Market Research - Plastic Cup
Simply put, the commonly used plastic cup materials are PP and PS. PP is resistant to high temperatures and microwaves, so the locks and locks you have used are made of PP. PS is not resistant to high temperatures, so it is often used in cold drink packaging. In the production process, the plastic cup is more sanitary than the paper cup, because the production process of the plastic cup is simple, and the package is immediately packaged after being cooled at a high temperature. There are printing, cutting paper, film, reel, and curling on the paper cup. I don't know how many hands I have to touch.
But then again, plastic cups are ok, but not in China. I was even asked if I could use recycled plastic in a plastic cup. I was despised in my heart, but I could not show it. I told him that the recycled plastic had impurities and the cup made was not beautiful. Recycling materials are only one of them. I believe that few people do this. Because the market is fierce. A transparent plastic cup can be seen at a glance. Is there still invisible? It is an additive. Gypsum powder (milk white cup)? Toughener? antifreeze? Whether it is harmful or not, I don’t know it for the time being. However, it can be confirmed that the plastic cup that China exports to the United States is “food-grade pure PP”. There is no impurity in the eyes of others. If you fail to pass the test, you will be allowed to go home!
In fact, in our daily life, we are in contact with the crisper, packing box, plastic bag, food bag, plastic cup, we must carefully observe, if the product used is transparent and transparent, you can use it safely, because basically it is polypropylene raw material and Polyethylene raw materials are processed at one time. No additives or additives are added during the process. If the lunch boxes that are found to be used during the process are other colors, especially milky white, please do not use them because the masterbatch raw materials are added during the processing. Or toner, a large amount of milky white added filler masterbatch to reduce costs.
