Core Structure:
Aluminum Foil Layer: Acts as the primary barrier against moisture, oxygen, light, and odors.
Composite Lamination:
Outer Layer: PET (polyethylene terephthalate) or nylon for durability, printability, and puncture resistance.
Inner Layer: Food-grade polyethylene (PE) or non-stick coating for safe food contact.
Optional Add-ons:
PVC Window: Transparent window for product visibility (e.g., snacks, chocolates).
Reinforced Seals: Heat-sealable or zip-lock closures for resealability.
Eco-Friendly Variants: Recyclable or compostable films (e.g., plant-based polymers).

Enhanced Product Protection:
Aluminum foil’s superior barrier properties extend shelf life for perishables (e.g., snacks, spices, pharmaceuticals).
Resists punctures and tears during transportation.
Versatile Applications:
Suitable for food (snacks, coffee), cosmetics (serums, powders), and medical supplies (sterile wraps).
Customizable shapes and sizes for niche markets (e.g., pet food, single-serve portions).
Branding & Display:
Stand-up design improves shelf visibility.
High-resolution printing supports vibrant graphics and brand storytelling.
User Convenience:
Easy to open, reseal, or portion-control (e.g., resealable snack bags).
FAQ
Q1: Are these pouches food-safe?
A: Yes! Pouches with FDA-approved aluminum foil and food-grade liners are safe for direct food contact. Specify edible coatings for sensitive items like spices or supplements.
Q2: Can they be used for freezing or high-heat applications?
A: Depending on lamination, some bags withstand freezing (-40°C) or mild heat (up to 100°C). For retort sterilization (>120°C), specialized thermal films are required.
Q3: Do they block odors effectively?
A: Aluminum foil’s dense structure prevents odor transfer, making them ideal for smelly products like gummies, mints, or herbal supplements.
Q4: Can I print custom designs on them?
A: Yes! Use digital or flexographic printing for high-resolution logos, text, and images. Matte/gloss finishes are available.
Q5: Are they eco-friendly?
A: Standard versions are recyclable (check local recycling codes). Sustainable options include biodegradable films or recyclable aluminum layers.
Q6: Do they require special sealing equipment?
A: Most use standard heat sealers, but resealable zippers or Velcro closures may need specific tools.
Q7: What’s the minimum order quantity (MOQ)?
A: MOQ varies by design complexity and material choice. Digital printing supports smaller batches (500+ units), while offset printing requires bulk orders (10,000+).
Q8: Can they be used for pharmaceutical packaging?
A: Yes, if made with medical-grade aluminum foil and compliant with ISO 15378 or other regulatory standards.
