Pallet cover classification

1. Universal pallet cover type: Made of ordinary plastic film material, it can be dustproof, rainproof, moisture-proof, light-blocking, UV-proof and has super toughness, puncture-resistant, tear-resistant, and has good dustproof, rainproof, Moisture-proof, light-shielding and UV-proof, and has good toughness, puncture resistance and tear resistance.

2. Insulation tray cover type: The tray cover is made of multi-layer composite materials with thermal insulation properties. It has good dust-proof, moisture-proof, light-shielding, thermal radiation protection, and ultraviolet protection properties. It is also breathable and impermeable, and can effectively eliminate packaging Internal moisture reduces internal humidity, reduces the risk of product damage and deterioration, and has good thermal insulation properties. It has a good protective effect on the storage and transportation of temperature-sensitive chemical, pharmaceutical, agricultural and sideline products. Mainly used for container insulation, large frozen insulation, seafood insulation, etc.

Pallet cover product principle

The thermal insulation cover designed based on the three elements of heat transfer can reduce the internal temperature of the product to a certain extent, maintain temperature balance, and reduce the adverse effects of temperature difference changes on the product. At the same time, its good barrier properties can reduce the infiltration of water vapor and salt, reducing the product's Risk of moisture and mildew.

There are three elements of heat transfer in pallet covers: heat radiation, heat conduction, and heat convection.

1. The aluminum foil layer on the surface of the thermal insulation tray cover can reflect more than 95% of solar radiation.

2. There is a certain gap between the heat-insulating tray cover and the product, which can reduce heat conduction.

3. Aluminum foil is compounded with multi-layer materials, which has good barrier properties and can reduce the entry of water vapor and heat.
