Description: The invention provides modified packing. The modified packing comprises packing, cationic polyacrylamide, carboxymethyl cellulose and amphoteric polyacrylamide, wherein the cationic polyacrylamide is directly combined on the surfaces of packing particles, the carboxymethyl cellulose is combined on the cationic polyacrylamide, and the amphoteric polyacrylamide is used for coating the packing particles entirely. The invention also provides a preparation method of the modified packing, a papermaking technology adopting the modified packing, and paper made by the technology. According to the papermaking technology, as being firmly combined in the modified packing, the carboxymethyl cellulose is combined on fibers along with the modified packing in a papermaking process or is intercepted by fiber layers along with the modified packing to exist in the paper. Therefore, the dehydration and the operation stability of a paper machine are not affected, and meanwhile, the effect of improving paper strength of the carbox
