Weiyi Pack Bag Manufacturer Wholesale Food Packaging Printing Side Gusset Bag with Valve for Coffee Bean 500g Custom Printed

Product Introduction

This coffee‑bean side‑sealed gusseted bag is made of premium aluminum‑foil composite plastic material, specially designed for packaging of coffee beans, coffee powder and ground coffee. Adopting side‑sealed gusseted structure with side gussets to increase bag capacity, it is equipped with a one‑way degassing valve for reliable sealing performance, effectively protecting coffee against moisture, oxidation and aroma loss. Constructed with multi‑layer aluminum‑foil composite structure, the pouch delivers outstanding light‑proof, moisture‑proof, oxidation‑resistant and aroma‑retaining properties. The one‑way degassing valve releases carbon dioxide generated after coffee‑bean roasting while blocking outside air ingress to preserve coffee freshness and extend shelf‑life. It supports full‑color gravure printing for custom‑printed brand logos, product patterns, origin marks, roast degree, ingredient descriptions, brewing instructions, coding area for production dates and more. The high‑end elegant black‑green design with coffee‑cup pattern in 500 g capacity achieves bright and attractive printing effect. Suitable for retail packaging of coffee beans and coffee powder, it is an ideal packaging choice for coffee manufacturers.
