What kind of flexible packaging is needed for frozen food

The main categories of frozen food:

1. Aquatic quick-frozen foods, such as fish and shrimp, crab sticks, etc.

2. Frozen fruits and vegetables, such as bamboo shoots, edamame, etc.

3. Livestock quick-frozen food, such as pork, chicken, etc.

4. Conditioning frozen foods, such as pasta, fried chicken nuggets, dishes, etc.

The safety and benefits of frozen food depend on four main aspects:

First, the raw materials of the processed food are fresh and of good quality;

Second, the processing process is pollution-free;

The third is that the packaging is not good, and the bags are broken and polluted;

Fourth, the whole cold chain

Frozen food packaging should pay attention to considerations:

1. Packaging standards and regulations.

The second is the characteristics of frozen food and its protection conditions.

3. Performance and scope of application of packaging materials.

Fourth, food market positioning and regional conditions of circulation.

The fifth is the influence of the overall structure and material of the packaging on frozen food.

Sixth, reasonable packaging structure design and decoration design.

Seven is the packaging inspection.

The packaging of frozen food must meet the requirements of large circulation, from production, and transportation to sales, to maintain the quality characteristics of frozen products and prevent the pollution of bacteria and harmful substances.

Frozen food packaging should have five characteristics:

One is to have high barrier properties to prevent the contact of the product with oxygen and the volatilization of water.

The second is impact resistance and puncture resistance.

The third is low-temperature resistance, and the packaging material will not deform or crack even at a low temperature of -45 °C.

The fourth is oil resistance.

Fifth, it is hygienic, preventing the migration and penetration of toxic and harmful substances into food.

Plastic flexible packaging used in the field of frozen food is mainly divided into two categories:

One is composite packaging, which uses adhesives to bond two layers of plastic films together, and most of the adhesives contain harmful substances such as esters and benzene, which can easily penetrate into food and cause pollution.

One is the international advanced multi-layer co-extrusion high barrier packaging. It is produced with green and environmentally friendly packaging materials, with five layers, seven layers, and nine layers. It does not use adhesives but uses more than 3 extruders to combine resin materials with different functions such as PA, PE, PP, PET, EVOH, etc. are melted and extruded together, which has the characteristics of no pollution, high barrier, high strength, and flexible structure. It makes the production process of food packaging and packaging materials pollution-free.

For example, the seven-layer co-extruded high-barrier packaging is composed of more than two layers of nylon, which greatly improves the tensile and tear strength of the packaging. High and low-temperature resistance, storage and transportation resistance, and easy storage can effectively avoid food oxidative deterioration and water loss, and inhibit microbial reproduction, thereby extending the shelf life of frozen food.
