Food packaging
食品包装
Air and the oxygen that air contains have harmful effects on the quality and durability of fresh food. For this reason many processes need evacuation. The classic vacuum application in this field is vacuum packaging. Before sealing, a vacuum pump evacuates the air out of the packet. Vacuum pumps are used in numerous packaging machines for industrial use, e.g. Chamber machines, Forming machines, Carousel machines and Tray sealing machines.
空气和空气中所含的氧对新鲜食品的质量和保存期有不利的影响。因此，许多过程必须排气。在这个领域，真空技术的传统应用就是真空包装。封装之前，用真空泵抽出包装内的空气。真空泵在很多工业包装机中使用，例如，包装机，成型机，转盘传送机，杯盘封口机。

Forming
成型
For vacuum forming, an additional pump is needed at that part of the machine.
对于真空成型，在机器方面要另加一台泵。

Modified atmosphere packaging (MAP)
气调包装（MAP）
The surrounding pressure exerts a mechanical influence on the product that can greatly alter the external shape. For this reason, the MAP process has been the method of choice in many application areas. In this process, products are packaged in modified atmosphere and the oxygen removed. The product is enclosed in a blister package, placed in the vacuum chamber and evacuated. The modified atmosphere is then injected and the blister package and food are sealed with a protective film. Using this method the food retains its original shape and meats present a suitably red appearance to customers, even after extended storage.
周围的压力对产品产生机械作用，大大改变其外部形状。为此，气调包装（MAP）工艺已成为许多应用领域所选的方法。用这种工艺，产品在调节气体、去除氧气的条件下包装。产品封在泡罩包装里，放置在真空室内抽气。然后调节的气体被注入，泡罩包装和食品用保护膜密封起来。采用这种方法，食品保持其原来的形状，肉类仍然向顾客展现适度的红色外观，即使经过长期保存之后，仍然如此。

PET bottling of beer
PET啤酒瓶装瓶
Beer is more and more commonly filled into PET-bottles (polyethylene terephthalate). A pre-evacuation of PET-bottles is, economically speaking, no longer possible. This might have negative effects on the market for liquid ring vacuum pumps.
啤酒越来越普遍地采用PET瓶（聚对苯二甲酸乙二酯）。从经济角度来说，不再可能对PET瓶预先抽气。这可能对液环真空泵的市场有负面影响。
