Abstract

The invention discloses buffer composite packaging paper and a preparation method thereof. The buffer composite packaging paper is prepared from, by weight, 6-18 parts of mineral fiber, 3-9 parts of a modified foaming agent, 60-90 parts of talcum powder, 10-15 parts of a high molecular polymer, 5-10 parts of a dispersing agent and 10-20 parts of a moisture-proof agent.. The modified foaming agent coats the mineral short fibers, the modified foaming agent prepared from carbonate modified by the titanate coupling agent has a better foaming effect in use, initiated bubbles are smaller and denser, and the buffering and damping effects of the packaging paper are guaranteed.

Description

technical field

[0001] The invention relates to the technical field of wrapping paper, in particular to a cushioning composite wrapping paper and a preparation method thereof. Background technique

[0002] With the extensive application of paper in packaging and other fields, the demand is increasing. In particular, the application of white cardboard in the packaging field includes a large number of white cardboard applications in food packaging such as medicines, health care products, cosmetics, electronic products, handbags, and clothing boxes, resulting in a sharp increase in demand for white cardboard. At present, the rapid development of e-commerce and logistics has further promoted the surge in demand for packaging paper products such as cartons and cartons.

[0003] After retrieval, the Chinese Patent Publication No. CN105482222B discloses a cushioning composite wrapping paper and a preparation method thereof, in which short fibers carry a foaming agent so that the f...
