HDPE Cross Laminated Film-60B is a high-strength functional film produced from high-density polyethylene through multi-layer co-extrusion, multi-direction stretching, 45° rotary cutting, and cross lamination technology.
Two or more stretched film layers are laminated at a 45° crossing angle to form a bidirectional reinforced mesh structure. This results in:
The film is specially suited for asphalt waterproof membranes and synthetic roofing underlayment, enhancing durability and reliability in roofing applications.
Traditional PE films often encounter problems when used in roofing membranes:
Such issues compromise waterproof performance, membrane longevity, and structural stability.
Ordinary films lack cross-direction reinforcement. Stress applied during installation or under environmental load is concentrated in one direction, leading to:
Our HDPE Cross Laminated Film uses a 45° cross-lamination structure that evenly distributes stress in both MD and TD directions.

Used as reinforcement in asphalt waterproof membranes to improve:
Provides a strong, dimensionally stable base layer for synthetic roofing underlayment:
This structure distributes stress across both MD and TD directions, reducing tearing and improving stability.
Q1: Can this film be used in both asphalt and synthetic roofing membranes?
Yes, the cross-laminated HDPE film is optimized for both applications.
Q2: What thickness is recommended for roofing underlayment?
Standard thickness: 0.10–0.12 mm. Custom thickness available for specialized applications.
Q3: Does the film resist tearing and puncture during installation?
Yes, the bidirectional cross-laminated structure improves tear and puncture resistance significantly.
