Types of paper used for packaging in the food industry

Paper and paperboards are commonly used in corrugated boxes, milk cartons, folding cartons, bags and sacks, and wrapping paper. Tissue paper, paper plates, and cups are other examples.

There are different grades of paper used in the food packaging industry.

Parchment/Baking Paper – Made from the acid-treated pulp, the acid modifies the cellulose to make it smoother and impervious to water and oil, to add some wet strength. It is not a good barrier to air and moisture, is not heat sealable, and is used to pack fats, such as butter and lard.

Greaseproof Paper – Greaseproof paper is used to wrap snack foods, cookies, candy bars, and other oily foods, a use that is being replaced by plastic films.

Kraft paper – kraft paper is available in several forms: natural brown, unbleached, heavy-duty, and bleached white. Natural kraft is the strongest of all paper and is commonly used for bags and wrapping. It is also used to pack flour, sugar, and dried fruits and vegetables.
