Buying Guide
- Filling range and accuracy: Choose a model that covers your target pouch volumes (common range: 50-500 ml) and maintains around ±1% accuracy to minimize waste.
- Sealing method compatibility: Decide between side/back sealing or three-side sealing. Some lines offer multiple options; pick the one that matches your pouch design and film material.
- Throughput needs: Estimate weekly production volume. If your line demands 1,000+ bags/hour, prioritize machines billed for high-speed operation and stable performance.
- Power and electrical requirements: Check voltage compatibility (110V vs 220V) and available power in your packaging area to avoid wiring upgrades.
- Bag size flexibility: Look for machines that support adjustable bag width and length to accommodate evolving products or seasonal SKUs.
- Film compatibility and branding: Ensure the film types (PE, laminated films, aluminized film) are suitable for your product’s shelf life and that optional printing services fit your branding plan.
- Maintenance and service: Favor models with clear maintenance guidance, readily available spare parts, and supplier customization options to future-proof your line.
