How to paste PE protective film to achieve better effect?

The PE protective film is as easy to use as a piece of tape. However, as the protective film strip increases in both width and length, the difficulty factor also increases a little in response. Handling a 4' wide by 8' long tape is a different matter than handling a 1' wide by 4' long tape. A bigger challenge is getting a large piece of PE protective film to perfectly align with the target surface and then lay it down without creating unsightly wrinkles or air bubbles, which can be difficult to handle, especially on irregular product surfaces. 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 to the other end of the product that needs to be protected, sticks that end to the target surface, and manually presses the protective film into place, towards the side holding the roll. people. This method is labor-intensive and low-efficiency, but the work effect is quite good. Another way to manually apply a large sheet of PE protective film to a large sheet of material is to apply the material to a film. The following describes a relatively simple method of applying bulk (4.5 x 8.5 ft) surface armor to 4 x 8 ft of material. 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 handling for this method to work successfully.) Steps to get the protective film perfectly on the product surface: 1. Prepare a suitable large and flat work space - than Objects to be protected are larger - clean and free of dust, liquids or contamination. 2. Apply 4.5 feet of double-sided tape near each end of the workspace...about 8.5 feet apart. These will be used to hold the film, not the material to be protected. 3. With the adhesive side up, unfold a small section of the protective film. Make sure it's smooth and wrinkle-free, and stick the loose end evenly over one of the double-sided tapes. 4. Continue to unfold the protective film and place it along the length of the work surface not far from the other double-sided tape. 5. Now, roll up the film and place it over the double-sided tape. Be careful not to pull the originally connected end of the tape out of the tape, adjust the orientation of the film to make sure the film is straight, not wrinkled, and tensioned properly, but not so tight that the film will shrink later. (When the film is stretched during use, there is a tendency for the edges to pull up as the film tries to return to its original shape.) 6. Lower the film onto the second strip of double-sided tape. 7. Using a utility knife, cut the roll from the film that is now waiting to receive the sheet to be protected. 8. 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. 9. Gradually place the parts 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 the sheet adheres to the film, apply pressure to the material, especially along all edges, to ensure a good bond. A clean paint roller may be used for this purpose. 11. Trace part of the outline on the protective film with a utility knife and cut off the excess film. Remove the excess and dispose of it. 12. Carefully invert the section and if necessary apply pressure directly to the film, working from the middle out to ensure good adhesion across the area. 13. Inspect the finished piece for complete, wrinkle-free coverage. For mass production, it is recommended to use a machine commonly known as a laminator to apply the protective film. This is especially useful when both sides of the paper need to receive a protective film, as the machine can apply to both sides at the same time.
