Study of colorimetric properties of kraft papers
Abstract
This article discusses the production of kraft paper incorporating waste materials from the silk industry and secondary recycled paper (MS- 3A), along with fillers and adhesives, as a means of conserving valuable cotton cellulose. The production process utilized waste from the Margilan “IPAKCHI” joint-stock company’s silk reeling operations. The preparation of the paper samples followed an approved technological regulation and was carried out in the testing laboratory of the “Global Komsco Daewoo” joint venture. The resulting new composite kraft papers were investigated for their colorimetric properties. The standardized indicators for these kraft papers allow for a comprehensive assessment of their behavior during the printing process, and therefore, it is recommended to use them for printing multi- color packaging products.
