Candles are commonly used items in people’s daily lives. The label on a candle serves as both its decoration and instruction manual. Deciding what kind of candle sticker to use and how to attract consumers’ attention require careful design.
Coated Paper
Characteristics: It is made by coating a white slurry on the base paper and then super – calendering it. The surface is smooth and flat, with good ink – absorption properties, which can transfer the ink to the paper surface with the least amount of diffusion. Its whiteness can reach over 90%, presenting rich color levels and fine image details. Coated paper is very commonly used and highly adaptable, so many industries can use it for stickers. Moreover, this kind of paper is durable, which can prolong the service life of stickers.
Advantages: It can print vivid and highly – saturated colors, with clear and realistic patterns, which can well show the delicate sense of design and enhance the overall appearance and quality of candles. The paper has good stiffness and is not easy to wrinkle or deform during transportation or storage. It is easy to paste and can maintain a good appearance. Its bright texture will attract many customers.
Disadvantages: Although it has certain heat resistance, in the high – temperature environment generated by the long – time burning of candles, especially around some candles without wind – proof covers, the edges may curl and the paper may change color. In addition, its waterproof performance is average. If the candle is used in a humid environment or splashed with water, the sticker may be damaged.
Applicable Scenarios: It is widely used in various high – end gift candles, decorative candles, and candles used in indoor environments. These scenarios usually have high requirements for the visual effect of stickers, and the temperature and humidity are relatively stable. Since the temperature of the candle is high during combustion, the sticker is required to have high toughness so that the candle label can be well preserved when the candle is burning.
Thermal Paper
Characteristics: A thermal – sensitive coating (thermal – sensitive color – changing layer) is coated on ordinary paper, mainly composed of colorless dyes, developers, and sensitizers. When the thermal – sensitive paper meets the heated print head, the colorless dye in the coating reacts chemically with the developer to change color, thus forming patterns or text. It is soft in texture and can closely adhere to the curved surface of the candle.
Advantages: It is convenient to print. It does not require ink cartridges or ink and can be quickly printed through a thermal printer, reducing the printing cost and equipment maintenance cost. For some candles that need to frequently change the sticker content or are produced in small batches, thermal paper has high flexibility and economy. Thermal paper is the kind of paper used to print prices in supermarkets.
Disadvantages: The content printed on thermal paper has a limited storage time. When exposed to light, high temperature, or high humidity for a long time, it is easy to fade, resulting in blurred sticker information. Moreover, its viscosity is usually weak, and its adhesion to the candle surface is poor. Especially when the candle expands due to heat or wax oil seeps out, the sticker is easy to fall off.
Applicable Scenarios: It is suitable for disposable candles, such as emergency candles in hotel rooms and short – term promotional candles in restaurants. It is also often used in some occasions where the sticker cost is sensitive and the use cycle is short. For candle stickers, thermal paper has strong heat resistance during the combustion of candles, so this kind of paper is very suitable for packaging candles.
PET Film
Characteristics: It is made of polyethylene terephthalate and is a colorless, transparent, and glossy film. It has high strength and toughness, is not easy to tear and break, and can withstand a certain degree of stretching and twisting. It has excellent heat resistance, can maintain stable physical properties at high temperatures, and has good waterproof, moisture – proof, and chemical – corrosion – resistant properties. This PET film has many advantages. It is very wear – resistant and durable, suitable for use on the surface of candle stickers.
Advantages: Due to its high transparency, when pasted on the candle, it can maximize the display of the candle’s own color, texture, and shape. At the same time, through the patterns and text printed on the film, it can play a decorative and marking role, increasing the product’s attractiveness. Its excellent heat resistance and durability ensure that the sticker remains intact during the candle burning process and long – term storage, and is not prone to problems such as deformation, fading, or falling off.
Disadvantages: The surface of the PET film is smooth, and its adhesion to the ink is poor. Special processing techniques and inks are required for high – quality printing, which increases the printing cost and difficulty. Moreover, compared with other paper materials, the cost of PET film is higher, which will increase the production cost of candles.
Applicable Scenarios: It is often used for high – end scented candles, boutique candles, and other candle products with extremely high requirements for product quality and appearance. These candles are usually displayed and used in various environments and require stickers to have good weather resistance and decoration.
Kraft Paper
Characteristics: It is made from sulfate softwood pulp through processes such as beating, sizing, and drying. The paper is tan – colored, tough in texture, has a certain tear – resistance strength and water – resistance, and has a natural texture on the surface, giving people a rustic and retro feeling.
Advantages: It has good environmental performance, meeting the modern pursuit of green and sustainable products. It is suitable for candles that focus on the concept of natural and organic. Its heat – resistance is good, which can withstand a certain amount of heat generated by the burning of candles and is not easy to burn or damage quickly. The texture and color of kraft paper can add a unique texture to the candle, creating a warm and natural atmosphere.
