Differences Between Glossy Film and Matte Film in Label Protection and Visual Style, and Selection Guide
Last week, a client from an emerging food brand asked me: "Should my label be laminated with glossy film or matte film?"
I said: "It depends on where your shelf is + how far away the consumer is viewing it—two completely different optical principles."
He said, "Optical principles?"
I said: "Glossy film is specular reflection (light reflects in parallel), while matte film is diffuse reflection (light scatters in all directions)—the visual effects are completely opposite. This article won't discuss 'which looks better'—it will explain the 3-layer structure of lamination + optical principles + selection decisions."
The 3-Layer Structure of Lamination
| Layer | Material | Thickness | Function |
|---|---|---|---|
| Outer Layer | BOPP / PET / Holographic Film | 12-25 μm | Protection + Visual |
| Middle Layer | EVA Hot-Melt Adhesive | 5-10 μm | Bonding |
| Base Layer | Substrate (Paper / Film) | 50-200 μm | Print Carrying |
Total Thickness 67-235 μm—Laminated labels are 0.02mm thicker than bare labels.
Optical Principles: Specular Reflection vs. Diffuse Reflection
Gloss Lamination: Specular Reflection
Principle:
Incident light → smooth film surface → parallel reflection (same direction) Observer sees: bright, glaring reflection
Visual Characteristics:
- High reflection intensity (70–90% reflectance)
- Precise reflection angle (light source angle = angle at which reflection is seen)
- Eye-catching from a distance
Application Scenarios:
- FMCG products (attract attention from a distance)
- Shelf display (eye-catching from afar)
- Outdoor advertising (visible under strong light)
Matte Lamination: Diffuse Reflection
Principle:
Incident light → frosted film surface → scattered reflection (multiple directions) Observer sees: soft, even light
Visual Characteristics:
- Moderate reflection (30–50% reflectance)
- Soft sheen visible from every angle
- Close-up texture feel
Application Scenarios:
- Mid-to-high-end products (close-up tactile experience)
- Cosmetics (fine frosted texture)
- Gift boxes (matte sense of ceremony)
No Lamination: No Reflection
Principle: The paper directly reflects/absorbs light.
Visual Characteristics:
- Low reflection (10–20% reflectance)
- Natural matte appearance
- Raw tactile feel
Application Scenarios:
- Low-end FMCG (cost-sensitive)
- Non-wear-resistant scenarios (short-term use)

3 Types of Lamination Films
Material 1: BOPP Film (Most Commonly Used)
Full Name: Biaxially Oriented Polypropylene Film
Thickness: 12-25 μm
Cost: 0.05-0.1 yuan/sheet
Features: Low cost, balanced performance, available in glossy/matte finishes
Material 2: PET Film (Heat-Resistant)
Full Name: Polyester Film
Thickness: 12-23 μm
Cost: 0.15-0.3 yuan/sheet
Features: Heat-resistant up to 150℃, high strength, tear-resistant
Material 3: Holographic Film (Premium)
Full Name: Rainbow Light Film
Thickness: 20-25 μm
Cost: 1-3 yuan/sheet
Features: Rainbow color shift, premium feel, anti-counterfeiting
Product Type × Lamination Selection
Selection 1: FMCG (Food / Daily Necessities)
Recommended: Glossy film + BOPP (basic combination)
Reason: Eye-catching from a distance, low cost
Cost: +0.1 yuan/sheet
Selection 2: Cosmetics (Mid-to-High-End)
Recommended: Matte film + BOPP (texture combination)
Reason: Cosmetics feature a delicate touch; matte film matches it
Cost: +0.1 yuan/sheet
Selection 3: Electronic Products
Recommended: Matte film + PET (heat-resistant combination)
Reason: PET withstands 150°C, tear-resistant, matte film prevents glare
Cost: +0.3 yuan/sheet
Selection 4: Baijiu Gift Boxes
Recommended: Matte film + BOPP + hot stamping
Reason: Matte film as the base + hot-stamped LOGO, strongest sense of ceremony
Cost: +0.4 yuan/sheet
Selection 5: QR Code Labels
Recommended: Matte film + BOPP (required for scanning)
Reason: Glossy film causes glare and scanning failure; matte film is compatible
Cost: +0.1 yuan/sheet
Lamination Common Issues + Solutions
Issue 1: Label becomes stiff after lamination
Cause: Overall hardness increases after film + substrate lamination
Solution: Select 12 μm film (vs 25 μm)
Issue 2: Ink color fades after lamination
Cause: Optical refraction of the film alters the visual color
Solution: Reserve +10% color compensation before printing
Issue 3: Lamination bubbling
Cause: Mismatched laminating temperature/pressure
Solution: Adjust laminator temperature to 100-120℃ + pressure to 0.5-1 kg/cm²

FAQ
What is the difference between glossy lamination and matte lamination for labels?
3 Differences: (1) Visual—Glossy film produces specular reflection (high-brightness sheen), matte film produces diffuse reflection (soft sheen); (2) Tactile—Glossy film is smooth, matte film has a fine sand-textured finish; (3) Application—Glossy film suits fast-moving consumer goods (attracting attention from a distance), matte film suits mid-to-high-end products (tactile experience at close range). Cost is the same (+0.05–0.1 RMB/sheet), but the visual difference is significant.
What are the functions of label lamination?
Three core functions: (1) Waterproof—the label becomes water-resistant after lamination (synthetic paper also requires lamination to be waterproof); (2) Tear-resistant—PET film + substrate = tear strength doubled; (3) UV-resistant—ink does not fade after lamination (long-term exposure testing can be improved by 2-3 times). Lamination is strongly recommended for high-value, outdoor, or long-term use labels.
What film is used for label lamination?
Three mainstream lamination films: (1) BOPP film – biaxially oriented polypropylene (low cost, 0.5 RMB/sheet), most commonly used; (2) PET film – polyester film (high-temperature resistance + high strength, 1 RMB/sheet), suitable for electronics/industrial use; (3) Laser film – rainbow holographic film (2-3 RMB/sheet), for high-end gift boxes. All three film thicknesses range from 12-25 μm, with thicker films offering greater durability.
Will the label laminate/lamination peel off?
Yes, film peeling occurs in three situations: (1) adhesive mismatch — BOPP film is incompatible with water-based adhesive (solvent-based adhesive must be used); (2) surface oil contamination — surface not wiped clean before laminating (insufficient contact between film and substrate); (3) high-temperature environment — film glass transition temperature is lower than the service temperature (film deforms and detaches). Improvement strategies: select a dedicated laminating adhesive + clean the surface before laminating + select a temperature-resistant film (PET film withstands 150 °C).
Does the label lamination affect barcode scanning?
Impact. Three causes: (1) specular reflection — the bright film strongly reflects light, causing the scanner's laser to be reflected away (cannot scan); (2) smooth surface — the film is too smooth, causing the scanner's camera to fail to focus; (3) increased thickness — film thickness increases by 0.02 mm, lowering the QR code error correction rate. Recommendation: choose matte film for labels with QR codes (does not affect scanning); bright film can be freely chosen for labels without QR codes.
