Abstract

The invention discloses a heat insulating and fresh keeping waterproof paperboard carton. A paperboard comprises the following layer structures: a first layer which is white synthetic paper or synthetic paper printed with patterns and provided with a waterproof layer, a second layer which is boxboard kraft paper or any selected payer, a third layer which is made of polyethylene or other spongy foaming coiled materials, a fourth layer which is single-layer or multi-layer bonded corrugated core paper consisting of corrugated payer, a fifth layer which is made of the polyethylene or other spongy foaming coiled materials, a sixth layer which is the boxboard kraft paper or any selected payer and the seventh layer which is the white synthetic paper or synthetic paper printed with patterns and provided with a waterproof layer. The waterproof made of polypropylene mixed polyethylene composite binding layer is respectively formed between every two layers. The heat insulating and fresh keeping waterproof paperboard carton can be used for solving the technical problem that the traditional paperboard carton does not have the functions of containing liquid, insulating heat and keeping fresh.

Description

technical field [0001] The invention relates to a packing box. Background technique [0002] Traditional cardboard cartons are made of corrugated layers in the middle and cardboard on both sides. This kind of cardboard carton has problems such as not releasing moisture and being unable to keep warm. In order to solve the problem of moisture resistance, there are carton products made of corrugated cardboard interlayered with polypropylene film to replace traditional cardboard cartons. However, this moisture-proof carton cannot meet the needs of liquid storage, heat preservation and freshness preservation. Contents of the invention [0003] The purpose of the present invention is to provide a heat-preserving and fresh-keeping waterproof cardboard carton to solve the technical problem that the traditional cardboard carton does not have the functions of holding liquid, keeping warm and keeping fresh. [0004] In order to realize the above-mentioned purpose of the invention,...
