Theft: The inherent characteristics of PST make it easy to remove or to gain access to the carton by pushing down on it, without leaving a trace of entry. As a result of its lack of tamper-evidence, theft can be a shipping problem.
Cost-effectiveness: On a per foot basis, plastic PST is relatively inexpensive. However, as a practical matter, many people use several strips of tape to seal their cartons to try to ensure security or to create added strength. Once several strips of tape are added to the equation, the inexpensive feature of PST disappears.
Climatic Conditions: Plastic PST doesn’t perform well in varying environments including cold and hot temperatures, high humidity and dusty environments. These challenging situations make PST lose its seal. Further, dirt can get underneath the plastic tape and the integrity of the seal is compromised.

It is difficult and expensive to print your logo or a message on plastic, PST. Your branding efforts are undermined if you are using several strips of tape to try to secure your carton, for they make your cartons make look sloppy.
