Maximum Food Freshness with Mylar Storage Bags
Mylar bags are a powerful tool for extending the shelf life of your food. These bags create an optimal environment by blocking air, light, moisture, and pests. Here’s a step-by-step guide to using Mylar bags effectively:
Gather Your Supplies:
- Mylar Bags: Choose the mylar bag size based on your food items.
- Oxygen Absorbers & Desiccants: These control moisture and oxidation.
- Heat Sealer: Creates a secure closure.
- Optional: Food-grade buckets/containers for added protection.
Prepare Your Food:
- Ensure your food is clean, dry, and free of contaminants before storage.
- Mylar bags are perfect for grains, rice, beans, pasta, dry fruits, flour, and sugar – all susceptible to spoilage from moisture.
Control Moisture and Oxidation:
- Oxygen Absorbers: Remove oxygen to prevent spoilage and bacteria growth. Add the recommended amount based on your food’s packaging or manufacturer instructions.
- Desiccants: Absorb excess moisture, maintaining freshness.
Pack and Seal:
- Fill your mylar bag with food, leaving room for expansion. Overfilling can hinder sealing.
- Use a heat sealer to carefully close the bag, ensuring a tight and secure seal. Apply steady pressure while running the sealer. Double seals offer extra security.
- Optional: Remove any remaining air by gently pressing down on the contents or using a vacuum sealer attachment. Less air equals longer shelf life.
Label and Store:
- Clearly label the bag’s contents and packing date. Follow “First In, First Out” (FIFO) by using older items first.
- Store sealed bags in a cool, dark, and dry location, away from extreme temperatures and direct sunlight.
- Consider using food-grade containers for additional protection from pests and environmental elements.
Maintain and Monitor:
- Regularly check your mylar bags for tears, punctures, or broken seals. If compromised, transfer the contents to a new bag and seal it properly.
- Shelf life for mylar bags for food storage can extend to several years depending on the food type and storage conditions.
- Replace oxygen absorbers and desiccants periodically to maintain freshness.
- By following these steps, you can effectively utilize mylar bags to keep your food fresh and enjoy it for longer periods.
Mylar Bags: Safe for Ovens or Not?
Some people reheat food directly in its packaging, and a common question is whether Mylar bags are oven-safe. The answer is: it depends!
Standard Mylar Bags (LDPE): These are not suitable for oven use. When heated, LDPE can release strong plastic odors and potentially harm food.
Mylar Bags for Cooking (RCPP): Look for Mylar bags specifically made with RCPP material. These are designed to withstand oven temperatures without compromising food quality.
Why It Matters: Understanding the difference between LDPE and RCPP is crucial before buying Mylar bags. Always ensure the packaging is suitable for your intended use, whether it’s storage or cooking.
A Tip for Savvy Shoppers: Before purchasing any product, make sure you understand its functionalities and limitations, including both the packaging materials and their appropriate uses.
Ensuring Your Mylar Bags are Food-Safe
Mylar bags often consist of multiple laminated layers. Since food safety is paramount, here’s how to confirm your bags are BPA-free and FDA-approved for food contact:
1. Verify Material Usage:
Clarify with your manufacturer that only LDPE or RCPP materials are used in layers directly touching the food.
2. Request Testing Documentation:
Ask for a BPA-free testing pass report and an FDA food-grade testing pass report to guarantee your Mylar bags meet necessary safety standards.
3. Independent Testing:
For added peace of mind, request samples from the same batch as your order, specifically the inner LDPE or RCPP layers.
You can then send these samples to a reputable laboratory like SGS or the FDA (US) for independent testing.
By following these steps, you can ensure your mylar bags are safe for food storage and handling. Don’t hesitate to ask your manufacturer for these certifications to guarantee food-grade quality.
