With the improvement of people's living standards and quality of life, the quality requirements for food are getting higher and higher. However, the domestic rice market is very irregular, and there are inferior rice hitting the market from time to time. One of the important reasons is the difficulty in storing rice. Therefore, the requirements for rice vacuum bags are also particularly strict.

Here are some of the excellent features of rice vacuum bags:

1. High barrier: The performance of different plastic materials is very different, and the film is coextruded to achieve high barrier effect on oxygen, water, carbon dioxide and odor.

2, strong function: oil, moisture, low temperature freezing, quality, fresh, odor, can be used for vacuum packaging, aseptic packaging, inflatable packaging.

3, low cost: relative to glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, co-extruded film has a greater cost advantage. Due to the simple process, the cost of the produced film product can be reduced by 10-20% compared with the dry composite film and other composite films.

4. Flexible structure design: Different structural design can meet your different quality requirements.

5. High strength: The co-extruded film of rice vacuum bag has the characteristics of good stretching during processing. After stretching the plastic, the strength can be increased accordingly. Plastic materials such as nylon and metallocene polyethylene can also be added in the middle to make it It has more than the composite strength of general plastic packaging, no delamination peeling, good flexibility and excellent heat sealing performance.

6, the capacity ratio is small: co-extruded film can be vacuum shrink packaging, which is unmatched by glass, iron cans, paper packaging.

7, no pollution: transparent vacuum bag does not add adhesive, no residual solvent pollution problems, green and environmental protection.
