Engineering Ultra-Low OTTR & WVTR Polymer Films for Central Portugal’s Agro-Food, Biomedical, and Industrial Manufacturing Sectors.
Send Inquiry NowHigh-performance barrier laminates engineered to protect food integrity, pharmaceutical purity, and industrial goods across the Centro region of Portugal.
Coimbra, serving as the central economic pivot of Portugal’s Centro Region, represents a dynamic ecosystem where traditional agricultural strength meets cutting-edge technological innovation. From the food-processing clusters surrounding the Mondego River valley to the biotechnology hubs anchored by the University of Coimbra and nearby Biocant Park, local industries face stringent packaging requirements.
Preserving the freshness of regional delicacies—such as Queijo Serra da Estrela, artisanal cured meats, specialty baked goods, and Bairrada viticulture exports—demands Advanced Packaging Systems with micro-engineered vapor barriers. High Barrier Polyethylene Terephthalate (PET) films serve as the primary technological defense against degradation caused by atmospheric oxygen, humidity infiltration, and UV radiation.
How advanced co-extrusion, vacuum metallization, and oxide nano-coatings achieve ultra-low permeation metrics for sensitive Coimbra applications.
Oxygen ingress is the primary cause of lipid oxidation, color fading, and aerobic bacterial growth. Our high-barrier PET films utilize biaxial orientation (BOPET) combined with nano-thin vacuum metallization (VMPET) or PVDC coatings to achieve Oxygen Transmission Rates below 0.5 cc/m²/24h.
Coimbra's oceanic-mediterranean climate exhibits seasonal moisture fluctuations. Our Water Vapor Transmission Rates (WVTR) reach levels as low as <0.5 g/m²/24h, protecting hygroscopic powders, dried agricultural goods, and sensitive pharmaceutical tablets from moisture loss or crispness degradation.
For premium food brands requiring shelf visibility without sacrificing barrier performance, our Aluminum Oxide (AlOx) ceramic coated films deliver crystal transparency with high thermal stability, microwaveability, and metal-detector friendly properties.
| Film Structure Code | Primary Coating / Layer | OTTR (cc/m²/24h atm) | WVTR (g/m²/24h) | Key Application in Coimbra Region |
|---|---|---|---|---|
| PET / AL / PE | Pure Aluminum Foil Lamination | < 0.05 | < 0.05 | Pharma sachets, high-fat dairy, long-shelf coffee exports |
| PET / VMPET / PE | Vacuum Metallized Aluminum | < 0.5 | < 0.5 | Snack foods, roasted nuts, dried fruits, regional meats |
| PET / AlOx / PE | Aluminum Oxide Nano Ceramic | < 1.0 | < 1.0 | Clear window food pouches, microwaveable ready-meals |
| PET / PVDC Composite | Polyvinylidene Chloride Co-extrusion | < 2.0 | < 2.0 | Fresh meat vacuum shrink packaging, cheese wrapping |
| RPET Recyclable Film | Post-Consumer Recycled Core | < 1.5 | < 1.5 | Eco-compliant mono-material sustainable packaging |
Integrating 25+ years of polymer manufacturing expertise with direct global supply chain efficiency.
Yangzhou Benchmark Plastic Co., Ltd. operates 4 state-of-the-art PET sheet extrusion lines with a combined daily production capacity exceeding 100 metric tons. By controlling the synthesis, extrusion, thermal treatment, and slitting in-house, we eliminate intermediate markups and deliver factory-direct pricing to Portuguese packaging converters.
Every roll undergoes rigorous quality testing from raw polymer resin selection to final export packing.
From farm-to-table food preservation to biomedical equipment sterilization, our films fulfill exact technical specifications.
Coimbra is adjacent to famous Portuguese cheese-producing areas. Our PET/PE thermoforming film thermoforms into rigid or flexible bottom webs, while high-barrier lamination top lids lock in aroma and prevent fungal degradation under Modified Atmosphere Packaging (MAP) flushed with Nitrogen/CO₂ gas.
Supporting the Cantanhede and Coimbra biotech cluster, our PET/AL/PE foil composite films provide absolute moisture and light barriers for diagnostic test strips, medical instruments, and pharmaceutical powders requiring extended shelf life and gamma/ETO sterilization resistance.
Engineered for automated fast-speed sealing machinery in Portugal's beverage sector. Easy-peel or lock-seal options compatible with PP, PET, and paper cups prevent leakage during transit while keeping fruit juices, iced teas, and yogurt products fresh.
Navigating global supply chain dynamics requires reliable supplier partnerships. Yangzhou Benchmark Plastic Co., Ltd. provides localized logistics support for clients across Coimbra, Aveiro, Leiria, and Viseu.
