The PE Film Sleeve Packaging Line for Bottles is an integrated, automated system designed for high‑efficiency bottle wrapping and bundling using polyethylene shrink film. It is commonly applied in the beverage, dairy, edible oil, chemical, and household product industries, where reliable, protective, and visually appealing secondary packaging is essential.The line typically begins with an infeed conveyor that channels bottles from upstream production or filling equipment. Bottles can be fed in single or multiple lanes, and adjustable guide rails allow quick format changes for different bottle diameters and heights. An automatic bottle sorting and collating unit arranges products into the required group configurations, such as 2x2, 3x2, 4x3, or customized patterns, depending on transport and retail requirements.Once the desired matrix is formed, the grouped bottles are transferred to the film wrapping section. A roll of polyethylene shrink film is unwound and accurately tensioned by a film feeding mechanism. The system uses sensors to detect pack length and position, ensuring precise cutting and minimal film waste. The film is then wrapped around the bottle group, overlapping on the underside or side to form a sleeve. According to production needs, the line can operate in full‑wrap or sleeve‑only modes, with or without supporting cardboard trays or pads.The wrapped pack moves into a shrink tunnel, which is the core component of the line. Inside the heated tunnel, controlled hot air circulates around the product, evenly shrinking the film to form a tight, stable bundle. Temperature, air flow, and conveyor speed are adjustable via a central control panel to accommodate different film thicknesses, bottle shapes, and packaging specifications. Properly controlled shrinking results in a smooth, wrinkle‑free finish that enhances product appearance while ensuring sufficient holding force for transport and handling.Downstream, a cooling section or ambient conveyor allows the film to set, improving bundle rigidity. Finished packs are then automatically transferred to accumulation tables or directly to palletizing systems. The line can be integrated with labeling, coding, or inspection devices, such as print‑and‑apply labelers, inkjet coders, barcode scanners, and weight or vision inspection systems.The entire system is typically governed by a programmable logic controller with a user‑friendly touch screen interface. Operators can store multiple product recipes, adjust parameters, and monitor alarms in real time. Safety features, including emergency stops, protective guards, and interlocks, are incorporated throughout. Designed for hygienic environments, the structure usually employs stainless steel or coated steel, with accessible components for quick cleaning and maintenance. Overall, the PE Film Sleeve Packaging Line for Bottles delivers consistent packaging quality, reduced labor costs, and increased production flexibility.
