Custom Printed Four Side Seal Coffee Bag Packaging
- Four side seal structure that holds its shape. Four heat-sealed edges keep the pouch square and firm, so front and side panels stay flat and the gusset does not buckle after filling— the structural behaviour buyers expect from a quad seal coffee pouch built for retail display.
- Side gusset plus flat base for shelf and carton. The bag stands unaided on shelf and stacks neatly for export, with usable print area across the front, back, both gussets and the base fold.
- Barrier film protects the roast. A laminated barrier film slows moisture and oxygen ingress to help hold aroma between roasting and brewing. A one-way degassing valve or resealable zipper can be specified if your roast or pack format requires it — confirm with our team before sampling.
- Custom printed, sized to your pack weight. Full-panel custom printing, with bag dimensions and film structure matched to your SKU — from small retail packs to bulk coffee bean packaging for roasters and foodservice.
- Built for B2B supply. As a flexible packaging manufacturer we run OEM and wholesale programmes for coffee brands, private label roasters and importers, holding seal strength and print colour consistent across repeat runs.
Q1: Why is an oriented nylon (NY) layer recommended for large-size dog food bags?
A1: Large pet food bags weighing 2kg to 5kg generate substantial hydraulic force and abrasive friction during dropping and shipping.
Adding an orientednylon layer significantly boosts tensile elasticity and puncture resistance, effectively preventing seam tears and
pinholes caused by sharp kibble.
Q2: Can these large stand-up bags be manufactured with a built-in carry handle?
A2: Yes. For bags designed to hold 2.5kg to 5kg, we can incorporate reinforced punched oval handles or three-hole finger grips in the
top header,making it easy and convenient for consumers to carry the product home from retail stores.
Q3: Does the zipper closure hold up to repeated opening on large bulk bags?
A3: We utilize industrial-grade, wide-flange press-to-close zipper tracks engineered with robust interlocking ribs. This ensures an
airtight snap that resists clogging from kibble crumbs, maintaining reliable resealability across weeks of daily feeding.
Q4: What is the minimum order quantity (MOQ) for custom printed large dog food bags?
A4: Our standard production MOQ is typically depending on specific pouch dimensions,material gauge, and cylinder count.
We also support customized trial production batches for new brand launches.
