Description

Impact-resistant composite packaging cushioning material

technical field

The utility model relates to a packaging material, in particular to an impact-resistant composite packaging buffer material with good buffer performance.

Background technique

Among the packaging materials, plastic packaging materials account for a large proportion.

Plastic cushioning packaging materials mainly include expanded polystyrene (EPS), expanded polyethylene (EPE), expanded ethylene-vinyl acetate copolymer rubber and plastic materials (EVA), expanded polypropylene (EPP) and other foamed plastics and Air cushion plastic film. These materials have good cushioning performance, good moisture resistance and low price, but they cannot be degraded and cause serious "white pollution" to the environment.

The existing honeycomb paperboard as a packaging material has the advantages of good compression resistance, easy cutting, easy bonding, low cost, wider temperature range than foam plastics, no packaging pollution, convenient material acquisition, and mature production technology. But there are also some disadvantages, such as hard surface, poor flexibility, poor resilience, difficult to form a three-dimensional curved surface, poor cushioning performance; poor moisture resistance; poor overload recovery, and cannot directly contact the surface of the contents when packaging high-end products , It is easy to cause relative movement between the contents and the buffer cardboard and damage the surface of the contents.

Utility model content

The purpose of the utility model is to provide a shock-resistant composite packaging buffer material with strong buffer performance, less environmental pollution and good compression resistance.

The purpose of this utility model is achieved by the following technical solutions:

It includes outer surface paper, bottom surface paper, sandwich paper I, sandwich paper II, and honeycomb paper core, and is characterized in that it also has wood-plastic foam material layer I and wood-plastic foam material layer II. The wood-plastic foam material layer I is between the top paper and the core paper I, the wood-plastic foam material layer II is between the bottom surface paper and the core paper II, and the honeycomb layer is between the core paper I and the core paper II. Paper core; wood-plastic foam material layer I, wood-plastic foam material layer II and honeycomb paper core have the same height.

The shape of the honeycomb paper core can be regular hexagon or rhombus.

The wood-plastic foam material can be, but not limited to, wood-plastic foam materials such as polyethylene (PE), polypropylene (PP), polystyrene (PS) or polyvinyl chloride (PVC), and the cell structure is preferably closed. The hole should be 0.5~5mm in diameter.

The outer surface paper and the bottom surface paper can be made of kraft paper, and the sandwich paper I, sandwich paper II and honeycomb paper core can be made of corrugated base paper.

The adhesive used for bonding can be the starch glue used in the manufacture of traditional honeycomb paperboard, which can be glued by a roller.

The outer surface paper and the bottom surface paper may also not need to be provided.

Wood-plastic foam (WPC) is a composite material made of polyethylene, polypropylene, polyvinyl chloride and other thermoplastics and plant fiber powder through extrusion, injection molding, pressing and other molding methods. Thermoplastics can be made of industrial and domestic waste plastics, while plant fiber powder can be processed from wood processing waste, wheat straw, cotton stalks, rice husk powder, etc. The production and use will not emit harmful substances to the surrounding environment. Healthy volatile matter, the material itself can be degraded, and can also be recycled for secondary use. Therefore, it is a green and environmentally friendly composite material.

The anti-compression composite packaging material of the utility model, because the outer layer is a wood-plastic foam material, and there are countless scattered spherical small air bubbles in the foam material, so the cushioning performance is strong, it can resist a large external impact, and can quickly recover from deformation ; It can also be heat-insulated and moisture-proof, and can be used for a long time in a humid environment; in addition, the honeycomb paperboard has good compressive performance and can bear a large plane pressure, so the utility model has the advantages of both traditional honeycomb paperboard and foam materials, and can not only be used as Cushioning packaging liner, shockproof lining for industrial products, especially suitable for packaging and transportation of products in humid environment (such as aquatic products, etc.), and packaging of high-grade commodity contents.
