Problems solved by technology

Now there are pulp molded packaging materials on the market as an environmentally friendly product that replaces polystyrene foamed plastics. Its cushioning effect is mainly determined by the hollow shell structure of pulp molded parts, but it bears heavy and severe shocks. Impact strength is poor
Therefore, pulp molded packaging materials can only be used for the packaging of lighter items, such as the packaging of small electrical products and accessories, referred to as "light packaging"; and cannot be used for the packaging of heavier items, such as large electrical products, Packaging for televisions, computer monitors and washing machines, referred to simply as "heavy-duty packaging", has no suitable substitutes in the world today

Abstract

The present invention relates to the field of packing material and is one composite fiber material with buffering and bearing performance. The composite fiber material consists of tubular coarse fiber of 3-60 mm length and fine fiber of 10-60 mesh fiber powder in the weight ratio of 5-100 to 10 and is compounded with adhesive. The molded packing material of the composite fiber material includes casing layer, solid layer and bottom layer and the solid layer is made of the composite fiber material. The molded packing material is used for packing heavy product. The molded packing material may produced with waste agricultural fiber and thus is low in cost and environment friendly.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to fiber composite materials with cushioning and load-bearing properties, molded packaging materials made of the composite materials and applications thereof. technical background [0002] At present, most of the cushioning packaging materials use polystyrene foamed plastics. Because polystyrene foam plastic is difficult to degrade in the natural environment, it forms "white pollution", and the freon (CFC) used in the foam production process destroys the atmospheric ozone layer, seriously affecting the global environment. The use of Styrofoam has been explicitly restricted or banned worldwide. Now there are pulp molded packaging materials on the market as an environmentally friendly product that replaces polystyrene foamed plastics. Its cushioning effect is mainly determined by the hollow shell structure of pulp molded parts, but it bears heavy a...
