Nowadays, disposable paper cups are a necessity in every household. Now many large companies have printed their advertisements on small disposable paper cups, because disposable paper cups have now become a hospitable, even essential, everyday tool in people's daily lives and work. As a new propaganda mode of enterprises, advertising paper cups are used in various enterprises. By printing a variety of designed patterns on paper cups, it can not only bring a good mood to the drinkers, but also play a good publicity for the company and provide potential customers for the company.
Then, paper cups are widely used, how to ensure the quality of advertising paper cups ?
1. Pay attention to whether a large amount of brighteners and other harmful substances are added to the paper cup. The paper cup is in direct contact with the oral cavity, and hygiene is particularly important. The choice of paper cups cannot be based solely on whether the paper cups are white or not. In order to make the cups look whiter, some paper cup manufacturers add a lot of fluorescent brighteners. Once these harmful substances enter the human body, they will become potential carcinogens. Paper cups must not only adopt environmentally friendly and green methods during production, but also pay attention to moisture and sterility during storage.
2. Observe and feel the size and strength of the paper cup. The cup body is limp and not strong, and it is easy to leak. Paper cups with poor cup body stiffness are very soft when pinched, and are prone to severe deformation after pouring water or beverages, which affects the use. When choosing a paper cup, you can gently squeeze the cups on both sides with your hands to roughly know the stiffness of the cup. Also pay attention to the specifications of the paper cups. The small paper cups commonly used in supermarkets for tasting or tasting are usually 2 ounces, and most of them are 7 ounces or 9 ounces used in companies, banks, or business offices. More than 12 ounces of 340ml or more are mostly medium or large paper cups used in coffee milk tea stores.
3.Pay attention to the patterns and patterns on the cup wall, and be careful of ink contamination. Advertising paper cups are mostly stacked together. If they are damp or contaminated, mold will inevitably form, so do not use damp paper cups. In addition, some paper cups are printed with colorful patterns and fonts. When the paper cups are stacked together, the ink on the outside of the paper cup will inevitably affect the inner layer of the paper cup wrapped on the outside, and be careful of ink contamination. Secondly, pay attention to the printing method of paper cups
. Generally, flexo printing is commonly used, which is more environmentally friendly, as well as silk printing and offset printing. However, offset printing inks are not environmentally friendly and are not recommended for drinking paper cup printing.
4. Distinguish between cold cups and hot cups. The advertising paper cups we usually use are generally divided into cold drink cups and hot drink cups. Once "displaced", it may threaten the health of consumers. There is generally a layer of food wax on the surface of the cold cup. This kind of wax is very stable and safe at 0℃-5℃, but as long as the water temperature exceeds 62℃, the wax will melt; while the surface of the hot drink cup is pasted with a special film. Not only has good heat resistance, but it is also non-toxic and harmless when soaked in high-temperature beverages. Be sure to distinguish between them and don't use them indiscriminately. Pay attention to identifying products suitable for hot or cold drinks. Cold drink cups are easy to dewax and should not be filled with hot water. In addition, the shelf life of paper cups is up to 2 years. Therefore, when choosing a custom paper cup, you should choose according to the type of drink and the shelf life of the paper cup's production date.
