Plastic cups are made of the same material as sealing film, so the sealing effect is better?
Yes, for example, if your cup is made of PP, then the sealing film is recommended to be made of PP. If it is made of PET, then the sealing film is made of PET. In short, if the sealing film and the container are made of the same material, the sealing effect will be better. If the two materials are different, the sealing effect will be seriously affected or the mouth will not be sealed.
