Product Description

Brief Description:  
Frozen product packaging is designed to preserve the quality, safety, and freshness of frozen foods in low-temperature environments. It facilitates the storage, transportation, and sales of these products. For example, in the frozen food section of a supermarket, various types of frozen foods rely on appropriate packaging to maintain their condition.

Detailed Description:  
Frozen product packaging involves the use of carefully selected and combined materials.

- Polyethylene (PE): Often used as the base layer due to its excellent low-temperature resistance and flexibility, ensuring it does not break under extreme cold conditions.
- Polypropylene (PP): Adds strength and rigidity to the packaging, ensuring shape stability.
- Polyester (PET): Enhances wear resistance and transparency, allowing consumers to see the food inside.
- Aluminum Foil: Acts as a key barrier layer, effectively blocking oxygen, water vapor, and light to prevent food oxidation and deterioration.

Bag Types:

- Three-Side Sealed Bags: Compact structure with excellent sealing performance, suitable for small frozen foods like shrimp.
- Self-Supporting Bags: Stand on their own with an outstanding display effect, often used for frozen fruit slices.
- Zipper Bags: Feature a zipper for easy opening and closing, ideal for frozen meat intended for home storage.
- Accordion Bags: With an accordion pleat design, these bags have a large capacity, making them suitable for packaging large volumes of frozen vegetables.

Frozen product packaging also needs to be frost-resistant and puncture-resistant. The printing on the packaging surface uses low-temperature resistant inks to ensure clear display of product information, shelf life, and consumption methods.

For example, a frozen pizza might use a composite structure of PET/aluminum foil/PE with an accordion bag design, featuring tempting pizza images and detailed ingredient instructions.

What is Frozen Product Packaging?  
Frozen product packaging refers to the containers or bags specifically designed to hold, protect, and store frozen foods. It is crucial for maintaining the quality and safety of these products.

Why is it Called Frozen Product Packaging?  
It is named "frozen product packaging" because it is developed to meet the specific preservation requirements of frozen foods, including extreme low temperatures and prevention of moisture condensation and oxidation.

Types of Frozen Product Packaging Bags:

- Three-Side Sealed Bag: Offers strong sealing to prevent cold air leakage and contamination.
- Self-Supporting Bag: Features a bottom design that allows it to stand independently for effective display.
- Zipper Bag: Includes a zipper for convenient multiple openings and better retention of the frozen state.
- Accordion Bag: Designed with pleats for increased capacity, suitable for large-volume frozen products.

Characteristics and Material Parameters:

Features:

- Low Temperature Resistance: Maintains flexibility and durability at low temperatures without brittleness.
- Barrier Properties: Effectively prevents oxygen, water vapor, and odors from penetrating.
- Frost Resistance: Reduces frost accumulation on the packaging surface.
- Puncture and Tear Resistance: Withstands sharp parts of frozen food and transportation pressure.

Material Parameters:

- Film Thickness: Generally between 0.05mm and 0.2mm, adjustable based on product needs.
- Tensile Strength: Typically greater than 15 MPa to ensure mechanical strength.
- Oxygen Permeability: Should be less than 50 cm³/(m²·24h·0.1MPa).
- Water Vapor Permeability: Should be less than 5 g/(m²·24h).

Frozen Product Packaging Process:

1. Raw Material Selection: Choose materials like PE, PP, PET, and aluminum foil that meet food contact standards and low-temperature requirements.
2. Printing Plate Making: Design and create high-precision printing plates.
3. Printing: Utilize gravure or flexographic printing technology with low-temperature resistant inks to ensure quality and durability.
4. Compounding: Bond multiple layers of materials using adhesives or hot pressing to achieve comprehensive performance.
5. Curing: Allow composite materials to cure in a controlled environment to enhance bond strength.
6. Slitting: Cut large rolls of composite material to the appropriate width.
7. Bag Making: Use bag-making equipment to form the bags and perform heat sealing.
8. Quality Inspection: Conduct thorough inspections, including appearance, size, sealing strength, and barrier performance, to ensure quality standards are met.
9. Packaging: Sort, count, and prepare the finished products for shipment.
