FAQ

Q: How does PP Corrugated Sheet compare to cardboard?

A: PP sheet offers higher moisture resistance, longer service life, and better compressive strength. Unlike cardboard, it does not deform or lose strength when exposed to humidity.

Q: How long is the service life of PP Corrugated Sheet?

A: Depending on usage conditions, it can be reused multiple times, typically far exceeding single-use packaging materials such as cardboard.

Q: Is printing or branding available?

A: Yes. Surface printing and logo customization are available for packaging and industrial branding use.

Q: What type of production equipment is used?

A: We use automated PP extrusion lines designed for continuous sheet production with controlled thickness accuracy.

Q: What is your MOQ?

A: MOQ depends on thickness and specification, but we support flexible trial orders for new wholesale customers.
