Mylar Bags Guide – Sizes, Types & Best Uses for Packaging

Packaging plays a critical role in product freshness, shelf life, and brand perception. Among modern packaging solutions, Mylar bags have become the top choice across industries, from food and cannabis to supplements and retail goods.

This complete guide from Mylar Bag Depot will walk you through what Mylar bags are, available sizes, different types, and the best uses; so you can confidently choose the right packaging for your products.

What are Mylar Bags?

Mylar bags are special packaging bags made from layers of polyester film and aluminum foil. This combination creates a strong barrier that helps protect products from air, moisture, light, and odors. Because of this, Mylar bags are commonly used to keep items fresh and safe for a long time.

These bags are popular for packaging products like dry foods, coffee, herbs, and retail items. They are lightweight, durable, and easy to seal, making them perfect for both storage and retail use. Mylar bags also give products a clean and professional look on store shelves.

Common Mylar Bag Sizes and Their Applications

Small Mylar Bag Sizes (1g – 7g)

Small Mylar bags are ideal for lightweight products and compact packaging needs. These sizes are commonly used for herbs and spices, cannabis flower and pre-rolls, small edible portions, and product samples. Their compact form makes them perfect for single-use or trial-size offerings, allowing brands to present products in a convenient, portable, and shelf-ready format.

• 1g Mylar Bags – Best for samples, single-use items, and very small portions.
• 3.5g Mylar Bags – Popular for eighth-ounce packaging with a snug, secure fit.
• 7g Mylar Bags – Ideal for quarter-ounce quantities without bulky packaging.

Medium Mylar Bag Sizes (14g – 28g)

Medium-sized Mylar bags are among the most versatile options in retail and commercial packaging. These sizes work exceptionally well for coffee beans, loose-leaf tea, snack foods, gummies, dried herbs, and specialty food items. They provide the perfect balance between portion size and storage convenience, making them a popular choice for everyday consumer products.
