How to custom coffee packaging bags for roasters?

Roasters care deeply about freshness and shelf impact. But not all packaging bags meet those needs.

Roasters custom coffee bags¹ to protect aroma, block air and moisture, and match branding. Most choose laminated pouches with classic sizes and modern styles like pull-zippers².

When I started customizing bags for roasters, I realized that size, structure, and design choices make a huge difference in product quality and shelf presence.

Why do roasters prefer laminated coffee bags³?

Keeping coffee fresh is more than sealing it in a pouch.

Laminated coffee bags block oxygen and moisture, keeping roasted beans aromatic and fresh. They also resist puncture and heat.

What makes a laminated bag special?

Most high-quality coffee bags use laminated film. These are made by combining multiple layers:

• PET: outer printed layer
• Aluminum foil or metalized PET: middle barrier layer
• LLDPE: inner sealable layer

This combo:

• Prevents air from entering
• Keeps moisture and light out
• Makes sealing easier

Why single-layer bags don’t work

I’ve seen clients lose freshness using only PE or paper bags. These bags:

• Let air in over time
• Don’t seal tightly
• Tear easily

Laminated bags solve all that. And they look better too.

What sizes are best for roasted coffee?

Roasters sell in a few standard weights.

The most common sizes are 100g, 250g, 500g, 1kg, and 2kg. Choosing the right size avoids wasted space and keeps portions consistent.

What sizes fit different markets?

Roasters often choose multiple sizes. For example, 250g for e-commerce, and 1kg for wholesale.

Custom fit to bean density

A 250g light roast takes more space than 250g dark roast. So when we design a custom bag, we also look at:

• Bean type
• Roast profile
• Density

This ensures a snug, professional look.

What coffee bag shapes⁴ are most popular today?

Form affects function. Some shapes seal better, others stand out more.

The most common is stand-up pouch⁵. The trendier option is flat bottom bag with 8 side seals for more stability and space.

Stand-up pouch (Doypack)

Pros:

• Good for smaller sizes (100g–500g)
• Easy to store and ship
• Lower cost

Flat bottom bag (8-side seal)

Pros:

• Premium look
• Stands firm on shelves
• Great for 1kg and 2kg bags
• More printing area

Some roasters I work with shifted from stand-up to flat-bottom. Their feedback: it improved shelf appeal and perceived quality.

Should I choose pull-zipper or standard zip for coffee bags?

Consumers now expect easy reclosable packaging.

Pull-zippers are smoother, easier to open, and give a modern, high-end feel. They're replacing standard zippers in premium coffee bags.

Standard zipper vs pull-tab zipper

Pull-zippers are especially good for:

• E-commerce where unboxing matters
• Café chains with brand identity
• Roasters who want modern edge

What else makes a coffee bag functional and beautiful?

A bag is not just for holding beans. It’s a branding tool.

Good coffee bags combine oxygen barriers, degassing valve⁶s, resealable zippers, and stunning print design. They protect and promote.

Protection features

• Degassing valve: One-way valve lets gas out, blocks air in
• Heat-seal edge: Keeps bag air-tight before first use
• Strong side seams: Prevents rupture in transit

Branding tools

• Matte or gloss finish: Sets the tone—rustic or sleek
• Spot UV or metallic inks: Adds texture and contrast
• Clear windows: Shows product freshness
• Minimal design: Makes small brands feel premium

Combo = protection + emotion

I help roasters design bags that reflect their roast story. Earthy matte for single-origin beans. Sleek gloss for modern espresso blends.

A well-designed bag tells the story before a word is spoken.

Conclusion

Custom coffee bags protect your beans and promote your brand at the same time.
