What Does a Custom Poly Bag Manufacturer Do?
California Plastix is a custom poly bag manufacturer producing polyethylene bags, poly liners, roll stock film, and specialty packaging solutions for food processors, manufacturers, distributors, co-packers, retail brands, and industrial operations.
Unlike distributors that source products from multiple suppliers, California Plastix manufactures products in-house through custom film extrusion, flexographic printing, and precision bag converting. This allows us to maintain quality control, reliable lead times, and production consistency across recurring packaging programs.
From lay flat bags and gusseted bags to wicket bags, zipper bags, poly liners, and roll stock film, every product is engineered to customer specifications and manufactured at our Pomona, California facility.
