12MIL & 16MIL Automotive Security Window Film: Stronger Protection for Vehicle Glass
Enhanced protection against glass breakage, impact and forced entry with 711 SEVENHAE SH12 and SH16 security films
Vehicle glass is one of the most vulnerable parts of a car when facing accidental impact, attempted break-ins, vandalism or other unexpected safety risks.
To provide a higher level of protection for automotive glass, 711 SEVENHAE offers two heavy-duty security window film solutions: 12MIL and 16MIL.
Unlike conventional automotive window films that mainly focus on heat rejection, UV protection or privacy, our SH Series Security Films are developed with greater thickness and structural strength to help reinforce automotive glass.
When the glass suffers a strong impact, the film helps hold broken glass fragments together, reducing dangerous glass scattering while increasing resistance against forced penetration.
Our security film range currently includes:
SH12 - 12MIL Reinforced Security Film
SH16 - 16MIL Ultra Heavy-Duty Security Film
Both options are designed for different levels of automotive security requirements.
SH12 - 12MIL Reinforced Automotive Security Film

The 711 SEVENHAE SH12 is a 12MIL / approximately 0.305 mm reinforced automotive security film designed to provide a strong balance between glass protection, optical clarity and everyday usability.
Its thick multi-layer film structure creates an additional protective layer on the inside surface of automotive glass.
When the glass is struck or broken, SH12 helps keep the shattered glass attached to the film instead of allowing fragments to scatter immediately.
Key Features of SH12
Thickness: 12MIL / approx. 0.305 mm
Visible Light Transmission: ≥85%
UV Rejection: ≥99%
High tensile strength
High impact resistance
Helps hold shattered glass together
Helps delay forced penetration through vehicle windows
Designed for automotive security applications
10-year warranty
For vehicles requiring enhanced everyday security, SH12 provides an effective additional protective barrier against window smashing, accidental impact and attempted forced entry.
It is particularly suitable for customers who want significantly stronger glass protection without sacrificing normal driving visibility.
SH16 - 16MIL Ultra Heavy-Duty Automotive Security Film

For applications requiring an even higher level of protection, 711 SEVENHAE SH16 increases total film thickness to 16MIL / approximately 0.406 mm.
The heavier construction provides greater mechanical strength and stronger resistance against aggressive impact.
SH16 is developed for vehicles and applications where security is a higher priority, helping reinforce glass against repeated impact, vandalism and attempted forced penetration.
Key Features of SH16
Thickness: 16MIL / approx. 0.406 mm
Visible Light Transmission: ≥85%
UV Rejection: ≥99%
Higher tensile strength
Enhanced adhesion strength
Strong resistance against repeated impact
Helps retain broken glass fragments
Helps increase the time required to penetrate vehicle glass
Designed for higher-security automotive applications
10-year warranty
The thicker film structure makes SH16 especially suitable for customers looking for maximum automotive glass reinforcement and enhanced anti-vandalism protection.
What Happens When Automotive Glass Breaks?
Ordinary automotive glass can break rapidly under a heavy impact. Once shattered, glass fragments may separate or fall away, making it easier to gain access through the window.
With security film installed, the film forms a strong bonding layer across the glass surface.
Even when the glass itself is damaged, the security film helps hold the fragmented glass together, creating an additional obstacle against immediate penetration.
This can provide valuable extra resistance in situations such as:
Vehicle window smashing
Theft attempts
Vandalism
Forced entry
Accidental heavy impact
Flying objects or road debris
Other unexpected glass safety incidents
It is important to understand that security film does not make automotive glass unbreakable. Its purpose is to reinforce the glass system, retain broken glass and increase resistance against penetration.
12MIL or 16MIL: Which One Should You Choose?
Security Film SH12 SH16
Thickness 12MIL / 0.305 mm 16MIL / 0.406 mm
Protection Level Heavy Duty Ultra Heavy Duty
Glass Fragment Retention Excellent Excellent
Impact Resistance High Higher
Anti-Vandalism Protection Excellent Enhanced
Recommended Use Daily vehicle security Higher security requirements
UV Rejection ≥99% ≥99%
Warranty 10 Years 10 Years
For most upgraded automotive security applications, 12MIL provides strong protection and excellent practicality.
For customers who prioritize a higher level of resistance against aggressive impact and forced entry, 16MIL provides an even stronger security solution.
Built for Reliable and Consistent Protection
Security film is not only about thickness.
Material consistency, adhesive performance, tensile strength, optical quality and manufacturing stability all directly affect the final performance of the installed film.
711 SEVENHAE security films are manufactured under strict quality-control procedures and are developed with reference to recognized safety and quality standards.
Our SH security film series is designed to deliver:
Stable material quality, strong adhesive performance, reliable glass retention, high optical clarity and consistent production performance.
The products are developed and evaluated according to applicable safety and quality standards, including relevant impact-resistant transparent material standards and ISO 9001 quality-management requirements, while additional testing and certification requirements can be provided according to different markets.
Two Thicknesses. One Goal: Safer Automotive Glass.
From 12MIL reinforced protection to 16MIL ultra heavy-duty protection, 711 SEVENHAE provides different security-film options for automotive window protection.
Whether the requirement is everyday anti-smash protection or a higher level of anti-vandalism security, the SH Series provides an additional layer of protection between the vehicle occupants and the outside environment.
SH12 - Stronger Protection.
SH16 - Maximum Reinforcement.
