What Makes Our 3 Side Seal Packaging Different?

You need packaging that does more than just hold your product. You need protection that extends shelf life, branding that sells, and reliability that builds customer trust.

Our product uses advanced multi-layer lamination combining PET, BOPA, VMPET, and PE layers. This structure creates a fortress around your products. Moisture stays out. Oxygen can't penetrate. Light damage becomes a non-issue.

Think of it as insurance for your brand reputation.

Superior Barrier Performance

Your spices, coffee, or snacks deserve protection that works 24/7. Our high-barrier films deliver:

• Moisture resistance: Keeps powders free-flowing and fresh
• Oxygen blocking: Prevents oxidation and flavor loss
• Light protection: Shields sensitive ingredients from UV damage
• Grease resistance: Perfect for oily products like nuts and chips

We measure barrier performance rigorously. You get consistent quality, every single order.

Design Features That Solve Real Problems

We've learned what works over 25 years. Here's what we build into every pouch:

• Easy-Tear Notches: Your customers shouldn't need scissors. Our precision-cut notches open smoothly every time.
• Zipper Closures: Resealable options keep products fresh after opening. Perfect for multi-use packaging.
• Hang Holes: Round or euro-slot designs maximize your retail display options.
• Transparent Windows: Show off your product quality while maintaining barrier protection where it counts.

• Scalable Volume: Our 49 converting machines handle everything from pilot runs to multi-million piece orders.

Sustainable Manufacturing

Your customers care about the environment. So do we.

We've invested in imported RTO (Regenerative Thermal Oxidizer) exhaust gas treatment technology. This system captures and neutralizes 98% of production emissions.

Our 100% recyclable 3 side seal packaging options include mono-material PE structures. These pouches maintain barrier performance while meeting circular economy goals.

Perfect Applications for 3 Side Seal Packaging

Spices and Seasonings

Chili powder, paprika, curry blends—these products require moisture control. Even slight humidity turns powder into clumps. Our specialized spice pouches prevent moisture ingress under tropical conditions.

The transparent window feature lets customers see your product quality. The compact flat design maximizes shelf space efficiency.

Coffee and Tea

Freshness determines everything in this category. Our high-barrier films with aluminum foil layers creat oxygen-free environments. Coffee beans and tea leaves maintain their aroma for months.

Tear notches and zipper closures make daily use convenient. Your customers appreciate fresh flavor from the first cup to last.

Snacks and Dry Goods

Chips, nuts, dried fruits—these products require oil resistance and puncture protection. Our PET/PE laminates handle oily contents without leaking or degrading.

The flat profile reduces shipping costs. Lightweight materials lower transportation costs by up to 25% compared to rigid containers.

Frequently Asked Questions

Q: What's the MOQ for custom product?

A: Our MOQ varies based on printing method. Digital printing begins at 500 pieces, perfect for new product launches. Rotogravure printing requires 50,000 pieces but offers lower per-unit costs for larger volumes.

Q: Can you coordinate particular Pantone colors?

A: Completely. Our 11-color rotogravure printing precisely replicates Pantone colors. We give color proofs for your endorsement some time recently production begins.

Q: Do you offer eco-friendly options?

A: Yes. We give 100% recyclable mono-material PE structures and compostable film choices. 

Q: What thickness options are available?

A: Total thickness regularly ranges from 30 to 200 microns, depending on your application. Spice packaging usually uses 100-120 micron films. Frozen foods benefit from 140-160 micron structures for puncture resistance.

Q: Can pouches incorporate degassing valves?

A: Yes. We integrate one-way degassing valves for coffee packaging. These valves release CO2 while preventing oxygen ingress, maintaining optimal freshness for roasted coffee beans.

Q: How do you guarantee print color consistency over huge orders?

A: We maintain strict ink density controls and use spectrophotometers to measure color values throughout production. Print samples from each production run are chronicled for reference.
