The tape used in Chinese supermarkets is mostly pressure sensitive tape, and its composition is mainly oily acrylate. Acrylate adhesives are obtained by free radical polymerization under the action of benzoyl peroxide. Most of the enes involved in the polymerization process are involved in the reaction. As pure polymers, there is no toxicity, but not all enes participate in the polymerization reaction, and the remaining small amount of enes that do not participate in the reaction. Monomers have low toxicity, Long-term human consumption is harmful.

For food-grade tape, the country has not issued relevant standards. The current test indicators still remain in terms of appearance, size, initial viscosity, viscosity, and other indicators. There are no food-related test standards.

In foreign countries, there is modified starch as a adhesive for food tape, this kind of tape is made of brown paper, no harm to the human body. There are two kinds of tape on vegetables. One is that the vegetable manufacturer directly sends the vegetable tape to the supermarket, and the name and phone of the vegetable manufacturer are included. The other is the supermarket to bulk vegetables self-adhesive tape, without any words.
