Product Overview
Vacuum Pouch is a high-barrier flexible composite packaging bag specially designed for vacuum pumping and airtight sealing. Made of multi-layer food-grade PA/NY+PE composite film, supplied in industrial film rolls and finished vacuum pouches. After vacuum extraction, the pouch fits tightly with the product to eliminate residual air, achieving anti-oxidation, moisture-proof, mildew-proof and fresh-keeping effects. Widely used for meat, seafood, frozen food, nuts, grains, tea leaves, medicinal materials, electronic components and industrial anti-oxidation sealed packaging. Compatible with automatic vacuum packaging machines, suitable for commercial mass production and long-term product storage.
Composite structure options:
NY/PE, PET/PE, NY/AL/PE, PET/VMPET/PE, retort-grade NY/RCPP, transparent/opaque/metalized finish.Available thickness:
8C – 20C (customizable).Functional grade:
ordinary vacuum grade, frozen resistant grade, high-temperature retort grade, puncture-resistant grade.Surface finish:
glossy lamination, matte lamination, custom embossed air channel texture.Optional process:
full CMYK printing, flexo printing, custom size, hole punching and private label packaging.Special function:
low oxygen transmission, anti-puncture, oil-proof, waterproof, freezer-safe. -
Key Features & Benefits
Air-Free Vacuum Sealing & Long Fresh-Keeping
Supports complete air extraction and tight heat sealing. Effectively isolates oxygen to inhibit bacterial growth, preventing food oxidation, discoloration, mildew and deterioration, greatly extending product shelf life.
High Puncture Resistance & Toughness
Adopts high-toughness nylon composite material. Resists piercing from hard bones, nuts shells and granular impurities, avoiding bag breakage and air leakage during vacuum compression and transportation.
Excellent Barrier & Moisture-Proof Performance
Dense multi-layer structure achieves ultra-low oxygen and water vapor transmission rate. Blocks external moisture and peculiar odor, keeping internal products dry, clean and original flavor locked.
Low-Temperature & High-Temperature Resistance
Ordinary grade supports frozen storage; upgraded retort grade withstands 121℃ high-temperature sterilization. Adaptable for refrigeration, freezing and high-temperature cooking scenarios.
Flat Fitting & Neat Packing Effect
Vacuum shrinkage fits the product closely without bulging. Saves storage and transportation space, improves box loading rate and reduces overall logistics costs.

FAQ & Quality Solutions
Vacuum pouch inflates and leaks air after sealing
Optimize heat-sealing temperature and pressure parameters to ensure fully fused sealing edges. Conduct vacuum holding test for 24 hours before mass production to eliminate micro-leakage.
Pouch punctured easily by food debris or bones
Upgrade high-toughness NY thickened composite structure or add anti-puncture layer. Strengthen edge protection for sharp-contained products.
Short fresh-keeping period and easy product oxidation
Upgrade aluminum foil or metalized high-barrier structure, reduce oxygen transmission rate. Customize formula according to product storage cycle.
Film turns white or cracks after freezing
Adopt low-temperature resistant modified formula materials, improve film flexibility under cold environment to avoid brittle cracking.
Printed ink scratches or peels off easily
Apply high-adhesion vacuum-specific ink and surface varnish treatment. Complete full curing process to enhance friction and compression resistance.
Pouch wrinkles severely after vacuuming
Control film tension and flatness during production, optimize vacuum machine matching parameters to ensure neat and smooth fitting effect.
Residual peculiar odor on finished pouches
Select low-odor food-grade raw materials and environmental adhesives. Implement full ventilation and curing process after production to remove residual smell.
Unstable thickness and batch quality difference
Equipped with online automatic thickness monitoring system, stabilize composite and calendering parameters to ensure uniform batch thickness and performance consistency.

Shipping & Logistics Recommendations
Composite film rolls wrapped with waterproof film and edge guards on pallets to prevent moisture absorption and extrusion damage. Finished vacuum pouches packed flat with sealed inner bags + reinforced corrugated master cartons, palletized for long-distance sea freight. Store in dry, ventilated and constant-temperature warehouse; avoid high temperature, humidity and direct sunlight to prevent film aging and barrier attenuation. Stack height ≤1.2m to prevent carton deformation and pouch crease damage. Complete food contact test reports and compliance certificates provided for customs clearance. 24-hour after-sales support for packaging selection and quality problem solving.
