Vacuum Pack Bags
Vacuum pack bags are basic flexible packaging that preserve food by creating a low-oxygen, airtight environment through vacuum sealing. They are widely used in fresh meat, seafood, cooked foods, grains, and ready-to-cook meals, making them one of the most common packaging formats for supermarkets and food processors.
Typically, vacuum pack bags are made from food-grade PA/PE multilayer composites. The nylon outer layer provides puncture and tear resistance, while the inner PE layer ensures consistent heat-sealing performance. These bags are compatible with a wide range of external and chamber-type vacuum machines, allowing rapid air removal and secure sealing. By effectively inhibiting the growth of mold, bacteria, and other aerobic microorganisms, they slow down oxidation and spoilage, extending the shelf life of food by three to five times. The bags also feature high transparency to clearly showcase the food, enhancing display appeal at retail. In addition, they exhibit excellent low-temperature resistance, allowing direct placement in refrigeration or freezing environments without cracking or leakage.
Vacuum pack bags are available in both pre-made and roll formats, with thickness options ranging from 70 to 120 μm. They can be customized into three-side seal, back-seal, stand-up, or other structures based on product requirements. All products comply with food contact safety standards, are BPA-free, and odorless, making them suitable for stable, long-term bulk procurement. We offer custom sizing, printing, and structural optimization to ensure the bags match your filling lines and product characteristics, reducing waste and improving operational efficiency.
Leveraging a fully integrated, intelligent production layout and mature lean manufacturing system, we achieve large-scale, highly stable production capacity. Daily output of functional composite film rolls can reach 30 tons, and finished packaging bags can reach up to 2 million units per day. This robust capacity allows us to meet clients' needs for small batch samples, pilot orders, and large-scale orders in the hundreds of thousands to millions, efficiently handling urgent or supplementary orders. We provide reliable, timely delivery for clients worldwide, ensuring high efficiency and zero delays.
