With 25 years of manufacturing expertise, we produce these box-shaped pouches using 7 printing lines and 49 converting machines, delivering orders in just 7–20 days. Our multi-layer structures offer excellent oxygen and moisture barriers, while the five-panel design maximizes branding space and provides up to 30% more capacity than traditional pouches. Certified by ISO 9001, BRC, FDA, and SGS, we ensure global compliance and food-grade safety for your products.

What Makes Our Flat Bottom Plastic Bags Different?

Built for Stability and Shelf Appeal

Unlike traditional pouches that slump or tip over, our bags feature a completely flat base. This box-shaped design stands vertically without support. Your products look professional and organized on retail shelves.

The five-sided structure includes front, back, two side gussets, and a flat bottom. This gives you five distinct branding panels. You get maximum visibility from every angle.

Superior Freshness Protection

Our multi-layer film technology blocks three key threats:

· Oxygen barrier – Prevents oxidation and staleness

· Moisture resistance – Keeps products crispy and dry

· Light protection – Shields sensitive ingredients from UV damage

This combination extends shelf life significantly. Your nuts stay crunchy. Your coffee retains its aroma. Your dried fruits maintain their natural flavor.

Premium Visual Impact

We offer up to 11-color rotogravure printing for stunning graphics. Add spot UV highlights to make logos and key elements pop with glossy accents.

Choose from finishes that match your brand:

· High-gloss for vibrant shelf presence

· Soft-touch matte for premium, organic appeal

· Metallic effects for luxury positioning

Perfect Applications for Your Products

Nuts & Dried Fruits

Almonds, cashews, walnuts, and raisins require protection from humidity and oxygen. Our barrier films maintain crunchiness and prevent rancidity. The flat bottom design handles bulk weights easily while showing your product beautifully.

Specialty Coffee & Tea

Preserve volatile aromatic compounds with our high-barrier foil linings. Include one-way degassing valves to release CO2 whereas blocking oxygen ingress. The stable base prevents tipping when bags are partially used.

Premium Snacks

From granola to protein bars, our pouches give the "shelf impact" customers take note. The generous panel space lets your packaging tell your brand story effectively.

Pet Food & Treats

Handle weights from 500g to 5kg with reinforced side gussets. Our puncture-resistant materials withstand sharp kibble pieces. The vertical steadiness works superbly for large-format retail displays.

Frequently Asked Questions

Q1: What is your MOQ?

We offer 500 pieces for digital printing and 20,000 pieces for rotogravure printing. This flexibility help both small businesses and large brands.

Q2: Can I get samples before ordering?

Yes. We provide free stock samples. Custom samples are available after design approval.

Q3: How long does production take?

Digital printing orders finish in 7–10 working days. Rotogravure printing orders take 15–20 days after design approval.

Q4: Do you offer sustainable packaging options?

Absolutely. We provide recyclable mono-PE structures and compostable PLA/PBAT materials. Both options maintain excellent barrier properties.

Q5: Can you print my custom design?

Yes. We support full custom printing up to 11 colors. Our design team can help with artwork preparation to ensure perfect results.

Q6: Will the bags leak at the bottom seals?

No. We use optimized K-seal technology with controlled heat-seal pressure and temperature. This ensures airtight integrity at all gusset intersections.

Q7: Are these bags suitable for vacuum packaging?

Flat bottom bags work best with gas flushing (MAP) rather than high vacuum. The gusseted structure performs superbly with nitrogen or CO2 flushing to preserve freshness.

Q8: What's the difference between matte and glossy finishes?

Beyond aesthetics, matte finishes offer slightly better stackability. Glossy finishes provide vibrant color pop. Both protect your product similarly well.

Q9: Which businesses do you serve?

We supply packaging for coffee roasters, snack brands, pet food producers, health food companies, and fruit packagers worldwide.

Q10: How do you ensure reliable quality?

Every batch undergoes comprehensive testing. We check seal quality, barrier properties, and print accuracy. Our 25 yeas of experience means we capture issues before they reach you.
