First of all, customized plastic bags can be used in the packaging of industrial and agricultural products. Due to the problem of product resources and price, there are tens of billions of plastic bags used in the packaging of industrial products in our country every year. With the development and application of flexible plastic bags, many custom-made plastic bags are used in the transportation packaging of industrial and agricultural products by sea or land, and custom-made plastic bags are used in the packaging of these products. For example, the packaging of animal feed, the covering materials of farms, the sunshade, windproof and hail proof shed of crops and other materials are inseparable from the use of custom-made plastic bags.

其次是食品包裝領域需要定制塑料袋，常見如復合包裝袋，真空袋等。比如很多的米粉廠、面粉廠等食品包裝廠家都會采用定做塑料袋，市場上常見的如大米編織袋、面粉編織袋和玉米編織袋等都是使用的定做塑料袋產品。

Secondly, in the field of food packaging, we need to customize plastic bags, such as composite bags, vacuum bags and so on. For example, many rice flour factories, flour mills and other food packaging manufacturers will use custom-made plastic bags. The common products in the market, such as rice woven bags, flour woven bags and corn woven bags, are custom-made plastic bags.

三是旅游運輸業當中也經常定做塑料袋產品。比如旅游市場上的臨時賬篷、遮陽傘、旅行袋子都會使用到定做塑料袋，還有各種用于運輸以及儲藏物品的覆蓋材料都會用到定做塑料袋來取代以前舊的棉織篷布等材料。

Third, in the tourism transportation industry, plastic bags are often customized. For example, the temporary tent, sunshade and travel bag in the tourism market will use custom-made plastic bags, and all kinds of covering materials used for transportation and storage will use custom-made plastic bags to replace the old cotton tarpaulin and other materials.

從我們國家改革開放以來，國家相關工業部門就拓寬了塑料袋的應用領域，這些定做塑料袋都被應用于小水利、電力、公路、鐵路、海港、礦山建筑以及軍事工程的建設當中，很多的定做塑料袋在國家的建設項目當中發揮著舉足輕重的作用。另外國內很多地方的抗洪救災現場也少不了使用定做塑料袋來使用，這些塑料袋可以用于堤壩、河岸和鐵路以及公路等建設應用。

Since China's reform and opening up, the relevant national industrial departments have broadened the application fields of plastic bags. These customized plastic bags are used in the construction of small water conservancy, electric power, highway, railway, seaport, mine construction and military engineering. Many customized plastic bags play an important role in the national key construction projects. In addition, custom-made plastic bags can not be used in flood relief sites in many parts of China. These plastic bags can be used in dam, river bank, railway and highway construction.
