How can I choose the films for different types of container?
The sealing effect is critical when it comes to making decision on films' material choosing. As can be seen in the table below, the ES film is applicable to the sealing on all kinds of commonly seen plastic containers, which sealing effect features the film can be removed from the container after sealed due to the film is sealed by sticking and attaching with heat.
On the other hand, for the sealing of PP / PE film on PP / PE containers, the film and container are melted by heater and merged together, in which the film becomes part of the container and the only way to remove the film is to cut and tear it down.
Regardless of these, for beverage cups' sealing, instead of sealing effect, the COST of different materials' films is the most important point to concern.
