher at one purchase, the overall cost of use is indeed lower. When high strength is required, this high-strength blow tray can be selected.
