What are the advantages of PP fresh lock boxes?

Fresh lock boxes, also known as air conditioning packaging boxes, are generally made of food grade PP plastic particles, high-temperature plastic, or injection molded. In recent years, with the development of modified atmosphere packaging machines in China

With rapid development and application, the preservation box type has been widely used in China's food industry, and the demand for the purchase of its supporting consumables preservation boxes is also showing a strong trend.

Food safety has always been a focus of national attention, and food quality is not only related to its own materials, but also to packaging boxes, packaging boxes, packaging bags, packaging films, and other consumer goods

The packaging of consumables is related. At present, there are general requirements for PP (polystyrene) materials for food grade packaging plastic consumables. Zhouhei duck, the packaging of fresh meat with cold grain appeared in front of people

The packaging consumables require PP material.

The modified atmosphere packaging of fresh-keeping box u002f uses fresh-keeping gas to replace the air inside the box, and then carries out thermoplastic packaging. It is currently the most effective preservation technology in food packaging technology.

Due to the positive pressure of the gas inside the packaging box, the consumables for modified atmosphere preservation packaging, namely the preservation box u002Fpackagingfilm, have high barrier properties and are made of PP food grade material.

Zhouhei duck Lock Fresh Package essentially refers to the products of Zhouhei duck brand's duck feet, duck feet, duck collarbone, Duck wing tips and other cooked foods packaged with modified atmosphere fresh-keeping technology. Its preservation

The consumables required for packaging design include: 1. packaging boxes, also known as pallets; 2. Packaging film, also known as lamination. They can also be commonly referred to as "fresh lock" in pedestrians and the industry

Boxes, packaging material trays, packaging film, composite film, packaging roll film, etc.

1、 Fresh lock box

1. The new lock box is made of pure PP material, which requires high barrier performance to prevent fresh gas leakage after packaging;

2. New lock box size: The outer diameter of the packaging box is generally 200 * 140 * 55mm or 200 * 140 * 35mm.

2、 Food packaging film

Food packaging film materials. The packaging film is generally composed of two layers of materials: pet/pp, or pa/pp. Cooked foods such as Zhouhei duck also need packaging films with high barrier performance.

2. Packaging Film Style Packaging film can be divided into color film and white film according to whether it is printed or not; According to whether the material is easy to tear, it can be divided into easy to tear film u002Fhard difficult to tear film; According to whether the material is anti fog,

It can be divided into anti fog film and non anti fog film.

3. Food safety lock fresh boxes are generally printed on the middle layer, using benzene free and environmentally friendly product materials and printing.

3、 Customized food packaging film/fresh lock box. Customize packaging boxes/film products according to customer needs. The company has rich experience in food packaging/packaging film design

Currently, there are over 100 packaging box styles available for customers to choose from. The fresh box Zhouhei duck CA packaging machine mainly guarantees the freshness of fruits and vegetables and the delay of cooked food from three technical aspects:

1. The modified atmosphere packaging machine adopts methods to prevent and eliminate the proliferation and reproduction of harmful bacteria;

2. Reduce the aerobic respiration rate of living cells, but do not vacuum to avoid anaerobic reactions (except for cooked food, try to avoid hypoxia u002fbags inside the packaging box);

3. After the completion of the modified atmosphere packaging, we need to refrigerate it in a cold storage at 0 ℃ -4 ℃. Cold storage refrigeration technology can also reduce the activity of live tumor cells and lower their aerobic capacity.
