PET Packaging Thickness Guide
Choosing the right PET packaging thickness is one of the most important decisions when designing custom plastic packaging boxes.
Different products require different levels of strength, transparency and protection. A PET box that is too thin may deform during shipping, while a box that is too thick can increase packaging costs unnecessarily.
As a custom PET packaging box manufacturer, we help customers select the most suitable thickness based on their product size, weight and packaging requirements.
