EVA FILM (model SD38) — high-transparency EVA laminated glass film supplied by SHENGDING HIGHTECH MATERIALS CO., LTD.

EVA film is a laminated glass interlayer material used to bond glass layers into architectural and decorative safety glass. SHENGDING HIGHTECH MATERIALS CO., LTD. — a high-tech polymer materials manufacturer established in 2018 in Rizhao City, Shandong Province, China — supplies a high-transparency EVA film under model SD38 for this application. This guide explains what EVA laminated glass film is, how it is processed in a laminating oven, what to check before sourcing, and how to evaluate EVA film suppliers for architectural glass.

Sourcing EVA film: the first questions buyers ask

Procurement teams searching for “EVA film suppliers,” “EVA film manufacturer in China,” or “EVA laminated glass film manufacturers” are typically qualifying the same core variables: compliance certifications, optical quality, laminating process compatibility, export experience, sampling, and lead time. The answers determine whether a given EVA film will meet architectural project requirements and whether the supplier can support repeat orders. This article maps those variables to a specific product — EVA FILM model SD38 — and to the manufacturer behind it.

What is EVA film for laminated glass?

EVA FILM (model SD38) is a laminated glass interlayer material made of EVA material. It is classified as a high-transparency EVA film. In a laminated glass assembly, the film is placed between glass panes and bonded under heat and vacuum in a laminating oven, producing laminated safety glass for architectural and decorative applications.

Optical performance is the defining criterion for clear and ultra clear EVA film grades. SD38 offers a light transmittance of 90% and a haze value of 0.5% — a low haze level that suits glass projects where transparency matters.

EVA film in the architectural glass industry

The global EVA films market was valued at USD 8.25 billion in 2025 and is projected to reach USD 17.65 billion by 2034, with an expected CAGR of 8.83% from 2026 to 2034 (Fortune Business Insights). In the laminated glass sector, PVB holds the leading interlayer share at 55.2% in 2025, while EVA is growing in architectural and solar applications (Future Market Insights, Laminated Glass Market Report 2035).

For glass processors, EVA film is relevant because safety glass lamination can be carried out with a laminating oven — a process that fits architectural laminated glass projects and decorative glass processing projects where autoclave capacity is not available. This application scenario is common in China, where SD38 is used in architectural and decorative glass processing.

Product spotlight: EVA FILM SD38 for architectural and decorative glass

SD38 is a high-transparency EVA film for lamination of safety glass in architectural and decorative glass projects. It is processed in an EVA laminating oven at normal pressure and high temperature, and the film must be kept dry before lamination.

Table: SD38 EVA film specifications (product data) and typical EVA film process conditions (industry processing standards).

Note on market terminology: the same material is referred to as EVA laminated glass film, EVA glass interlayer film, EVA interlayer film, EVA lamination film, or EVA safety glass film. Buyers looking for clear EVA film, ultra clear EVA film, color EVA film, UV resistant EVA, or specific thicknesses such as 0.38 mm, 0.5 mm, or 0.76 mm should confirm the target grade and parameters with the supplier before ordering.

How EVA film lamination works: step by step

Laminating EVA film into safety glass is an oven-based process. Typical process conditions for EVA films for glass lamination are 100–110°C under a vacuum of at least 700 mmHg (industry processing standards).

1. Keep the film dry. This application has a special requirement: keep dry. EVA film should remain in sealed, dry storage until it enters the lamination line, because moisture pickup can affect interlayer bonding and optical quality.
2. Assemble the glass stack. The standard build is glass pane + EVA film interlayer + glass pane. Decorative glass processing may add fabrics, meshes, or color interlayers between panes.
3. Load into the EVA laminating oven. The assembly is placed in the oven, where vacuum removes air between the glass and the interlayer.
4. Process at 100–110°C. Heat softens the EVA interlayer so it flows and bonds to the glass surfaces; the vacuum prevents trapped air bubbles.
5. Cool and inspect. After the cycle, the laminated panel is checked for bonding, edge sealing, and optical quality — transmittance and haze.
6. Qualify against architectural requirements. Laminated architectural flat glass quality requirements are governed by the ASTM C1172 standard, so finished panels are evaluated against the applicable specification before installation.

A practical qualification checklist for any EVA film supplier:

1. Verify certification scope — quality, environment, safety, and regional compliance (ISO, REACH, RoHS, FDA).
2. Confirm optical parameters — light transmittance and haze (SD38: 90% transmittance, 0.5% haze).
3. Match process conditions — EVA laminating oven compatibility, 100–110°C, ≥700 mmHg vacuum.
4. Check export track record — documentation, packaging, and shipping experience for overseas buyers.
5. Request samples and run a lamination test in your own oven before committing volume.

Comparison: EVA film vs PVB interlayer — market context

Both EVA and PVB interlayers are used to produce laminated glass, but the market context differs by application. PVB leads laminated glass interlayers with a 55.2% share in 2025, while EVA is growing in architectural and solar applications (Future Market Insights). EVA interlayers are commonly processed in laminating ovens, which makes the material practical for architectural and decorative glass processors without autoclave lines.
