Food-grade PA+PE Composite Material Delivers Superior Performance
Our vacuum bags utilize a advanced multi-layer co-extruded composite structure that far outperforms ordinary single-layer plastic bags, ensuring full compliance with international food contact safety directives.
PA Nylon Layer Provides Exceptional Puncture Resistance
The outer PA (Nylon) layer provides outstanding mechanical strength, tensile resistance, and tear toughness. It successfully resists punctures from sharp bone fragments, seafood shells, and hard dry goods to prevent post-sealing micro-leaks. Furthermore, its ultimate gas barrier blocks oxygen and CO2 migration to slow down lipid oxidation and mold growth.
PE Inner Layer Secures Airtight Commercial Heat Sealing
The inner food-grade PE (Polyethylene) contact layer is completely non-toxic, BPA-free, and odorless. It offers optimal flexibility and high-efficiency thermal bonding characteristics that fit flawlessly with any vacuum sealing machine. The sealed seams remain completely intact under heavy pressure without liquid seepage or split edges.
Wide Temperature Tolerance Supports Deep Freezing and Sous Vide
The advanced material formula stabilizes perfectly across extreme thermal environments. It withstands deep blast freezing down to -40°C without embracing embrittlement or cracking, while supporting high-temperature boiling, water bath pasteurization, and low-temperature sous vide cooking up to 100°C without any chemical leaching.
Certified Multi-Layer Structure Complies with Global Standards
The physical integration of the co-extruded composite ensures an oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) that sit far below standard commercial benchmarks, satisfying international GB/T1037, GB/T1038, FDA, and European Union food contact directives with zero chemical precipitation.
Versatile Design Accommodates Worldwide Industry Scenarios
Engineered for automated fast-paced packaging lines in large-scale meat processing facilities, seafood slaughterhouses, and pre-made meal factories. They preserve the structural integrity and nutritional properties of raw products throughout long-cycle cold chain transport and high-density stacked warehousing.
Empowers restaurant chains, centralized catering facilities, and fresh supermarkets to practice efficient ingredient portioning, cross-flavor isolation, and pre-packaged meal preparation. Minimizes storage food waste, shortens kitchen setup times, and ensures operational compliance.
Serves as a reliable, heavy-duty consumable specifically tailored for international low-temperature thermal immersion circulators. The material maintains seamless airtightness during long thermal baths, sealing in essential juices, nutrients, and flavors perfectly.
Optimized for cross-border e-commerce stocking and bulk international trade container shipments. The extreme moisture-proof barrier shields agricultural goods, cereals, and dry snacks from high humidity, mold, and pressure fluctuations inherent in maritime shipping routes.
Perfectly meets retail demands on global e-commerce platforms and supermarket shelves. Provides consumers with professional-grade domestic food preservation, maximizing refrigerator organization, avoiding freezer burn, and maintaining pristine food taste.
Provides critical airtight defense for camping meals, hiking rations, and institutional emergency storage. Extremely lightweight, puncture-proof, and compact, these bags endure rough handling in complex outdoor survival environments.

Comprehensive Structural Options Match All Global Machine Types
Featuring dual-sided crystal clear surfaces with pristine surface flatness, these bags maximize product visibility for supermarket fresh shelves. They operate at premium efficiency inside industrial chamber vacuum machines, making them the primary option for large-scale production facilities and offering premium high-definition multi-color surface printing options.
Engineered with a advanced single-sided grid embossing pattern, the built-in air guide channels allow high-velocity air extraction with zero dead zones. Fully optimized for all external clamp/suction style household vacuum sealers, these bags represent our top export volume product for global retail and residential distribution markets.
Designed as endless tubular rolls with no pre-cut length boundaries, allowing users to customize length dynamically to fit items of any scale. This format eliminates structural plastic waste and is highly sought after by cross-border e-commerce sellers due to its excellent transport metrics and immense popularity.
Integrating long-term high-vacuum performance with a durable reusable top zipper lock. After initial vacuum extraction, the consumer can repeatedly open and reseal the container manually for partial portion access, striking an ideal balance between archival storage and high-frequency daily consumption.
Constructed with thickened, heavy-duty specialized PA+PE raw materials capable of handling strict boiling environments up to 100°C and industrial steam sterilization. The bag body guarantees structural integrity without delamination or bursting, making it ideal for international pre-made entrée and ready-meal exports.
Supporting full matte, glossy, or specialty tinted coatings alongside precise multi-color branding alignments. We translate brand logos, barcode frameworks, and multi-lingual consumer guidelines into high-definition shelf displays that reinforce brand authority.
Advanced Manufacturing Execution Secures Unmatched Product Quality
Our automated production lines deliver structural features that guarantee stable operational behavior during high-pressure storage conditions:
Integrated Multi-Layer Co-Extrusion Tech Avoids Delamination: By utilizing advanced co-extrusion blow machinery, the PA and PE raw layers are fused seamlessly at the molecular scale without using solvent adhesives. This creates an extremely consistent thickness profile that eliminates interior air bubbles and chemical odors.
Widened and Reinforced Heat Seams Stop Leakage: The thermal welding boundaries are structurally expanded and reinforced to distribute mechanical load evenly under maximum vacuum conditions. This avoids seam splitting, capillary fluid leakage, and air entry over long storage cycles.
Rounded Corner Engineering Elevates Safety: Finished bags feature precise automated rounded corners rather than sharp edges, preventing manual skin scratches and protecting outer transport boxes from friction damage during shipping.
Pristine Translucency Facilitates Supermarket Inspection: Formulated exclusively from 100% virgin plastic batches, the bags maintain high optical clarity free from fogginess or dark spots, allowing buying agents to quickly verify ingredient quality.
Uniform Micro-Groove Matrix Insures Air Removal: The embossed micro-channel spacing is mechanically calibrated to drive rapid and uniform evacuation, pulling the film tightly around asymmetric foods for a compact, neat display profile.
