Vacuum Oxygen-Barrier Roll Film is a multi-layer composite packaging roll developed for vacuum sealing processes, compatible with vertical and pillow-type fully automated packaging equipment on the market. Unlike expanded, frozen, and retort films, it does not need to withstand high-temperature sterilization or adapt to quick-freezing low-temperature environments. Its core functions are only two: high-strength sealing and air-locking, and stable barrier against oxygen and moisture. By venting the air inside the bag, it fundamentally inhibits bacterial growth, delaying food oxidation, mold, and spoilage, and is suitable for both room temperature and refrigerated storage.
The core performance requirements are primarily to ensure a tight seal against the product's corners without tearing or leaking air after vacuum sealing. Therefore, the nylon layer is often indispensable to improve puncture resistance and elasticity. Secondly, it requires high and low oxygen and moisture barrier properties to prevent fat oxidation and rancidity. The heat-sealing layer must be of moderate width and have a uniform seal, without creating air pockets under high vacuum temperatures. If subsequent sterilization in an autoclave is required, retort-grade adhesive and a heat-resistant inner layer to prevent delamination are also necessary, and these must also comply with GB 4806 food contact materials standards and have low solvent residue.
Key selection points based on product and process
Ordinary low-temperature refrigerated sauces and marinades → PET/PA/PE; For room temperature long-term preservation + pasteurization/121℃ sterilization → PET/PA/RCPP or PET/AL/PA/RCPP; High-fat, high-salt products choose AL structure for impermeability; For products with sharp corners or bones, PA is essential. Before ordering, it is recommended to perform a vacuum test → let stand → cook → leak/drop test to confirm no slow leaks or interlayer separation before bulk purchasing.
Vacuum Oxygen-Barrier Roll Film Core Advantages
Exclusive venting texture design: The surface features a special embossed/air-guiding texture, ensuring instant air expulsion during vacuuming, creating a tight-fitting, form-fitting effect that effectively prevents food freezing damage.
Multi-layer co-extruded high-barrier structure: Utilizing PA/PE or EVOH multi-layer co-extrusion technology, it acts like a shield, effectively blocking oxygen and moisture, significantly extending food shelf life and freshness.
Multi-layer co-extruded high-barrier structure: Utilizing PA/PE or EVOH multi-layer co-extrusion technology, it acts like a shield, effectively blocking oxygen and moisture, significantly extending food freshness and shelf life. With robust puncture resistance, this product is specifically designed for bone-in meats and hard seafood. Its exceptional toughness prevents punctures from sharp edges, ensuring zero air leakage throughout transportation.
It boasts superior heat-sealing stability with a wide heat-sealing temperature window, maintaining a firm seal even under extremely high vacuum tension.
International food safety certification ensures the production environment strictly complies with international food contact material safety standards such as FDA/BRC, guaranteeing worry-free export.
Many food businesses confuse ordinary packaging films with specialized Vacuum Oxygen-Barrier Roll Films, mistakenly believing that anything that can be vacuum-sealed is suitable. This is actually a major reason for the high spoilage rates of fresh and braised products. The core essence of vacuum packaging is to remove all air from the bag, thereby inhibiting bacterial growth and delaying food oxidation and spoilage. However, inferior roll films have poor tensile strength and weak sealing properties, easily resulting in pinholes, air leakage at the seal edges, and whitening of the film after vacuuming, rendering all previous packaging processes useless. Vacuum-sealing roll film is specifically designed for negative pressure vacuum processes. The film boasts excellent tensile strength and high adhesion, combined with a high-strength heat-sealing layer for a tight, leak-proof seal. It also offers excellent oxygen and moisture barrier properties, as well as puncture resistance. Whether it's fresh meat, dried goods, bulk braised food, or agricultural products, it maximizes the preservation of the original flavor. It doesn't require high-temperature resistance or adaptation to low-temperature flash freezing, making it more versatile and cost-effective. When purchasing, don't just focus on the unit price; sealing performance and raw material safety are the core standards. Choosing the right high-quality vacuum roll film reduces air leakage and spoilage issues, using the simplest packaging method to build a long-lasting preservation barrier for your products.
