Bubbles may form under the film if cutting gas escapes between the sheet and the film during cutting. The risks are as follows:

• a large bubble catching on the laser head and dragging the sheet away, resulting in uncontrolled movements and consequently significant damage.
• damage to the head and lens.

In 90% of cases, bubbling occurs during the drilling phase.

The risk of bubbling is amplified when the cuts are very close together. For example, small holes that are very close together. The gas pressure is concentrated on a very small surface and bubbles appear. There is also a strong risk of bubbling when the holes are less than 5mm apart. In this case, vaporisation must be carried out to avoid bubbling, i.e., burning the film before the cutting and, more specifically, the drilling phase. ‘Pre-drilling’ is available on most machines and can be done in the same operation as drilling, without significantly impacting productivity.

When the distance between the holes is greater, the holes are made in an area where the film is intact. There is therefore less risk of bubbles.
 

Protective film on sheet metal impacts the production process. Yet, suppliers standardise films, at the cost of optimising the cutting process. However, when the volumes are high enough, or if the film is applied in-house, then the manufacturer can choose a more suitable film.

When choosing the film, it’s important to find a balance between high adhesion to limit bubbles and low adhesion to make the film easier to remove.

A) With this in mind, there are several aspects to consider when choosing a film :

? the cutting technology: fibre laser source or CO2 laser
A fibre laser’s wavelength is ten times shorter than that of a CO2 laser and is not absorbed by the plastic. Thus, using a film designed for CO2 laser would create a very uneven cut if used with a fibre laser source. In fact, films specifically for fibre laser cutting have built-in absorbers.

? the material: stainless steel, aluminium, pre-lacquered,  etc.

Stainless steel/aluminium: Some materials are highly thermally conductive, e.g., aluminium, copper, etc. In this case, the heat spreads when cutting and can melt the film. The sheet protection for these materials therefore must be adapted, with a higher level of thermal resistance than a film for stainless steel, for example.

Pre-lacquered steel: Cutting pre-lacquered steel can be problematic if the lacquer used is not designed for good laser wave absorption. Even if there are specific films, the lacquer must be adapted, in particular with specific additives.

Double-sided: Double-sided protection can cause a small amount of burring during cutting, because the film on the table side retains the material. It is therefore recommended to use thin films, which reduce, or even eliminate, quality problems.

? Thickness of the sheet metal used
Depending on the thickness, the pressure of the cutting gas is different and therefore does not require the same level of adhesion. As a result, a film designed for thin sheet metal will result in a lot of bubbling if used on thick sheet metal.

? Material finishes: brushed, glossy, scotch-brite, etc.
Adhesion depends on the surface and the film products are adapted to each surface. It is therefore important to take the finish of the material into account when choosing a film.

B) Quality control: how to ensure that the film is suitable and properly applied?

? Specific colour codes and markings enable the operator to identify the type of film for visual inspection. Brice Lequette – Novacel explains: "The protective film for a CO2 laser is black on the glue side and white on the outside, whereas for a fibre laser it is black on the glue side and grey on the outside.”

? It is important to properly apply the film, especially by limiting its elongation. This is because plastic is a shape memory material that will return to its original size if elongated. Elongation reduces adhesion and the film will therefore be less resistant to gas pressure, leading to an increased risk of bubbling.

A quick test can be carried out to check that the film has been properly applied:

• peel off a strip of film from the sheet,
• wait a minute,
• compare the length of the removed film to the area where it was stuck. The difference should not be more than 1%.

A few visual clues can also alert to any issues, such as small application defects like bubbles, etc.

? The sheet metal should not be cut for 48 hours after applying the film.
 

The Ultimate Guide to Paint Protection Film

Your vehicle is one of your most valuable assets. Keeping it looking new is important for its resale value and appearance. One of the best ways to protect your car’s exterior is by using Paint Protection Film (PPF).

In this guide, we will explore everything you need to know about PPF. We will cover what it is, how it works, and why it is essential for any car enthusiast.

What is Paint Protection Film (PPF)?

Paint Protection Film, or PPF, is a thin, clear film made of thermoplastic urethane. People apply it to a vehicle’s painted surfaces. This film protects the car from scratches, rock chips, bug splatters, and minor abrasions.

Researchers first created PPF for military use to protect helicopter blades. Now, it is a popular way to keep cars looking new.

Manufacturers design PPF to be strong, self-repairing, and almost invisible after application. This makes it a smart choice for any car owner.

The Benefits of PPF for Your Vehicle

Protecting your car’s paint is most effectively achieved with Paint Protection Film. Here are some key benefits:

• Scratch and Chip Resistance: PPF acts as a barrier between your car’s paint and the harsh elements of the road. It protects against minor scratches, rock chips, and abrasions that can quickly damage the appearance of your vehicle.
• UV Protection: Prolonged exposure to the sun can cause your car’s paint to fade over time. PPF provides excellent UV resistance, helping to keep your paint looking vibrant and new for years.
• Self-Healing Properties: One of the most impressive features of modern PPF is its ability to self-heal. Minor scratches and swirl marks will disappear with heat from the sun or a heat gun, leaving your car looking flawless.
• Preserving Resale Value: Protecting your car’s paint will help maintain its value. A well-protected car is more appealing to potential buyers, allowing you to get the best price when it’s time to sell.

How is PPF Installed?

PPF installation is a delicate process that requires precision and expertise. Here’s what you can expect when having PPF installed on your vehicle:

PPF vs. Ceramic Coating: Which is Better?

Both Paint Protection Film and ceramic coatings are popular options for protecting your car, but they serve different purposes. Let’s compare the two:

• PPF: Offers superior protection against physical damage like rock chips, scratches, and minor impacts. Ideal for high-impact areas such as the front bumper, hood, and side mirrors.
• Ceramic Coating: Provides excellent protection against chemical contaminants like bird droppings, water spots, and road salt. However, it doesn’t offer the same level of impact resistance as PPF.

In many cases, using both PPF and ceramic coating is the best way to protect your vehicle’s paint. This combination helps guard against all types of damage.

How to Maintain Your PPF for Long-Lasting Protection

To get the most out of your Paint Protection Film, proper care and maintenance are essential. Here are a few tips:

• Hand Wash Only: Avoid automatic car washes, as the brushes can damage the film. Hand washing with a gentle automotive soap and microfiber cloth is the safest option.
• Avoid Harsh Chemicals: Do not use any abrasive or harsh chemicals that could degrade the film. Stick to pH-neutral cleaning products.
• Use a Paint Sealant: PPF does not need regular waxing. However, you can use a paint sealant made for PPF. This will improve its shine and make it last longer.
• Repair Scratches Quickly: If you notice any scratches or marks on the film, use a heat gun or let the sun’s heat help the film self-heal. In the case of deeper damage, you may need to seek professional repair.
