Design: Creating packaging that protects food from contamination, spoilage, and physical damage. Packaging must also be easy to open and use in challenging conditions.
Materials: Using durable, lightweight materials such as Mylar, aluminum, or high-density polyethylene (HDPE) for packaging. These materials help preserve the shelf life of the food.
Automation: Employing automated systems to fill and seal food bags efficiently, ensuring uniformity and reducing the risk of contamination.
Manual Checks: Conducting manual inspections to ensure each bag meets quality standards.
The materials used in the production and packaging of SOS food bags are chosen for their durability, safety, and ability to preserve the contents over extended periods. Key materials include:
1. Food-Grade Plastics
- High-Density Polyethylene (HDPE): Often used for water containers and some food packaging due to its strength and resistance to impact.
- Polypropylene (PP): Used for packaging dry goods and snacks, offering excellent chemical resistance and stability.
2. Foil and Mylar
- Aluminum Foil: Provides a barrier against light, oxygen, and moisture, making it ideal for preserving the freshness of food items.
- Mylar: A type of polyester film used to create airtight and waterproof packaging, extending the shelf life of food.
3. Cardboard and Paper
- Cardboard Boxes: Used for outer packaging to protect individual food bags during transportation and storage.
- Paper Liners: Sometimes used inside packaging for additional protection and to absorb moisture.
4. Sealing and Insulation Materials
- Heat Seals: Used to create airtight seals on plastic and foil packaging, preventing contamination and spoilage.
- Insulating Materials: Some SOS food bags include insulated packaging to protect temperature-sensitive items.
