Sandwich, burger, and taco wraps are examples of foods that need to be wrapped in specially designed paper to protect the consumer from unpleasant oil and grease.
Boise spokesperson Denise Tripamer told Food Production Daily that the new Block product line is marked out by the range of weights and oil and grease hold out levels it can provide.
"This means no oil or grease comes through to the consumer and there is no stained look on the outside of the wrap," said Tripamer.
Another distinguishing feature underlined by the spokesperson was the absence of perfluorooctanoic acid (PFOA), which is a chemical that has fallen out of favour with some consumers because of evidence linking it to reproductive problems.
Boise will continue to sell its existing EcoOGR line for products that require low grease hold out but is introducing the Block range for use with products that have both medium and high levels of grease.
Boise Block 5 is the moderate grease hold out option and is best used with foods like sandwiches, hamburgers and taco wraps, while Boise Block 7 is reserved for more greasy applications like hash browns.
Customers also have the option of sustainability attributes including chain of custody certification and the addition of unbleached fibre content.
The papers meet the FDA requirements for direct food contact, and according to Boise offer consistent quality for efficient runnability and an excellent flexographic print surface.
