Whether conical bags are safe for food storage depends on the type of bag and the food being stored. Here’s a breakdown:

Conical bags made of food-grade materials:

• Generally safe: If the bags are made from materials specifically approved for food contact (like certain plastics or food-grade paper), they are generally safe for storing many types of food.
• Examples: These bags are often used for snacks like popcorn, candy, or nuts.¹
• Considerations: Even with food-grade materials, consider the specific food. For example, oily foods might not be suitable for paper cones as they could soak through.

Conical bags not designed for food:

• Potentially unsafe: Industrial conical bags (also called bulk bags or FIBCs) are used for transporting and storing large quantities of materials like chemicals, construction materials, or agricultural products.² These are NOT meant for food storage.
• Risks: These bags may be made from materials that could leach harmful chemicals into food. They may also not be cleaned or handled in a way that ensures food safety.

Key takeaway:

• Always check for food-grade labeling: If you’re considering using conical bags for food, make absolutely sure they are explicitly labeled as food-grade.
• Consider the food type: Different foods have different storage needs. Dry goods might be fine in paper cones, while moist or oily foods might require a different type of packaging.

In conclusion: Conical bags can be safe for food storage if they are specifically designed for that purpose. Always prioritize food-grade materials and consider the specific food you’re storing.
