- Paper-Based Round Stickers
Paper is the most basic material for round stickers, featuring low cost and high printing adaptability. It is suitable for short-term, indoor use and can be divided into the following types:
Coated Paper Stickers:
The surface is coated for smoothness and high whiteness, enabling vivid colors and sharp patterns. It is a common material for decorative stickers—for example, cartoon round stickers in planners or festive decorative stickers. However, its drawbacks are clear: it is not waterproof, tears easily, and may yellow over time when exposed to air. Typically used for disposable or short-term scenarios such as party invitation decorations or gift wrapping embellishments.
Kraft Paper Stickers:
Made from kraft paper with a natural, vintage texture, usually in yellow-brown or dark brown shades, ideal for creating a rustic, organic look. Commonly used for cultural and creative product labels (e.g., “handmade” tags for artisan food) or storage box labels. While kraft paper has certain toughness, it is not waterproof, and its print color saturation is low—best paired with black or dark text to highlight a simple, natural aesthetic.
Glassine Paper Stickers:
Lightweight, semi-transparent, with a frosted, hazy effect. Printed patterns appear soft with a “subtle transparency.” Often used for layered decorative effects in planners (e.g., over photos or text) or fine detailing on wedding invitations. However, they have low strength, tear easily, and are not moisture-resistant—contact with water will soften and deform them.
- Plastic-Based Round Stickers
Plastic materials, with their waterproof and wear-resistant properties, are ideal for outdoor and high-frequency use. Common types include:
PVC Stickers:
Made from polyvinyl chloride, offering excellent waterproofing and flexibility, allowing them to conform to curved surfaces (e.g., water bottles, car bodies). They are resistant to acids and alkalis and do not fade easily. Surface finishes include glossy PVC (reflective, decorative) and matte PVC (soft texture, suitable for labeling). Often used for outdoor round decals or warning labels for bathroom products. However, standard PVC may release harmful substances at high temperatures and is unsuitable for direct food contact.
PET Stickers:
Made from polyethylene terephthalate, with higher hardness, good flatness, and excellent resistance to extreme temperatures (-40°C to 120°C). They are eco-friendly and non-toxic, making them suitable for food packaging and electronics. Examples include round brand labels on bottled water or stickers on microwave-safe containers. PET offers high color reproduction but less flexibility, making it unsuitable for highly curved surfaces.
OPP Stickers:
Made from oriented polypropylene, featuring high transparency (glass-like appearance), moisture resistance, and tear resistance, often called “crystal stickers.” Suitable for applications where the underlying surface needs to remain visible, such as round “Push/Pull” signs on glass doors or decorative labels on cosmetic bottles. The drawback is relatively weak adhesion, which may cause detachment in humid environments.
- Special-Function Round Stickers
To meet specific needs, round stickers are available in various functional materials that address waterproofing, heat resistance, removability, and more:
Waterproof Adhesive Stickers:
Made from synthetic paper (e.g., polyethylene synthetic paper) with a waterproof film coating, combining the print adaptability of paper with the waterproof properties of plastic. Common in outdoor signage (e.g., round park markers) and kitchen product labels (e.g., fridge magnets, spice jar labels). They remain clear and adhesive even after repeated contact with water or grease.
Removable Stickers:
Use low-tack adhesives, allowing easy removal without residue, ideal for temporary use. Examples include temporary exhibition signs, seasonal wall decals (e.g., Christmas stickers), and interchangeable decals for children’s toys. Often made from PVC or PET for durability and easy removal.
Metallic Stickers:
Base material is coated with a metallic film (e.g., aluminum foil, copper foil) to achieve gold, silver, or brushed metal effects, adding texture and a premium feel. Common for gift packaging seals or brand logo displays on premium goods. The main drawback is susceptibility to scratches, requiring protection from frequent friction.
Fluorescent / Glow-in-the-Dark Stickers:
Contain fluorescent pigments or phosphorescent powder, glowing in the dark or emitting light after exposure. Suitable for nighttime visibility needs, such as round fire exit markers or starry-sky decals for children’s rooms. Typically made from PVC to ensure stable pigment adhesion and some waterproofing.
- Eco-Friendly and Premium Round Stickers
With the rise of environmental awareness and high-end customization, the following materials are gaining popularity:
Plant-Based Biodegradable Stickers:
Made from renewable materials such as corn starch or bamboo fiber, paired with biodegradable adhesives. They decompose naturally after disposal, reducing environmental impact. Suitable for food packaging (e.g., organic food certification labels) or eco-themed promotional events. However, they have lower durability, are not waterproof, and are unsuitable for high-temperature applications, resulting in a shorter lifespan.
