Detailed Implementation

[0031] The first embodiment of this application is as follows:

[0032] Please see Figures 1-2 ,in, Figure 1 This is a schematic diagram of the structure of the first embodiment of the present invention. Figure 2 This is a cross-sectional view of the first embodiment of the present invention.

[0033] This invention provides a bubble wrap comprising a paper base layer 101 and a paper laminating layer 102; the paper base layer 101 has multiple raised bubbles 103. This solution can replace bubble wrap for cushioning and protecting goods, and is more environmentally friendly.

[0034] In this specific embodiment, the paper bonding layer 102 is adhered to the paper base layer 101 with adhesive. Multiple raised air bubbles 103 are provided on the paper base layer 101, and the paper bonding layer 102 is adhered to the side of the paper base layer 101 away from the multiple raised air bubbles 103 with adhesive. The paper bonding layer 102 seals the openings of the multiple raised air bubbles 103, ensuring that each raised air bubble 103 is sealed with air. When packaging goods, the goods come into contact with the multiple raised air bubbles 103, which provide cushioning protection. Since both the paper base layer 101 and the paper bonding layer 102 are made of paper, they degrade quickly after disposal, making them relatively environmentally friendly. This method can replace bubble wrap for cushioning protection of goods, making it more environmentally friendly.

[0035] The bubble wrap described in this embodiment has multiple raised bubbles 103 on a paper base layer 101. A paper adhesive layer 102 is adhered to the side of the paper base layer 101 away from the multiple raised bubbles 103 by adhesive, and the paper adhesive layer 102 seals the openings of the multiple raised bubbles 103, so that each raised bubble 103 is sealed with air. When packaging goods, the goods come into contact with the multiple raised bubbles 103, which cushion and protect the goods. Since both the paper base layer 101 and the paper adhesive layer 102 are made of paper, they degrade in a short time after being discarded, making them relatively environmentally friendly. Using the above method, bubble wrap can be used to cushion and protect goods, which is more environmentally friendly.

[0053] The pressing frame 403 is slidably connected to and penetrated by the multiple support rods 401. After stacks of raw paper are placed on the placement plate 402, the pressing frame 403 is used to press them down on top to prevent the raw paper from spilling and becoming messy. When the raw paper needs to be removed, the pressing frame 403 can be moved upwards.
