1. Pre-made Pouch Packaging and Inspection Line

• Core Function: Automated packaging and inspection for pre-made pouches, achieving a full process of "pouch picking → opening → filling → sealing → inspection."
• Equipment Composition: Elevator conveyor (feeding), rotary pouch feeding mechanism (automatic picking and opening), packaging host (material filling, sealing), inspection unit (weight check, metal detection, vision inspection, etc.).
• Working Characteristics: Strong adaptability to pre-made pouches (supports different specifications), high degree of automation, suitable for granular and block materials (such as nuts, frozen foods, dried goods).
• Application Scenarios: Snack foods, frozen foods, condiments, etc., focusing on efficiency and quality control for batch packaging of pre-made pouches.

2. Modified Atmosphere Packaging (MAP) Inspection Line

• Core Function: Adjusts the internal atmosphere by gas replacement (e.g., filling with N₂, CO₂) to extend shelf life, while synchronously completing inspection.
• Equipment Composition: MAP machine (gas mixing system, vacuum/inflating chamber, sealing device), conveyor line, weight check, metal detection, leak testing (optional).
• Working Characteristics: Precise control of gas ratios (e.g., low-oxygen formulations for fresh meat), inhibits microbial growth, maintains product color and taste.
• Application Scenarios: Short-shelf-life products requiring freshness (fresh meat, cooked food, fruits & vegetables, salads), solving the integration of "freshness preservation + inspection."

3. Pillow Packaging Inspection Line

• Core Function: Wraps products into a "pillow" shape (horizontal rectangular), suitable for regular-shaped items, while synchronously inspecting quality.
• Equipment Composition: Pillow packaging machine (film former, horizontal/vertical sealing and cutting device), product arranging conveyor, inspection unit (weight check, metal detection, coding/appearance inspection).
• Working Characteristics: Neat package shape, high speed (suitable for high-speed lines), high film utilization, supports heat shrink film, composite film, etc.
• Application Scenarios: Regular-shaped products like biscuits, instant noodles, daily necessities, and pharmaceuticals, focusing on standardized packaging and efficient inspection.

4. Cling Film Packaging Inspection Line

• Core Function: Wraps products with cling film (stretch film) for simple preservation and appearance protection, while synchronously detecting defects.
• Equipment Composition: Cling film packaging machine (film stretching mechanism, wrapping/sealing device), conveyor line, inspection unit (appearance inspection, weight check, metal detection).
• Working Characteristics: Flexible packaging (adapts to different sizes), low cost, retains product visibility, suitable for scenarios with manual-assisted feeding.
• Application scenarios: Fresh fruits and vegetables, baked products, cooked food, etc.Products that require easy preservation and display appearance, focus on Fast wrapping + basic inspection.

Commonalities and Differences

• Commonalities: All integrate a conveyor system and inspection modules (weight and metal detection as standard), ensuring product safety and compliance.
• Differences: Different core packaging technologies (pre-made pouch, MAP, pillow forming, cling film wrapping), corresponding to differences in product form, preservation needs, and packaging efficiency.
