As people prefer convenience nowadays,the market has developed a variety of convenient products, such as disposable lunch boxes, convenient rice, frozen food, etc. Gradually, the safety of these products is valued. Paper cup craft inspection is also particularly important when people start to pay attention to their raw materials, or whether they produce toxic substances at high temperatures.Today, we will learn about the disposable paper cups first.
Ordinary paper cups are machined from raw paper,made of chemical wood pulp and then glued. The early paper cups were all waxed. On the one hand,this process can avoid the direct contact between the paper cup and the contents,which prolong the life of the glue; on the other hand, increase the thickness of the cup wall. For the paper cup craft inspection, the inspection of the early paper cups is too simple, because the waxed paper cups only allow the consumers to drink cold drinks. Once with the hot drinks , the wax on the inner wall of the paper cups will be melted and the paper cups end their lives ahead of time. The danger is that it will burn the user.
Later,there are coated paper cups, which are generally divided into single-sided PE coated paper cups and double-sided PE coated paper cups. As the name implies, the one-sided PE coating is coated with a smooth PE coating on the inner wall of the paper cup, while the double-sided one is coated with a PE coating inside and outside the paper cup. Since PE (polyethylene) has a higher melting point than wax, it meets customer demands to easily carry hot drinks. During the paper cup craft inspection, it is important to check whether the PE coating is evenly covered to prevent liquid leakage. The inspection of disposable tableware plays an indispensable role in ensuring the safety of customer safe and convenient use of the product. Since disposable tableware is in direct contact with the human body, its safety needs to be tested by the laboratory. In the article of Lab Testing , the CLI helps customers select a specific list of product test items and compare the test price to save costs.
Under the premise that the consumer chooses a qualified and safe paper cup,if it is a waxed paper cup, it can be used to hold cold water. Even if it is hot water, it can be drunk after melting the wax, because the wax here is food grade, but this paper cups may leak water and harm consumers.If choose a PE coated paper cup, both hot and cold water can be used and the first cup of water can be drunk. There is no such thing as saying said to hold the first cup of hot water for a few minutes and pour away, then the harmful substances in the paper cup can be removed. We can think about it,if you can use hot water to remove the harmful substances in the paper cup within a few minutes, then the paper cup manufacturer does not have to look for complicated chemistry methods. They only need to use hot water and consumers don’t need to do it by themselves!
When the paper cup we choose is produced by a qualified manufacturer,it has a safety mark, date of manufacture and material mark,etc.And the paper cup is not used after being opened for a long time, the first cup of water can be drunk. Moreover, before the paper cup leaves the factory, the inspection company will carry out the paper cup craft inspection. According to the different objects in the paper cup, the actual liquid is selected for the simulation test to verify the firmness of the paper cup. Paper cup craft inspection helps buyers to guarantee the quality of paper cups, but for consumers, how to correctly select qualified products is the greatest security.
