Problems solved by technology

[0002] French fries are an essential match for foreign fast food such as McDonald's and KFC, but because fresh French fries must be eaten within 5 minutes after being freshly fried, otherwise they will absorb water and become soft, lose strength and rigidity, and cannot be dipped If the sauce (ketchup) is applied, the taste will be worse, so the fried French fries are basically eaten
If you choose to take away, the French fries will gradually become soft, unable to be dipped in sauce, and lose their crispy taste and deep-fried aroma; as a result, fresh French fries cannot be delivered for takeaway; in addition, fried French fries are prone to mold (2-3 days), cannot keep fresh

Abstract

The invention relates to a preparation method of a packaging material for preventing fried chips from being softened and mildewed. According to the preparation method, 1799 or 1788 type polyvinyl alcohol PVA water-absorption resin or other resin with a water-absorption function, a food-grade non-woven fabric, nano-grade sodium chloride table salt and room-temperature purified water are selected for later use, and are produced into a compound package modified non-woven fabric for packaging the fried chips through procedures of preparing sol and coating to prepare a bag; the compound package modified non-woven fabric and a KPWT/PA/PE compound film are matched to form an applicable package bag for take-out fried chips; the fried chips can keep a good crispy property within three days.
