What ingredients are used to make paper cups? We usually don’t pay attention to this, so the following article introduces the raw materials of paper cups and how to identify the quality of disposable paper cups. I hope it can help you.

What ingredients are used to make paper cups

First, paper cup summary

1. It is an international regulation to avoid the generation of toxic solvents. The disposable paper cups should not be made of recycled materials, and the additives used for raw materials should comply with the provisions of the executive standards.

2. Paper cups sold in the market are made of food grade wood pulp paper and food grade PE film, but there are also many illegal businesses such as low-quality materials.

Second, the raw materials for making paper cups

1. Generally speaking, it is made of food grade wood pulp paper and food grade PE film.

2. The combination of the two materials can effectively prevent the wood pulp paper from losing its original stiffness and toughness due to contact with water. The heat resistance temperature is within 100 degrees. If the cup body is thinner, the heat resistance is even less than 70 degrees.

Third, how to identify the quality of disposable paper cups

First of all, we should know that low-quality paper cups are generally made of recycled waste paper and polyethylene. Some black heart manufacturers even use industrial paraffin and “PVC” to make paper cups. These paper cups do not meet the relevant national production regulations.

1. We can smell

Open the outer package of the paper cup, smell the smell of the paper cup, and the qualified paper cup should have no odor.

Unqualified paper cups, such as industrial paraffin, are coated with non food grade recycled PE instead of food grade PE, which may have some unstable low molecular components free and release peculiar smell. If hot water is contained, the peculiar smell may be more obvious, which should be treated carefully.

2. We can “pinch”

The national standard requires the stiffness of the cup body and the strength of the cup bottom. The paper cup, which is very soft and flat in a little pinch, may be a jerry built product, which is not easy to use. Using this paper cup to receive hot water is easy to cause burns and other accidental injuries.

3. We can take photos

Fluorescent brighteners are not allowed in paper cups. Because some illegal products are made of recycled paper, and the whiteness is not enough, they will add fluorescent whitening agent as the original pulp paper. Although it has not been proved that the absorption of fluorescent agents will cause harm to human body, fluorescent agents have been listed as one of the potential carcinogenic factors.

If there are fluorescent substances, they will emit blue fluorescence when exposed to ultraviolet light. Consumers can use this principle to use a banknote detector that can emit ultraviolet light for preliminary verification.
