When it comes to protecting your product from air, moisture, and time, few packaging options perform as well as custom Mylar vacuum seal bags. Known for their durability, barrier protection, and long shelf life, these bags are especially popular in food storage, cannabis, pharmaceuticals, and electronics. When you add custom sizing, printing, or features, they become even more powerful as a tool for branding, safety, and performance.

This article breaks down what custom Mylar vacuum seal bags are, why they’re so effective, who uses them, and how to choose the right type for your needs.

What Are Custom Mylar Vacuum Seal Bags?

Mylar is a strong, flexible material made from polyethylene terephthalate (PET), valued for its resistance to light, oxygen, and moisture. A Vacuum Seal Bag is designed to be air-tight — using a vacuum sealer to remove all the air before sealing the bag shut.

Put the two together, and custom Mylar vacuum seal bags offer the perfect blend of protection and personalization. You can choose bag dimensions, add logos, choose finishes (matte or glossy), and even include tear notches or hang holes to suit retail display.

Why Use Custom Mylar Vacuum Seal Bags?

1. Extended Shelf Life

Vacuum sealing removes oxygen — the main cause of food spoilage, oxidation, and mold growth. Mylar’s barrier layers take that protection even further.

2. Protection from External Elements

Mylar is resistant to:

  • Moisture

  • Light (UV rays)

  • Odors

  • Punctures

  • Temperature shifts

This makes it an ideal choice for delicate or high-value products.

3. Custom Fit for Your Product

Whether you’re storing half a gram of concentrate or a kilogram of jerky, the bag can be custom-sized and shaped to fit your product perfectly.

4. Branding Power

With custom printing, your vacuum seal bags become brand carriers. You can print:

  • Your logo

  • Product info or ingredients

  • Batch numbers or barcodes

  • Safety certifications

  • QR codes or promotional designs

High-quality printing on Mylar creates a professional, polished look.

5. Tamper Evidence and Consumer Trust

Vacuum sealing provides a visible seal, often with optional tamper-evident features. Consumers can instantly tell if a bag’s been opened or damaged — important for regulated industries like cannabis or pharmaceuticals.

How to Vacuum Seal a Mylar Bag

  1. Place the product inside. Leave some space near the opening.

  2. Use a vacuum sealer. Ensure your machine supports Mylar (not all do).

  3. Seal the bag. Apply heat and suction to remove air and close the bag.

  4. Check the seal. Press gently to make sure no air leaks in.

For some products, oxygen absorbers or desiccants are also used inside the bag to boost shelf life.

FAQs

Q1: Can all Mylar bags be vacuum sealed?
No — some Mylar bags are too thick or aren’t compatible with standard vacuum sealers. Look for “vacuum-sealable Mylar” specifically, or ask your supplier.

Q2: Are custom vacuum seal bags food-safe?
Yes, when sourced from reputable manufacturers, these bags are made from food-grade materials and are safe for direct contact.

Q3: Can I print my logo on vacuum seal bags?
Absolutely. Most manufacturers offer Mylar bags logo printing or full custom printing, even on small runs.

Sustainability and Packaging Waste

Traditional vacuum-sealed bags often rely on plastic. Mylar bags reduce overall material usage and shipping weight. Some manufacturers now offer:

  • Recyclable mono-material Mylar bags

  • Compostable or biodegradable layers

  • Refillable or reusable designs

Ask your wholesale Mylar bags supplier about available eco-friendly options when placing your custom order.

Choosing the Right Supplier

When sourcing custom Mylar vacuum seal bags, look for a packaging partner who offers:

  • Low MOQ (minimum order quantity)

  • Design support

  • FDA- or food-safe certification

  • Fast turnaround times

  • Print sample approval

  • Vacuum compatibility testing

If you're working in a regulated industry, make sure your Mylar bag manufacturer understands your compliance and labeling requirements.
