| Standard PA/PE Coextruded | Polyamide skin layers with a polyethylene sealing layer | 70–150 μm | Approximately 20–80 cc/m²/day | Approximately 2–8 g/m²/day | Good | Fresh beef, pork, lamb, poultry, and routine chilled meat portions | A practical balance of cost, clarity, flexibility, and sealing reliability for high-volume orders. |
| High-Barrier PA/EVOH/PE Coextruded | Polyamide outer layers, ethylene-vinyl alcohol barrier core, polyethylene sealant | 80–160 μm | Typically below 1–5 cc/m²/day | Approximately 1–6 g/m²/day | Good to very good | Longer-distribution chilled meats, sliced meats, cured products, and oxygen-sensitive items | EVOH provides excellent dry oxygen resistance but becomes less effective at high humidity; verify the complete multilayer structure. |
| PA/PE with Enhanced Sealant Layer | Polyamide support layers with a modified polyethylene or ionomer-based sealing layer | 80–160 μm | Approximately 15–70 cc/m²/day | Approximately 2–8 g/m²/day | Very good | Bone-in cuts, sharp-edged portions, marinated meat, and products requiring stronger seals | Suitable where seal contamination from meat juices or fats is a frequent production problem. |
| PET/PE Laminated | Oriented polyester outer film laminated to a polyethylene sealing layer | 70–140 μm | Approximately 1–10 cc/m²/day | Approximately 0.5–4 g/m²/day | Good | Retail-ready portions, printed packs, processed meats, and applications needing a stiff, glossy appearance | Offers strong printability and presentation; confirm flexibility and forming requirements before ordering. |
| High-Barrier PET/EVOH/PE | Polyester outer layer, EVOH barrier layer, and polyethylene sealant | 80–160 μm | Typically below 1–5 cc/m²/day | Approximately 0.5–4 g/m²/day | Good to very good | Premium chilled products, export distribution, and packs requiring high oxygen protection with printed graphics | Select when shelf-life and visual presentation justify a higher material cost; validate seal strength after refrigeration. |
| Shrink Vacuum Bag | Multilayer PA/PE or PA/EVOH/PE film designed for post-packaging shrink | 70–120 μm | Approximately 5–50 cc/m²/day | Approximately 1–7 g/m²/day | Good to very good | Primals, subprimals, bone-in cuts, ham, and irregular products where close conformity is valuable | Requires compatible shrink equipment and controlled hot-water or steam processing; inspect for post-shrink stress. |
| Bone-In Reinforced Vacuum Bag | Heavy-gauge multilayer PA/PE or PA/EVOH/PE with reinforced puncture-resistant design | 120–200 μm | Approximately 10–70 cc/m²/day | Approximately 2–8 g/m²/day | Excellent | Bone-in beef, lamb racks, poultry portions, game meat, and products with sharp contours | Higher material usage can reduce leakage, rework, and product loss; test with the actual bone profile. |
