the use of foam board

Food Packaging Foam Board

Foam boards are ideal food packaging materials. The foam board sheet, because of its thermal stability and thermal insulation, has become the senior food packaging alternatives. Density of 0.5-0.7g/cm3, foam board sheet in a thickness of 0.5-1.5mm is the production of high rigidity and good heat-insulating tableware (plate, bowl), beverage cups and the like raw materials; the 0.2-0.5g/cm3 density and thickness 1.0-3.5mm foam board sheets are used for meat, food packaging materials (such as processing into pots, plates, used in the applesauce, lactic acid casein, low acidity food packaging) and bottle gasket. German co-extrusion method, density 0.1-0.5g/cm3, and the thickness of 1-3.5mm foam board sheet. These foam board sheets can be used for food or meat packaging, can also be used for the production of shell products and a variety of utensils (plates, dishes, bowls, boxes, etc.). Monolayer foam board sheet from May 1999 to be applied to all kinds of microwave tableware and security, and more resistant to heat, and started in 1998, it is widely used in the manufacture of food packaging containers.

Building Thermal Insulation Foam Board Material

The foam board sheets have low thermal conductivity and thermal heat insulation properties, so the construction foam board is usually used as advanced insulation material applications. Steam pipe insulation materials begin to use foam board, and as the air conditioning pipe insulation materials are also under study. According to statistics, China's domestic air-conditioner production in 2000 reached 18.26 million units, and the foam board with good heat resistance is used as the air conditioning pipe insulation has a huge market. Foam board insulation materials also can be used as a petrochemical pipelines, water pipe freeze protection insulation kits, as well as hot water pipes, conservatory, tank heat insulating material. Due to the high heat resistance of the foam board, the foreigners widely use it for the heat resistance and meet the requirements of the occasion of the foamed sheet, such as for the 90-120℃ heat carrier cycle battery heat insulating material, the engine room and workshop insulation materials, heating pipe insulation kits. In short, in all a portion of the heat problem exists in the use of foam board, a foam board material can be used.

Cushion Packaging Foam Boards

The most important performance in the cushion packaging requirements is energy absorption. Foam board molded products can be used to withstand high loads and repeated shock protection capability than can be made of polystyrene moldings or foam superior. Foam board can be used for computer, medical instruments, precision instruments, audio-visual materials, cameras, glass, ceramics, arts and crafts, a variety of household appliances such as shockproof cushion packaging, in order to avoid injury and damage suffered during transport. Further, the foamed sheet also has advantages and can be directly recycled, the texture is soft and will not damage the surface of the packaged objects. According to statistics, in 1997 only two color TV and color picture tubes on the use of foam boards of over 20,000 tons.
