Description
Product Overview
Material Structure Breakdown
Material Construction: VMPET / PE (Vacuum Metallized PET / Polyethylene)
- VMPET Vacuum Metallized PET outer layer: Thin aluminum vapor coating creates metallic barrier, blocks light, reduces oxygen and moisture penetration. Lower cost than full aluminium foil composite.
- PE inner sealing layer: Flexible food-grade polyethylene, offers stable heat sealing performance for vacuum packing, good low-temperature resistance.
Important Note: This Food Vacuum Aluminum Foil Bags with VMPET/PE cannot be used for high-temperature retort sterilization. It works for room temperature or cold storage dry food only, not for 121℃ autoclave processing.

Core Product Advantages
- Strong light & moisture barrier: Our Food Vacuum Aluminum Foil Bags feature vapor-metallized coating to block UV light, protect dry goods from fading, rancidity and moisture absorption.
- Cost-effective high-barrier solution: VMPET/PE structure provides near-aluminum-foil barrier performance at a lower cost than full AL composite bags.
- Stable vacuum sealing: PE inner layer forms tight seal on vacuum machines, reduces air leakage risk during long-term storage.
- Flexible customization: Various sizes, thickness and custom printing for food brands and food processing factories.
Application Scenarios
Dried nuts, dried fruits, grains, tea leaves, herbal powder, dehydrated snacks, spice powder, other dry food vacuum preservation.
Important Usage Notes
- Not for high temperature retort sterilization. VMPET coating will crack and barrier performance fails under high pressure steam cooking.
- Avoid sharp hard contents. The thin metallized layer may scratch and lose barrier effect when contacting sharp edges.
- For cooked food requiring 121℃ sterilization, choose full aluminum foil retort pouch (PET/AL/PA/RCPP).
- Optimize heat-seal time and temperature on your vacuum machine to avoid incomplete sealing.
Frequently Asked Questions
Q1: What is the difference between aluminum foil retort bag and transparent PA‑RCPP retort bag?
A: Aluminum foil type achieves ultra‑low oxygen & light transmission for longer shelf‑life, but non‑transparent. Transparent PA‑RCPP can view contents, barrier capability is weaker than aluminum foil version.
Q2: Can this bag handle 135℃ ultra‑high temperature retort?
A: Standard PET/AL/PA/RCPP fits 121℃. For 135℃ high‑retort requirement, material formula needs to be adjusted, please contact our sales team.
Q3: Is custom printing available?
A: Yes, gravure printing service is supported, MOQ depends on bag dimension.
