The conforming layer 30 can be stretched by the first handle layer 20 and/or the second handle layer 40 to be removed from the product.

In one embodiment, the protective layer 10 is a non-adhesive protective layer. The protective layer 10 is used to cover a product to protect the product.

In one embodiment, the adhesive layer 30 is a high-viscosity easy-open adhesive layer, and the viscosity is reduced or fails after stretching, so that the adhesive layer can be automatically separated from the protective layer 10 and the product without damaging the product.

The first handle layer 20 and the second handle layer 40 can be directly adhered to two sides of the adhesive layer 30 to cover a part of the adhesive layer 30, so that the adhesive layer 30 is prevented from being stuck by hands or tools or being stuck by products, and the adhesive layer 30 can be conveniently pulled.

The first handle layer 20 comprises a first handle face 201 and a second handle face 202 which are oppositely arranged, the second handle layer 40 comprises a third handle face 401 and a fourth handle face 402 which are oppositely arranged, the first handle face 201 is adhered with the first attaching surface 31, the third handle face 401 is adhered with the second attaching surface 32, and the second handle face 202 and the fourth handle face 402 are non-adhesive surfaces.

The first handle layer 20 comprises two first handle parts 21, and the two first handle parts 21 are respectively attached to two sides of the first attaching surface 31; the second handle layer 40 includes two second handle portions 41, the two second handle portions 41 are respectively attached to two sides of the second attaching surface 32, and the two first handle portions 21 are respectively disposed corresponding to the two second handle portions 41 to facilitate pulling. Preferably, the first handle portion 21 and the second handle portion 41 are both located outside the protective layer 10.

Preferably, an orthographic projection of the protective layer 10 on the first attaching surface 31 coincides with the first attaching region 311.

Preferably, an orthographic projection of the protection layer 10 on the first attaching surface 31 coincides with an orthographic projection of the second attaching region 321 on the surface of the product to be attached. It is understood that the first conforming surface 31 and the second conforming surface 32 can be identically shaped and correspondingly configured.

In the present embodiment, the adhesive layer 30 is in a rectangular sheet shape, and the first adhesive surface 31 and the second adhesive surface 32 are both rectangular, and it can be understood that the shapes of the adhesive layer 30, the first adhesive surface 31 and the second adhesive surface 32 can be adjusted according to the requirement.

Referring to fig. 5 and 6, another embodiment of the present application provides a protective film 100, similar to the previous embodiment, the protective film 100 includes a protective layer 10, a first handle layer 20, an adhesive layer 30 and a second handle layer 40, except that the protective layer 10 is an adhesive protective layer, the protective film 100 further includes a reverse adhesive layer 50 disposed between the protective layer 10 and the adhesive layer 30, and the reverse adhesive layer 50 is used for separating the adhesive layer 30 from the protective layer 10.

The first adhesive surface 51 is an adhesive surface and the second adhesive surface 52 is a non-adhesive surface. The adhesion of the first reverse adhesion surface 51 is greater than the adhesion of the protective layer 10, i.e., the protective layer 10 is a low-adhesion protective layer, and the first reverse adhesion surface 51 is a high-adhesion surface.

Referring to fig. 1 and 7, the workpiece 200 is a product to be attached, and the elements 210 on the workpiece 200 need to be protected. In use, the conformable layer 30 is adhered to the area of the work piece 200 to be adhered and the low or no adhesive protective layer 10 can cover and protect a portion of the work piece 200. In the present embodiment, the protective layer 10 covers the element 210.

When it is desired to remove the protective film 100, the first handle layer 20 and the second handle layer 40 are simultaneously stretched such that the conforming layer 30 is elongated and exhibits reduced adhesion or failure, thereby removing the protective film 100 from the workpiece 200.

The protective film 100 can be safely and reliably adhered to a product through the adhesive layer 30, and elements on the product are covered and fixed through the protective layer 10; the adhesive layer 30 can be removed from the product by stretching the first handle layer 20 and/or the second handle layer 40 while the low or no adhesive protective layer 10 can be easily separated from the product to avoid damaging the product. Therefore, the protective film 100 can protect the product to be attached, and can be easily torn off without damaging the product under the condition of ensuring a certain adhesive strength, thereby improving the yield of the assembly process.

In addition, other changes may be made by those skilled in the art without departing from the spirit of the invention, and it is intended that all such changes be considered within the scope of the invention.
