Benefits of plywood with a film coating for formwork
a. Durable:
Formwork plywood that has been film-coated often includes a specific PET layer with anti-wear properties. In addition, film faced plywood is fungus-resistant and functional in all seasons, from summer to winter. Due to the highest quality wood treatment and most up-to-date technology that follows current market trends, they also have strong chemical resistance and endure longer.
b. Excellent moisture and water resistance
In order to reduce direct contact between water and aluminum, this type of plywood is particularly made with an exterior film covering surface for outdoor usage.
c. Easy to clean
Because the film on this plywood makes the smooth surface resistant to adhesion. As a result, cleaning film-coated plywood becomes easy. You can simply use a cloth and wipe the surface without spending hours wiping.
d. Repeatedly usable:
Due to the outer film coating, film faced plywood is used for both indoor and outdoor use. They can be used in the construction industry as well as in furniture making. It is commonly used for molding ceilings, walls, sewers, highways, house columns, etc. and can be used many times. Normally, a film faced plywood has a life cycle of 5-8 times depending on the glue and type of wood used. Thus, helping investors save investment costs and labor costs.
Film faced formwork plywood production process
The production process of film-coated formwork plywood is generally similar to the production process of other types of plywood, from the steps of cutting wood, drying, undergoing hot and cold pressing to create the bond between wood layers. However, film faced formwork plywood, as its name suggests, will be coated with a film and treated with edge paint to create aesthetics and increase functionality for plywood.
Step 1: Dry the wood
Wood is taken from nature, so the humidity is quite high from 35-40%. With such moisture, the wood can be damaged when pressed. Therefore, the wood after peeling off the outer shell will be dried to increase durability, increase the strength and water resistance of film-coated plywood.
Step 2: Plank
After being coated with a special moisture- and water-resistant glue, thin laminated wood boards will be arranged in layers so that they are perpendicular to the direction of the wood grain of each layer. Placing boards along the grain of the wood helps to increase elasticity and high shear strength.
Step 3: Cold pressed
This process helps shape the wood planks and increases the cohesion of the boards
Step 4: Hot pressing
The board after hot pressing will be super strong, bearing and durable. The compressive force of the board is from 120-150 tons/m2.
Step 5: Sanding and cutting edge
The surface of the plywood will be sanded to increase the flatness of the plywood, and cut the edges to the standard size, in preparation for the film coating process.
Step 6: Coating the film
2 sides of plywood will be coated with phenolic glue, then coated with film.
Step 7: Treat and paint the edge
To increase the sharpness and durability of plywood, 4 edges of the board will be treated for square and water resistant paint.
Step 8: Preservation
Although a glue with water- and moisture-proof properties is used, to ensure the longest use time and promote the best use, the finished product will be packaged and stored in cool, moisture-proof conditions, wet, insects, and termites.
Things to keep in mind when choosing film-coated plywood
Glue
Glue is a determining factor in the water resistance of film-coated plywood. There are 2 main types of glue: WBP (Water Boiled Proof) has water resistant properties, including 3 types: Phenolic, Melamine and MR (Moisture Resistant) with good moisture-proof properties.
Core
The type of wood commonly used to make the core in film-coated plywood is hardwood, eucalyptus, birch, oak, mixed wood, …
VINEXCO classifies plywood based on the quality of the core wood:
Grade AA: High quality full face wood veneer, at least 3 times hot plywood core, negligible thickness tolerance, suitable for export
Type AB: High quality plain face wood, 2-3 times hot plywood core, flat surface, low thickness tolerance
Film
Currently, VINEXCO is using Dynea and Stora Enso films, both of which are high-end, beautiful and durable film brands, often used for high-quality film faced plywood products.
