What are folding cartons made of?

* Paperboard: Folding cartons are primarily made of paperboard, a thick and sturdy type of paper that usually consists of multiple layers. Paperboard is produced from various materials, including virgin and recycled fibers, and can be coated or laminated to enhance its properties and appearance.

* Corrugated Fiberboard: When extra strength and protection are required, corrugated fiberboard is employed. It is composed of multiple layers of paperboard, with a fluted or corrugated center layer sandwiched between two flat liners. The corrugated structure adds rigidity and cushioning properties to the carton.

* Plastic: Some folding cartons are made entirely or partially from plastic materials. These include polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET). Plastic cartons offer benefits such as lightweightness, durability, and moisture resistance.

* Other Materials: In addition to paperboard and plastic, folding cartons can be made from various other materials, depending on specific requirements. These include metallized films, foil laminates, and specialty papers.

The selection of material for folding cartons depends on various factors, such as the intended use of the carton, desired properties (e.g., strength, flexibility, moisture resistance), cost considerations, and environmental sustainability goals.
