The Qbag produced by FPP Packaging Solutions in the United Kingdom is an aluminum foil bag with a polyester window. It was specially designed for BBQ picnic foods and won a gold medal in the "DuPont Packaging Award" food category. It combines the strength of aluminum foil with innovative polyester heat sealing technology. With this polyester window, consumers can see the product inside and tear the polyester off for stirring, seasoning or baking. This package can also be used in the oven to maintain the moisture and texture of meat or vegetables. The first to bring Qbag to the market was the Marks & Spencer supermarket chain, which launched a frozen potato/vanilla/garlic/onion hybrid package in June with a shelf life of 6 days. To make this kind of package, FFP first embossed the 38mm aluminum foil. "This can increase the strength of the material, while avoiding the baked food sticking to the package," said Gary Tee of FPP. Because the inside of the potatoes will continue to "breathe" during the distribution process, the polyester has been microporous to allow part of the oxygen to come in. In addition, anti-fog spraying treatment is also performed on polyester.
