Square Bottle OPP Labeling Machine

The Packsoul Square Bottle OPP Labeling Machine is an automated hot-melt labeling system for square/rectangular containers. Servo positioning locks onto bottle edges to ensure flat label application on all surfaces. It supports high-speed, large-volume production for square bottles in water, personal care, and daily chemical sectors, and integrates seamlessly with complete filling lines.

Product Features

1. Rotary mechanism independently controlled by servo motors, precisely adjusting bottle angle to match label placement with product artwork orientation.
2. High-precision label mark sensor detects registration marks in real time, ensuring accurate label dispensing and minimizing misalignment—delivering stable cutting and application even at high speeds

3.Fully automatic operation with VFD speed adjustment based on the bottle feeding rate. The default settings of the Packsoul Square Bottle OPP Labeling Machine prevent label dispensing when no bottle is detected and stop glue application when no label is present.

4.An in-house glue tank provides stable adhesive output through a dedicated pump, with filtration and adhesive recovery to reduce material loss. Built-in temperature control up to 180°C maintains consistent glue viscosity under different ambient conditions.

5.Dual cutters perform pre-cutting before labels are transferred to the pre-labeling position by a vacuum drum. A brush assembly then smooths the labels onto the bottles, while the transfer system maintains label height accuracy within ±1 mm.

FAQ

Q1: What bottle shapes are suitable for this machine?

A: It handles square and rectangular PET, HDPE, and glass containers, including water, edible oil, and daily chemical bottles.

Q2: How is consistent label orientation ensured for square bottles?

A: An independent servo rotation mechanism and color mark sensors detect labels and precisely adjust the bottle angle, ensuring accurate pattern alignment at the corners.

Q3: Will labels peel off at the corners during high-speed production?

A: No. A vacuum transfer drum and brush-pressing mechanism ensure smooth wrapping on flat surfaces and corners. The label height is controlled within ±1mm, significantly reducing peeling and wrinkling.

Q4: Does it have a "no bottle, no label" safety feature?

A: Yes. The fully automatic system features "no bottle, no label" and "no label, no glue" logic. The inverter auto-adjusts speed based on bottle flow to minimize waste and faults.

Q5: What are the advantages of the hot melt glue system? Is glue consumption high?

A: Our proprietary glue box with a dedicated pump ensures stable, precise application and features a filter recovery system. With precise temperature control (up to 180°C), it maintains optimal viscosity in cold environments and minimizes glue consumption.
