Problems solved by technology

The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row with each other and support each other to form a triangular structure, which has good mechanical strength, can withstand certain pressure from the plane, and is full of elasticity and cushioning. Good effect; it can be made into liners or containers of various shapes and sizes according to needs, which is simpler and faster than plastic cushioning materials; it is less affected by temperature, has good shading performance, does not deteriorate under light, and is generally less affected by humidity. But it is not suitable for long-term use in an environment with high humidity, which will affect its strength
[0003] Although corrugated cardboard boxes are recognized as green and environmentally friendly packaging products, they still need to use a lot of wood resources at the cost of

Abstract

The invention discloses a low-gram weight reinforced lightweight corrugated box production process, including drying of corrugated cardboard, cutting of corrugated cardboard, bonding of corrugated cardboard, and molding treatment of corrugated cardboard. Cartons made of reinforced lightweight corrugated paper are made of corrugated base paper with low grammage and high strength < 100 g/m2. The internal interval of the corrugated paper is equivalent to the length of the reinforcing ribs, and the surface of the corrugated paper is coated with a waterproof layer. Glue and corrugated cardboard are firstly dried by the dryer, and then cut and folded under the control of the specified size by the automatic cutting machine. ribs, so that the box made has the characteristics of light weight, high strength and waterproof.

Description

technical field [0001] The invention relates to the technical field of corrugated carton production technology, in particular to a low-gram-weight reinforced lightweight corrugated carton production technology. Background technique [0002] Corrugated cardboard is also called corrugated cardboard. It is made of at least one layer of corrugated paper and a layer of cardboard (also called cardboard), which has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. It is made of raw cardboard similar to yellow cardboard by beating with domestic straw pulp and waste paper, and then machined to make it into a corrugated shape, and then the surface is bonded with boxboard paper with an adhesive such as sodium silicate. The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row with each other and support each other to form a triang...
