Molded Fiber Cellulose Packaging

What cellulose packaging is, and what it can and cannot do

Molded cellulose - also called molded fiber or molded pulp - is packaging formed from a water-based slurry of cellulose fiber drawn onto a screened tool and dried. The material is the point: cellulose is the structural polymer in wood, and the same chemistry that makes a tree stand up makes a pressed wall stiff without any plastic binder.

The fiber source decides the performance. What we work with, and what each one is good at:

• Virgin bagasse - long, strong fiber and a naturally light colour; the usual choice for food contact and bright retail surfaces.
• Recycled kraft - shorter fiber, darker tone, high crush resistance per unit cost; the workhorse for industrial inserts.
• Wood and bamboo fiber - fine fiber for thin, smooth walls and tight tolerances on small parts.
• Wheat, rice straw and other agricultural residue - seasonal local fiber, often blended to hit a target stiffness.

Two forming processes follow from the fiber choice. Dry pressing pulls and dries the shape, giving a rougher, more economical wall; wet pressing draws and press-dries it, giving a smooth, dense wall that holds tolerance and takes print. Thermoforming adds a heated tool pass for a still smoother, thinner section.

What cellulose does not do is provide a water or grease barrier on its own, so food packs are designed around that limit - raised product ribs, short service windows or an in-line barrier layer. MOQ is 10,000 pieces per design; tooling 7–15 days; production 15–25 days after sample approval. Tell us the application and we will recommend the fiber and process - or see the full range.
