Specially optimized for agricultural exports, seafood processing, and beverage packaging lines across Porto, Lisbon, and Algarve.
Portugal's food, agriculture, and manufacturing landscape is undergoing a massive transformation. With a rich heritage in seafood preservation (especially cod and canned sardines), high-quality olive oil exports, and premium coffee roasting, Portuguese brands face growing pressure to improve shelf life while maintaining visual branding. The traditional glass jar or heavy metal tin is increasingly replaced by lightweight, flexible, and sustainable three-side sealing bags.
These pouches provide optimal barrier protection against moisture, oxygen, and ultraviolet light. Especially in key agricultural hubs such as Alentejo and Ribatejo, local producers require specialized barrier laminate structures to ensure their premium products survive long-haul maritime shipping routes from Portuguese ports (Sines, Leixões, and Lisbon) to global destinations.
Furthermore, under strict EU environmental regulations, Portuguese manufacturers must implement packaging that reduces waste taxes while maintaining absolute food safety compliance under EFSA (European Food Safety Authority) regulations.
Providing structural integrity, seal strength, and extended shelf life for premium goods.
This construction is the gold standard for dried foods, coffee, and powdered goods. The vacuum metallized PET layer (VMPET) delivers exceptional oxygen and water vapor transmission barriers (WVTR < 0.5 g/m²/24h), preserving freshness and extending product stability on grocery shelves throughout Europe.
For liquid items, pet foods, and pre-cooked seafood meals requiring high-temperature sterilization, we engineer specialized Nylon (PA) and Cast Polypropylene (CPP) films. These structures withstand pasteurization and retort processes up to 121°C/135°C without delamination or seal failures.
To align with Portugal's green circular economy initiatives and the EU Packaging and Packaging Waste Regulation (PPWR), we offer fully recyclable mono-material PE laminates. These maintain functional barrier protection while being classified as Class 4 recyclable materials.

How our three side sealing bags serve different industries across Lisbon, Porto, and beyond.
Traditional metal cans are heavy and prone to denting. Our specialized laminated 3-side seal pouches are puncture-resistant, offer high barriers to prevent oil oxidation, and come with clean-pour spouts, drastically lowering transport weight.
Sardines, mackerel, and octopus are major exports for Portugal. By utilizing retortable NY+CPP laminates in a flat 3-side sealing format, we offer space-saving packaging that withstands high thermal processing cycles.
From Portuguese coffee roasters supplying cafes in Lisbon to retail shelves, our foil-laminated bags with built-in degasification valves keep specialty roasted coffee beans and ground coffee tasting fresh longer.
