What are the factors that affect the quality of film faced plywood?

1. Core Material Quality

• The type of wood used (e.g., poplar, birch, or hardwood) affects strength and durability.

• Poor-quality cores may lead to delamination or warping.

2. Film Coating (Overlay) Quality

• High-density phenolic film ensures better water resistance and wear resistance.

• Low-quality film may peel off or wear out quickly.

3. Glue Adhesive Quality

• Waterproof glue (e.g., WBP – Weather & Boil Proof) is essential for moisture resistance.

• Weak glue can cause plywood layers to separate.

4. Production Process & Pressing Technology

• Proper heat and pressure during pressing ensure strong bonding.

• Inconsistent pressing may lead to weak spots or bubbles in the film.

5. Moisture Content

• High moisture levels can cause swelling, mold, or deformation.

• Proper drying of wood veneers before production is crucial.

6. Thickness & Density Consistency

• Uneven thickness affects structural stability.

• Higher-density plywood is more durable but heavier.

7. Surface Smoothness & Defects

• Imperfections like knots, cracks, or rough surfaces reduce usability.

• A smooth film surface ensures easy concrete demolding.

8. Environmental Conditions & Storage

• Exposure to extreme humidity or sunlight can degrade the film and core.

• Improper storage may lead to bending or fungal growth.

9. Compliance with Standards

• Meeting international standards (e.g., EN 636, BS 1088) ensures reliability.

• Substandard plywood may fail under heavy loads.
