What Is Plywood? Definition, Types, and Why It’s a Go-To Material in Construction & Furniture

Posted by Thanh Uyên at 10/06/2025

Plywood is one of the most widely used materials in modern construction, interior design, packaging, and even marine applications. You’ve probably seen it at home improvement stores, construction sites, or inside furniture—but how much do you really know about what plywood is, how it’s made, and how it differs from other engineered wood like LVL or film-faced panels?

Let’s explore what makes plywood such a valuable material and why it continues to dominate the global wood industry.

What Is Plywood?

Plywood is an engineered wood product made by gluing together thin layers of wood veneer. These layers are arranged with their grain direction alternating at right angles, forming a cross-laminated structure. This construction provides plywood with excellent strength, dimensional stability, and resistance to warping, splitting, and moisture-related deformation.

To ensure structural balance, plywood is typically manufactured with an odd number of layers commonly 3, 5, 7, or more. This design makes it more stable and versatile than solid wood in many scenarios.

Plywood panels come in a variety of thicknesses, core types, sizes, and surface finishes depending on their intended use.

How Is Plywood Made?

The manufacturing process begins by peeling logs into thin sheets of veneer. These sheets are then dried, graded, and bonded together with adhesives.

The type of glue used is crucial. For example:

  • MR (Moisture-Resistant) glue is used for interior-grade plywood.

  • WBP (Weather and Boil-Proof) glue or phenolic resins are used for exterior and marine-grade plywood.

After glue application, the veneers are assembled with alternating grain directions and hot-pressed under heat and pressure to form a single, durable panel. The outer layers, known as face veneers, are selected for appearance, while core layers may vary in quality depending on the plywood grade.

Main Applications of Plywood

Thanks to its balance of strength and weight, plywood is used across many industries:

  • Construction: wall sheathing, subfloors, roof decking, formwork, scaffolding
  • Furniture: cabinets, beds, tables, shelving, doors
  • Packaging: crates, boxes, pallets for export
  • Marine and Outdoor: boat building, docks, outdoor signage (marine plywood only)

Types of Plywood You Should Know

  1. Commercial Plywood: The most common interior-grade plywood, used for furniture, partitions, and paneling. Usually made with poplar or eucalyptus core and MR glue.
  2. Packing Plywood: Low-cost plywood used for making crates, boxes, and export pallets. Strength is important, but aesthetic quality is not.
  3. Film-Faced Plywood: Covered with a waterproof film layer (often phenolic), this type is designed for concrete formwork, scaffolding platforms, and heavy-duty applications. Highly durable and reusable.
  4. Marine Plywood: Manufactured using WBP glue and high-grade veneers, marine plywood is ideal for use in wet or humid conditions. Common in boat construction.
  5. Birch Plywood: Made entirely from birch hardwood, this high-quality plywood features a fine grain, excellent screw-holding power, and minimal voids. Used in cabinetry, CNC machining, and premium furniture.

Is LVL Considered Plywood?

No. Laminated Veneer Lumber (LVL) is a different type of engineered wood.

While LVL is made from thin wood veneers like plywood, all layers in LVL are oriented in the same direction. This gives LVL superior strength along its length, making it ideal for beams, headers, and other structural load-bearing applications.

In contrast, plywood’s cross-laminated structure provides stability in multiple directions and is more suitable for panel-based uses.

How to Choose the Right Plywood for Your Project

Let’s say you’re building a bookshelf for your home office, and you plan to store heavy books, files, or even a printer on it. In this case, choosing the right type of plywood is critical. You’ll want something strong, stable, and able to hold screws tightly without warping over time. This is where birch plywood really shines. Made from multiple layers of dense hardwood veneer, birch plywood offers excellent load-bearing capacity and structural integrity. It’s less likely to sag, bend, or split, even under constant weight.

Not only is it strong, but birch plywood also has a clean, smooth surface, making it a great choice if you want your bookshelf to look good without needing a lot of finishing work. Compared to lower-grade plywood or softwood cores, it’s more expensive—but the durability and professional finish are worth it, especially for furniture that needs to last. So when strength and appearance both matter, birch plywood is often the smartest choice.

Technical Considerations When Buying Plywood

If you're sourcing plywood internationally, you should also consider:

  • Glue type: MR, E0/E1, WBP, or phenolic
  • Core material: poplar, eucalyptus, or birch
  • Surface grade: BB/BB, B/BB, etc.
  • Certifications: FSC, CE, CARB, JAS
  • Dimensional tolerance and moisture content
  • Packing method for container shipping

Suppliers with experience in global exports typically offer consistent quality, custom sizes, and flexible logistics to meet different market needs.
