Why Heat Seal Mylar Bags Outperform Standard Pouches?
Heat sealing is simple—but powerful. Once sealed, the Mylar film locks out oxygen, moisture, and odour. That’s why coffee roasters, supplement sellers, and food producers across the UK trust this format. You can tear it open cleanly, reseal it for longer life, and ship it with confidence.
Our Mylar heat seal bags are built from laminated layers of PET and aluminium foil, balancing durability and flexibility. Each layer protects flavour, aroma, and freshness while giving your design a polished, modern look on retail shelves.
Printing & Branding That Do the Selling
We don’t just supply blanks; we help you stand out. Your custom heat seal Mylar bags can feature anything from minimal single-colour branding to full-coverage prints. Using digital or offset printing, we achieve crisp details and colour accuracy across runs of any size.
Want to show off your product? We can include windows or transparent panels without affecting the barrier performance. Prefer something sleek? Try black zip/heat seal Mylar smell-proof bags or even metallic foil finishes in silver, gold, or pink.
Size Options for Every Product
Not every business pack the same amount, so we scale around your needs. Whether you’re after small Mylar heat seal bags for samples or large Mylar foil bags for bulk storage, we produce to your measurements.
Common size categories include:
- Mini packs (3.5g – 10g): for samples, edibles, or coffee tasters.
- Medium pouches (16 × 9 cm – 18 × 26 cm): ideal for snacks, herbs, or tea.
- Large formats (30 cm +): used for dry goods or industrial products.
Every bag is tested for seal strength and puncture resistance before dispatch.
Food-Safe & Certified for Peace of Mind
All Healey Packaging Mylar materials meet UK and EU food contact standards, ensuring that your heat seal Mylar food bags are completely food-safe. The inner aluminium or PET barrier prevents contamination, while the outer layer supports high-definition printing.
If you need compliance documents or batch traceability, we’ll provide them with your order. For regulated industries like nutraceuticals or coffee roasting, our processes help you meet packaging audit requirements with ease.
Eco-Conscious Mylar Options
We get it — going green shouldn’t mean compromising protection. That’s why our eco-friendly Mylar heat seal bags are built to last just as long, seal just as tight, and still look sharp on the shelf. The difference? They’re made using recyclable or part-biodegradable heat-seal laminates that don’t end up hanging around forever.
We’ve tested these materials in real conditions — moisture, storage, transit — and they perform brilliantly. The prints stay crisp, seals stay strong, and the finish still feels premium in hand. For brands working toward sustainability goals, it’s an easy switch that doesn’t mess with quality or freshness.
How the Process Works
We keep production transparent and straightforward:
- Share your brief. Tell us your product type, fill weight, and design style.
- Get your dieline. We’ll prepare artwork specs for accurate layout and sealing margins.
- Approve the proof. Our pre-press team sends a digital mock-up before printing.
- Printing & sealing. Depending on run size, we use digital or offset presses.
- Delivery. Typical turnaround is 10–14 working days across the UK.
Why UK Brands Choose Healey Packaging?
We didn’t build our reputation overnight. It’s come from years of working with real people—food start-ups in rented kitchens, supplement brands shipping their first 1,000 units, and big retailers who can’t afford mistakes in sealing or print.
Our custom Mylar heat seal bags go through hands-on checks at every step, from seal pressure to colour match. Nothing leaves the floor unless it looks and feels right. And when plans change—as they often do before a launch—we adjust without drama. That flexibility is why most of our clients stick with us, year after year.
Your Mylar Heat Seal Bags Questions, Answered
Can I print my logo on the Mylar heat seal bags?
