Alupack Pouch Wet Pet Food Manufacturing: B2B Procurement & OEM Excellence

A 3-ply Alupack laminate standardly consists of PET (outer layer for thermal resistance and high-definition printing), Aluminum foil (core barrier layer protecting against light, moisture, and oxygen), and CPP (Cast Polypropylene inner sealing layer resistant to retort temperatures up to 130°C). A 4-ply structure adds a BOPA (Nylon) layer between PET and Aluminum foil to dramatically increase puncture resistance, flex-crack resistance, and tensile strength during thermal expansion and hydraulic stress in high-pressure retorts.

Alupack flexible pouches have a significantly thinner cross-sectional profile (typically 12mm to 22mm when lay-flat or stand-up) compared to rigid cylindrical metal cans (73mm to 99mm diameter). Heat transfers rapidly to the geometric center (cold spot) of the pouch, allowing target lethality values (F0 = 12-15) to be reached up to 40% faster. This reduced thermal residence time preserves labile micronutrients (taurine, B-complex vitamins, Omega-3 fatty acids), improves meat protein texture, and prevents over-cooking.

For custom-printed Alupack pouches requiring rotogravure or HD flexographic printing, standard production MOQs range from 30,000 to 50,000 pouches per SKU depending on pouch dimensions (85g vs 500g). Lead time for newly registered private label brands is 45 to 60 days from final artwork approval, encompassing film printing, recipe preparation, pilot batch trial runs, microbiological challenge testing, micro-barcoding verification, and final commercial production.

Our plant in Koźmin Wielkopolski utilizes automated multi-stage impulse heat sealing with continuous thermographic temperature monitoring. During autoclaving, back-pressure (counter-pressure steam-air or water cascade control) is precisely balanced against internal pouch pressure to eliminate seal stress. Every production lot undergoes destructive burst pressure testing (>250 kPa), internal seal-peel force evaluation, dye penetration leak testing, and 100% inline 3D X-ray micro-leak detection.

Yes. Over 70% of our 5,000+ recipes feature single-animal protein sources (such as 100% Duck, Salmon, Turkey, Lamb, or Wild Boar) and grain-free starch matrices (tapioca, sweet potato, pea starch). Our manufacturing facility enforces strict batch-to-batch sanitation protocols and DNA allergen clean-downs between production runs to guarantee zero cross-contamination for sensitive veterinary and hypoallergenic retail lines.

Our facility operates under IFS Food (Version 8 Higher Level), BRCGS Global Standard for Food Safety (Issue 9 Grade AA), and HACCP quality protocols. We also hold ASC (Aquaculture Stewardship Council) and MSC (Marine Stewardship Council) chain of custody certifications for sustainable fish ingredients. We issue complete export documentation including TRACES veterinary certificates, health certificates, microbiological analysis certificates, and local language compliant nutritional packaging declarations for EU, UK, US, Latin America, and Asian markets.

Our in-house animal nutrition R&D center conducts standardized two-bowl intake preference testing (palatability ratio evaluations) alongside standard total-tract digestibility trials. We monitor intake ratios, stool quality scoring (1-5 scale), and sensory consistency across consecutive production batches to ensure your brand delivers superior pet acceptance on the consumer market.

In addition to traditional high-barrier aluminum laminates, we offer high-barrier PP mono-material recyclable retort pouches designed for current circular economy guidelines. These pouches feature specialized SiOx or AlOx barrier coatings that mimic aluminum foil oxygen/moisture barrier levels while remaining fully compatible with polypropylene recycling streams.
