Cross Laminated Film
HDPE cross laminated film manufactured for high strength, tear resistance and dimensional stability in waterproof membranes, roofing underlayment, tape and other reinforced film applications.
UPASS offers 60B, 60C and 60F cross laminated film grades, allowing manufacturers to select the appropriate film according to mechanical performance, elongation and surface requirements.
1. What Is Cross Laminated Film?
Cross Laminated Film for Reinforced Film Applications
Cross laminated film is a reinforced polyethylene film structure produced by orienting film layers in different directions and laminating them together.
This cross-oriented structure helps distribute mechanical stress across both the machine direction (MD) and cross direction (CD), providing a combination of tensile strength, tear resistance, elongation, making the film thinner yet stronger in performance.
Compared with a conventional single-direction oriented film, cross laminated film can provide more balanced mechanical performance in applications where the film may experience stress from different directions.
UPASS manufactures HDPE cross laminated film for downstream manufacturers that use the material in waterproofing, roofing and other industrial film structures.
2. Cross Laminated Film Series
UPASS currently offers three grades:
60B — High-Strength Grade
Designed for applications where higher maximum tension and strong mechanical performance are important.
60C — High-Elongation Grade
Designed for applications where higher elongation at maximum tension is required while maintaining high tensile strength.
60F — Anti-Slip Grade
Designed with an anti-skid surface treatment for roofing membrane applications, particularly where improved traction is required on sloped surfaces.

3. 60B / 60C / 60F — Which Grade Should You Choose?
Choose 60B When
You need a cross laminated film with a higher specified maximum tension and strong mechanical performance.
Key focus:
- Tensile strength
- Maximum tension
- Tear resistance
- Dimensional stability
Choose 60C When
Your application requires higher specified elongation while maintaining a tensile strength of ≥50 MPa.Performance of 60C: Resistant to yellowing; the waterproofing membrane has a better appearance than that made with 60B.
Key focus:
- Higher elongation
- Flexibility-related performance
- Tensile strength
- Aging performance
Choose 60F When
Your roofing membrane requires an anti-slip surface for installation on sloped roofing surfaces.
Key focus:
- Anti-slip surface
- Roofing applications
- Wet and dry working conditions
- MD/CD physical strength
4. Cross Laminated Film for Waterproof Membranes
Cross laminated film is used by waterproofing membrane manufacturers as a reinforced film or substrate within different membrane constructions.
The film can provide mechanical reinforcement and support the membrane's requirements for tensile strength, tear resistance and elongation.
UPASS cross laminated film grades can be evaluated for applications including:
- Asphalt-based waterproofing membranes
- Synthetic roofing membranes
- Roof underlayment
- Reinforced waterproofing structures
For waterproofing membrane manufacturers, film selection should consider the membrane construction, production process, bonding system, thickness and required mechanical performance.
5. Anti-Slip Cross Laminated Film
For roofing applications where workers need to operate on sloped surfaces, UPASS 60F provides a specially treated anti-slip surface.
The textured surface is designed to improve traction under wet and dry conditions while maintaining the reinforcement characteristics of cross laminated film.
60F is available in 75–200 μm basis thickness and 200–1060 mm width, with an anti-slip layer of 5–10 g/m².
6. Applications
