Foil Bags

Custom foil bags combine barrier packaging performance with a premium metallic aesthetic that standard plastic bags simply can't match. The reflective foil surface creates instant visual premium appeal while the laminate structure provides meaningful protection against moisture and oxygen. Available in multiple formats with full custom printing.

• Metallic foil exterior — premium visual appeal
• Moisture and oxygen barrier construction
• Full-colour custom printing on foil surface
• Heat seal, zipper, and stand-up format options
• Wholesale pricing, no minimum order

For maximum barrier performance, explore our custom mylar bags with full aluminium foil construction.

Foil Bags: Where Barrier Performance Meets Premium Aesthetics

Foil packaging occupies a specific and valuable position in the market: it provides meaningful barrier protection against moisture and oxygen while projecting a premium visual identity that flat plastic bags cannot achieve. The metallic sheen of foil communicates quality before the product inside is even considered.

At The Mailer Boxes, we manufacture custom foil bags with full-colour printing on the metallic outer surface. The result is packaging that performs as barrier packaging and presents as premium retail packaging — a combination that serves both product protection and brand positioning objectives simultaneously.

Foil Bag vs Mylar Bag: What’s the Difference?

Both use metalised or aluminium laminate layers, but the specifications differ:

• Foil bags typically use a thinner aluminium layer optimised for print surface quality and tactile appeal — the exterior metallic look is prominent. Barrier performance is strong for most food and retail applications.
• Mylar bags use a heavier aluminium layer optimised for maximum barrier performance — OTR and WVTR values are significantly lower. The exterior can be metallic or printed over with solid CMYK. Best for long shelf life or highly sensitive products.

For most retail food, confectionery, and cosmetic applications, foil bags provide sufficient barrier performance. For supplements, long-shelf-life food, or products in hot/humid climates, mylar bags are the more protective choice.

Applications for Custom Foil Bags

• Confectionery and snacks: Chocolates, sweets, nuts, and dried fruit in premium foil presentation
• Coffee and specialty tea: Aroma preservation and premium shelf presence
• Cosmetics and beauty: Sachet formats for face masks, hair treatments, and single-use products
• Promotional gifts: Branded confectionery or merchandise in foil presentation packaging
• Event and hospitality: Branded foil bags for corporate gifting and event merchandise

Print Quality on Foil

Printing on a metallic foil surface requires specific ink formulations and different dot gain compensation than printing on white board. Our prepress team optimises artwork for foil printing — adjusting for the metallic substrate, ensuring colour accuracy, and flagging any design elements that may lose detail on the reflective surface. A press proof is provided before production for all first-time designs.

Frequently Asked Questions

Can I use foil bags for hot drinks?

Foil bags are not suitable for hot liquid contents — they’re designed for dry or ambient-temperature products. For hot beverage service, cup sleeves or paper packaging alternatives are appropriate.

Are foil bags recyclable?

Multi-layer foil laminates are not currently recyclable in standard kerbside programmes because the materials cannot be easily separated. This is a genuine sustainability limitation of foil packaging. If recyclability is a priority, discuss alternative barrier coating options — some single-material barrier films are emerging that can be recycled, at some sacrifice of barrier performance.
