Square Plastic Water Bottles Half-Label Shrink Sleeve Applicator

Half-labeling on square bottles refers to a packaging method where the label only covers the middle or front half of the square bottle, not the entire bottle. For this type of packaging, the shrink sleeve labeling machine needs to be specially designed to ensure precise label positioning and uniform shrinkage on the bottle.

Key technical points:
1. Bottle Positioning and Locking
• Precise Clamping: Due to the square shape of the bottle, which has four flat surfaces, there is a higher chance of tilting or shifting. Therefore, an effective clamping system is required to ensure the bottle remains stable during labeling and only locks the front half of the bottle.
2. Label Feeding and Positioning
• Precise Label Feeding: The label feeding system needs to precisely control the entry position of the label, ensuring it only covers the front half of the bottle and perfectly aligns with the bottle’s design (front, sides, and back).
3. Shrinkage Process Control
• Shrink Tunnel Control: During the steam shrinkage process, the temperature, pressure, and steam nozzle angle need to be precisely controlled to ensure the label shrinks evenly on the front half of the bottle, preventing the label from shifting or stretching at the bottom or top of the bottle.
4. Locking Area Control
• Since only the front half of the bottle needs to be locked, the labeling machine must ensure that the label stays in the preset position during the shrinkage process and does not shift or misalign, especially as the bottle shape may change during shrinking.


Half-labeling on square bottles requires special attention to bottle stability and label positioning. Through precise bottle clamping, label feeding control, and accurate shrinkage process regulation, the XINHUA shrink sleeve applicator machine ensures that the label is accurately applied to the front half of the square plastic water bottles, achieving an efficient and precise labeling result.
