Stretch Wrapper vs. Shrink Wrapper: Which Packaging Solution is Right for You?
A customer from Peru is looking for a wrapping machine to secure products like paper stacks (75×120×14cm) or notebook cartons (45×54×23cm). Two primary packaging methods dominate the industry: stretch film wrapping and shrink film packaging. Both have distinct advantages, and choosing the right one depends on your product’s needs, budget, and logistics requirements.
First we compares stretch wrappers and shrink wrappers, examining their differences, benefits, and ideal use cases to help you make an informed decision.

1. Key Differences at a Glance
| Factor | Stretch Wrapper | Shrink Wrapper |
|---|---|---|
| Working Principle | Uses mechanical tension to wrap film | Uses heat (130-180°C) to shrink film |
| Film Type | PE/LLDPE stretch film | POF/PE/PVC shrink film |
| Packaging Speed | 20-40 loads/hour (faster) | 15-25 loads/hour (slower) |
| Appearance | Semi-transparent, less sleek | Crystal-clear, tight fit (more premium) |
| Protection Focus | Prevents load shifting & impact | Waterproof, dustproof, tamper-evident |
| Cost per Load | $0.10-$0.25 (cheaper) | $0.25-$0.50 (more expensive) |
| Best for Height | 30cm-2m (ideal for tall stacks) | 20-50cm (too short? Wrinkles may form) |
2. Machine Comparison: Strengths & Weaknesses
A. Stretch Wrapper (Best for Industrial Use)
✅ Best for:
- Heavy loads (paper stacks, building materials)
- High-speed logistics (e.g., warehouses)
- Budget-conscious operations
✔ Advantages:
- Lower cost – No heating required, cheaper film
- Higher efficiency – Up to 40 loads/hour
- Superior load stability – Better for rough handling
❌ Disadvantages:
- Not fully sealed – Not ideal for humid environments
- Less aesthetic – Not suitable for retail display
B. Shrink Wrapper (Best for Retail & Secure Packaging)
✅ Best for:
- Consumer goods (notebooks, cosmetics, food)
- Products needing waterproofing
- High-end branding (sleek appearance)
✔ Advantages:
- Complete seal – Blocks moisture, dust, and tampering
- Premium look – Enhances product presentation
- Tamper-evident – Damaged packaging is obvious
❌ Disadvantages:
- Higher cost – Film + energy costs 30-50% more
- Slower process – Heating/cooling takes time
- Maintenance – Heating elements wear out
3. Film Comparison: Stretch Film vs. Shrink Film
| Property | PE Stretch Film | POF Shrink Film |
|---|---|---|
| Material | Polyethylene (PE) | Polyolefin (POF) |
| Thickness | 15-25μm | 12-20μm (thinner but stronger) |
| Clarity | 75-85% transparency | 90-95% transparency (crystal clear) |
| Recyclability | Widely recyclable (#4 LDPE) | Limited recycling (special handling) |
| Puncture Resistance | Strong (for heavy loads) | Moderate (for lightweight goods) |
| Cost per m² | $0.08-$0.15 | $0.15-$0.30 |
4. How to Choose? Decision Guide
5. Final Recommendations
Use a Stretch Wrapper if:
- You need low-cost, high-speed packaging
- Your product is tall or heavy (e.g., paper stacks)
- Protection from dust/humidity isn’t critical
Use a Shrink Wrapper if:
- You need waterproof, tamper-proof packaging
- Your product is retail-ready (e.g., notebooks)
- Brand image matters (e.g., luxury goods)
Case Study: Paper vs. Notebook Packaging
- Paper stacks (75×120×14cm) → Stretch wrapper (cost-effective, stable)
- Notebook cartons (45×54×23cm) → Shrink wrapper if sold individually, otherwise stretch film for bulk logistics
