在食品生产过程中，食品是必须要保障的，那么在食品生产中，食品的输送生产也是一个重要环节。
In the process of food production, food safety must be guaranteed, so in food production, food transportation and production safety is also an important link.
在食品输送中，常用的都是轻型输送带，而轻型输送带中，更常用的就是PVC输送带和PU输送带这两种，PVC输送带和PU输送带都属于工业输送带，但它们的区别在于成分的不同。PVC输送带其胶面材质为聚氯乙烯，而PU输送带其原材料为聚氨酯，符合食品卫生标准可与食品直接接触，色泽适度，无异味。
In food transportation, light conveyor belts are commonly used, and among the light conveyor belts, PVC conveyor belts and Pu conveyor belts are the most commonly used. PVC conveyor belts and Pu conveyor belts belong to industrial conveyor belts, but their difference lies in their composition. The rubber surface of PVC conveyor belt is made of polyvinyl chloride, while the raw material of Pu conveyor belt is polyurethane, which meets the food hygiene standards and can be in direct contact with food, with moderate color and no peculiar smell.
从以往咨询和购买输送带的数据来看，这两种输送带一直都是客户购买更多的产品，而在选择上，很多客户会问这两种输送带哪一种更好，其实不存在这些问题，主要还是看输送的物品以及输送设备。
From the data of previous consultation and purchase of conveyor belts, these two conveyor belts have always been the products most purchased by customers. In terms of selection, many customers will ask which of these two conveyor belts is better. In fact, these problems do not exist. It mainly depends on the transported goods and conveying equipment.

如果运输的是食品，如糖果，面食，肉类，海鲜，烘焙食品等，的是pu输送带
If food is transported, such as candy, pasta, meat, seafood, baked goods, etc., Pu conveyor belt is preferred
因为pu输送带具有耐油、耐腐蚀、耐寒、耐切割等特性。聚氨酯(PU)输送带使用经过特殊处理的高强度人工合成聚氨酯织物作为承载骨架，涂覆层由聚氨酯(PU）树脂制成。不但具有普通输送带抗拉强度高、曲绕性好、轻、薄、韧等特点，而且耐油，卫生，容易清洗。该类输送带完全符合美国FDA卫生标准，耐磨，抗物理老化，是一种经久耐用的输送产品。而聚氨酯（PU）是一种可溶于自然界的材料，被称为绿色原料。聚氯乙烯（PVC）含有对人体有害的物质。因此，如果是涉及到食品工业的行业，从食品的角度出发，选用PU输送带是更好的。
Because Pu conveyor belt has the characteristics of oil resistance, corrosion resistance, cold resistance, cutting resistance and so on. Polyurethane (PU) conveyor belt uses specially treated high-strength synthetic polyurethane fabric as the bearing framework, and the coating layer is made of polyurethane (PU) made of resin. It not only has the characteristics of high tensile strength, good winding, light, thin and tough of ordinary conveyor belt, but also is oil resistant, non-toxic, hygienic and easy to clean. This kind of conveyor belt fully meets the health standards of FDA, is wear-resistant and physical aging resistant, and is a durable conveyor product. Polyurethane (PU) Polyvinyl chloride (PVC) contains substances harmful to human body. Therefore, if it is related to the food industry, it is best to choose Pu conveyor belt from the perspective of food safety.
