Packaging

Publish Time: 2025-05-30     Origin: Site

In the packaging industry, woven bags and other flexible materials require stringent metal contaminant control - their end-use applications are unpredictable, ranging from food and pharmaceutical to industrial chemicals.


Primary Sources of Metal Contamination:

1.Raw material impurities: Polypropylene pellets or recycled plastics may contain metal shavings, screws, or wire fragments from processing equipment wear.

2.Production-line hazards: Degraded parts from extruders or looms (e.g., bearing debris, broken needles) contaminating woven fabric.


Consequences of Undetected Metal:

Product integrity: Metal in food/medical-grading packaging (e.g., flour or fertilizer bags) may taint contents, triggering consumer lawsuits or recalls.

Customer penalties: Contaminants jamming client’s filling lines, resulting in breach-of-contact claims.

Reputational damage: Viral complaints on social media eroding brand equity.


Our solution: End-to-end metal detection systems to cut quality risks, reduce liability costs, and secure your market position.


In the packaging industry, automated checkweighers play a critical role in manufacturing cartons, corrugated boxes, and food pouches by delivering:


1.Cost & Material Optimization

Ensures per-unit weight accuracy, avoiding overages (excessive freight costs) or underweight (non-compliance penalties).

Monitors paper grammage to prevent underfilling (quality risks) or overfilling (material waste).


2.Production Process Control

Detects real-time anomalies like excessive glue application or moisture-affected board weight, enabling immediate corrections.


3.Quantity Assurance

Verifies multi-piece bundles (e.g., bags per bag) to eliminate missing/extra items, ensuring compliance with labeling.


We have multiple models of checkweighers available.
