Types of self-adhesive labels

Self-adhesive labels are widely used in various industries due to their convenience and flexibility. They come in various types based on different parameters such as materials, adhesiveness, application environments, and functions.

1. Classification by Material

1.1 Paper Labels: These are the most common type of labels, suitable for disposable products or packaging. They are cost-effective and suitable for one-time or short-term use.

1.2 Plastic Labels: These are more durable than paper labels and have good waterproof properties. They are made from materials like PE, PP, PET, etc. They are commonly used where long-term use or harsh environmental conditions are expected, such as cosmetics and cleaning supplies.

1.3 Metal Foil Labels: These provide higher durability and waterproof properties, making them suitable for more challenging environments, such as automotive parts and electronic devices.

2. Classification by Adhesiveness

2.1 Permanent Labels: These labels have strong adhesiveness and are difficult to remove once affixed. They are usually used for product identification and safety warnings.

2.2 Removable Labels: These labels have moderate adhesiveness and can be easily torn off without leaving traces on the product surface. They are commonly used for promotions and price tags.

2.3 Repositionable Labels: These labels have a certain level of adhesiveness and can be repeatedly affixed. They are commonly used for toys and teaching aids.

3. Classification by Application Environment

3.1 High-temperature Labels: These labels can withstand high-temperature environments, such as machinery and baked food packaging.

3.2 Low-temperature Labels: These labels can be used in low-temperature environments without losing their adhesiveness due to the cold. They are typically used in frozen food packaging.

3.3 Waterproof Labels: These labels can resist moisture and humidity, making them suitable for bathroom supplies and swimming pool equipment.

3.4 Oil-resistant Labels: These labels can resist grease and oil stains, making them suitable for kitchen utensils and mechanical equipment.

4. Classification by Function

4.1 Information Labels: These labels are used to display product information, such as ingredients, production date, expiration date, and usage instructions.

4.2 Price Tags: These labels are used to display the selling price of goods.

4.3 Marketing Labels: These labels are used for promotional activities, such as discounts and buy one get one free offers.

4.4 Warning Labels: These labels are used to indicate danger, warnings, or precautions.

4.5 Logistics Labels: These labels are used to identify, track, and manage goods, including address labels, barcode labels, and RFID labels.

4.6 Certification Labels: These labels are used for product quality certification, origin certification, etc. Examples include ISO quality certification labels and organic food certification labels.

4.7 Security Labels: These labels are used to prevent products from being illegally opened or tampered with. Examples include anti-counterfeit labels and tamper-evident labels.

5. Classification by Printing Method

5.1 Flexographic Printing Labels: These labels are suitable for large-scale production, with a stable printing effect and rich colors.

5.2 Digital Printing Labels: These labels are suitable for small batch, diversified, personalized production needs, offering fast printing speed and high efficiency.

5.3 Thermal Transfer Labels: These labels use heat to transfer pigments from the ribbon onto paper or plastic labels. They are suitable for printing fine patterns such as barcodes and QR codes.

5.4 Thermal Printing Labels: These labels use thermal paper as the label material and pigment is fixed on the label by heat, making them suitable for applications like supermarket price labels and weighing labels.

The aforementioned categories offer a more detailed classification of self-adhesive labels. These categories are not mutually exclusive and can often overlap based on the specific requirements of a given application. Therefore, a label could simultaneously be a high-temperature label, a permanent label, and an information label. The flexibility in combining these categories allows for a wide range of label design and usage scenarios, making self-adhesive labels a versatile tool across various industries.
