Product Overview

photobank (24)

Small-format packaging is precision work. When you're wrapping a 20 g chocolate bar or a bite-sized candy piece, every millimeter of film alignment matters. A 2 mm misregistration on a standard chocolate bar might be barely noticeable — on a mini bar, it's a visibly off-center product that retailers reject and consumers ignore.

The Junyao compact horizontal pillow wrapping machine is calibrated specifically for small-format confectionery and snack products. The servo-driven film feed delivers ±0.5 mm positioning accuracy. The photoelectric registration system compensates for film stretch and speed variations in real time. And the temperature-controlled sealing system is tuned for the thin films and short dwell times that small-format packaging demands.

Key Features

1. High-precision film registration for small packages. ±0.5 mm accuracy via high-resolution servo feed with photoelectric eye-mark detection. Drop a 2 mm misalignment on a 50 mm bag and you've lost 4% of your printable area — this machine prevents that.

2. Compact footprint. Designed to integrate into lines where floor space is at a premium. No facility modifications required.

3. Temperature control for chocolate surface protection. PID-controlled jaws prevent heat transfer to chocolate products. Optional cooling air nozzles for ultra-thin films and heat-sensitive coatings.

4. Quick format changes. Recipe-based parameter recall. Switch between product sizes in under 5 minutes.

5. Food-grade 304 stainless steel. All product contact surfaces. CE certified.

Applications

Chocolate Bars and Blocks: Solid chocolate bars — from plain dark chocolate to milk chocolate with inclusions (nuts, fruit, crisps) — are the JY-L1000's core application.
Filled and Decorated Chocolate Products: Liquid-filled chocolate bars, praline-filled tablets, and chocolate products with surface decorations (drizzled contrasting chocolate, sprinkled toppings, embossed logos) are among the most challenging items to package automatically.
Protein Bars, Energy Bars, and Nutrition Bars: The protein bar category has grown rapidly across global markets, bringing with it specific packaging requirements. Protein bars typically have surface coatings (chocolate, yogurt, or compound) that are prone to melt marking, and the bars themselves can exhibit dimensional variability due to variations in ingredient mixing and forming. The
Coated Snack and Cereal Bars: Muesli bars, granola bars, and cereal bars with chocolate or yogurt bases share the same thermal sensitivity as pure chocolate products but add the complexity of particulate ingredients that can detach and contaminate the sealing area.

Manufacturing and Quality Assurance

JY-L1000 production at Xingjunyao's Taizhou facility follows a rigorous quality protocol that reflects the machine's specialization in premium product packaging. Incoming servo motors are tested on a dynamometer to verify torque-speed curves and encoder resolution before acceptance. Sealing jaw assemblies undergo a thermal imaging validation step where an infrared camera maps the temperature distribution across each jaw face, confirming that the heated sealing land reaches uniform temperature (±1°C across the entire land surface) — a critical requirement for consistent seal quality. The nitrogen flush gas path is pressure-tested at 200% of maximum operating pressure to verify leak-tight integrity of all fittings, tubing, and the injection port assembly.
