What are the different materials that self-adhesive labels can be applied to?

Pressure-sensitive labels can be applied to a wide range of materials, covering most common materials found in everyday and industrial settings.  They can be categorized into the following major types based on surface characteristics:

Smooth, Hard Materials

These materials have a flat, dense surface and are the easiest for pressure-sensitive labels to adhere to. Ordinary adhesives provide a strong bond.

Glass: Glass bottles, glass jars, glass panels, mirrors.

Metals: Aluminum cans, tin cans, stainless steel products, aluminum alloy profiles, metal nameplates.

Plastics: PET bottles, PVC boxes, acrylic sheets, ABS plastic parts, PS packaging boxes.

Paper Products: Coated paper packaging boxes, laminated cardboard boxes, hardcover book covers.

Rough, Porous Materials

These materials have uneven or porous surfaces, which can trap air.  Stronger adhesives with a slightly thicker adhesive layer (such as hot-melt adhesive) are needed to fill the gaps and improve adhesion.

Paper Products: Ordinary cardboard boxes, kraft paper, corrugated cardboard, paperboard, woven paper bags.

Wood: Solid wood boards, plywood, MDF, wooden furniture, wooden crafts.

Other: Cement walls, gypsum board, rough ceramic products.

Low Surface Energy Materials

These materials have low surface tension, making it difficult for ordinary adhesives to adhere.  Special low-surface-energy adhesives are required for pressure-sensitive labels.

Plastics: PE (polyethylene) films/containers, PP (polypropylene) boxes/pipes, silicone products, fluoroplastic parts.

Special Coatings: Teflon-coated surfaces, anti-fingerprint coated panels, some matte plastic surfaces.

Flexible, Elastic Materials

These materials are easily stretched and deformed, requiring labels with good flexibility to prevent curling and detachment.

Soft Plastics: PVC soft films, PE soft bags, rubber products, latex gloves.

Textiles: Non-woven fabrics, canvas bags, polyester fabrics, nylon products.
