PE protective film is as easy to use as a piece of tape. However, as the width and length of the protective strip increase, the difficulty factors increase. Handling 4-ft × 8-ft tape is a different thing than handling 1 in × 4 in one.
An even bigger challenge is to align the large PE protective film perfectly with the target surface and then drop it without creating unsightly wrinkles or bubbles, especially on the surface of irregular products. In order to better apply the protective film to the surface of the product and make it as perfect as possible, we need at least two people. One person holds the protective film roll, while the other person pulls the torn end to the other end of the product that needs to be protected, attaches that end to the target surface, and then manually presses the protective film into place, facing the person holding the roll. This method is very labor-intensive and inefficient, but the work effect is quite good.
Another way to manually apply a large piece of PE protective film to a large sheet of material is to apply the material to the film. A relatively simple method of applying large blocks (4.5 x 8.5 ft) of surface armor to 4 x 8 ft of material is described below. You will need a roll of double-sided tape and a utility knife. (Note: The material in question should be able to tolerate a certain amount of processing for this method to work successfully.)
How to perfectly attach the protective film to the surface of the product:
1. Prepare a suitable large and flat working space – larger than the object to be protected – clean, no dust, liquid or pollutants.
2. With the adhesive side facing up, unfold a short section of protective film. Make sure it’s smooth and wrinkle-free and stick the loose end evenly to one of the double-sided tapes.
3. Continue to unfold the protective film and place it along the length of the working surface not far from another double-sided tape.
4. Roll up the film and put it on it, more than double-sided tape. Be careful not to pull out the tape from the end of the original connection, adjust the direction of the film, make sure that the film is straight, no wrinkles, and reasonably tight, but not so tight that the film will shrink later. (When the film is stretched during use, the edges tend to pull up when the film tries to return to its original shape.)
5. Put the film on the second double-sided tape. Using a utility knife, cut the roll from the film that is now waiting to receive the sheet to be protected.
6. Place one edge of the piece of material on one end or side of the protective film. Place it where the film is clamped by double-sided tape. Gradually place the part on the adhesive film. Note: If the material is flexible, when you place it on the film, bend it slightly, rolling it up so that air escapes between the material and the film.
7. To ensure that the sheet adheres to the film, apply pressure to the material, especially along all edges, to ensure good adhesion. A clean paint roller may be used for this purpose.
8. Use a utility knife to trace part of the outline on the protective film, remove the excess film, remove the excess and dispose of it. Carefully flip the section and, if necessary, apply pressure directly to the film, working from the middle outwards to ensure good adhesion throughout the area, checking that the finished piece is intact and wrinkle-free coverage.
