[0003] Most of the existing decorative films are printed on one side, and a small number of decorative films are printed on both sides. Since the printing ink needs a certain amount of time to dry after printing, in order to avoid ink contamination of the guide roller, it is necessary to print on one side first, and then print on the other side after the ink cools down and dries, that is, double-sided asynchronous printing, which is inefficient and the patterns on both sides are easily misaligned, so it needs to be improved.

[0016] Combine the following Figure 1 to Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The film structure shown is conducive to double-sided simultaneous printing, including: a first base film layer 2, a second base film layer 4, a barrier layer 7, a first printing layer 8 and a second printing layer 5. The first base film layer 2 is covered on the top surface of the barrier layer 7, and the second base film layer 4 is covered on the bottom surface of the barrier layer 7. It can be composited by hot pressing to avoid separation problems and has a stable structure.

[0018] The first printing layer 8 is arranged on the top surface of the first base film layer 2, and the second printing layer 5 is arranged on the bottom surface of the second base film layer 4, and double-sided printing is performed. In this embodiment, the first base film layer 2 and the second base film layer 4 are respectively made of PVC film, which is convenient for the adhesion of ink. The barrier layer 7 can be made of aluminized film, which has good barrier properties and effectively avoids the mutual influence between the first printing layer 8 and the second printing layer 5.

[0019] In order to achieve double-sided synchronous printing, positioning holes 3 are arranged at intervals on the edges of the first base film layer 2 and located on both sides of the first printing layer 8. Figure 2 As shown, the positioning hole 3 penetrates downward through the barrier layer 7 and the second base film layer 4, and the second printing layer 5 is located between the positioning holes 3 on both sides, and can be matched with the positioning holes through a roller with a pin. The two rows of rollers are inserted into the positioning holes 3 in sequence during the rotation process to tension and guide the edges of the first base film layer 2 and the second base film layer 4 on both sides, so as to facilitate the double-sided simultaneous printing of the first printing layer 8 and the second printing layer 5, with high production efficiency, and synchronous cooling and curing after printing, without the need for the guide roller to contact the first printing layer 8 or the second printing layer 5.

[0020] In this embodiment, the width of the first printing layer 8 is smaller than the width of the first base film layer 2. Figure 1 As shown, the width of the second printing layer 5 is smaller than the width of the second base film layer 4, that is, the edge position of the positioning hole 3 does not overlap with the first printing layer 8 and the second printing layer 5, and the edge position of the positioning hole 3 can be cut after printing is completed or during use.

[0021] In order to avoid damage to the first printing layer 8 and the second printing layer 5, a first protective layer 1 is provided on the top surface of the first printing layer 8, and a second protective layer 6 is provided on the bottom surface of the second printing layer 5 to protect the first printing layer 8 and the second printing layer 5. In this embodiment, the first protective layer 1 and the second protective layer 6 are made of PP film, which can be covered by hot pressing and have a stable structure.
