The EU CE certification has very strict environmental requirements for plywood, mainly reflected in the following aspects:

1.  Formaldehyde Emission Limits:

      Must comply with the E1 grade standard, meaning formaldehyde emission ≤0.124mg/m³ (determined by EN 717-1 chamber method).

      The EN 120 perforator method is also used for auxiliary determination.

2.  Limits for Other Hazardous Substances:

      There are clear limit requirements for the content of heavy metals (such as lead, cadmium, hexavalent chromium, mercury), pentachlorophenol (PCP), and Volatile Organic Compounds (VOCs).

3.  Sustainable Wood Source (Recommended):

      Although CE certification itself focuses more on the product's performance and safety, the EU market generally expects wood sources to meet sustainability standards, such as FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) certification. While not a mandatory requirement of CE certification, this helps enhance the product's market acceptance and competitiveness.

The production process of the EU CE Certified Plywood Standard Line is a systematic integration of precision engineering and stringent quality control, comprising the following steps:

1.  Raw Material Preparation & Processing: Logs are first peeled or sliced into thin wood veneers. These veneers are then fed into dryers to precisely control their moisture content within the range of 8%-12%, which is fundamental for ensuring subsequent bonding quality. The dried veneers are sorted, repaired to remove defects, and graded.

2. Glue Mixing & Application: Adhesives such as urea-formaldehyde (UF) or phenol-formaldehyde (PF) resin are precisely formulated according to the product's intended use (e.g., interior, exterior, moisture-resistant) and requirements (e.g., E0/E1 environmental standards). The adhesive is applied evenly onto the veneer surfaces using roller or curtain coaters, with strict control over the spread amount.

3.  Layup & Pre-pressing: The glued veneers are laid up manually or automatically into a mat according to the designed number of piles and grain direction (e.g., odd number of layers, cross-grained). The mat is then subjected to a short period of cold pressing. This pre-pressing step gives the mat initial shape, reduces misalignment, and facilitates handling and hot pressing.

4.  Hot Pressing & Curing: This is the core process. The pre-pressed mat is loaded into a high-temperature hot press. It is pressed under specific temperature (e.g., 140-160°C), pressure (e.g., 100-200 kg/cm²), and time settings. The heat and pressure cure (harden) the adhesive, firmly bonding the veneers into a solid panel.

5.  Cooling & Conditioning: The pressed panels exit the hot press at very high temperatures. They are immediately transferred to cooling racks for forced cooling to prevent deformation and the buildup of internal stress. After cooling, panels are often conditioned by resting in a controlled environment (constant temperature and humidity) for over 24 hours. This allows internal stresses to equilibrate and panel properties to stabilize.

6.  Trimming & Sanding: The conditioned panels are first trimmed to standard dimensions and their rough edges are cut off by panel saws (cross-cut and rip saws). Subsequently, the panels pass through wide-belt sanders for surface sanding. This ensures precise and consistent panel thickness and a smooth, flat surface, preparing them for further processing or direct use.

7.  Inspection & Testing: This is the critical step for ensuring compliance with the CE standard EN 13986. According to the requirements of the Factory Production Control (FPC) system, samples are taken at various stages of production and from finished products for testing. Key tests include, but are not limited to: dimensional accuracy, Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB) strength, formaldehyde emission (using the chamber method), bond quality, and moisture content.

8.  Grading, Packaging & Marking: Finished panels are graded based on inspection results. Conforming panels are packaged according to requirements. The packaging is clearly marked with the CE mark, manufacturer identification, product specifications, the standard number (EN 13986), and other information required for the Declaration of Conformity (DoC).

9.  Certification & Documentation: The entire production process operates under a Factory Production Control (FPC) system monitored by an EU Notified Body. The final product is accompanied by a Declaration of Conformity (DoC) and full performance certification reports, ensuring traceability and full compliance with the EU Construction Products Regulation (CPR).

The core advantages of the plywood produced by this line lie in its exceptional performance, strict compliance, and unmatched quality consistency, making it a passport to the EU and other high-end markets.

1. Superior Physical & Mechanical Properties

  High Strength Structure: High Modulus of Rupture (MOR ≥ 30MPa) and Modulus of Elasticity (MOE), excellent load-bearing capacity and deformation resistance, fully compliant with EN 13986 for structural use.

  Excellent Durability: Using Moisture-Resistant (MR) and Weather & Boil Proof (WBP) adhesives, products achieve Use Class 2 (humid conditions) or Class 3 (exterior conditions), resistant to aging and corrosion with a long service life.

  Outstanding Dimensional Stability: Precise processing ensures minimal thickness tolerance, low expansion, shrinkage, or warping under varying temperatures and humidity.

2. Top Environmental & Safety Standards

  Ultra-Low Formaldehyde Emission: Strictly controlled to E1 grade (≤0.124mg/m³) or stricter E0 standard, ensuring indoor air quality safety and health protection.

  Fire Safety: Can produce panels with B-C class fire performance (EN 13501-1), meeting building fire safety regulations.

  Hazardous Substance Control: Fully complies with EU CPR limits for heavy metals, Pentachlorophenol (PCP), etc., ensuring safety and non-toxicity.

3. Authoritative Certification & Compliance

  EU Market Access: Certified by an EU Notified Body, complete with CE marking, Declaration of Conformity (DoC), and technical documentation, fully compliant with the EU Construction Products Regulation  for free circulation in the EU market.

  Systematic Quality Assurance: Production under a Factory Production Control (FPC) system ensures traceability and control from raw materials to finished products, guaranteeing reliable and consistent quality.

4. High Customization & Consistency
