Explore our premium grade selection of custom-printed protective bags, drawstring packs, and metallized flexible packaging materials designed for diverse brand requirements.
A technical guide on how modern laminate technologies protect global product values by optimizing oxygen, moisture, and UV light degradation vectors.
Standard flexible packaging relies on mono-layer polymers that exhibit high permeability rates. In contrast, custom OEM metallic foil bags leverage complex, co-extruded structures incorporating high-purity aluminum foil (AL) or metallized polyethylene terephthalate (VMPET). By sandwiching metallic barriers between external protective printing layers (such as BOPP or PET) and internal food-grade sealant layers (LDPE or LLDPE), our packaging isolates products from external oxidation triggers.
Our research and development indicate that utilizing a 7-micron pure aluminum layer provides an almost absolute barrier against moisture vapor transmission (MVTR ~ 0 g/m²/24h) and oxygen gas transmission (OTR ~ 0 cc/m²/24h). This mechanical property is critical for volatile compounds, premium cosmetics, organic dry foods, and electrostatic-sensitive components.
In global industrial procurement, sourcing agents search for highly specific criteria. Our technical line addresses these queries directly by engineering specific functional features: high mechanical tensile strength to prevent puncture events, tailored heat-sealing window parameters (typically 120°C to 180°C) for automated packing lines, and compliance criteria like FDA-approved direct contact surfaces.
Whether you require holographic laser patterns to elevate high-end cosmetics packaging or anti-static Mylar foil pouches to protect circuit components from electrostatic discharges, LAHD Bag offers bespoke engineering capabilities to meet precise technical parameters.

| Material Layer System | Moisture Barrier (MVTR) | Oxygen Barrier (OTR) | Light Shielding Value | Relative Cost Factor | Primary Use-Case |
|---|---|---|---|---|---|
| Pure Al (Aluminum Foil) Laminations | Outstanding (<0.005) | Outstanding (<0.005) | Absolute (100%) | Premium (High) | Medical devices, military-grade electronics, specialty chemical compounds |
| VMPET (Metallized Polyester Film) | Very Good (0.2 – 0.5) | Good (1.0 – 2.0) | Excellent (>98%) | Cost-Effective (Medium) | Premium coffee packaging, retail bags, cosmetic pouch liners |
| Holographic Laser Foil (PET Base) | Moderate (0.5 – 1.2) | Moderate (1.5 – 3.0) | High Aesthetics (Varied) | Mid-High | Aesthetic retail packaging, custom gifts, promotional accessories |
| Standard Polymer Layers (BOPP/PE) | Low (5.0 – 12.0) | Poor (>100) | Minimal (Transparent) | Budget-Friendly | Temporary shipping sacks, gym bags, standard clothing apparel bags |

How we ensure global compliance requirements across major regions (FDA, EU Food Contact, RoHS, REACH) for high-performance metallic foil products.
For custom packaging deployed in the North American food and pharmaceutical sectors, LAHD Bag strictly adheres to Code of Federal Regulations CFR Title 21. Our metallic laminates are certified to prevent chemical migration under heating conditions, and all direct contact films are FDA-approved food-safe polymers.
All VMPET and laser Mylar rolls sent to Europe conform to Regulation (EC) No 1935/2004. Material formulations are SVHC-free (Substances of Very High Concern) under EU REACH declarations, confirming safety for cosmetic bags, luxury boxes, and electronic accessories.
Our electrostatic discharge (ESD) metallic bags are produced using surface resistivity standards of 106 to 1011 ohms, complying with MIL-PRF-81705D performance standards to deliver safe Faraday cage properties for sensitive electronics.
LAHD Bag is actively researching sustainable materials and smart barrier features to align with global environmental goals.
Traditional multi-material laminates (PET/AL/PE) are historically difficult to recycle due to the challenge of separation. LAHD Bag is developing monomaterial solutions. By utilizing ultra-thin vacuum deposition of aluminum on high-density polyethylene (mono-HDPE), we aim to achieve high-barrier properties while keeping the package fully compatible with domestic recycling streams.
Our research team is combining compostable PLA base films with high-barrier paper packaging to create zero-plastic, biodegradable metallic-appearance pouches. These compostable layers disintegrate under standard industrial conditions without releasing synthetic micro-particles, helping brands meet green packaging regulations.
Direct technical answers to questions regarding MOQ, design guidelines, and performance metrics.
The MOQ depends on the bag dimensions and design complexity. Generally, for custom rotogravure printed pouches, our MOQ ranges from 5,000 to 10,000 units. For customized fabric drawstring pouches with metallic foil prints or standard sizes, MOQs can start lower. Contact our export department for a exact quote tailored to your dimensions.
Yes. Our laminating technicians can formulate custom co-extrusions. If your product requires a high moisture barrier but needs to remain flexible, we can recommend a PET/VMPET/PE sandwich structure. If absolute protection is required, we utilize PET/AL/PE layers to protect your product from oxygen and light degradation.
We provide rotogravure printing, digital printing, and flexographic printing. For high-volume jobs with detailed brand colors, rotogravure provides clean graphic output. For metallic or holographic foil effects, we utilize specialized metallized films with spot-lacquered windows to allow consumers to see the product inside.
Yes. Shenzhen LAHD Bag Co., Ltd. operates under ISO 9001:2015 conditions. All food-grade packaging materials undergo SGS testing to ensure compliance with FDA and EU food contact standards. Raw material traceability documentation is available upon request.
