About Wholesale Blank Corrugated Plastic Signs
JIANXIN blank corrugated plastic signs are made from Polypropylene(PP) corrugated plastic sheets produced in our own factory. This material is cost-effective, easy to cut and process, and well-suited for large-volume custom sign production.
Based on your printing requirements, we can apply single-sided or double-sided corona treatment to improve ink adhesion and make the signs easier to print after delivery.
In addition to standard sizes, JIANXIN can die-cut corrugated plastic signs according to your required dimensions, drawings, or shape specifications, allowing for a wide range of custom shapes.

Complete Your Signs with H Stakes
JIANXIN also supplies H stakes for corrugated plastic signs. Several standard sizes are available to match different sign applications and installation requirements.
