How to use PE protective film correctly?

time:2021/2/26 10:22:29 browse:

PE protective film is as easy to use as tape. However, as the width and length of the protective film strip increase, the degree of difficulty will increase slightly. The bigger challenge is to make a large piece of PE protective film perfectly aligned with the target surface, and then put it down without unsightly wrinkles or bubbles, especially on the surface of irregular products.

In order to better stick the protective film on the surface of the product and make it as perfect as possible, we need at least two people. One person holds the protective film reel, while another person pulls the torn end to the other end of the product to be protected, sticks one end to the target surface, and then manually presses the protective film against the person holding the reel. This method has high labor intensity and low efficiency, but the effect is very good.

Another way to manually apply a large piece of PE protective film to a large piece of material is to apply the material to the film. The following describes a relatively simple method of applying large (4.5 x 8.5 feet) surface armor to a 4 x 8 feet material. You will need a roll of double-sided tape and a knife. (Note: The material in question should be able to withstand a certain amount of processing so that this method can run successfully.)

How to perfectly paste the protective film on the surface of the product:

1. Prepare a suitable large and flat work area-larger than the object to be protected-clean and free of dust, liquid or contaminants.

2. Put 4.5 feet of double-sided tape near each end of the workspace... about 8.5 feet apart. These will be used to fix the film, not to protect the material.

3. Unfold a small part of the protective film so that the adhesive side is facing up. Make sure it is smooth and wrinkle-free, and evenly stick the loose end on one of the double-sided tapes.

4. Continue to unfold the protective film and place it not far from the other double-sided tape along the length of the work surface.

Now, roll up the film and place it on top of the double-sided tape. Be careful not to pull the end of the original connection out of the tape. Adjust the direction of the film to ensure that the film is straight, wrinkle-free, and reasonably tightened, but not too tight to prevent the film from shrinking later. (When the film is stretched in use, when the film tries to restore its original shape, its edges tend to pull up.)

6. Lower the film onto the second double-sided tape.

7. Use a utility knife to cut the reel from the film waiting to receive the paper to be protected.

8. Place one edge of a piece of material on one end or one side of the protective film. Place it in the position where the double-sided tape holds the film.

9. Gradually place the components on the adhesive film. Note: If the material is flexible, when you place it on the film, bend it slightly to roll it up and allow air to escape between the material and the film.

10. To ensure that the sheet adheres to the film, apply pressure to the material, especially pressure along all edges, to ensure good adhesion. Cleaning the paint roller can be used for this purpose.

11. Use a utility knife to trace the partial outline of the protective film, and then cut off the excess film. Delete the redundant part and deal with it.

12. If necessary, please turn the parts carefully, apply pressure directly to the membrane, and operate from the middle to the outside to ensure that the entire area can adhere well.

13. Check whether the finished product is complete and without wrinkles.

For mass production, it is recommended to use a machine commonly called a laminator to apply the protective film. This function is particularly useful when a protective film is required on both sides of the paper, because the machine can be applied to both sides at the same time.
