Sleeve Labeling
Structural schematic diagram of the sleeve labeling structure

In the bottled water industry, sleeve labeling has become essential for product identification and marketing. Sleeve labeling involves the application of a heat-shrinkable plastic film sleeve to the body of a filled bottle, which conforms to the shape of the bottle upon heating. The sleeve label provides a 360-degree surface area for product branding, nutritional information, and other relevant details.

Sleeve labeling structures for bottled water filling production lines typically consist of a frame, conveying chain, sleeve label stop plate, brushing device, and label feeding wheel. The conveying chain transports the filled bottles to the labeling area, where the sleeve label is applied to the bottle. The sleeve label stop plate holds the sleeve label in place during the labeling process, while the brushing device ensures that the label is applied smoothly and evenly. The label feeding wheel delivers the label to the appropriate position on the bottle.

The importance of sleeve labeling in ensuring product quality and reducing production costs cannot be overstated. Sleeve labeling allows for greater flexibility in packaging design and branding, which can enhance product appeal and increase sales. Additionally, sleeve labeling provides a more durable and moisture-resistant label compared to traditional pressure-sensitive labels, which can become damaged or fall off during transportation and storage.

According to industry data, the global demand for sleeve labeling is expected to grow at a CAGR of 5.2% from 2020 to 2027, driven by factors such as increasing demand for packaged foods and beverages, growing consumer awareness about product safety and authenticity,and the need for efficient and cost-effective labeling solutions in the manufacturing industry. In the bottled water industry specifically, sleeve labeling has become increasingly popular due to its ability to enhance product differentiation and brand recognition.

However, sleeve labeling also presents certain challenges, particularly concerning label height variation in different filling bottles. Some companies use filling bottles with label heights as low as 27mm, which can lead to label deviation and misalignment during the labeling process, resulting in poor product appearance and reduced product quality. Therefore, it is essential to have a sleeve labeling structure that can accommodate label heights within a specific range and ensure smooth and accurate sleeve labeling.

In summary, sleeve labeling structures for bottled water filling production lines are crucial in ensuring product quality and reducing production costs. Sleeve labeling provides a more durable and moisture-resistant label than traditional pressure-sensitive labels, enhancing product appeal and increasing sales. However, label height variation poses a significant challenge in sleeve labeling, requiring an optimized sleeve labeling structure to accommodate label heights within a specific range.

Common Challenges in Sleeve Labeling for Bottled Water Filling Production Lines

Sleeve labeling for bottled water filling production lines can pose certain challenges that affect the quality and efficiency of the labeling process. The following are some of the most common difficulties in sleeve labeling and how they can be addressed:

Label Height Variation

  • The label height of a filling bottle can range from 25mm to 70mm, depending on the bottle size and shape.
  • Label deviation can occur when the label is not applied correctly on the bottle, resulting in poor product appearance and reduced product quality.
  • To address this challenge, sleeve labeling structures should be designed to accommodate label heights within a specific range. The sleeve label stop plate can be adjusted to the appropriate height for the label being used, ensuring that the label is held in place during the labeling process.

Label Deviation

  • Label deviation can occur when the label is not properly aligned with the bottle during application, resulting in a crooked or misaligned label.
  • This can also result in a label that needs to be tight enough, which can affect the appearance and quality of the final product.
  • To address label deviation, sleeve labeling structures should be designed to ensure the label is correctly aligned with the bottle during application. The stop plate should be positioned at the correct height, while the label feeding wheel should be adjusted to deliver the label to the correct position on the bottle. The brushing device can also ensure that the label is applied smoothly and evenly, reducing the risk of misalignment or skewing.

Misalignment and Skewing of Labels During Thermal Shrinkage

  • After the sleeve label is applied to the bottle, the bottle is subjected to thermal shrinkage, where the label is heated and shrinks to conform to the shape of the bottle.
  • If the label is not properly aligned with the bottle, it can become misaligned or skewed during thermal shrinkage, resulting in an uneven or distorted label.
  • To address this challenge, sleeve labeling structures should be designed to ensure the label is properly aligned with the bottle before thermal shrinkage. Additionally, the sleeve label stop plate and the brushing device should be used to apply the label smoothly and evenly, reducing the risk of misalignment or skewing during thermal shrinkage.

Label Wrinkling and Bubbling

  • Sleeve labels can wrinkle or bubble during application, resulting in an uneven or unappealing label.
  • This can be caused by a variety of factors, such as improper label tension, uneven heating during thermal shrinkage, or poor label quality.
  • To address this challenge, sleeve labeling structures should be designed to ensure that the label is applied with the appropriate tension and that the heating process is even. Additionally, high-quality labels should be used to reduce the risk of wrinkling or bubbling.

Labeling Speed and Efficiency

  • The speed and efficiency of sleeve labeling can affect production output and cost-effectiveness.
  • Slow labeling speeds or frequent equipment downtime can decrease productivity and production costs.
  • To address this challenge, sleeve labeling structures should be designed to optimize labeling speeds while ensuring accuracy and consistency. Regular maintenance and equipment cleaning can also reduce the risk of equipment downtime and increase efficiency.
