How to use PE protective film correctly?

PE protective film is as easy to apply as a piece of adhesive tape. However, as the protective film strips increase in width and length, the difficulty factor increases accordingly. Handling a tape that is 4 feet wide by 8 feet long is quite different than dealing with a tape that is 1 inch wide by 4 inches long.
A bigger challenge is to perfectly align the large-format PE protective film with the target surface without producing unsightly wrinkles or air bubbles on the surface, which is difficult to deal with 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 roll of protective film while the other pulls the torn end over the other end of the product to be protected, sticks the end to the target surface, and manually presses the protective film into place, toward the side holding the roll. people. This method is labor intensive and has low work efficiency, but the work effect is quite good.
Another way to manually apply large sheets of PE protective film to large sheets of material is to apply the material onto a film. The following describes a relatively simple method of applying bulk (4.5 x 8.5 ft) surface armor to a 4 x 8 ft material. You will need a roll of double-sided tape and a box cutter. (Note: The material in question should be able to tolerate a certain amount of processing for this method to work successfully.)
How to perfectly stick the protective film on the surface of the product:
1. Prepare a suitable large, flat workspace - larger than the object to be protected - clean and free of dust, liquids or contaminants.
2. With the adhesive side up, unfold a short section of the protective film. Make sure it is smooth and wrinkle-free, and attach the loose end evenly to one of the strips of double-sided tape.
3. Continue unrolling the protective film, placing it along the length of the work surface not far from the other double-sided tape.
4. Roll up the film and put it on top, over the double-sided tape. Be careful not to pull the originally attached end out of the tape, orient the film so that the film is straight, not wrinkled, and reasonably taut, but not so tight that the film shrinks later. (When the film is stretched during use, the edges have a tendency to pull up as the film tries to return to its original shape.)
5. Lower the film onto 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 a piece of material on one end or side of the protective film. Place it where the film is held by the double-sided tape. Gradually place the part on the adhesive film. NOTE: If the material is flexible, roll it up by bending it slightly when you place it on the film, allowing air to escape 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 a good bond. A clean paint roller might work for this purpose.
8. Use a utility knife to trace the outline of the part on the protective film, cut off the excess film, delete the excess and process it. Carefully flip the section over, applying direct pressure to the film if needed, working from the center out to ensure good adhesion throughout the area, checking that the finished piece is complete, wrinkle-free coverage.
