High Barrier EVOH Vacuum Packaging Bag Seven Layer Film For Fresh Meat Seafood Frozen Storage

High Barrier EVOH Vacuum Bags Seven Layer Film for Fresh Meat Seafood Frozen Storage

Product Description:

High barrier EVOH vacuum bags use a seven layer coextruded film that combines PA for strength, EVOH for oxygen blocking and PE for sealability. The EVOH core lowers the oxygen transmission rate so fresh meat, seafood and prepared foods keep their colour, aroma and texture for longer.

The structure reduces oxidation and spoilage, which helps lower waste and supports longer chilled or frozen storage. The film stays flexible at low temperature and seals cleanly on standard vacuum equipment.

Bags are food grade, BPA free and available as pre-made pouches or rolls in custom sizes for butchers, processors and food packers. They are intended for single use packing.

Features:

Seven Layer Oxygen Barrier – The EVOH core blocks oxygen and slows oxidation, helping fresh meat and seafood keep their natural colour and flavour for longer.

Extended Shelf Life – Lower oxygen transmission reduces spoilage organisms and delays quality loss during chilled and frozen storage.

Puncture and Abrasion Resistance – The PA reinforcement layer guards against sharp bones and edges, cutting leaks during handling and transport.

Low Temperature Flexibility – The film stays supple in deep freezing, so bags resist cracking and keep an airtight seal at low temperature.

Clean Sealing Performance – The PE inner layer seals reliably on common vacuum machines, giving a strong bond without wrinkles or weak spots.

Food Grade Compliance – Materials meet FDA and EU 10/2011 food contact standards for safe direct food contact.

FAQ:

Q: What materials are your vacuum bags made from?

A: Our vacuum bags are manufactured from multi-layer coextruded films, typically combining PA (nylon) for puncture resistance and PE for sealability. High-barrier options include EVOH layers for superior oxygen protection, with aluminium foil available for complete light and oxygen barrier.

Q: Are your vacuum bags food-grade and safe for direct contact?

A: Yes. All our vacuum bags are manufactured from food-grade materials and comply with FDA regulations and EU 10/2011 food contact standards. They are BPA-free and toxin-safe for all food types.

Q: What is the difference between embossed (channeled) and smooth vacuum bags?

A: Embossed/channeled bags have a textured surface that creates air channels for efficient vacuum extraction, making them suitable for external nozzle vacuum sealers. Smooth bags work best with chamber vacuum machines where air is removed externally and typically offer a lower cost.

Q: What temperature range can these bags withstand?

A: Standard grades handle -40°C for freezing up to 100°C for boiling. Retort grades withstand up to 121°C for sterilization. Sous vide grades maintain integrity at 70-90°C for extended cooking times. Please confirm your specific temperature requirements with our team.

Q: Can the bags be used for sous vide cooking?

A: Yes. Our sous vide grades are specifically designed for low-temperature long-time cooking, maintaining seal integrity and chemical safety at 70-90°C without leaching.

Q: What thickness options are available?

A: Standard thickness ranges from 60μ to 120μ, with custom options available for heavy-duty applications requiring extra puncture protection.

Q: Can I get custom sizes?

A: Yes. We offer custom widths, lengths, and thicknesses to match your specific product dimensions and portion requirements. Minimum order quantities apply for custom sizes.
