What is Mylar film?

Mylar film (also known as polyester film or boPET film) is a polyethylene terephthalate (PET) film made by biaxial stretching process. This special manufacturing process endows it with unique physical and chemical properties, making it stand out in the field of advertising materials.

Detailed explanation of the core characteristics of Mylar film:

High strength tensile performance

• The tensile strength can reach 150-250MPa, which is 3-5 times that of ordinary plastic film
• Tear resistance index exceeding 100N/mm, capable of withstanding significant external forces
• The Young’s modulus can reach 4000-7000MPa, ensuring that the material is not easily deformed
• Especially suitable for outdoor advertising applications that require long-term suspension

Optical performance

• The transmittance can reach over 90%, comparable to the transparency of glass
• Surface glossiness (60 ° angle) exceeds 100GU, presenting a mirror effect
• Mist level below 1.5%, ensuring clear and undistorted images
• Special surface treatment technology enhances ink adhesion

Excellent environmental tolerance

• Waterproof rating reaches IPX7, completely preventing moisture infiltration
• Temperature resistance range -70 ℃ to 150 ℃, suitable for various climatic conditions
• UV resistance performance passed 3000 hour QUV test without fading
• Excellent acid and alkali resistance, able to resist common chemical substances erosion

Excellent dimensional stability

• Heat shrinkage rate below 1.5% (150 ℃, 30min)
• The water absorption rate is less than 0.8%, and the impact of humidity changes is minimal
• Low creep rate, no deformation after long-term use
• Specially suitable for precision printing and composite processing

Long term weather resistance performance

• The amount of UV stabilizer added can reach 3-5%, extending its service life
• Passed ASTM G154 2000 hour aging test
• Outdoor service life can reach 3-5 years without fading
• Anti yellowing index Δ E<3 (3000 hour test)

Advantages of Mylar film in advertising applications

Super durability

• Compared to ordinary vinyl or paper advertising materials, Mylar film has:
• Strong weather resistance (waterproof, moisture-proof, high and low temperature resistance)
• UV resistant and non fading
• Wear resistant and have a long service life
• Especially suitable for:External billboards/banners, vehicle stickers/vehicle advertisements, window stickers/signage.

Excellent printing performance

• High gloss surface enhances color vividness
• Presenting fine graphic and textual details
• Ink adhesion is strong and does not peel off

 Lightweight and flexible

• Combining strength and flexibility, suitable for:
• Indoor advertising (posters, light boxes)
• Product packaging label
• Promotion stickers/decorative stickers

Mylar film type for advertising

How to scientifically choose Mylar film for advertising

Environmental considerations (key indicators)

Key points for outdoor application selection

• UV protection level: Select models with UV 380-400nm barrier rate ≥ 99%
• Weather resistance performance: requires 3000 hours of QUV accelerated aging test (Δ E<3)
• Temperature adaptability: Maintain stable performance over a wide temperature range of -40 ℃ to 80 ℃
• Wind resistance design: It is recommended to choose a thickness of 175-200 μ m and a wind resistance of ≥ 800Pa

Key points for indoor application selection

• Environmental certification: Priority should be given to products certified by GREENGUARD
• Fire rating: Public places must meet the B1 level flame retardant standard
• Optical performance: It is recommended to choose products with a transmittance of 85-92%

Special environmental response plan

• High humidity environment: Choose models with water vapor permeability<5g/m ² · 24h
• Chemical plant area: requires special coating treatment resistant to acid and alkali (pH2-12)
• Seaside area: choose salt spray resistant (500h test) enhanced type

Printing process matching (professional technology)

Key points for matching digital printing

• Surface tension: ≥ 42 dynes/cm (suitable for water-based ink)
• Ink absorption performance: The drying time should be controlled within 15-30 seconds
• Coating treatment: It is recommended to choose a specialized nanoporous coating (with a resolution of 1440dpi)

Technical requirements for screen printing

• Film surface hardness: Requires ≥ 3H pencil hardness
• Elastic modulus: It is recommended to choose products with a strength of 2000-3000MPa
• Ink adhesion: The hundred grid test needs to reach level 5B

Offset printing process adaptation

• Thickness tolerance: to be controlled within ± 2 μ m
• Static control: surface resistance of 10 ^ 6-10 ^ 8 Ω
• Dimensional stability: thermal shrinkage rate ≤ 0.5% (150 ℃)
