1. What Are PVC ?

Polyvinyl chloride, abbreviated as PVC, is widely used in “soft rubber badges” (also called micro-injection molded emblems).

PVC patches are ubiquitous in daily life, though often overlooked. Examples include:

Logo tags on sports shoes, slippers, bags, and outdoor apparel
Luggage tags, keychains, phone charms, and other accessories
Coasters, car mats, shoe soles, and even cycling gear

While some international clients refer to PVC patches as “rubber badges,” genuine rubber is rarely used in the label industry due to higher costs and technical limitations. PVC and silicone dominate this market.

Today, PVC remains the mainstream material for soft rubber labels thanks to its:

Vibrant color options
Cost-effectiveness (compared to silicone)
Versatility in creating unique, colorful designs

2. Features of PVC Patches

Material: Soft PVC (waterproof, wear-resistant, flexible)
Techniques: Mold-cast with embossed (raised) or debossed (indented) effects
Applications: Clothing/backpack badges, brand logos, military/tactical gear, fashion accessories

3. Raw Materials for PVC Production

DINP oil (plasticizer)
PVC powder (e.g., Korean or Hunan-sourced)
Stabilizers
Color pigments
UV inhibitors
Glow-in-the-dark powder
Fragrance additives (optional)

4. PVC Manufacturing Tools (Partial Display)

(Note: This section would typically include images of tools like injection molds, mixing machines, etc.)

5. Factory Mass Production Process

Step 1: Design Preparation

Vector files: Use Illustrator/CorelDRAW (AI/EPS formats) with clean outlines.
Color separation: Specify Pantone codes (usually 1-3 colors).
Special effects:
3D embossing: Layer designs for raised areas.
Metallic/glow-in-the-dark: Requires specialty PVC compounds.

Step 2: Mold Creation

Copper mold engraving: Custom-made based on design (cost: ¥500–2000, varies by complexity).
Prototyping: Factory produces samples for approval.

Step 3: Production

Material mixing: PVC base + plasticizers + colorants.
Injection/compression molding: Molten PVC is pressed into molds under high pressure.
Trimming & QC: Excess material removal and defect inspection.
