Abstract

The invention discloses a low-emission and low-smoke density natural fiber modified composite packaging box, which comprises a box body and a box cover. The box body and the box cover are made of low-emission and low-smoke density natural fiber modified composite board; Density natural fiber modified composite board is composed of wear-resistant layer and base material from outside to inside, the base material is composed of natural fiber and PVC base material; the box body includes the protrusion I in the middle and the ring edge around the protrusion I Ⅰ; the box cover includes the protrusion II in the middle and the ring edge II around the protrusion II; the cross-sections of the box body ring edge I and the box cover ring edge II are all tapered; when the box cover protrusion II is above the ring edge II When the lid is closed on the box body, the ring edge II of the box cover fits closely on the edge I of the box body; further improvement is: the box body and the box cover are provided with a stacking anti-slip structure; the ring edge II of the box cover There is a handle extending outwards at one corner. The invention can utilize natural fibers on a large scale, has good sealing performance, is convenient to stack, does not slip sideways, and is convenient to use.

Description

technical field [0001] The invention belongs to the field of food containers, and in particular relates to a packing box made of a low emission and low smoke density natural fiber modified composite board. Background technique [0002] The use of low-emission and low-smoke density natural fiber modified composite panels to make packaging boxes can realize the large-scale utilization of natural fibers, which is of great significance to the comprehensive utilization of natural fibers and the reduction of pollution. The existing low-emission and low-smoke density natural fiber modified composite packaging box includes a box body and a box cover, and the box body and box cover are made of low-emission and low-smoke density natural fiber modified composite board; The durable composite board is composed of a wear-resistant layer from the outside to the inside and a base material. The base material is composed of natural fiber and PVC base material; the box body includes the protru...
