AI Technical Summary
The existing decorative strips made of plastic have defects in surface gloss and texture, which are difficult to meet the needs of high-end decoration. At the same time, their optical reflection paths are too regular, resulting in a dull and monotonous light refraction effect, which cannot produce dynamic light and shadow changes, and cannot adapt to the needs of modern decoration designs that emphasize spatial hierarchy and visual fluidity.
The spiral gloss decorative strips are made of PET material. A double-layer structure is formed by plating aluminum on the PET film and rolling mechanically. Then a spiral structure is formed by a mechanical twisting device. Combined with the gloss effect of the metal plating, the dynamic light and shadow refraction effect is achieved.
The dynamic light and shadow refraction effect is achieved, which significantly improves the decorative effect and meets the needs of modern decorative design. At the same time, the durability and service life of the decorative strips are improved through double-layer structure reinforcement.

[0025] In this embodiment, the decorative strip body 100 further includes a first color layer 103 and a second color layer 104. The first color layer 103 is provided on the inner side surface of the base material layer 101, and the second color layer 104 is provided on the outer side surface of the metal coating layer 102; the thicknesses of the first color layer 103 and the second color layer 104 are 4 μm. The first color layer 103 and the second color layer 104 are formed by printing or coating with a conventional paint added with pigments or dyes. The color of the decorative strip body 100 is determined by the first color layer 103 and the second color layer 104, and one or more colors can be used according to needs.
[0026] The preparation process of this PET spiral gloss decorative strip is briefly described as follows:
[0027] During production, first select a PET film with a thickness of 0.5 mm as the base layer 101, and then vacuum deposit aluminum on the surface of the PET film to form an aluminum deposition layer, thus making a PET aluminized film; then use intaglio printing technology to coat and print the first color layer 103 and the second color layer 104 on both sides of the PET aluminized film to make a decorative film material with a gloss effect; subsequently, use a slitter to slit the decorative film material into the required width (such as 50 mm) to form the decorative strip body 100; subsequently, use mechanical heating and rolling on the wide surface of the decorative strip body 100 to fold it in half transversely to form a double-layer structure, and the crease line 105 at the folding place serves as a reinforcing rib; subsequently, twist the decorative strip body 100 through a mechanical twisting device to make it form a spiral structure with a pitch of 20 - 200 mm, thereby obtaining the PET spiral gloss decorative strip.
