What minimum order quantity applies to custom mylar bags?

PackTist's MOQ is 500 units. For brands launching new product SKUs, 500 units provides a production-quality test run that validates design, fill performance, and retail presentation before committing to larger volumes at lower per-unit cost.

How do I spec the right mylar bag size for my product?

Fill weight is the starting point — convert your product's net weight to approximate volume based on density. The bag should stand upright (for stand-up formats) when filled to 80% capacity without tipping. Provide product weight and an approximate volume estimate when requesting a quote for the most accurate size recommendation.

Can mylar bags include sustainable materials?

Partially — bio-based and recycled content flexible films are increasingly available. These provide reasonable barrier performance for moderate shelf-life requirements but don't match full mylar performance for long-term storage applications. For brands with strong sustainability commitments, the trade-off between barrier performance and eco-material use should be evaluated against your specific product's shelf life requirements.

What printing quality is achievable on custom mylar bags?

High-quality flexographic and digital printing in reverse-printed, food-safe ink systems achieves vibrant, brand-quality results on mylar stock. Colors appear rich and accurate on properly specified mylar print stock. Full bleed, photography-quality designs, and specialty color combinations are all achievable.

How does custom printing affect mylar bag costs versus plain bags?

Custom-printed mylar bags cost more than plain alternatives primarily due to print setup costs amortized over the run. At 500 units, the per-unit premium is higher; at 2,500+ units, custom-printed mylar becomes cost-competitive with plain bags plus applied labels. The brand differentiation value of custom print typically justifies the investment at competitive product price points.

Overview

Heat Seal Mylar Bags

No zipper means no interruption in the film — the tightest barrier the format offers.

A full-width seal gives the cleanest closure available, which suits anything opened once. Dwell time, temperature and pressure are set against the film rather than guessed.

Everything you need to know about Heat Seal Mylar Bags.

Mylar (BoPET) film provides oxygen, moisture, and UV barrier performance significantly superior to standard poly bags. The multi-layer construction combines different film types for optimal barrier balance. For products where shelf life and potency preservation are critical — specialty food, cannabis, supplements, botanicals — the performance difference between mylar and standard packaging is directly measurable in product quality over time.

Heat sealing creates an airtight, permanent seal across the bag opening. Impulse heat sealers are the standard for small-to-mid volume operations. For maximum shelf life on dry products, combining heat sealing with oxygen absorbers removes residual oxygen inside the bag. Resealable zipper versions use press-to-close mechanisms for products used across multiple sessions.

Yes — food-contact mylar films meet FDA food contact material standards. Inks used in food-compliant mylar printing are food-safe. For products where food safety documentation is required by retail buyers or regulatory compliance, PackTist can provide food contact compliance certifications for the materials used.
