Problems solved by technology

In contrast, corrugated paper is heavy and has a certain degree of hardness, lack of flexibility, and is not easy to bend, so it is not suitable for packaging some thin items
[0004] However, the above-mentioned envelope bags sandwiched with plastic bubble layers are still not fully in line with the development trend of environmental protection.

[0049] refer to Figure 1 to Figure 4 As shown, the embodiment of the present invention provides a sandwich type cushioning packaging material 100, which includes a supporting cushioning layer 10S (refer to figure 2 and image 3 ) and an outer layer 20. The outer layer 20 is pasted on one side of the supporting buffer layer 10S. In this embodiment, the supporting buffer layer 10S and the outer layer 20 can be made of kraft paper, which can meet the trend of environmental protection. But the present invention is not limited thereto, and any planar material that can be bonded can be made.

[0050] The method for manufacturing sandwich type cushioning packaging material of the present invention comprises the following steps: as figure 1As shown, a planar support layer 10 is provided, and a plurality of cutting lines 11 are formed on the planar support layer 10 . A rib 12 is formed between two adjacent cutting lines 11, each of the cutting lines 11 has a plurality of incisio...

[0061] Such as Figure 5 As shown, one of the outer layers 20, 20' is pasted on both sides of the supporting cushioning layer 10S to form a sandwich cushioning packaging material 200. The upper outer surface layer 20 is pasted on one side of the supporting buffer layer 10S, that is, on the plurality of first side convex portions V1; the lower outer layer 20' is pasted on the other side of the supporting buffer layer 10S, that is, Paste on multiple second lateral protrusions V2. In this embodiment, by sticking the outer layers 20, 20' to the first side convex portion V1 and the second side convex portion V2 of the supporting buffer layer 10S, the nest unit 110S can be shaped, and the nest unit 110S is fixed and inclined. It is firmly bonded to the outer layers 20, 20' to provide a stable supporting force, so that the sandwich-type cushioning packaging material 200 is not easy to collapse and deform, and can continuously provide a considerable cushioning protection effect.

Abstract

The invention discloses a sandwich type cushion packaging material. The material comprises a support cushion layer and at least one outer surface layer, wherein the support buffer layer comprises a plurality of cutting lines and a plurality of ribs; one rib is formed between every two adjacent cutting lines; each rib is provided with a plurality of first side convex parts and a plurality of second side convex parts which extend in a staggered mode; the first side convex part of one rib of two adjacent ribs is partially connected to the second side convex part of the other rib. and the at least one outer surface layer is adhered to the plurality of first side convex parts of the support buffer layer or the plurality of second side convex parts of the support buffer layer. The invention further provides a manufacturing method of the sandwich type cushion packaging material.

Description

technical field [0001] The present invention relates to a sandwich-type cushioning packaging material and its manufacturing method, in particular to a packaging material sandwiched with a cushioning layer to provide support, cushioning and protection, and to package and protect goods, and to manufacture sandwich-type cushioning packaging materials method. Background technique [0002] In order to ensure that the product goods are not damaged by packing or transportation during the back-end delivery process. At present, when packaging items, most of them use plastic bubble layer or Styrofoam to wrap the packaging, but there are still problems such as poor cushioning effect or environmental pollution. In order to solve the lack of plastic bubble layer and Styrofoam, a gas packaging bag was developed, which is heat-sealed into a sealed state to form an air column, and is equipped with an inflation port for inflation. When the gas is filled into the air column through the infla...
