Why Mylar Bags Matter More Than Ever in 2025
Our Mylar bags are high-barrier pouches that use layers of construction to ensure quality protection from oxygen, moisture, and light — making them perfect for long-term food storage, product packaging, and various industrial purposes. Mylar bags, when sealed with oxygen absorbers can actually keep foods fresh for up to 30 years.
And with increasing concerns around shelf life, oxidation, humidity, and supply-chain quality, Mylar bags deliver reliability where traditional packaging falls short.
In this guide, BoxBaba breaks down everything you need to know—from materials and barrier science to thickness selection, sealing methods, oxygen absorbers, size charts, and where to buy the best Mylar bags in the USA.
What Are Mylar Bags?
Mylar is a trademarked polyester film (PET) known for its superior durability and barrier properties.
A typical Mylar bag includes layers of:
PET (polyethylene terephthalate): Provides strength & flexibility
Aluminum foil layer: Blocks oxygen, UV light & moisture
Polyethylene (PE) inner layer: Allows heat-sealing
This laminated structure makes Mylar one of the most effective long-term storage materials available today.
Key Barrier Benefits

Extremely low oxygen transmission rate (OTR)
Excellent moisture resistance
High puncture resistance
Compatible with heat sealing & zipper closures
These properties make Mylar a go-to material for protecting:
Dry foods (rice, beans, oats, grains, pasta)
Herbs & spices
Coffee & tea
Freeze-dried foods
Electronics & documents
Supplements
Seeds & pharmaceuticals
Small consumer goods for e-commerce

Mylar Bag Thickness Guide (Mil Chart)
Thickness is one of the biggest ranking factors for buyer satisfaction. Picking the wrong mil rating leads to tears, punctures, or reduced shelf life.
Below is BoxBaba recommended thickness chart, based on industry standards and use cases:
Thickness | Use Case |
2.5–3.5 mil | Short-term snacks, samples, display pouches |
4–5 mil | Standard food storage, coffee, dry ingredients |
5–7 mil | Long-term food storage (5–30 years) |
7+ mil | Heavy-duty, prepping, bulk grains, long-term survival |
Which Thickness Is Best for Long-Term Storage?
5–7 mil Mylar bags offer the best balance of durability, flexibility, and oxygen resistance.
For 5-gallon buckets, 7 mil is ideal.
