Stand-Up Zipper Pouches for Specialty Coffee Export: A Flexible Packaging Application in Colombia

Colombia's pouch packaging market was valued at USD 440 million in 2025, with specialty coffee driving significant demand for premium flexible packaging formats. Coffee producers in Colombia's Eje Cafetero region — Caldas, Risaralda, and Quindío — are scaling up stand-up pouch production with degassing valves, resealable zippers, and high-quality barrier laminates to meet retail requirements in Europe and North America. The global coffee pouch packaging market is growing at 3.7% CAGR through 2035.

This illustrative case describes a flexible packaging converter in Colombia that was producing flat-bottom gusset bags for local food brands. As specialty coffee export clients began requesting stand-up zipper doypack formats with degassing valves — a format rejected by German and Dutch retail buyers unless it meets specific dimensional and seal integrity standards — the converter needed to add this capability without replacing its existing lamination equipment.

Requirements

Doypack (stand-up pouch) production with integrated zipper closure
Compatible with three-layer PET/ALU/PE laminate at 80–120 µm thickness (standard for coffee with barrier requirement)
Positional accuracy ≤ 0.5 mm for consistent zipper alignment and consumer opening force
Speed: at least 80 pcs/min on the primary 250 g and 500 g coffee formats
Zipper sealing method that does not damage the barrier layer

Machine Deployed: Reylong JL-L-2TZP600

The High-Speed Multi-Function Stand-Up Zipper Pouch Machine (Model JL-L-2TZP600) produces five bag styles on a single platform. Specifications relevant to this coffee packaging application:

Doypack speed: 35–120 pcs/min
Positional accuracy: ≤ 0.3 mm — exceeds the ±0.5 mm zipper alignment requirement
Zipper sealing: ultrasonic wave (1 group) — no heat applied to the zipper seam, eliminating risk of barrier layer delamination
Film thickness range: 30–180 µm — compatible with standard PET/ALU/PE coffee barrier laminates
Bag width (3-side seal mode): 100–580 mm
Bag length: 50–420 mm (skip function for longer bags)
Full servo-motor control (Panasonic) with PLC touch-screen interface
Frame: 10 mm steel-plate construction

Outcome

Doypack production speed: 110 pcs/min achieved on 250 g format at the standard 80 µm PET/ALU/PE laminate — within rated range
Zipper alignment accuracy: ≤ 0.3 mm confirmed across production runs, meeting European retail buyer specification
Ultrasonic zipper sealing eliminated heat damage to the barrier layer — seal integrity testing passed on first qualification batch
Five bag formats now producible on one machine: three-side seal, three-side seal + zipper, four-side seal, doypack, and doypack with zipper — serving both coffee export and domestic snack packaging clients
