A common quick-service sandwich packaging is composed of a polyethylene layer between two paper layers. Grease resistance is important for packaging products containing fats or oils. Polyethylene and most plastics are generally classified as good grease barriers. However, the polyethylene content makes difficulties in separation, recycling and composting of the materials (12). For foods with extremely short shelf-life such as quick-service restaurant sandwiches, the papers coated with natural biopolymers could meet packing requirements as for the grease barrier. Commercial production of grease resistant, isolated soy protein-coated paper has been tested with air knife type coater. Prior to the test, an optimal compositon of ISP coating had been determined in a laboratory of Korea University. But in the commercial scale test, the composition caused severe curl which made it difficult to operate the coating machine. So, in the laboratory of EugeneScience Co., new compositon caused severe curl during the drying process. Resulting compositon contains increased amount of PEG400 and a new substance, dextrose. With the 1st and 2nd commercial tests, three samples are produced and tested on their grease resistance, tensile strength and elongation. The tensile strength (TS) of the ISP coated paper with 6.74g/㎡ of coating of the new composition is 32.06 MPa (between TS of paper and TS of ISP film). The elongation of the paper is 1.95%. The three sample papers were highly impermeable to grease penetration for the first 2 hrs tested. In a near future it is scheduled to introduce a new regulation to reduce the use of polyethylene coated paper for food packaging. Then ISP-coated paper has enough potential to replace the polyethylene coated paper. The market size will be more than 10 billion won.
