Self-adhesive labels, also known as sticker labels, are made up of face-stock + adhesive layer + release liner. Although they look simple, the choice of structure and materials can directly affect the label’s appearance, stickiness, durability, and application results.

1. Face-stock

This is the top layer of the label where the printing is applied. Common facestock types include:

• Paper-based: Coated paper, writable paper — economical and suitable for food, daily goods, and general applications.

• Synthetic: PET, PP, PE — waterproof, oil-resistant, tear-resistant; perfect for cosmetics, beverages, and frozen foods.

• Specialty: Metallic paper, holographic film, thermal paper — for unique visual effects or specific functions.

2. Adhesive Layer

The adhesive determines stickiness and suitability for different environments:

• Permanent Adhesive: Strong bond, not easily removed — for long-term use.

• Removable Adhesive: Peels off cleanly without residue — ideal for price tags, temporary labels.

• Freezer Adhesive: Maintains adhesion in low temperatures — for cold chain labels.

3. Release Liner

Protects the adhesive layer and allows easy application, especially in automatic labeling machines. Common materials include glassine paper and PET film.

4. Material Selection Tips

• High temperature: Heat-resistant synthetic face-stock + high-temp adhesive.

• Moist environments: Waterproof synthetic face-stock + strong waterproof adhesive.

• Frozen products: Low-temperature face-stock + freezer adhesive.

Tip: A good label is not just about printing quality — material and adhesive compatibility are equally important. The right selection can extend label lifespan and enhance brand image.
