Why Your Brand Needs Seal Mylar Bags Now
Product packaging does more than hold items. It tells your brand story, protects your goods, and influences purchase decisions. Seal mylar bags do all three.
Barrier Protection That Works
Seal mylar bags use advanced film technology to create a true barrier between your product and the environment. Light degrades quality in many products. Oxygen causes rancidity in oils and nuts. Moisture ruins spices and dried goods. Our heat seal mylar bags block all three. The result? Products that maintain quality from warehouse to customer shelf.
Cost Effective Wholesale Pricing
We sell seal mylar bags at wholesale prices without sacrificing quality. Order as few as 100 units and get volume discounts at 500, 1000, and 3000 pieces. This means small brands and large retailers both save money. Custom sizes don’t cost extra. Free dieline and free design mean zero hidden fees.
Print Quality That Pops
Your packaging is a silent salesman. Dull printing loses sales. Our seal mylar bags print edge to edge with sharp text, vibrant colors, and accurate registration. We use CMYK or PMS color matching. Coatings include Gloss, Matte, and Spot UV to add dimension and protection to your design.
Understanding How Heat Seal Mylar Bags Work
Heat seal mylar bags require a simple sealing process. The bag arrives open at the top. You fill it with product. Then you seal it using heat and pressure. This creates an airtight closure that holds during shipping and storage.
What Are Heat Seal Mylar Bags Used For
Heat seal mylar bags work across dozens of industries and applications. Common uses include:
- Coffee and loose leaf tea with oxygen barrier protection
- Spices, baking mixes, and dry ingredients
- Snacks, nuts, and confectionery items
- Bath salts, herbs, and wellness products
- Pet treats and supplements
- Empty cereal mylar bags for private label or pantry refill programs
- Craft items and small parts packaging

- Spot UV coating – Selective UV gloss on specific design elements. Creates depth and draws eyes to your logo or product image.
How to Seal Mylar Bags at Your Location
You have options when it comes to sealing your bags. The method you choose depends on your volume and equipment.
How to Seal Mylar Bags with an Iron
This works for small batches, samples, or manual operations:
- Set your iron to medium heat.
- Place a flat board or heat-resistant surface under the bag’s seal area.
- Lay the bag flat with the top seam aligned straight.
- Press the iron along the top seam for a slow count of five seconds.
- Lift the iron and inspect the seal. It should be solid without wrinkles.
- Repeat if needed until the seal feels secure when you squeeze the bag.
How to Seal Mylar Bags with a FoodSaver
A FoodSaver or similar home vacuum sealer works well for medium batches:
- Use the channel adapter or set the machine to narrow seal bar mode.
- Lay the bag flat in the sealing area with the top seam centered.
- Activate the vacuum and heat cycle according to your machine settings.
- The machine pulls air from the bag, then seals with heat.
- Check the seal line for straightness and strength.
- Test bags by squeezing gently to confirm the seal holds.
Commercial Sealing Equipment
If you process thousands of bags, industrial sealers are the answer. We design our seal mylar bags to work with:
- Impulse sealers for hand-fed operations
- Band sealers for continuous production
- Vacuum sealing machines for oxygen control
- Rotary heat sealers for high volume
Vacuum Seal Mylar Bags and Oxygen Barrier Technology
Some products demand extra protection. Coffee oxidizes. Nuts go rancid. Herbs lose potency. For these items, vacuum sealing removes air before the final seal.
What Are Vacuum Seal Mylar Bags
Vacuum seal mylar bags combine our standard barrier film with oxygen absorbers. The vacuum removes ambient air. An oxygen absorber then removes any remaining oxygen from inside the bag. The result? A shelf life that can extend 5–10 times longer than standard sealed bags.
When to Use Vacuum vs Standard Seal
| Product Type | Recommended Method | Storage Length | Best Use Case |
|---|---|---|---|
| Fresh Ground Coffee | Vacuum + Oxygen Absorber | 6–12 months | Specialty roasters and online subscriptions |
| Dried Herbs | Vacuum + Oxygen Absorber | 1–2 years | Bulk orders and wholesale suppliers |
| Snack Mix | Standard Heat Seal | 3–6 months | Retail shelf packaging and impulse sales |
| Spices | Standard Heat Seal | 6–12 months | Retail and food service packaging |
| Nuts and Seeds | Vacuum + Oxygen Absorber | 8–18 months | Premium brands and longer distribution |
