Black Opaque EVA Interlayer

HJ-G Black Opaque EVA Interlayer for Decorative Laminated Glass

HJ-G is a black opaque EVA interlayer developed for laminated glass where complete visual privacy, a uniform dark appearance and strong decorative contrast are required.

Unlike clear, frosted or translucent white EVA interlayers, HJ-G is designed to create a solid black visual effect inside the laminated-glass construction. It is suitable for partitions, decorative panels, furniture glass, signage and commercial interiors where seeing through the glass is not desired.

The black layer is enclosed between two glass sheets after lamination, allowing the decorative colour to become part of the laminated-glass structure rather than an exposed surface-applied film.

Key Highlights

• Uniform opaque black appearance

• Strong visual privacy
• Decorative colour enclosed inside laminated glass
• Suitable for black architectural and interior glass
• Standard thickness: 0.38 mm
• Width options: 2000 / 2200 / 2400 mm
• 50 m standard roll length
• Suitable for customized decorative glass projects

What Is HJ-G Black Opaque EVA Interlayer?

HJ-G is part of E&N HONJIA's decorative black-and-white EVA interlayer series.

During laminated-glass production, HJ-G is placed between two glass sheets and processed using vacuum and controlled heating.

Typical construction:

Glass / HJ-G Black Opaque EVA / Glass

After lamination, the interlayer bonds the glass layers together while producing a deep, uniform black appearance.

HJ-G is different from clear or frosted EVA because its main design function is not to diffuse the view — it is intended to block visibility through the panel and create an opaque decorative surface.

This makes it useful where designers want the appearance of black glass while retaining a laminated-glass construction.

The final appearance may still be influenced by:

• Glass type
• Glass colour
• Glass thickness
• EVA layer configuration
• Edge treatment
• Reflections from surrounding light
• Installation background

For colour-sensitive or large projects, a representative laminated sample should be reviewed before mass production.

Typical Laminated Glass Structure with HJ-G

Top Glass Layer

The upper glass sheet forms one of the finished surfaces of the laminated panel.

Clear, low-iron, tempered or other suitable glass may be selected according to the required finished appearance and glass construction.

HJ-G Black Opaque EVA Interlayer

HJ-G is positioned between the glass sheets.

During lamination, it bonds to the glass and creates the black opaque decorative layer.

Because the colour is inside the laminated construction, it is not simply a black adhesive film applied to the exposed outer face of finished glass.

Bottom Glass Layer

The second glass sheet completes the laminated construction and encloses the black EVA interlayer.

Why this structure is useful

This structure allows glass processors to combine:

• Laminated-glass construction
• Black decorative appearance
• Visual privacy
• Smooth glass surfaces on both sides

HJ-G Technical Specifications

The current HJ-G page lists the following product data.

Internal publishing note

The mechanical, aging and bare-edge values above are currently published on the existing HJ-G page. Before the revised version goes live, I recommend checking them once against the latest HJ-G TDS / internal QC record, particularly the bare-edge and exterior-use claims.

The Visual Character of HJ-G Black Opaque EVA

Deep Opaque Black Appearance

HJ-G is designed to produce a solid black visual surface in laminated glass.

Unlike smoked or tinted glass, the purpose is not simply to darken the view.

The HJ-G interlayer creates an opaque black layer so that objects behind the finished panel are not intended to remain visible.

Strong Visual Privacy

HJ-G is suitable for areas where transparency is unwanted.

This can be useful for:

• Privacy partitions
• Concealed areas
• Decorative wall surfaces
• Furniture panels
• Commercial interiors
• Signage backgrounds

Smooth Glass Surface

Because the black layer is located inside the laminated structure, both exposed faces can remain glass surfaces.

This can be useful where a designer wants a black visual effect without putting a decorative film directly on the external face.

Strong Contrast in Interior Design

Black laminated glass can create strong visual contrast with materials such as:

• Light stone
• White walls
• Natural timber
• Stainless steel
• Brass
• Aluminium
• Concrete
• Warm architectural lighting

This makes HJ-G particularly useful for modern commercial and hospitality interiors.

Applications of HJ-G Black Opaque Laminated Glass

1. Interior Partitions

HJ-G can be used where a glass partition is required but visibility through the panel is not.

Typical applications include:

• Private offices
• Back-office areas
• Meeting-room sections
• Residential partitions
• Service-area screens

The opaque black appearance creates separation while retaining the finish and detailing associated with glass.

2. Decorative Wall Panels

HJ-G laminated glass can be used as a decorative wall-facing material.

The deep black surface can work with:

• Reception walls
• Elevator lobbies
• Hotel corridors
• Feature walls
• Commercial entrance areas

The reflective glass surface and opaque black layer can create a different appearance from painted walls or ordinary solid panels.

3. Furniture and Cabinet Glass

Black opaque laminated glass can also be considered for:

• Cabinet doors
• Table panels
• Shelving elements
• Display furniture
• Kitchen or interior decorative panels

Actual glass thickness and finished construction should be selected according to the furniture design.

4. Retail and Display Environments

HJ-G can provide a dark background that helps merchandise, lighting or graphics stand out.

Possible applications include:

• Luxury retail displays
• Jewellery stores
• Cosmetic counters
• Showrooms
• Exhibition displays
• Brand presentation areas

5. Signage and Graphic Glass

HJ-G can be used as a black base layer for decorative glass signage or graphic panels.

It can provide a uniform dark background where strong visual contrast is required.

Compatibility and processing should be tested when the glass construction includes printing, inserts or other decorative materials.

6. Hotels, Restaurants and Hospitality Interiors

Black glass works particularly well in hospitality environments where designers want a more dramatic visual effect.

Typical locations include:

• Bars
• Restaurant screens
• Hotel lobbies
• Reception desks
• VIP areas
• Decorative columns
• Lift surrounds

7. Functional Concealment

Opaque glass can be useful where the purpose is to hide what is behind a panel.

Examples may include:

• Service zones
• Structural backgrounds
• Equipment areas
• Cabinet interiors
• Decorative backing panels

HJ-G should still be selected according to the complete glass construction and project requirements.

HJ-G vs Other Decorative EVA Interlayers

E&N's current product catalogue separately lists HJ-G as the Black Opaque EVA Interlayer, distinct from the jade, frosted and white-opaque grades.

Choose HJ-Y / HJ-Y2 when:

You want white or frosted privacy while still maintaining some transmitted light.

Choose HJ-S when:

You need a stronger frosted-white privacy effect.

Choose HJ-C2 when:

You want a strongly opaque white appearance.

Choose HJ-G when:

You want a black opaque decorative effect and do not want the background to remain visible through the panel.

HJ-G Black EVA vs Tinted Black Glass

HJ-G black opaque laminated glass should not be confused with ordinary dark tinted glass.

Dark Tinted Glass

Dark tinted glass reduces light transmission but may still allow objects or light sources behind the panel to remain visible.

HJ-G Black Opaque Laminated Glass

The HJ-G EVA layer is designed to create an opaque black visual layer inside the laminated glass.

Which should I choose?

Choose tinted glass when controlled transparency or solar appearance is required.

Choose HJ-G when the main requirement is:

• Privacy
• Concealment
• Black decorative appearance
• Minimal background visibility

Processing HJ-G EVA Interlayer

1. Film Preparation

Inspect the HJ-G EVA film on the production line.

Check for:

• Colour consistency
• Surface defects
• Contamination
• Film condition

As with your other EVA products, the film surface should remain clean and should not be touched unnecessarily during production.

2. Thickness Check

Measure film thickness using the appropriate thickness gauge according to the QC specification.

3. Full Roll Width Check

Measure the full width of the EVA roll with a ruler or measuring tape.

Confirm the actual roll width matches the required specification.

4. Clean the Glass

Make sure the glass is clean and dry before assembly.

Remove:

• Dust
• Oil
• Fingerprints
• Moisture
• Surface contamination

Black decorative glass can make certain contamination or local defects easier to notice after lamination.

5. Cut and Assemble

Cut HJ-G according to the glass dimensions.

Position the EVA film evenly between the two glass sheets.

Maintain a clean working area during assembly.

6. Vacuum and De-air

Place the assembled glass into the EVA vacuum bag.

Remove trapped air completely and confirm that the vacuum system is properly sealed.

7. Heating and Lamination

Place the vacuumed glass into an EVA vacuum laminating furnace.

The actual processing cycle depends on:

• Glass thickness
• Panel size
• EVA thickness
• Number of layers
• Vacuum performance
• Furnace characteristics
• Production conditions

A representative sample should be produced when introducing a new glass build-up.

8. Cooling

After lamination, allow the glass to cool under appropriate conditions before handling.

9. Final Inspection

Check the finished HJ-G laminated glass for:

• Uniform black colour
• Bubbles
• Edge condition
• Local colour variation
• Contamination
• Delamination
• Overall surface appearance
