How To Choose A Shrink Wrapping Machine？

L-type Shrink Wrapping Machine vs. Pillow-type Shrink Wrapping Machine: How to Choose? Which One is More Suitable?

Choosing between an L-type shrink wrapper and a pillow-type shrink wrapper depends on product characteristics, production requirements, and packaging effects. Below is a detailed comparison and selection guide:

1. Suitable Product Types

• L-type Shrink Wrapper

• Best for: Regular or irregular-shaped products (e.g., boxes, bottles, bundled items, tray packaging).

• Advantages: Handles large, irregular, or multi-piece packages (e.g., beverage multipacks, stationery sets).

• Limitations: Less efficient for flat products (e.g., biscuits, books).

• Pillow-type Shrink Wrapper

• Best for: Single, regular-shaped flat or long products (e.g., chocolate bars, instant noodles, tissue boxes).

• Advantages: Continuous high-speed packaging, ideal for assembly lines.

• Limitations: Cannot handle multi-piece bundles or irregular shapes.

2. Packaging Effect

• L-type Machine:

• Provides 3D wrapping, tightly conforming to the product shape—ideal for full sealing (e.g., moisture/dust protection).

• Pillow-type Machine:

• Creates a "pillow" shape with sealed ends, offering a large display area (e.g., for retail visibility).

3. Production Efficiency

• L-type Machine:

• Intermittent operation, slower speed (~10-30 packs/min), suitable for small/medium batches or varied products.

• Pillow-type Machine:

• Continuous high-speed operation (up to 100+ packs/min), ideal for mass production of uniform products.

4. Cost & Space Requirements

• L-type Machine:

• Lower initial cost but requires additional sealing/cutting equipment; occupies more space.

• Pillow-type Machine:

• Compact and integrated, saving space, but high-speed models are more expensive.

5. Selection Guide

• Choose L-type if:

• Products vary in shape or require bundling.

• Full-wrap sealing is needed (e.g., waterproofing, tamper-proofing).

• Production demands flexibility over speed.

• Choose Pillow-type if:

• Products are flat or uniformly shaped.

• High-speed, large-volume output is critical.

• Transparent retail-ready packaging is preferred.

Additional Considerations

• Material Compatibility: Both work with POF, PE, and other shrink films, but pillow-type machines require more consistent film thickness.

• Automation: Pillow-type wrappers integrate more easily into full-auto lines, while L-type may need manual loading.

Match the machine to your specific needs. If possible, request a sample test from suppliers before finalizing your choice.
