[ first embodiment ]

Referring to fig. 1 to 4, an embodiment of the present invention provides a sandwich-type cushioning packaging material 100, which includes a supporting cushioning layer 10S (see fig. 2 and 3) and an outer skin 20. The outer skin 20 is adhered to one side of the support cushion 10S. In this embodiment, the supporting buffer layer 10S and the outer surface layer 20 may be made of kraft paper, which may meet the trend of environmental protection. The invention is not limited thereto and, for example, planar layers of material that can be bonded can be produced.

The invention discloses a method for manufacturing a sandwich type cushioning packaging material, which comprises the following steps: as shown in fig. 1, a planar support layer 10 is provided, and a plurality of cutting lines 11 are formed on the planar support layer 10. One rib 12 is formed between two adjacent cutting lines 11, each cutting line 11 has a plurality of notches 110, and the notches 110 of two adjacent cutting lines 11 are staggered. In the present embodiment, the plurality of cuts 110 are equal in length, and the cutting lines 11 are parallel to each other and are straight and dotted, but the present invention is not limited thereto, and the cuts may be arc-shaped or S-shaped.

The planar support layer 10 is stretched toward both sides in a direction perpendicular to the cutting line 11 as indicated by an arrow in fig. 1 to form a support buffer layer 10S as shown in fig. 2. Each of the ribs 12 is formed with a plurality of first side protrusions V1 and a plurality of second side protrusions V2 along the plurality of slits 110, the first side protrusion V1 of one of the ribs 12 of any two adjacent ribs 12 being connected to the second side protrusion V2 of the other rib 12. Described by another angle, the ribs 12 on both sides of each slit 110 are stretched away from each other toward both sides during the stretching of the planar support layer 10. Each of the slits 110 has an uncut portion (located between the slits 110) on both sides thereof, and the uncut portion is inclined due to the outward pulling force of both sides.

As shown in fig. 1, in the present embodiment, the length of the uncut portion between two cuts 110 is shorter than the length of one cut 110, that is, the projection of one front end of the cut 110 along the direction perpendicular to the cutting line 11 overlaps the other front end of the cut 110 of the adjacent cutting line 11. Thus, as shown in fig. 2 and 3, during the stretching process of the planar support layer 10, the ends of the two slits 110 on both sides of the same rib 12 are connected obliquely.

The method of manufacturing the sandwich-type cushioning packaging material 100 of the present invention further comprises, as illustrated in fig. 2, applying an adhesive G on at least one side of the supporting and cushioning layer 10S. The adhesive G may be sprayed or roll-coated. Finally, as shown in fig. 3 and 4, an outer layer 20 is provided to be adhered to one side of the supporting buffer layer 10S. In other words, the outer skin 20 is adhered to the first side protrusions V1 of the support buffer layer 10S or adhered to the second side protrusions V2 of the support buffer layer 10S.

Wherein the first side protrusion V1 protrudes toward one side surface of the support buffer layer 10S, and the second side protrusion V2 protrudes toward the other side surface of the support buffer layer 10S.

Along the same rib 12, each of the first side protrusions V1 has a first connecting section 12C and a first slope section 122, the first slope section 122 is connected to one end of the first connecting section 12C in a bending manner, each of the second side protrusions V2 has a second connecting section 12D and a second slope section 124, the second slope section 124 is connected to one end of the second connecting section 12D in a bending manner, the other end of the second slope section 124 is connected to the other end of the first connecting section 12C, and the second connecting section 12D and the first connecting section 12C are located on the same slope.

Wherein the second side convex V2 of one of the ribs 12 of two adjacent ones of the ribs 12 is not connected to the first side convex V1 of the other one of the ribs 12, but is partially connected to the first side convex V1 of the outer one of the ribs 12.

As shown in fig. 4, the second connecting section 12D and the first connecting section 12C form an inclined angle θ with respect to the outer surface layer 20, and the inclined angle θ is between 15 degrees and 80 degrees.

As shown in fig. 2 to 4, wherein the plurality of ribs 12 form a plurality of nested cells 110S, the outer edges of the plurality of first side protrusions V1 or the outer edges of the plurality of second side protrusions V2 are disposed with adhesive G to be respectively bonded to the outer skin 20 to fix the plurality of nested cells 110S.

As shown in fig. 4, the sandwich type cushioning packaging material 100 of the present invention may be formed by laminating two sheets of the sandwich type cushioning packaging material 100 and then bonding the edges of the two sheets of the sandwich type cushioning packaging material 100 to form a thicker thickness.

[ second embodiment ]
