How do you handle post-production support and quality claims?

Supouches offers several material options for sustainable flexible packaging, including recyclable mono-material packaging structures, films containing post-consumer recycled (PCR) material, and high-barrier PE-based options incorporating EVOH where suitable. Our wider material selection also includes PE, PET, aluminum foil, kraft paper, and VMPET, allowing us to develop customized packaging structures according to different product requirements.

We recommend materials based on your product's barrier requirements, shelf-life goals, filling process, and target market rather than selecting materials based on one factor alone. However, recyclability depends on the complete packaging structure and the local collection and recycling systems. PCR content and its suitability for food contact also need to be assessed for each application. Sharing your product details and packaging requirements helps us identify an appropriate material solution.

We select food-contact packaging materials according to your product, filling conditions, and destination market. Depending on the selected materials, Supouches can support documentation requests, including a Declaration of Compliance (DoC) and available supplier material or test reports.

Our facilities are BRC- and ISO-certified, and we also provide information about available material-related documentation. These include FDA 21 CFR-related documents for LLDPE and CPP films, a food-contact test report for foil, and an EU total migration test report for stand-up pouches.

Before production, please share your intended packaging use and any applicable FDA or EU food-contact requirements. This information helps our team review material suitability and identify whether additional testing is needed. By confirming these requirements before production, we can better align the selected packaging structure and supporting documentation with your project's specifications. 

Supouches follows a 3-stage quality control system: incoming material inspection, in-process monitoring, and final inspection before shipment.

We check material specifications and thickness, monitor printing, lamination, dimensions, and seals during production, and inspect finished packaging against the approved artwork and agreed specifications. During pouch production, samples are sent to the laboratory every 2,000–3,000 pieces. Depending on the application, testing may include seal strength, burst resistance, drop testing, oxygen transmission rate (OTR), and water vapor transmission rate (WVTR). Our quality systems are rooted in ISO principles and FDA GMP requirements, with BRC certification supporting consistent packaging quality and early defect detection throughout manufacturing.

Supouches offers digital and rotogravure printing for custom flexible packaging, including printed pouches and rollstock film. Digital printing suits smaller orders, multiple SKUs, and frequent artwork changes, with minimal setup and fast turnaround for prototypes, seasonal runs, or limited editions. Rotogravure printing delivers cost advantages and excellent color consistency for larger production runs through precision-engraved cylinders.

We recommend the optimal method based on your order quantity, design complexity, and delivery needs. Typical production times are 12–17 days for digital printing and 21–30 days for gravure printing after artwork approval and deposit receipt, excluding shipping. Both methods support high-quality results for food, coffee, pet food, and consumer packaging applications.
