Why Emergency Blankets Are a Must-Stock Item
Emergency blankets, also known as space blankets or thermal blankets, are compact, lightweight, and potentially life-saving. They reflect up to 90% of body heat, making them essential for first aid kits, emergency preparedness, outdoor adventures, and disaster relief. For wholesale buyers, they offer excellent margins due to low manufacturing costs and high perceived value.
Material Types Explained
1. Mylar (BoPET Film)
The most common and cost-effective material. Mylar is a biaxially-oriented polyethylene terephthalate film vacuum-metalized with aluminum.
- Heat retention: Reflects up to 90% of radiated body heat
- Thickness: Typically 12-16 microns (0.012-0.016mm)
- Weight: Approximately 50-60g per blanket
- Cost: Lowest — ideal for bulk and promotional markets
- Drawback: Tears relatively easily, crinkly/noisy, single-use for most practical purposes
2. Polyethylene (PE) Film
Thicker, more durable alternative to Mylar.
- Heat retention: Reflects 85-90% of body heat
- Thickness: 25-40 microns — significantly more tear-resistant
- Weight: 80-120g per blanket
- Cost: Moderate
- Advantage: Can be reused multiple times, quieter than Mylar
3. Hybrid / Laminated Blankets
Premium option combining multiple layers for enhanced performance.
- Typically Mylar film laminated to a PE or fabric backing
- Heat retention: Up to 95%
- Cost: Highest — but commands premium retail pricing
- Best for: High-end outdoor brands, military/first responder kits
Key Performance Specifications
When comparing suppliers, request these specifications:
| Specification | Standard | Premium |
|---|---|---|

Color Options and Their Meaning
- Silver/Silver: Maximum heat reflection. Standard for emergency use.
- Olive/Silver: Military olive on one side for camouflage, silver on the other for signaling. Popular with tactical markets.
- Orange/Silver: High-visibility orange for rescue scenarios. Best for civilian emergency kits.
- Gold/Silver: Premium look, often used for retail products. Slightly lower reflectivity than all-silver.
Folding and Packaging
Packaging significantly affects perceived value and shelf appeal:
- Poly bag with header: Most economical. Good for bulk and promotional items.
- Folded in tin/compact case: Premium presentation. Popular for gift sets and EDC kits.
- Blister card: Retail-ready with space for branding and instructions.
- Multi-pack in box: For family kits, group expeditions, or reseller bundles.
Quality Issues to Watch For
- Delaminating: Metalized layer peels off. Indicates poor lamination quality. Test by folding and unfolding multiple times.
- Inconsistent thickness: Visible thin spots or pinholes when held up to light. Reject these batches.
- Poor folding: Blankets that don't fold back into their original packaging. Ensure factory uses consistent folding jigs.
- Fading ink: Logo or instructions rub off easily. Specify UV-resistant printing.
- Tear at fold lines: Pre-creased lines that tear during unfolding. Indicates film is too thin or folded too tightly.
Compliance and Certifications
Depending on your target market, certain certifications may be required:
- CE Marking: Required for sale in the European Economic Area
- FDA Registration: If marketed with medical claims in the USA
- REACH Compliance: For chemical safety in EU markets
- RoHS Compliance: Ensures no hazardous substances in materials
Conclusion
Emergency blankets are a high-volume, high-margin product that every outdoor retailer should carry. By understanding the material differences, performance specifications, and quality indicators, B2B buyers can source blankets that meet their target market's needs — whether that's budget-friendly bulk Mylar or premium laminated survival blankets. Always request samples and test before placing large orders.
