Description

Paper buffer protection piece suitable for thin electronic product

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the packaging technique and specifically relates to a buffer protection piece made of paper suitable for slim electronic product packing usefulness.

[ background of the invention ]

With the development of network technology, the growth of electronic commerce is increasingly red; before delivering goods to a freight carrier, an e-commerce carrier needs to properly package the goods in a packaging box, which is generally put into the packaging box, bag, 8230et al (hereinafter, collectively referred to as the packaging box), then cover the cover plate of the packaging box, and then stick and package the cover plate with an adhesive tape; as are other postal services. The general packing box structure is to bend the pre-formed folding lines on the paperboard to form a three-dimensional rectangular packing box, and then to bond and fix the three-dimensional packing box by using the adhesive.

As shown in fig. 1 and fig. 2, the general packaging box structure has a main board a, one side of the main board a is sequentially bendable to form a first side board A1, a second side board A2, a third side board A3 and a fourth side board A4, the other side of the main board a is sequentially bendable to form a fifth side board A5, a sixth side board A6, a seventh side board A7 and an eighth side board A8, the first side board A1 corresponds to the fifth side board A5, the second side board A2 corresponds to the sixth side board A6, the third side board A3 corresponds to the seventh side board A7, the fourth side board A4 corresponds to the eighth side board A8, and a protruding board A9 is formed at one end of the main board a; with the structure, a rectangular packing box with a three-dimensional shape can be formed after bending according to the folding line (as the dotted line shown in fig. 1), and then the protruding board A9 is adhered to the other end of the main board a after the protruding board A9 is coated with the adhesive to fix the packing box with the three-dimensional shape.

In order to avoid the electronic products in the packing box from shaking or being damaged by external impact in the transportation and carrying processes, some electronic products must be arranged in the packing box after being provided with a protective piece before being packed; the protective piece is traditionally made of a Styrofoam material, and provides a good protection effect for electronic products by virtue of the characteristics of light weight and impact resistance of the Styrofoam material. However, since the polystyrene material is disadvantageous in that it is not in compliance with environmental regulations and is bulky, a large warehouse space must be prepared to store the polystyrene foam material as a protective member before the electronic product is packaged.

In order to overcome the problems of environmental pollution and excessive space occupation caused by using the Styrofoam as the protection member, many electronic product protection devices made of paper are provided in the market, but the cost of the known paper buffer material is much more expensive than that of the conventional Styrofoam, and the conventional Styrofoam has the problems of complex structure, difficult assembly, high cost and the like; for example, if the paper cushioning material manufacturer is required to assemble the cushioning material in a three-dimensional shape during production, a large amount of space is occupied during transportation and storage, which is very undesirable for economic efficiency and troublesome for the manufacturer.

In addition, for the package of thin electronic products such as notebook computers, tablet computers, flat televisions 8230, etc., the conventional package buffer material is insufficient in structural protection since good protection is required to prevent the electronic products from being damaged.
