Custom Rollstock Film
Have you ever wondered if the Mylar bags you use are truly safe for food? For food brands, coffee roasters, and snack suppliers, the packaging you choose affects more than shelf life. It affects customer trust. Many businesses now rely on custom Mylar bags for this reason. But not all Mylar bags are the same. Before you order in bulk, it is worth knowing what makes a Mylar bag truly food-safe.
Why Bag Quality Matters
When buying Mylar bags for food storage, thickness and material are key. Some online sellers list bags as “9 mil,” but that is often the total thickness, not per side. Thin bags tear easily if you store granola, beans, or freeze-dried meals.
At XINDINGLI PACK, we produce customized Mylar bags with accurate thickness ratings. Most commercial brands choose 5–7 mil per side. This range gives strong protection without wasting material or cost. Bags thinner than that risk punctures. Bags thicker than that rarely add value.
Mylar and Food Safety
Mylar, or BoPET (biaxially-oriented polyethylene terephthalate), has been used in packaging since the 1950s. It has two layers: a clear polyester film inside and a reflective metallized coating outside. Only the polyester film touches your food. It is safe for direct contact and free of BPA, phthalates, and harmful plasticizers.
XINDINGLI PACK produces custom printed Mylar bags that meet FDA food-contact standards. This ensures no unwanted chemicals migrate into your food. Your coffee, nuts, or snack bars stay fresh and safe.

What Good Mylar Bags Offer
Good Mylar food storage bags do more than meet safety rules. They keep products fresh and make your brand look professional. High-quality bags give you:
-
Strong Oxygen and Moisture Barrier: Locks in flavor and extends shelf life.
-
Durability for Transport and Storage: Flexible yet puncture-resistant.
-
Custom Branding Options: Fits small runs or large orders.
We work with food brands across the globe. Many choose die cut Mylar bags for creative shapes that stand out on retail shelves.
For Products That Need Extra Protection
Some products require odor control or special handling. Cannabis, tea, and herbal products are good examples. For these, custom Mylar weed bags or custom smell proof Mylar bags work best. They prevent odor leaks and protect potency, giving customers a better experience.

-

How long can food stay fresh in Mylar bags?
With oxygen absorbers and proper sealing, dry foods can last for several years.
Are custom Mylar bags reusable?
Most are designed for one-time use. Heavy-duty bags may be reused if handled carefully.

Yes. Smell-proof designs prevent aroma leaks for herbs, coffee, or cannabis.
