Film Faced Plywood is a high-performance artificial board made by covering the surface of ordinary plywood with a special resin film (such as phenolic resin or melamine resin). This coating process makes it more waterproof, wear-resistant, and corrosion-resistant, and is widely used in construction, furniture, ships and other fields.
Main application scenarios
Construction engineering
Concrete formwork: used for pouring support of structures such as floors, bridges, tunnels, etc, accounting for more than 70% of the global use of film faced plywood.
Temporary protective panels: construction site enclosures, ground protection.
Furniture and decoration
Custom cabinets, bookshelves, desktops (matte or wood grain film is required to enhance aesthetics).
Laboratory countertops (chemical corrosion resistance requirements).
Ships and outdoors
Hull bulkheads, deck base (Marine Grade waterproof glue is required).
Outdoor billboards, container floors (UV-resistant coating is required).
Processing technology of film faced plywood
Film faced plywood is a composite material with a special film covering the surface of ordinary plywood. It is widely used in furniture manufacturing, interior decoration and building formwork. This plywood not only improves the utilization rate of wood, but also gives the product a richer appearance and stronger durability.
- Raw material preparation
Substrate treatment
Core board selection: full core hardwood (eucalyptus/birch)
Moisture content control: 8-12%
Surface treatment: double-sided sanding (180-240 mesh sanding belt), roughness Ra≤3.2μm
Preparation of laminating materials
Phenolic resin film (for building formwork): gram weight 120-150g/㎡, temperature resistance >200℃
PVC film (for furniture decoration): thickness 0.3-0.5mm, UV coating required
Adhesive: formaldehyde-free polyurethane glue (solid content ≥65%) - Veneer splicing and repairing
In order to meet the requirements of different sizes, veneers need to be spliced to form panels of the required size. During the splicing process, the interface must be tight and seamless, and if necessary, the defective parts must be repaired to ensure the flatness and aesthetics of the final product. - Gluing and assembly
The next step is the key step – gluing. Use special adhesive to evenly apply to the surface of the veneer, and then stack the veneers together according to a certain number of layers and directions to form an assembly. This step requires strict control of the amount of glue and the alignment between the layers.
Substrate Gluing
Glue Application: Double-sided coating 180-220g/㎡ (high-pressure airless spraying)
Glue Activation: Pre-drying to a moisture content of 5-8% (infrared drying line, 60-80℃) - Hot Pressing
After the assembly is completed, the hot pressing stage is entered to cure the adhesive under specific pressure and temperature conditions to form a solid overall structure. The selection of hot pressing parameters depends on the type of glue used and the specific specifications of the board. - Surface treatment and laminating
The hot-pressed plywood also needs to be sanded and other surface treatments to obtain a smooth and flat surface. The last step is to laminarize the board, that is, to firmly adhere the pre-prepared decorative or functional film to the plywood surface through hot melt adhesive or other means.
Film faced plywood is a type of plywood covered with a decorative or protective film. It is widely used in furniture, interior decoration, building formwork and other fields. When purchasing, you need to consider factors such as material, performance, and environmental protection. Here are some practical purchasing tips:
Substrate selection:
Wood types: Common substrates include poplar, pine and birch. Each type of wood has its own characteristics:
Birch: high hardness and good stability, suitable for scenes with high quality requirements, such as high-end furniture or structural parts.
Poplar: light and low cost, suitable for general decorative purposes.
Gluing process: Choose substrates bonded with environmentally friendly glue (such as E0/E1 grade) to avoid excessive formaldehyde. High-quality substrates should have no debonding, delamination or voids.
Thickness specifications: Choose the appropriate substrate thickness according to specific uses:
3mm, 9mm: suitable for decorative panels or non-load-bearing structures, such as wall decoration or ceilings.
18mm and above: suitable for occasions requiring higher strength and stability, such as furniture manufacturing or floor laying.
Lamination material: affects durability and appearance
Common lamination types:
PVC film: wear-resistant, waterproof, low price, but poor environmental protection.
PP/PET film: environmentally friendly and non-toxic, high temperature resistant, suitable for food grade or children’s furniture.
Matt/high gloss film: Matt film is anti-fingerprint, high gloss film is easy to clean, choose according to the decoration style.
Lamination thickness: 0.1–0.5mm, choose thick film (≥0.3mm) in public places or high-frequency use areas to enhance wear resistance.
Environmental protection:
F☆☆☆☆ (F4 stars): Formaldehyde emission ≤0.3 mg/L (dryer method).
Chinese standard (GB18580-2017)
E1 level: Formaldehyde emission ≤0.124 mg/m³ (climate chamber method)
Surface quality inspection: avoid defects
Flatness: observe whether the surface is smooth without bubbles, bumps or scratches.
Color uniformity: the coating color should be consistent, without spots or color difference, and the joints should be closely aligned.
Edge treatment: check whether the four sides of the board are tightly sealed, without burrs or debonding.
