Frozen Food Packaging Bags Manufacturers

Frozen Food Packaging Bag Manufacturer for Cold-Chain Performance

SC Shanghai New Material Tech. Co.,Ltd. (Shengchang) manufactures high-barrier Frozen Food Packaging Bag solutions engineered for low-temperature storage, transport and retail display. Our range covers vacuum bags, flat-bottom pouches, stand-up pouches and roll film for meat, seafood, ready meals, frozen vegetables and frozen pet food.

We produce 7-layer, 9-layer and 11-layer co-extruded films using PA/PE and PA/EVOH/PE structures. These materials maintain flexibility below -40°C, resist puncture from bone-in products and provide oxygen and moisture barriers that limit freezer burn and oxidation.

Our Frozen Food Packaging Range

Our frozen food packaging family includes two production-ready formats and supports custom structures for specific cold-chain requirements. Each format is configured around the product, filling line and storage profile.

Both formats are available as pre-made pouches or roll film for automatic packaging lines. We also supply related flexible packaging such as Stand up Pouch and Multi-layer Co-extruded Film for frozen applications.

Material and Structure Options

We select the film structure based on the product's moisture and oxygen sensitivity, fat content, sharp edges and expected shelf life. The table below summarises typical configurations for frozen food packaging.

Thickness typically starts at 120 microns and can be increased for heavy-duty or vacuum applications. We also offer anti-fog, high-clarity and recyclable mono-material options where sustainability targets apply.

Application Fit Across Frozen Food Categories

• Meat and poultry: Vacuum and MAP bags with strong seals and high oxygen barriers to prevent freezer burn and discoloration.
• Seafood: Low-temperature flexible films that resist cracking and punctures from shells and fins.
• Vegetables and fruits: Reclosable zipper bags for consumer convenience and moisture control.
• Ready meals: Microwave-safe and boilable bags that transition from freezer to heat.
• Frozen pet food: High-barrier bags with light-blocking layers and easy-open features.

Configuration and Customization Process

We follow a structured customization process to match packaging to your product and line. This covers needs assessment, material selection, structural design, printing and production.

1. Needs assessment: We review product characteristics, market positioning and packaging requirements.
2. Material customization: We select PA/PE or PA/EVOH/PE structures and adjust thickness, layers and barrier properties.
3. Structural design: We tailor the pouch format (flat bottom, stand-up, vacuum) to product shape and storage conditions.
4. Printing and branding: High-resolution printing with custom logos and color schemes.
5. Production and quality control: Multi-layer co-extrusion film blowing under ISO 9001, HACCP, BRC and GMP systems.
6. Delivery: Flexible scheduling and efficient shipping from our Shanghai facility.

Quality Assurance and Certifications

Our frozen food packaging bags are produced under ISO 9001, HACCP, BRC and GMP certified systems. We use 100% brand-new food-grade plastic pellets that comply with FDA and EU food contact standards.

Quality control includes physical testing (tensile strength, puncture resistance, seal integrity), chemical testing (material composition, gas barrier) and environmental simulation (freezing, vacuum, transport). Each batch is traceable from raw material to finished product, and inspection reports are available.

Information We Use to Configure Your Solution

To prepare an accurate proposal, we need the following project inputs. This helps us recommend the right structure, dimensions and features.

• Product type, fat content, moisture sensitivity and presence of sharp edges.
• Target storage temperature and expected shelf life.
• Filling method (manual, automatic, vacuum, MAP) and line speed.
• Bag dimensions, fill weight and desired pouch format.
• Printing requirements: artwork files (.pdf or .ai), colors and finish.
• Order quantity and delivery destination.

We also consider sustainability goals, such as recyclable or biodegradable material options, and can advise on Mono-Material Package structures for frozen applications.

Production Capacity and Delivery

Our Shanghai facility operates two printing lines with a daily capacity of 550,000 packaging bags and 2,500 tons of roll film. Standard production lead time for custom frozen food bags is 15–18 days after artwork approval, depending on order volume and material availability.

We ship globally from Shanghai Port, located 50 km from our factory. Common delivery terms include FOB, CIF and CNF. For urgent orders, air freight via Shanghai International Airport is available.

Frequently Asked Questions

What materials are used in your frozen food packaging bags?

We use PA/PE and PA/EVOH/PE multi-layer co-extruded films, as well as PET/AL/PE composites for high-barrier applications. All materials are food-grade and can be customized for thickness, barrier level and recyclability.

Can your bags withstand temperatures below -18°C?

Yes. Our frozen food packaging bags are designed to maintain flexibility and seal integrity at temperatures as low as -40°C, preventing cracking and delamination during freezing and thawing cycles.

What is the minimum order quantity for custom printed frozen food bags?

For custom printed bags, the MOQ is typically 10,000 pieces per design. For stock plain bags, lower quantities may be available. Please contact us with your specifications for a precise quote.

Do you provide samples for evaluation?

We can provide material samples and stock bag samples for performance evaluation. Custom printed samples are available after artwork confirmation and may incur a plate fee.

What certifications do your frozen food packaging bags hold?

Our production systems are certified to ISO 9001, HACCP, BRC and GMP. We also comply with FDA and EU food contact regulations. Certificates are available upon request.

Can you support sustainable packaging options for frozen food?

Yes. We offer recyclable mono-material structures and biodegradable film options that maintain cold-chain performance. Our team can help balance barrier requirements with sustainability targets.
