How to Choose the Right Surface Protection Film and Avoid Problems

Apr. 17, 2024

The term " surface protection film " aptly describes its purpose — safeguarding critical surfaces from scratches, marks, abrasions, UV exposure, and contamination. This adhesive tape, known for its robustness and longevity, is composed of thin layers of film bonded together to form a protective barrier. It finds widespread use in various applications, from shielding a building's glass during construction to safeguarding newly manufactured goods. For instance, it's the shrink-wrap plastic covering your new refrigerator and the material used to shield fabricated parts, particularly in the automotive industry. Manufacturers of metal and plastic sheets also rely heavily on this protective film. Not only are they scratch-resistant, but they also mitigate sunlight and UV ray penetration.

10 Questions To Ask Before Choosing the Right Surface Protection Film

To ensure you choose the right protective film for your applications, ask these questions:

1. Will the film be applied to a rough or smooth surface?

Rough surfaces need thicker adhesive due to their larger surface area.

2. Is the surface clean and dry?

Dirty conditions can affect the film's performance.

3. Will the surface be painted or coated?

Consider potential chemical reactions between adhesives and coatings.

4. What type of surface needs protection?

Different surfaces require different adhesives for successful performance.

5. Will the film be exposed to high temperatures?

Consider the temperature range the adhesive can withstand.

6. Will the film be used outdoors?

UV rays can degrade adhesives over time, so consider the level of UV protection needed.

7. What is the project scope?

Determine if protection is needed for windows, moisture barriers, or other purposes.

8. Will the film be used for safety or security?

Consider if the film is for worker safety or intruder deterrence.

9. How long will the film adhere to the surface?

For long-term applications, additional components may be needed for a strong bond.

10. Will storage and transportation affect the film?

Consider the impact of extreme climates during transport and storage. Keep films in a cool, dry place.

Once applied to a clean, dry surface, protective film effectively prevents damage to that surface. While incredibly versatile, using the wrong protective film for the job can jeopardize both your timeline and lead to dreaded budget overages.

5 Common Problems with Surface Protection Film

Here are the most common challenges we have encountered of working with tape and surface protection film :

1. Poor Surface Adhesion : If the film peels off too easily, several factors could be to blame:

- The surface was not adequately cleaned or was contaminated by dust or moisture.

- Incorrect film selection for the project, leading to insufficient adhesive or inappropriate tack for the climate and conditions.

- Uneven stretching of the film during installation, causing distortion and ineffective sealing.

2. Debonding : If the film separates from the adhesive, it leaves a residue on the surface. Removal can be remedied by using a clean cloth dipped in an appropriate organic solvent such as ethanol or acetate. Care should be taken to avoid creating additional cosmetic problems during removal.

3. Edge Lift : This occurs when the ends of the protective film begin to lift off the surface. It is common in metal protection, especially with aluminum compared to steel. Again, choosing the right film for the job is crucial.

4. Difficulty Removing the Film : The quality of the pressure-sensitive adhesive is often the reason for this problem. Manufacturers who have not mastered this specialized adhesive technology may use ordinary adhesives with minor modifications, leading to undesirable outcomes. Overexposure to sunlight can also contribute to this issue, highlighting the importance of considering the UV rating and intended duration of adhesion before installation.

5. Ghosting : This refers to visible blemishes on surfaces intended to be protected. Residue buildup from markers, cleaners, or solvents used during surface preparation is often the primary cause of ghosting. Careful removal with diluted solvents can address this issue and ensure a seamless transition in construction projects.
