What to Look for in a Flow Wrapper?
When choosing a flow wrapper for your packaging needs, there are several important factors to consider. Here’s a guide to help you make an informed decision.
Product Compatibility
Size Shape: Ensure the flow wrapper can handle the dimensions of your products, whether they are irregularly shaped or standard.
Fragility: If your products are fragile or require gentle handling, make sure the machine offers appropriate adjustments and features to prevent damage.
Speed Throughput
Packaging Speed: Consider the machine’s speed (measured in packages per minute). Ensure it matches your production requirements for volume and efficiency.
Adjustable Speeds: Look for machines with adjustable speed settings to accommodate different production needs or product types.
Sealing Technology
Seal Quality: The machine should provide consistent, airtight seals to ensure product freshness and protection. Check if it offers both fin seals and end seals.
Temperature Control: Ensure it has independent mid-sealing and end-sealing temperature controls to handle different film types accurately.
Sealing Precision: A photoelectric sensor for tracking color marks ensures precise cutting and sealing for consistent package quality.
Film Compatibility
Film Type: Make sure the flow wrapper is compatible with the type of film you use, such as polypropylene, polyethylene, or barrier films for specific applications (e.g., perishable foods).
Roll Stock Capacity: Verify that the machine can handle your roll stock's core diameter and width to ensure smooth operation.
Ease of Operation
User-Friendly Interface: Look for a machine with an easy-to-use control panel and intuitive settings for package length, speed, and sealing adjustments.
Quick Changeover: Ensure the machine allows for fast and simple changeovers between different product sizes or types to minimize downtime.
Maintenance Reliability
Durability: Opt for a machine with a robust build and high-quality components to ensure longevity and minimal maintenance issues.
Ease of Maintenance: Choose a flow wrapper that provides easy access to key parts for cleaning, lubrication, and repairs. Machines with self-diagnostic features can alert operators to potential issues before they cause downtime.
Spare Parts Availability: Check that replacement parts are readily available to minimize downtime if something needs repair or replacement.
Customization Flexibility
Adjustable Settings: Machines with customizable settings for bag length, film tension, and sealing parameters allow you to adapt the wrapper to various product lines.
Optional Features: Consider additional features like gas flushing (for modified atmosphere packaging), date or code printing, or product collating systems if needed for your production.
Size Footprint
Space Requirements: Make sure the flow wrapper fits within the available space on your production floor, and consider the layout of surrounding equipment.
Portability: If you need flexibility in your workspace, check if the machine can be moved or reconfigured easily.
Safety Features
Emergency Stop: Ensure the machine has a clearly accessible emergency stop button.
Guards and Shields: Check for protective guards around moving parts to prevent operator injury.
Automatic Diagnostics: Machines equipped with intelligent diagnostics can detect and alert operators to potential faults, improving safety and reducing downtime.
